BMW Motorrad has a long tradition in pointing out new ways and thoughts for the topic „mobility on two wheels“. For that, again and again many studies were presented in the past giving views to the future. The experimental vehicle eRR, created as a project with the Technical University of Munich, embodies an idea of an electric powered supersport motorcycle made by BMW Motorrad.
Already a couple of years ago, BMW i showed the BMW Group’s visionary and sustainable approach with the vehicles BMW i3 and i8 and their revolutionary design principles (aluminum chassis and passenger cabin made from carbon fibre) and BMW Motorrad’s C evolution proved, that zero emission, riding fun and practicability do not exclude themselves.
With presenting the experimental vehicle eRR BMW Motorrad goes one step forward and shows the possibilities of an all-electric drive in a supersport motorcycle. Regarding design and chassis technology the eRR leans on the supersport motorcycle S 1000 RR, however using an all-electric drive.
Stephan Schaller, Head of BMW Motorrad, emphasizes: „Since their market launch, the RR is giving the creeps to motorsport athletes. If acceleration, handling or topspeed – the RR is setting standards. However, if acceleration on the first metres, up to 50, 60 kph, is the point, the RR’s 199 bhp have to admit defeat by another BMW product: the C evolution with its electric drive.
We asked ourselves: What happens when combining a sport motorcycle and an electric drive? The experimental vehicle eRR brings the topic zero emission and electric drive on a new, more fascinating level."
BMW Motorrad will announce technical details of the eRR at a later date.
Today at the Tokyo Motor Show 2015, Nissan Motor Co., Ltd. unveiled a concept vehicle that embodies Nissan's vision of the future of autonomous driving and zero emission EVs: the Nissan IDS Concept.
Presenting at the show, Nissan president and CEO Carlos Ghosn said: "Nissan's forthcoming technologies will revolutionize the relationship between car and driver, and future mobility."
After leading the development and expansion of EV technology, Nissan once again stands at the forefront of automotive technology. By integrating advanced vehicle control and safety technologies with cutting-edge artificial intelligence (AI), Nissan is among the leaders developing practical, real-world applications of autonomous drive technology.
In August 2013, Ghosn said that by 2020 Nissan plans to equip innovative autonomous drive technology on multiple vehicles. Progress is well on track to achieve this goal.
Nissan Intelligent Driving is Nissan's concept of autonomous drive technology and represents what Nissan believes next-generation vehicles should be. "Nissan Intelligent Driving improves a driver's ability to see, think and react. It compensates for human error, which causes more than 90 percent of all car accidents. As a result, time spent behind the wheel is safer, cleaner, more efficient and more fun," continued Ghosn.
By 202X, expect to see Nissan Intelligent Driving technology deployed on cars in cities around the world.
The Nissan IDS experience
Some have compared a future with autonomous drive to living in a world of conveyer belts that simply ferry people from point A to B, but the Nissan IDS Concept promises a very different vision of tomorrow. Even when the driver selects Piloted Drive and turns over driving to the vehicle, the car's performance — from accelerating to braking to cornering — imitates the driver's own style and preferences.
In Manual Drive mode, the driver has control. The linear acceleration and cornering are pure and exhilarating. Yet behind the scenes, the Nissan IDS Concept continues to provide assistance. Sensors continually monitor conditions and assistance is available even while the driver is in control. In the event of imminent danger, Nissan IDS Concept will assist the driver in taking evasive action.
In addition to learning, the Nissan IDS Concept's AI communicates like an attentive partner. From information concerning traffic conditions, the driver's schedule to personal interests, Nissan IDS Concept's AI has what is needed to help create a driving experience that is comfortable, enjoyable and safe.
Design — Together, we ride
"A key point behind the Nissan IDS Concept is communication. For autonomous drive to become reality, as a society we have to consider not only communication between car and driver but also between cars and people. The Nissan IDS Concept's design embodies Nissan's vision of autonomous drive as expressed in the phrase together, we ride," says Mitsunori Morita, Design Director.
Two interiors enable two ways for the driver to enjoy the experience. Together, we ride is clearly demonstrated in the interior design. "The Nissan IDS Concept has different interiors depending on whether the driver opts for Piloted Drive or Manual Drive. This was something that we thought was absolutely necessary to express our idea of autonomous drive," says Morita.
Even though it is a hatchback, the Nissan IDS Concept's long wheelbase enables comfortable seating space for four adults. But the cabin becomes even more spacious when the driver selects Piloted Drive. In this mode, the steering wheel recedes into the center of the instrument panel and a large flat screen comes out. Various driving-related operations are handled by AI, voice and gestures from the driver. The interior, which is comprised of natural materials such as mesh leather, is illuminated by soft light. All four seats rotate slightly inward, facilitating easier conversation. It's like relaxing in a living room.
When the driver selects Manual Drive, the roomy interior transforms to put the driver in control. All seats face forward. The steering wheel, which takes styling cues from reins for horse riding, appears along with driving meters and a heads-up display that shows route and other driving information. Interior lighting switches to blue, stimulating the ability to concentrate. Nissan's use of hollow-structure A-pillars helps ensure excellent visibility by reducing blind spots and also contributes to the feeling of open space.
"In every situation, it is about giving the driver more choices and greater control. And the driver will remain the focus of our technology development efforts," Ghosn said at the show.
The transformation to Manual Drive can be carried out with ease through a switch between the front seats called the PD Commander. This is the only control the driver can physically operate when the car is in Piloted Drive: when the driver is ready to take over driving, a physical action should initiate the change.
Exterior design
For autonomous drive to be widely accepted, people need to fully trust the technology. Through its innovative communication capabilities, the Nissan IDS Concept promotes confidence and a sense of harmony for those outside the car as well. Various exterior lights and displays convey to pedestrians and others the car's awareness of its surroundings and signals its intentions. The car's side body line, for example, is actually an LED that Nissan calls the Intention Indicator. When pedestrians or cyclists are nearby, the strip shines white, signaling that the car is aware of them. Another electronic display, which faces outside from the instrument panel, can flash messages such as "After you" to pedestrians. This natural, harmonious system of communication signals a new future with cars.
Advanced aerodynamic performance for greater driving range
Design Director Mitsunori Morita says: "By the time Nissan Intelligent Driving technology is available on production cars, EVs will be able to go great distances on a single charge. Getting to this point will, of course, require the further evolution of batteries, but aerodynamic performance is also very important. We incorporated our most advanced aerodynamic technology in the design of the Nissan IDS Concept."
The height of the full carbon fiber body was constrained to 1,380 mm, sharply minimizing aerodynamic drag (Cd). Positioning the tires close to the corners of the body maximizes interior space while enabling a wrap-around cabin design. Nissan selected large-diameter wheels for high-performance and sportiness, but used very thin 175-size tires to minimize air and roll resistance. The wheels have a layered design suggestive of thin fins that create tiny vortexes of air flow on the wheel's surface. This design further contributes to smooth air flow.
The icicle pattern on the Nissan IDS Concept's grille symbolizes a pure and clean design — perfect for an EV. Shaped like a stack of ice blocks, the grille pattern appears transparent. The car's bluish satin silver body color heightens the impression of a comfortable and secure cabin space.
Highly evolved EV technology for long-distance driving
At Nissan's annual shareholders meeting in June, Executive Vice President Hideyuki Sakamoto said: "Our zero emission strategy centers on EVs. We are pursuing improved electric powertrain technologies, such as motors, batteries and inverters, which will enable us to mass produce and market EVs that equal or surpass the convenience of gasoline-powered cars."
The Nissan IDS Concept is fitted with a high-capacity 60 kWh battery, and thanks to its outstanding aerodynamics, low stance, flowing form and reduced weight due to its full-carbon-fiber body, the vehicle is designed to also meet the need to drive long distances. Other technologies on the Nissan IDS Concept include Piloted Park that can be operated by smartphone or tablet, and wireless charging technologies. Through these, the driver can leave parking and charging to the car.
Nissan's targets — Zero traffic fatalities and zero emissions
In order for our car-based society to be sustainable, complex issues ranging from sustainable energy supplies to climate change, air pollution and traffic safety must be addressed. At Nissan, we have set zero fatalities and zero emissions as aspirational targets in our mission to help create a sustainable car-based society.
Over 90 percent of traffic accidents are caused by human error. Nissan IDS Concept's extensive system of sensors and AI are designed to provide enhanced safety performance compared to a human driver. This technology brings us a step closer to the goal of zero traffic fatalities.
EVs produce no CO2 emissions and their batteries can store energy from renewable sources and turn it into electricity for homes and buildings. As the number of EVs increases, entire communities will be able to harness their power as part of a sustainable energy plan. Then, as EVs come to play a central role in energy supply, we will come that much closer to becoming a zero emission society.
Nissan believes that the Nissan IDS Concept will evolve into a leading innovation for next generation mobility and our quest for making these "two zeroes" a reality.
Featuring Nissan's most advanced safety, driving-control and EV technology — all taken to a new level by AI — the Nissan IDS Concept is a compelling showcase of a promising future.
The road car project that Adrian Newey is working on with Red Bull and Aston Martin appears to be picking up steam, and there are rumors that it could be an electric car.
Newey seems to have no interest in building a hybrid hypercar four years after the McLaren P1, LaFerrari and Porsche 918 Spyder. As previously discussed, these examples are very much first generation 'mild' hybrids.
What does interest him is a car that Autocar says advances technology and the involvement of the driver. That would be an electric supercar. Newey reportedly wants his car to hold the same sort of place in history as Gordon Murray's McLaren F1.
Sources suggest that Aston Martin shareholder Mercedes-Benz wants to be involved in the project, both to create a connection with Red Bull’s younger audience and to have a technical involvement in what could be a landmark product. As such, it is said to be pushing for its performance arm, AMG, to work with Newey.
As AMG are responsible for designing the only production supercar with true all-wheel-drive torque vectoring (Mercedes SLS AMG Electric), any collaboration between AMG and Adrian Newey could spawn a vehicle to seriously eclipse the current generation of hybrid hypercar.
In presenting the Mission E at the IAA in Frankfurt, Porsche is introducing the first all-electrically powered four-seat sports car in the brand's history. The concept car combines the unmistakable emotional design of a Porsche with excellent performance and the forward-thinking practicality of the first 800-volt drive system. Key specification data of this fascinating sports car: four doors and four single seats, over 600 hp (440 kW) system power and over 500 km driving range. All-wheel drive and all-wheel steering, zero to 100 km/h acceleration in under 3.5 seconds and a charging time of around 15 minutes to reach an 80 per cent charge of electrical energy. Instruments are intuitively operated by eye-tracking and gesture control, some even via holograms – highly oriented toward the driver by automatically adjusting the displays to the driver's position.
Drive system: over 600 hp with technologies from endurance racing
The drive system of the Mission E is entirely new, yet it is typical Porsche, i.e. proven in motor racing. Two permanent magnet synchronous motors (PMSM) – similar to those used in this year's Le Mans victor, the 919 hybrid – accelerate the sports car and recover braking energy. The best proof of a Porsche is 24 hours of top racing performance and a 1-2 finish. Together the two motors produce over 600 hp, and they propel the Mission E to a speed of 100 km/h in less than 3.5 seconds and to 200 km/h in under twelve seconds. In addition to their high efficiency, power density and uniform power development, they offer another advantage: unlike today's electric drive systems, they can develop their full power even after multiple accelerations at short intervals. The need-based all-wheel drive system with Porsche Torque Vectoring – which automatically distributes torque to the individual wheels – transfers the drive system's power to the road, and all-wheel steering gives precise, sporty steering in the desired direction. This makes the Mission E fit for the circuit race track; its lap time on the Nürburgring Nordschleife is under the eight-minute mark.
Everyday practicality: convenient and quick charging, over 500 km driving range
It is not just passionate sportiness that makes up a Porsche but also a high level of everyday practicality. Accordingly, the Mission E can travel over 500 km on one battery charge, and it can be charged with enough energy for around 400 km more driving range in about fifteen minutes. The reason: Porsche is a front-runner in introducing innovative 800-volt technology for the first time. Doubling the voltage – compared to today's electric vehicles that operate at 400 volts – offers multiple advantages: shorter charging times and lower weight, because lighter, smaller gage copper cables are sufficient for energy transport. A moveable body segment on the front left wing in front of the driver's door gives access to the charging port for the innovative "Porsche Turbo Charging" system. Via the 800-volt port, the battery can be charged to approximately 80 per cent of its capacity in around 15 minutes – a record time for electric vehicles. As an alternative, the technology platform can be connected to a conventional 400-volt charging station, or it can be replenished at home in the garage via convenient inductive charging by simply parking over a coil embedded in the floor of the garage from which the energy is transferred without cables to a coil on the car's underbody.
Low centre of gravity for superior driving dynamics
Another feature that is typical of a Porsche sports car is a lightweight concept with optimal weight distribution and a low centre of gravity. The battery mounted in the car's underbody, which is based on the latest lithium-ion technology, runs the whole length between the front and rear axles. This distributes its weight to the two drive axles uniformly, resulting in exceptionally good balance. In addition, it makes the sports car's centre of gravity extremely low. Both of these factors significantly boost performance and a sports car feeling. The body as a whole is made up of a functional mix of aluminium, steel and carbon fibre reinforced polymer. The wheels are made of carbon: the Mission E has wide tyres mounted on 21-inch wheels in front and 22-inch wheels at the rear.
Design: fascinating sports car with Porsche DNA
Every square inch, every angle, every radius of the Mission E reflects one thing above all else: emotional sportiness in the best tradition of Porsche design. The starting point is the sculpture of a sport saloon with a low height of 130 cm with sports car attributes from Zuffenhausen that embodies visible innovations such as its integrated aerodynamics. Distinctive air inlets and outlets – on the front, sides and at the rear – typify the body's full flow-through design that enhances efficiency and performance. Integrated air guides improve airflow around the wheels, for instance, and air outlets on the sides reduce overpressure in the wheel wells, thereby reducing lift.
The much reduced sculpting of the front end shows a classic Porsche sweepback, and it relates the concept car to the 918 Spyder and Porsche race cars. A new type of matrix LED headlights in the brand's typical four-point light design captures the viewer's gaze. Integrated as an element hovering in the airflow of the air inlet, they lend a futuristic character to the front end. The four LED units are grouped around a flat sensor for assistance systems whose border serves as an indicator light. Distinctive front wings and an extremely low-cut bonnet reference 911 design. As in the 911 GT3 RS, a wide characteristic recess extends from the overlapping front luggage compartment lid up and over the roof. The line of the side windows is also similar to that of the 911, however, with one important difference: two counter-opening doors enable convenient entry – without a B-pillar. Another difference: instead of the classic door mirror, inconspicuous cameras are mounted on the sides that contribute to the car's exceptional aerodynamics.
The rear design underscores the typical sports car architecture. The lean cabin with its accelerated rear windscreen, which draws inward at the rear, creates space for the sculpted shape of the rear wings that only a Porsche can have. A three-dimensional "PORSCHE" badge illuminated from inside hovers beneath an arch of light that extends across the entire width in a black glass element.
Interior: light and open with four single seats
The interior of the Mission E transfers all of the traditional Porsche design principles into the future: openness, purist design, clean architecture, driver orientation and everyday practicality. The all-electric drive concept made it possible to fully reinterpret the interior. The lack of a transmission tunnel, for instance, opens up space and gives a lighter and more airy atmosphere to the entire interior. Race bucket seats served as inspiration for the four single seats. Their lightweight design is weight-saving, and it gives occupants secure lateral support during dynamic driving. Between the front seats, the centre console – elegantly curved like a bridge with open space beneath it – extends up to the dashboard.
Display and control concept: intuitive, fast and free of distractions
A new world based on an innovative display and control concept opens up before the driver. It is intuitive, fast and free of distractions – created for the sports car of tomorrow. The filigree driver's display is curved, low-profile and free-standing. The instrument cluster shows five round instruments – they can be recognized as Porsche, but they are displayed virtually in OLED technology, i.e. by organic light-emitting diodes. The round instruments are organized according to the driver-relevant themes of Connected Car, Performance, Drive, Energy and Sport Chrono. The controls are just as innovative. An eye-tracking system detects, via camera, which instrument the driver is viewing. The driver can then activate the menu of the instrument in focus by pushing a button on the steering wheel and navigate in it – which also involves an interplay of eye-tracking and manual activation. But that is not all: the display follows the seat position and body attitude of the driver in what is known as a parallax effect. If the driver sits lower, higher or leans to one side, the 3D display of the round instruments reacts and moves with the driver. This eliminates situations in which the steering wheel blocks the driver's view of certain key information, for instance. All relevant information such as vehicle speed is always within the driver's line of sight.
The Mission E can even portray driving fun: a camera mounted in the rear-view mirror recognizes the driver's good mood and shows it as an emoticon in the round instrument. The fun factor can be saved together with individual information such as the route or speed, and it can be shared with friends via a social media link.
Holographic display with touch-free gesture control
The entire dashboard is chock full of new ideas. Its division into two three-dimensionally structuring layers reinforces the impression of lightness and clarity. The upper layer integrates the driver's display, and between the levels there is a holographic display that extends far into the passenger's side. It shows individually selectable apps, which are stacked in virtual space and arranged by priority with a three-dimensional effect. The driver – or passenger – can use these apps to touch-free control primary functions such as media, navigation, climate control, contacts and vehicle. The desired symbol is activated by gestures that are detected by sensors. A grasping gesture means select, while pulling means control. Moreover, driver or passenger can use a touch display on the centre console to control secondary functions such as detailed information menus.
The concept vehicle can also be configured externally from a tablet via Porsche Car Connect. Using "Over the Air and Remote Services" the driver can essentially change the functional content of the vehicle overnight. A simple update via the integrated high-speed data module is all it takes to implement the travel guide or additional functions for the chassis, engine or infotainment system. The driver can use a smartphone or tablet to start updates conveniently from the Porsche Connect Store. Furthermore, Porsche Connect enables direct contact to a Porsche Centre for remote diagnostics or to schedule appointments. Another function of integrated Remote Services is the digital key, which can be sent via the Porsche Connect Portal. It not only lets the owner open the doors, but also other persons authorized by the owner such as friends or family. After successful authentication, the key can be used within a specific time frame and defined location.
The virtual exterior mirrors are literally eye-catching. The lower corners of the windscreen show the images of the outside cameras that are mounted in the front wings. The benefits: the driver gets a better view of images and the surroundings, and safety information can also be actively displayed there

Audi has taken the wraps off its vision of the perfect electric SUV, the Audi e-tron quattro concept, delivering more than 500 km (310 miles) of range along with autonomous driving. Shown off for the first time at the Frankfurt Motor Show today, the concept previews Audi's production luxury electric SUV currently pencilled in for early 2018, with a slippery but meaty design and a trio of motors.
It's clearly an Audi from the outside, but the 16ft length and 6.3ft width are offset by the 5.1ft height, leaving the e-tron quattro concept looking low and chunky. Electrically-actuated aero elements on the hood, the flanks, and on the rear help control the flow of air, adding up to a mere 0.25 coefficient of drag. That, Audi points out, is a record for the SUV segment, where figures in excess of 0.30 cd are more typical.
The lighting uses Matrix lasers, combined with LED and OLED elements, the latter being shown for the first time at the Frankfurt show, but headed to production according to Audi. Inside, there's seating for four and up to 21.7 cu ft of their luggage. Surrounding them is an updated version of the Virtual Cockpit already in production cars, with various unusually-shaped OLED displays scattered across the dashboard.
Around the digital instruments, for instance, are glass touch displays for controlling the piloted driving, multimedia, and navigation, while more touch panels are wrapped around the spokes of the steering wheel. Two more OLEDs are on the center tunnel, while the doors have curved screens that replace external mirrors. In the rear, passengers get their own OLED screens to control the AC and choose what they want to watch on the LTE-streaming media system.
Of course, the real magic is in the powertrain. Audi has equipped the e-tron quattro concept with three motors in all, one at the front axel and two at the rear; altogether, they're good for 400 HP and 800 Nm of torque in boost mode. 0-100 km/h comes in 4.6 seconds, and the top speed is limited to 130.5 mph. The SUV automatically adjusts which rear wheel gets the torque according to grip and stability, while there are various degrees of driver-selectable power recuperation during braking.
Audi has slung the 95 kWh battery under the passenger compartment, keeping the center of gravity low, and paired it with a Combined Charging System (CCS) that's happy with either DC or AC current. Supply the concept with 150 kW of DC power, for instance, and a full charge can be completed in around 50 minutes, the company claims. However, if plugging in a cable is too much for you, Audi Wireless Charging is also included, using contactless induction charging and a low-speed autonomous driving system that navigates the SUV on top of the inductive plate. Finally there's a solar panel on the roof.
All-wheel steering, air suspension, and a combination of radar, video, ultrasonic sensors, and a laser scanner - which feed into what Audi calls the "central driver assistance controller" (zFAS) in the trunk, and which will eventually be used for piloted driving - round out the key tech. Of course, the e-tron quattro concept won't make it to dealerships in quite this form - expect the interior to be significantly more mainstream, for instance - but as EV drivetrains go this one is shaping up to be very interesting, and could cause some consternation over at Tesla's Model X lab.
Audi has taken the wraps off its vision of the perfect electric SUV, the Audi e-tron quattro concept, delivering more than 500 km (310 miles) of range along with autonomous driving. Shown off for the first time at the Frankfurt Motor Show today, the concept previews Audi's production luxury electric SUV currently pencilled in for early 2018, with a slippery but meaty design and a trio of motors.
It's clearly an Audi from the outside, but the 16ft length and 6.3ft width are offset by the 5.1ft height, leaving the e-tron quattro concept looking low and chunky. Electrically-actuated aero elements on the hood, the flanks, and on the rear help control the flow of air, adding up to a mere 0.25 coefficient of drag. That, Audi points out, is a record for the SUV segment, where figures in excess of 0.30 cd are more typical.
The lighting uses Matrix lasers, combined with LED and OLED elements, the latter being shown for the first time at the Frankfurt show, but headed to production according to Audi. Inside, there's seating for four and up to 21.7 cu ft of their luggage. Surrounding them is an updated version of the Virtual Cockpit already in production cars, with various unusually-shaped OLED displays scattered across the dashboard.
Around the digital instruments, for instance, are glass touch displays for controlling the piloted driving, multimedia, and navigation, while more touch panels are wrapped around the spokes of the steering wheel. Two more OLEDs are on the center tunnel, while the doors have curved screens that replace external mirrors. In the rear, passengers get their own OLED screens to control the AC and choose what they want to watch on the LTE-streaming media system.
Of course, the real magic is in the powertrain. Audi has equipped the e-tron quattro concept with three motors in all, one at the front axel and two at the rear; altogether, they're good for 400 HP and 800 Nm of torque in boost mode. 0-100 km/h comes in 4.6 seconds, and the top speed is limited to 130.5 mph. The SUV automatically adjusts which rear wheel gets the torque according to grip and stability, while there are various degrees of driver-selectable power recuperation during braking.
Audi has slung the 95 kWh battery under the passenger compartment, keeping the center of gravity low, and paired it with a Combined Charging System (CCS) that's happy with either DC or AC current. Supply the concept with 150 kW of DC power, for instance, and a full charge can be completed in around 50 minutes, the company claims. However, if plugging in a cable is too much for you, Audi Wireless Charging is also included, using contactless induction charging and a low-speed autonomous driving system that navigates the SUV on top of the inductive plate. Finally there's a solar panel on the roof.

The conceptual basis for a completely new all-electric Audi SUV with a potential range of more than 310 miles will be one of the stars of the IAA in Frankfurt next month. The Audi e-tron quattro concept profits from the expertise gained in the development of the forthcoming R8 e-tron, and the roadgoing model which it will help to spawn will be notable as the brand’s first large-series electric car when it enters production in 2018.
The Audi e-tron quattro concept is designed from the ground up as an electric car and proves to be pioneering in its segment at the very first glance. It follows the Audi “Aerosthetics” concept, combining technical measures for reducing aerodynamic drag with creative design solutions. Movable aerodynamic elements at the front, on the sides and at the rear improve the air flow around the car. The aerodynamically optimised underbody is completely closed. With a cd value of 0.25, the car sets a new record in the SUV segment. This contributes considerably to the long range of more than 500 kilometres (310 miles).
The study is based on the second-generation modular longitudinal platform, which provides considerable scope for the drive system and package. Its length is between that of the Audi Q5 and the Q7. Its typical SUV body and flat, coupé-like cabin give the Audi e-tron quattro concept a very dynamic appearance. The spacious interior offers room for four people.
The large lithium-ion battery is positioned between the axles and below the passenger compartment. This installation position provides for a low centre of gravity and a balanced axle load distribution, giving the car better driving dynamics and driving safety than other vehicles in the segment.
Audi uses its experience with the electrically driven Audi R8 e-tron sports car for the drive system. Three electric motors – one on the front axle and two on the rear – effectively create an ‘electrified quattro’, making the e-tron quattro concept both highly efficient and responsive.
Images of Audi’s all-new Q6 have been leaked online months before its reveal at this September’s Frankfurt motor show.
The renderings, said to be official, first appeared late last night on German website Auto Motor und Sport and are thought to be final drawings of the concept, codenamed C-BEV, that will preview the zero-emission Q6 e-tron.
On sale some time in 2018, it’s already been confirmed by senior Audi board member Dr Ulrich Hackenberg, the Q6 will ride on the Q7’s MLB evo platform and that the objective for engineers was that it must cover 500km between charges.
Back then, Hackenberg said the Q6 must be “a technical light tower” and incorporate state-of-the-art technology.
According to reports from sources close to Audi the C-BEV will lift its motor and the 92kWh batteries from the latest R8 e-tron supercar, but instead of two rear-mounted motors, the Q6 will benefit from an additional third motor encased within its gearbox.
With the third motor the production Q6 e-tron will generate even more power, and the concept is expected to have a combined total of 375kW/700Nm. Factor in widespread use of lightweight composites like carbon-fibre and the new Tesla rival is expected to hit 100km/h in less than four seconds and top out at a limited 250km/h.
As well as a state-of-the-art powertrain the next-generation Q6 e-tron is expected to have a fully autonomous driving feature to allow occupants to enjoy the big Audi’s next-generation infotainment system.
Following the launch of the all-electric version, other more conventional variants powered by internal combustion engines will join the Q6 range. All engines will be borrowed from the Q7 range.
Audi is expected to reveal more of what will star on the 2018 Q6 e-tron production car at the Frankfurt show in September.
Scientists in South Korea have developed a graphene supercapacitor that stores as much energy per kilogram as a lithium-ion battery and can be recharged in under four minutes.
Supercapacitors are not a new idea. But graphene, which is a form of carbon composed of sheets a single atom thick, is especially suitable for making them.
Graphene has an area of 2,675 square metres per gram. All of this surface is available for the storage of static electricity. Graphene could therefore be used to make supercapacitors that hold more energy per kilogram than lithium-ion batteries.
Graphene is to graphite what a single playing card is to a full pack. Strong chemical bonds keep the graphene layers intact, but the individual layers are held to each other only weakly, which is why graphite can be used to make the “lead” in pencils. To make small amounts of graphene, you can peel the layers from the surface of a graphite crystal one at a time, as a dealer might when distributing cards (there are various ways of doing this). To make a lot of it, though, you have to pull the whole crystal apart, as one might scatter a pack across a table.
Dr Lu Wu of Gwangju Institute of Science and Technology, in South Korea, did this in two stages. First, he exposed powdered graphite to oxygen in a controlled manner to produce a substance called graphite oxide. This is not a true oxide, with a fixed chemical formula. Rather, it is a graphite-like substance that has oxygen-rich clusters of atoms between the graphene layers.
This done, he then heated the graphite oxide to 160°C in a vessel which had an internal pressure of a tenth of an atmosphere. The heat caused chemical reactions inside the graphite oxide, and these produced carbon dioxide and steam. The increased internal pressure these gases created, pushing against the reduced external pressure in the vessel, blew the graphite apart into its constituent sheets. Those, after a bit of further treatment to remove surplus oxygen, were then suitable for incorporation into a supercapacitor—which Dr Lu did.
The result, though small, worked well. It stored as much energy per kilogram as a lithium-ion battery and could be recharged in under four minutes. Scaled up to the size needed for a car, the current required to recharge it that quickly would require a pretty robust delivery system.
