Perfectly timed for the world famous Bathurst 1000 endurance race this coming weekend at Mt Panorama, the guys at CarAdvice.com have set up the ultimate drag race.
It's the world's fastest four-door sedan, the Tesla Model S P85D, against Australia's fastest four-door sedans, the Supercheap Auto Racing Holden Commodore V8 Supercar and the Walkinshaw Performance W507 HSV GTS.
The Tesla Model S P85D rockets from 0-100km/h in just 3.3-seconds, while the V8 Supercar does it in 3.4-seconds, but weighs just 1400kg with the driver.
ElectriCity is a unique collaboration that has resulted in Gothenburg's first modern electric bus route. Volvo is one of the project partners and was also involved in creating the Silent Bus Sessions, a campaign involving some of Sweden's hottest artists performing four songs for unsuspecting passengers on the silent buses on route 55.
The campaign “Silent Bus Sessions” has become a viral success. The videos, where Swedish artists Zara Larsson and Seinabo Sey perform on the new electric bus route in Gothenburg have reached 2.5 million views.
Here's a behind the scenes look at the set of Silent Bus Sessions.
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.

Siemens will show the wheel motor powered Roding Roadster Electric at the 2015 IAA (Internationale Automobil-Ausstellung) in Frankfurt Germany this month.
The Roding Roadster Electric is a hub drive powered research vehicle. Based on the Roding Carbon Cell, this innovative battery-powered drive train could be realized together with Siemens Corporate Technology. The prototypes used for this purpose were constructed without a mechanical brake at the rear axle, instead, braking is done by the electric motor.
The brake system is controlled by so-called Brake Blending, i.e., as circumstances require, the brake torque is automatically transferred from the electrically powered brake to the friction brake at the front axle. It is aimed to recuperate the entire potential energy in 70% of all braking processes.
Proterra announced today that their 40-foot Catalyst XR bus drove 258 miles (412 km) on a single charge under test conditions at Michelin's esteemed Laurens Proving Grounds (LPG). The Catalyst's range demonstration marks a significant step toward Proterra's goal of providing a high-performance bus that can serve any typical transit route in the United States.
The Catalyst XR configuration included eight battery packs, with a total energy capacity of 257 kWh. Based on these test results, Proterra predicts its ten pack XR configuration (321 kWh) will achieve 300 miles (480 km) on a single charge. According to available General Transit Feed Specification (GTFS) data, typical urban and rural bus routes in the United States run less than 200 miles a day, bringing most routes within reach of Proterra's current technology.
"The purpose-driven Catalyst design affords the best efficiency rating ever for a 40-foot transit bus, at 22 MPG equivalent," said John Sleconich, Chief Engineer at Proterra. "Proterra buses are the only mass transit vehicle built from the ground up as an electric vehicle. With a unique aerodynamic body made from carbon fiber and advanced composite materials, we are able to reduce mass for maximum efficiency."
Beyond meeting a given route's minimum range requirements, Proterra electric vehicles are poised to make a significant impact on the transit market because of the Catalyst's low operational cost per mile compared to diesel, CNG, and diesel-hybrid buses. Over the 12-year life of a bus, Proterra customers will dramatically reduce maintenance costs, saving around $135K. The environmental benefits are also making an impressive impact. Collectively, Proterra customers have logged more than 1.3 million miles of revenue service to date, preventing more than 4.7 million pounds of emissions.
"The U.S. is quickly waking up to the economic, environmental, and performance benefits of zero-emission electric buses," said Proterra CEO, Ryan Popple. "While diesel buses pollute our communities and are increasingly more costly to own and operate, Proterra is pushing the bounds of EV technology and steadily driving down costs. Achieving this range is validation for our technology and gives us the confidence that Proterra is capable of what we initially set out to accomplish - replacing every fossil fuel bus in the United States with a fully electric one. "
Consumer Reports put the performance version of Tesla's all-electric Model S through its testing and found that it's fast and super-efficient, proving that car companies don't have to sacrifice to achieve superior fuel economy.
Polish blogger Marek Wieruszewski reviews the Volkswagen e-Golf and the BMW i3 REx.
The Volkswagen e-Golf has a claimed range of up to 200 kilometres while the BMW i3 can squeeze up to around 160 kilometers, but it can be equipped with a petrol range-extender, which doubles its range.
