700 hp Audi Sport e-tron quattro plug-in hybrid to début @ 2014 CES

Dynamic design, immense power and new electronic features: Audi is presenting a fascinating technology concept car at the Consumer Electronics Show (CES) from January 6 to 10, 2014 in Las Vegas, USA. The Audi Sport quattro laserlight concept is reminiscent of the classic Sport quattro of 1983 while pointing towards the future – with the latest of the brand's technologies in plug-in hybrid drives, user control and display interfaces and lighting technology.

“The new show car demonstrates technical ‘Vorsprung’ on many levels,” says Prof. Dr. Ulrich Hackenberg. “On-board this car we have e-tron technology with 515 kW of power and 2.5 l/100 km (94.09 US mpg) fuel economy; laser headlights that leave all previous systems in the dark with its higher performance as well as new display and operating systems with cutting-edge electronic performance. We are showing the future of Audi here.”

The coupe, a new evolutionary stage of the Sport quattro concept, painted in the color Plasma Red, combines the power of the historic Sport quattro with emotional elegance. Its body is tautly set over its large wheels. The overhangs are short, and the car's proportions show a sporty balance. With a wheelbase of 2,784 mm (109.61 in), it is 4,602 mm (181.18 in) long. At a width of 1,964 mm (77.32 in), the two-door model is very wide, and it is just 1,386 mm (54.57 in) tall, which is exceptionally low.

In the dual headlights, a typical quattro feature, Audi is demonstrating the future of lighting technology by combining matrix LED and laser light technologies. Two low-profile trapezoidal elements are visible within the headlights – the outer one generates the low beam light using matrix LEDs and an aperture mask, while the inner element produces laser light for high-beam functionality.

The powerful laser diodes are significantly smaller than LED diodes; they are only a few microns in diameter. Illuminating the road for a distance of nearly 500 meters (1,640 ft), the laser high-beam light has approximately twice the lighting range and three times the luminosity of LED high beam lights. In this future technology, Audi is once again demonstrating its leadership role in automotive lighting technology with a system that will also be used on the race track in the 2014 R18 e-tron quattro.

The angular, swept-back C pillars of the Audi Sport quattro laserlight concept car and the blisters above the fenders are other design elements reminiscent of the classic Sport quattro. The broad shoulders of the body were reinterpreted and intensively sculpted to convey even greater dynamism. Throughout the car, sharp contours frame muscular surfaces – the interplay between convex and concave curvatures defines the athletic character of the coupe.

The hexagonal single-frame grille also offers an outlook on future design of the sporty production models. The lower section is nearly vertical, while the upper follows the contour of the hood; the screen insert is a typical solution from car racing. The low grille emphasizes the show car's width. Two large, vertical blades divide each of the large air inlets; their form is repeated in the creases of the hood. The splitter, which is made of carbon fiber reinforced polymer (CFRP), is shifted far to the front, as on a race car.

The combination of a swept-back glass cabin and broad shoulders defines the proportions at the rear. Another defining element at the rear of the show car is the CFRP diffuser, which extends upward significantly. Its upper section is honeycombed, while its lower section houses two large, oval tailpipes. The tail lights, which are backed by a black CFRP panel, are rectangular in form – another quattro reference. The luggage space, which is reinforced by a large cross bar stiffener, offers 300 liters (10.59 cu ft) of cargo capacity.

Precise design details round out the dynamic look of the Audi Sport quattro laserlight concept. The sill extensions are made of CFRP, the door handles electrically extend from the door when they detect the approach of a hand. The center locking wheels have a five twin-spoke design.

Lightweight design made visible: the interior

In its generously cut interior, the elegant sporty styling of the show car is continued with dark gray colors and clean lines. The interior design and material selections demonstrate the Audi philosophy of lightweight design. The slender instrument panel is reminiscent of the wing of a sailplane. The supporting structure of the interior is a carbon shell that also serves as a storage compartment in the doors.

A line of trim beneath the windshield wraps around the driver and front passenger and integrates functions such as the inside door handles. The folding race car shell seats with their high lateral supports and integrated head restraints, together with the two rear seats, provide space for four persons. The climate controls are integrated in the air nozzles; a single element is used to control the intensity, temperature and volume of the air stream. In addition to showing climate control settings, the slim display at the centers of the air nozzles also shows media data.

New solutions: displays and controls

The interior of the Audi Sport quattro laserlight concept focuses very much on the driver. Even the multifunction sport steering wheel points the way towards future sporty production solutions. It has two buttons which the driver can use to control the hybrid drive, a red start-stop button, a button for the Audi drive select vehicle handling system and a "View" button to control the Audi virtual cockpit.

All key information is shown on the large Audi TFT display in high-resolution, three-dimensional graphics; a cutting-edge Tegra 30 processor from Audi partner Nvidia processes the graphics. The driver can switch between different modes. For example, in the MMI mode the dominant display elements include the navigation map and media lists, while in the Classic view the speedometer appears in the foreground.

Nearly all functions of the Audi Sport quattro laserlight concept can be controlled from the further developed MMI terminal that is mounted on the center console over the tunnel. Its large rotary pushbutton, which also serves as a touchpad, can be pushed in four directions, and it is surrounded on three sides by four buttons – for the main menu, submenus, options and a back function.

The new user interface has a menu structure whose intuitive layout is similar to that of a smart phone. All frequently used functions can be accessed lightning fast. For most inputs, just a few steps are needed thanks to a new free text search feature; generally just four characters suffice for a navigation address. The driver can quickly scroll through lists or zoom the map image using multitouch gestures on the touchpad. Voice control functionality has also been intensively further developed.

Powerful and highly efficient: the drive system

The plug-in hybrid drive gives the Audi Sport quattro laserlight concept fascinating dynamic performance. Its system output is 515 kW (700 hp), and its system torque is 800 Nm (590.05 lb-ft). Power flows via a modified eight-speed tiptronic to the quattro drivetrain, which features a sport differential at the rear axle. The show car's combined fuel consumption, based on the applicable fuel economy standard, is just 2.5 liters of fuel per 100 km (94.09 US mpg) – which equates to CO2 emissions of 59 g/km (94.95 g/mile).

The combustion engine is a four-liter V8 with biturbo charging; it produces 412 kW (560 hp) of power and 700 Nm (516.29 lb-ft) of torque. The cylinder on demand (COD) system, which deactivates four cylinders under part load and a start-stop system make the sonorous eight-cylinder engine very efficient. Located between the 4.0 TFSI and the transmission is a disc-shaped electric motor that produces 110 kW and 400 Nm (295.02 lb-ft). It draws its drive energy from a lithium-ion battery at the rear, which stores 14.1 kWh of energy – enough for up to 50 km (31.07 miles) of all-electric driving. An Audi wallbox that is used for charging provides for optimal energy transfer.

An intelligent management system controls the interplay of engine and motor on demand. The driver can switch between three different modes. In EV mode, just the electric motor operates; its high torque propels the show car with plenty of power – even outside of the city. The active accelerator pedal indicates the transition to Hybrid mode to the driver – by a change in pedal resistance; this is done so that the driver can intentionally influence the mode selection.

The Hybrid mode aims at optimal fuel-savings in the interplay between the TFSI and the electric motor, and environmental and route data are utilized here. The driver can choose the Hold and Charge modes in the MMI to influence the operating strategy, e.g. if the driver wants to ensure that sufficient electrical energy is available for the final kilometers to the destination. The Audi drive select dynamic vehicle handling system offers even more control options – individual driving profiles are set up for different levels of regenerative braking.

In Sport mode, the operating strategy configures the drive system for maximum power. When the V8 and electric motor are boosting, the Audi Sport quattro laserlight concept accelerates from a standstill to 100 km/h (62.14 mph) in 3.7 seconds and can reach a top speed of 305 km/h (189.52 mph).

Body and chassis

A lightweight design strategy also plays a major role in the car's dynamic performance. A combination of ultra high-strength steel sheet and structural elements of cast aluminum is used in the occupant cell. The doors and fenders are made of aluminum, and the roof, engine hood and rear hatch are made of CFRP. This results in an unladen weight of just 1,850 kilograms (4,078.55 lb), including the large battery pack.

The front suspension is comprised of five links per wheel, while the rear suspension is based on the self-tracking trapezoidal link principle of Audi, which guarantees dynamic performance and stability. Stiff tuning of the springs and shock absorbers make the Audi Sport quattro laserlight concept hold tightly to the road, while Audi drive select makes the driving experience even more multifaceted. The dynamic steering system varies the steering ratio as a function of driving speed. The brake calipers grip large, carbon fiber-ceramic brake discs, and the tire size is 285/30 R 21.

U.S. EIA sees only 1.5% Hybrid sales growth to 2040

The U.S. Energy Information Agency seems to have totally sold out to the oil lobby.

The agency predicts, in a report released Tuesday 17th December, that 78 percent of all cars and trucks will still run on gasoline in 2040, down from 82 percent last year. It predicts a big upswing in micro-hybrids and other advanced fuel technologies to 42 percent of all vehicles by 2040.

EIA predicts full hybrids will account for only 5 percent of vehicles in 2040 — up from 3.32 percent today. That's an increase of just 1.7% in hybrid sales over the next 26 years?

It predicts just 1 percent of total sales will be plug-in hybrids and 1 percent full electric vehicles in 2040.

The agency also predicts that when adjusted for inflation, the price of gasoline will rise to $3.90 by 2040, compared to a prior forecast of $4.40.

Even using figures from 2011, at a local level, hybrid sales already far surpass this decades out prediction. In the San Francisco Bay Area 8.4% of all new cars sold were hybrid, Seattle and L.A. 5.7%, San Diego 5.6% and Portland 5.4%.

Lets not even mention Norway where full electric vehicles account for 12% market share amongst passenger car sales or The Netherlands where a plug-in hybrid was the top selling car last month, selling almost twice as many as the best selling petrol car.

Netherlands: Mitsubishi Outlander PHEV #1 top seller on debut

Retail sales of Mitsubishi's Outlander plug-in hybrid (PHEV) only commenced on 21 October in the Netherlands and it has immediately become the best selling car by a significant margin.

2,736 plug-in Outlanders were sold in November (from a total of 2,766 Outlanders) accounting for a market share of 6.8%. The second highest selling car in the Netherlands for November was the Renault Mégane with 1,505.

In EU guise the permanent electric 'Twin Motor 4WD' has a claimed maximum driving range of 824 km, electric only range of 52km, fuel consumption of 1.9l/100km, CO2 emissions of 44 g/km and a maximum speed of 170 km/h. Braked towing capacity is 1,500kg.

The battery pack takes five hours to recharge using a standard European 230V/10A domestic supply but just 30 minutes (to 80%) using a quick charger to CHAdeMO standard.

MMC insists the Outlander PHEV is neither "a mere adaptation of an existing internal combustion engine vehicle nor a dedicated plug-in hybrid EV system high tech showcase" but a further variant of the Outlander – alongside standard petrol and diesel versions "and developed as such from the start of the programme: a unique/no-compromise proposal in the industry and "the first self-power generating twin motor (permanent) 4WD PHEV".

Mitsubishi said dealers had booked 10,000 signed orders across the continent since December 2012 and was "Much expected by dealers and customers in a region forecast to be its largest global market". The automaker expects EVs, hybrids and PHEVs to account for 20% of its production by 2020.

Ford Reveals Automated Fusion Hybrid Research Vehicle

Taking the next step in its Blueprint for Mobility, Ford today – in conjunction with the University of Michigan and State Farm® – revealed a Ford Fusion Hybrid automated research vehicle that will be used to make progress on future automated driving and other advanced technologies.

The result of an ongoing project that builds on more than a decade of Ford's automated driving research, the Fusion Hybrid automated vehicle will test current and future sensing systems and driver-assist technologies. Ford's goal is to advance development of new technologies with its supplier partners so these features can be applied to the company's next generation of vehicles.

"The Ford Fusion Hybrid automated vehicle represents a vital step toward our vision for the future of mobility," said Ford Executive Chairman Bill Ford. "We see a future of connected cars that communicate with each other and the world around them to make driving safer, ease traffic congestion and sustain the environment. By doing this, Ford is set to have an even greater impact in our next 100 years than we did in our first 100."

Today's Ford vehicles already have technology that enables them to park themselves, understand a driver's voice commands, detect dangerous driving situations and assist with emergency braking. With these technologies and others that one day could allow a person to be driven to a destination, the driver always will need to be in control of the wheel if necessary.

"In the future, automated driving may well help us improve driver safety and manage issues such as traffic congestion and global gridlock, yet there are still many questions that need to be answered and explored to make it a long-term reality," said Raj Nair, group vice president, Ford global product development. "With the automated Ford Fusion Hybrid research project, our goal is to test the limits of full automation and determine the appropriate levels for near- and mid-term deployment."

The automated Fusion Hybrid will serve as the research platform to develop potential solutions for these longer-term societal, legislative and technological issues raised by a future of fully automated vehicles.

The Fusion Hybrid research vehicle builds on driver-in-control studies conducted in Ford's VIRTTEX driving simulator. Using VIRTTEX, Ford researchers study how to merge the capabilities of human and automated drivers to create a seamless, integrated experience.

Ford's Blueprint for Mobility
Last year at the Mobile World Congress in Barcelona, Bill Ford outlined Ford Motor Company's Blueprint for Mobility – a plan that describes what the automaker believes transportation will look like in 2025 and beyond, and the technologies, business models and partnerships needed to get there.

Today, Ford is working on improving technology already used in vehicles on the road. This includes functions that alert drivers to traffic jams and accidents, and technologies for parking and for driving in slow-moving traffic.

In the mid-term, vehicle-to-vehicle communications will begin to enter into the mainstream. This will include some autopilot capabilities, such as vehicle "platooning," where vehicles traveling in the same direction sync up their movements to create denser driving patterns.

In the longer-term, vehicles will have fully autonomous navigation and parking. They will communicate with each other and the world around them, and become one element of a fully integrated transportation ecosystem. Personal vehicle ownership also will change as new business models develop. The benefits include improved safety, reduced traffic congestion and the ability to achieve major environmental improvements.

Tomorrow's technology, today
The Ford Fusion Hybrid was chosen as the test platform for the new research effort because it is among the leaders in offering the most advanced driver-assist technologies in its class.

These technologies include Blind Spot Information System, active park assist, lane-departure warning, and adaptive cruise control and collision warning with brake support. These vehicle sensing systems, offered on many Ford vehicles today, are the building blocks for the future of fully automated driving.

In North America, these technologies can be found on Ford Focus, C-MAX hybrids, Fusion, Taurus, Escape, Explorer and Flex. In Europe, these technologies are available on Ford C-MAX, Mondeo, S-MAX and Galaxy.

"Products such as Ford Fusion Hybrid give us a head start in the development of automated features," said Paul Mascarenas, chief technical officer and vice president, Ford research and innovation. "Our Blueprint for Mobility aligns the desired outcomes of our work in automated functionality with the democratization of driver-assist technology found on today's lineup of Ford products."

Ford's Fusion Hybrid research vehicle is unique in that it first uses the same technology found in Ford vehicles in dealer showrooms today, then adds four scanning infrared light sensors – named LiDAR (for Light Detection And Ranging) – that scan the road at 2.5 million times per second. LiDAR uses light in the same way a bat or dolphin uses sound waves, and can bounce infrared light off everything within 200 feet to generate a real-time 3D map of the surrounding environment.

The sensors can track anything dense enough to redirect light – whether stationary objects, or moving objects such as vehicles, pedestrians and bicyclists. The sensors are so sensitive they can sense the difference between a paper bag and a small animal at nearly a football field away.

Working together
Developing the necessary infrastructure to support a sustainable transportation ecosystem will require the collaboration of many partners across multiple industries. State Farm and the University of Michigan's robotics and automation research team are critical to creating the visionary research project.

Ford's work with others on the future of mobility is longstanding. Ford was an active participant in the Defense Advanced Research Projects Agency (DARPA)-controlled autonomous vehicle challenges in 2004, 2005 and 2007, the year Ford extended its efforts to include the University of Michigan.

While Ford is responsible for developing unique components allowing for the vehicle to function at high levels of automation, the University of Michigan – under the direction of faculty members Ryan Eustice and Edwin Olson – is leading in development of sensor-based technologies. The sensors aid in the logic and virtual decision making necessary to help the vehicle understand its physical surroundings on the road.

The university's researchers are processing the trillions of bytes of data collected by the vehicle's sensors, from which they can build a 3D model of the environment around the vehicle. The goal is to help the vehicle – and the driver – make appropriate and safe driving decisions.

"This research builds on the University of Michigan's long history of pioneering automotive research with Ford," said Alec Gallimore, associate dean of research and graduate education at the school's College of Engineering. "The unique collaboration will enable Ford to benefit from the university's deep knowledge of robotics and automation, and it will allow University of Michigan faculty and students to work side-by-side with some of the best auto engineers in the world."

Meanwhile, State Farm has been working with Ford to assess the impact of driver-assist technologies to determine if the technologies can lower the rate of rear collisions.

Last year there were nearly 34,000 fatalities due to traffic accidents in the United States. By developing more intelligent vehicles, Ford helps create smarter drivers.

"By teaming up with Ford and the University of Michigan in this research, we are continuing our decades-long commitment to making vehicles, roadways and drivers safer," said State Farm Chairman and CEO Edward Rust. "The changes new technologies bring to our lives are exciting, and we are always looking at how technology can better meet the ever-changing needs of our customers."

Setting the stage for mobility in Michigan
Today's Ford Fusion Hybrid research vehicle announcement follows an aggressive plan released this week by Business Leaders for Michigan to position the state as the global center for mobility and grow up to 100,000 new jobs in its auto sector by becoming a hub for excellence in advanced powertrain, lightweight and smart/connected transportation technologies.

With Bill Ford as champion of Business Leaders for Michigan's mobility initiative, the plan has been developed with a coalition of top industry experts, the Center for Automotive Research and McKinsey & Company. The plan identifies growth strategies for the auto sector as it transitions to an increasingly advanced technology-based sector.

Porsche LMP1 Hybrid to use 4-Cyl Petrol Engine with dual regen systems

Porsche has concluded its 2013 test programme with the new LMP1 race car. The Porsche LMP1 completed its final test laps of the year on the Autódromo Internacional do Algarve near Portimão, Portugal. Testing will resume in early 2014. Porsche AG will field two LMP1 race cars in the sports car World Endurance Championship (WEC) which starts in April 2014, with the Le Mans 24 Hours as the highlight of the season.

The WEC regulations stipulate that manufacturers run hybrid vehicles in the highest class for Le Mans Prototypes (LMP1). In developing the all-new LMP1 race car featuring a very efficient, high-performance hybrid drive, Porsche's engineers are faced with major challenges that can only be solved using innovative solutions. Therefore, the race car features a hybrid system that consists of a four-cylinder petrol engine with direct injection and two energy recuperation systems. The recovered energy is stored in a battery until retrieved by the driver. A powerful electric motor then provides additional drive to the front axle. However, the WEC rules limit the amount of fuel as well as the electrical energy, or so-called boost, available to the driver per lap. The development of such a highly-efficient drive will have positive influences on production development at Porsche.

On the Autódromo Internacional do Algarve, Mark Webber (37) got his first chance to climb aboard the Porsche LMP1 racer. The Red Bull Racing Formula 1 team gave the Australian the green light to conduct these initial tests, despite Webber still being under contract. From 1 January 2014, Mark Webber officially joins the Porsche factory team as a works driver and reinforces the already-signed driver line-up of Timo Bernhard (32), Romain Dumas (35) and Neel Jani (30). Mark Webber commented in Portimão: "My first day in this fascinating project was an intense experience for me. I would like to thank Red Bull Racing for giving me the chance to join the project so early. This is a major and important step for us all. It allows me to integrate with the team quicker and to contribute to further developing the LMP1 race car. We have a long way to go and it involves a lot of hard work. I have no misconceptions about this." Head of Porsche LMP1 Fritz Enzinger also appreciated the goodwill shown by the Austrian F1 team: "I'm delighted to have Mark in the team so early. Red Bull Racing has helped us considerably in allowing this!"

On the schedule of the final test for 2013 in Portugal were primarily suspension and tyre tests with partner Michelin. Previously, the Porsche LMP1 squad had pressed ahead with the development of the new race car on the Magny-Cours (France), Monza (Italy) and Paul Ricard (France) circuits, as well as on the Eurospeedway Lausitz (Germany). Enzinger stated: "Between the roll-out of the completely new car in June and now we have made significant progress. Every single kilometre was important, providing us with new data that brought the development forward. The whole team has worked extremely hard and I would like to express my sincere thanks for this. Our efforts will continue unabated in 2014. Until the start of the season at Silverstone mid-April there is still a lot to do."

Wolfgang Hatz, Member of the Executive Board for Research and Development at Porsche AG, added, "We always knew it wasn't going to be easy to return to top endurance racing after 16 years. Hence, our efforts in developing a competitive Porsche LMP1 race car are immense. Up to this point, our engineers in Weissach, the drivers, and the entire team have performed impressively. We are finding new approaches in the development, implementation and application of leading edge efficiency technologies. This also leads to further improvements of the entire hybrid technology in our production cars. Ultimately, our customers will benefit the most."

The new technology behind the 2014 Audi R18 e-tron quattro

The 2014-generation Audi R18 e-tron quattro is the most complex race car ever built by Audi. At first glance, the new hybrid sports car appears like a continuous further development of the World Championship winning car and Le Mans winner of the past two years. However, due to the new LMP1 regulations that will come into effect in 2014, Audi Sport factually redeveloped every single component.

“The next Audi R18 e-tron quattro represents a completely new generation of Le Mans prototypes,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich. “The principles of the LMP1 regulations have fundamentally changed. The idea behind this is to achieve similarly fast lap times as in the past with considerably less energy. Making more out of less: a forward-thinking approach.”

Chris Reinke, Head of LMP at Audi Sport, talks about a ‘revolution in thinking.’ “A fundamental approach to motorsport is being abandoned. Instead of power output, energy consumption will be subject to limitations – this is in line with the spirit of our times and opens up great technical freedoms to the engineers. In 2014, we’ll be seeing a wide variety of concepts on the grid at Le Mans.”

The basic elements of the Audi R18 e-tron quattro’s new configuration were defined back in 2012 and the design of all the single components started at the end of 2012. The new LMP1 sports car was rolled out in the early fall of 2013, followed by track tests of the most recent R18.

In the new Technical Regulations, a large number of principal definitions, which concern the powertrain, body dimensions, safety and aerodynamics, were re-determined. With the new R18, Audi Sport has opted for a similar concept as in the past – albeit with innovative detailed solutions and an additional hybrid system. The key details:

  • A further developed V6 TDI mid-engine powers the rear wheels
  • e-tron quattro hybrid system at the front axle (ERS-K – Energy Recovery System Kinetic, a system to store kinetic energy)
  • Optimized flywheel energy storage system
  • Hybrid system with an electric turbocharger in the internal combustion engine (ERS-H – Energy Recovery System Heat, a system that stores energy converted from heat)

    New approaches to powertrain technology and energy management

    Never before has a race car been powered by technology as complex as the one used in Audi’s new LMP1 sports car. The TDI engine, which sets the benchmark in terms of efficiency, remains a time-tested and important element of the overall concept. The further developed V6 TDI unit of the Audi R18 e-tron quattro makes a crucial contribution to the car’s compliance with the energy specifications of the regulations. The new R18 has to do with up to 30 percent less fuel than its immediate predecessor.

    In addition to the internal combustion engine, the powertrain concept, for the first time, features the integration of two hybrid systems. As in the past, a Motor-Generator-Unit (MGU), during braking events, recovers kinetic energy at the front axle, which flows into a flywheel energy storage system. For the first time, the turbocharger of the internal combustion engine is linked to an electrical machine, which makes it possible to convert the thermal energy of the exhaust gas flow into electric energy – for instance when the boost pressure limit has been reached. This energy also flows into the flywheel energy storage system. When the car accelerates, the stored energy can either flow back to the MGU at the front axle or to the innovative electric turbocharger, depending on the operating strategy.

    The overall design of these systems and their direct impact on engine and powertrain management require highly complex coordination and tuning work. Audi Sport initially performed theoretical analyses and simulations, followed by rig testing and, since October, by track tests. The options available to the drivers and engineers as a result of the new technology are now more extensive than ever before.

    Significantly changed conditions for the aerodynamicists

    New freedoms, accompanied by greater restrictions – this is how the new framework conditions for aerodynamics can be put in a nutshell. A few examples: The 10 centimeter slimmer body of the new LMP1 sports car means that the front of the R18 becomes mathematically smaller – which is an advantage. The bodywork accommodates slimmer wheels, which, in turn, reduces aerodynamic drag. This is contrasted by other innovations that do not provide any advantages in aerodynamics. At 1,050 millimeters, the race car has to be 20 millimeters higher than before, and larger cockpit dimensions are prescribed as well. This leads to less favorable aerodynamics. The lower overall width of the car results in a slimmer underfloor. In addition, it features a completely different shape in the area of the cutouts for the front wheels. Consequently, the area that can produce downforce becomes smaller. With respect to designing the front end, the engineers enjoy new freedoms. Instead of a diffusor, a genuine front wing with a flap may be used for the first time. This promises aerodynamic advantages and lower costs, as this part of the bodywork will lend itself to easier modification to suit the various race tracks. In the past, it was necessary to produce different bodywork assemblies.

    On the other hand, greater limits have been imposed on the aerodynamic design freedoms at the rear end. Use of the exhaust gas in the area of the rear diffusor, as in the case of the 2013-generation Audi R18 e-tron quattro, is now prohibited.

    Further improvement of safety

    Even in the past, LMP1 sports cars with their closed CFRP cockpit structure were regarded as one of the safest race car categories of all. Two severe accidents of the R18 at Le Mans in 2011 saw the Audi drivers get off lightly. But this is no reason to stop. The rule-makers have continued to improve the safety of the latest race car generation by imposing numerous discrete requirements.

    The new monocoque has to resist higher loads. At the same time, it is reinforced by additional layers of fabric, which are hard to penetrate in the case of a concentrated impact. This reduces the risk of intrusion by pointed objects in accidents.

    For the first time, wheel tethers are prescribed. They connect the outer assemblies of the front wheel suspensions with the monocoque and the ones of the rear suspensions with the chassis structure. Each of the two tethers required per wheel can withstand forces of 90 KN – which equates to a weight force of nine metric tons. Another new feature is a CFRP structure behind the transmission – the so-called ‘crasher’ – which absorbs energy in a collision.

    This is another example of the considerable challenges faced by the Audi engineers, as all these innovations increase weight, in addition to the second hybrid system. Audi’s previous Le Mans prototype weighed 915 kilograms. But in the future the car’s weight may be reduced to 870 kilograms – which means that Audi’s ultra-lightweight design technology reaches a new dimension.

    A large number of further innovations – for instance in the areas of vision and interior ergonomics – characterize the new Audi R18 e-tron quattro that will be making its racing debut in the 6-hour race at Silverstone (Great Britain) on April 20, 2014. The highlight of the FIA World Endurance Championship (WEC) will be the Le Mans 24 Hours on June 14/15, 2014. The aim is clear: Audi is setting its sights on continuing to maintain the leading role it has enjoyed in sports prototype racing since 2000 and on again demonstrating ‘Vorsprung durch Technik’ at Le Mans.

    Next Gen Lancer Evolution Hybrid to get different name

    This makes sense. Because the next generation Mitsubishi Lancer Evolution performance car is so different from the Evolution models that came before it, the Japanese automaker could assign it a completely different name, according to Motor Trend.

    While the next-gen car will still reportedly be turbocharged and all-wheel-drive, the engine will be downsized to a tuned version of the brand's 1.1-liter three-cylinder engine and will use electric motors on both front and rear axles similar to the Outlander PHEV's setup.

    Sources are hinting that those motors combined with Mitsubishi's next-gen S-AWC would give the Evo replacement handling capabilities beyond any past model.
