audi-laserlightIlluminating the road ahead is a crucial element in driving. It’s also one that has long benefitted from technological innovation. To this end, Audi celebrates the evolution of automotive lighting with its Sport quattro laserlight concept car. The high performance, two-door, Plasma Red coupe harkens back to the iconic 1983 Sport quattro even as it’s abundant advanced technology and design cues point to the future.

The laserlight concept is named for its future lighting technologies. Two low-profile trapezoidal elements are visible within the headlights. An outer one generates low beam light using matrix LEDs and an aperture mask, while an inner element produces laser light for the high-beam.

Laser diodes are significantly smaller than LED diodes, only a few microns in diameter. They can illuminate the road for a distance of nearly 1,640 feet, approximately twice the lighting range with three times the luminosity of LED high beam lights. This technology is finding use in the 2014 R18 e-tron quattro for track duty.

Motivating the laserlight concept is a 4.0-liter, bi-turbo V-8 TSFI (turbo stratified fuel injection) engine and a disc-shaped electric motor located between the engine and transmission. The V-8 produces 560 horsepower and 516 pound-feet torque, with the electric motor contributing an additional 148 horsepower and 295 pound-feet torque. A modified eight-speed Tiptronic transmission is mated to the quattro drivetrain with a sport differential at the rear axle.

Electrical energy is stored in a 14.1 kilowatt-hour lithium-ion battery, sufficient for 31 miles of all-electric driving. When the V-8 and electric motor are working together, the Audi Sport quattro laserlight concept can accelerates from 0 to 62 mph in 3.7 seconds. Top speed is 189 mph. This impressive performance comes with an equally impressive 94 US mpg fuel economy. This is achieved in part through its electric plug-in operation in addition to a cylinder on demand system that deactivates four cylinders of the V-8 under partial load. Also helping is a start-stop system and several levels of regen braking to enhance driving dynamics.

Drivers can switch between three different modes. In EV mode, just the electric motor operates with sufficient high torque power, even outside the city. The active accelerator pedal indicates the transition by a change in pedal resistance so a driver can intentionally influence the mode selection. The Hybrid mode provides optimal interplay between the V-8 and the electric motor for best fuel-savings, and additionally incorporates environmental and route data. A driver can choose the Hold and Charge modes to ensure sufficient electrical energy is available for electric-only driving at their destination. There are different levels of regenerative braking to enhance the driving experience.

The laserlight’s multifunction sport steering wheel has buttons to control the hybrid drive, start-stop function, vehicle handling system, and the car’s virtual cockpit. Key information is shown on the large Audi TFT display in high-resolution 3D graphics. A cutting-edge Nvidia Tegra 30 processor handles the graphics.

Nearly all functions can be controlled from the further-developed MMI mounted on the center console. Its large rotary pushbutton, which also serves as a touchpad, can be pushed in four directions. It’s surrounded on three sides by four buttons that control the main menu, submenus, options, and a back function. The intuitive layout is similar to a smart phone with all frequently used functions accessed lightning fast.

Lightweight design plays a major role in the Audi laserlight concept’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, with the roof, engine hood, and rear hatch and other components made of carbon fiber reinforced plastic (CFRP). Thus, the concept weighs 4,079 pounds including the weight of the large battery pack.

 

The Mercedes-Benz G-Class, or G-wagen – short for Geländewagen – has been around since 1979. It looks like Mercedes-Benz could be offering this iconic, off-road capable SUV for many more years.

Mercedes-Benz Advanced Design Studio in Carlsbad, California created the Ener-G-Force concept shown at the 2012 L.A. Auto Show, a civilian version of the Mercedes-Benz entry in the 2012 Los Angeles Design Challenge. Mercedes-Benz was one of six entrants that presented their vision of the Highway Patrol Vehicle 2025, this year’s theme.

The futuristic Ener-G-Force is powered by hydrogen fuel cells supplying electricity to four wheel-hub motors that motivate 20-inch wheels. Advanced electronics adapts power output for each individual wheel to provide precisely the right amount of traction required for the respective terrain. A roof-mounted, 360-degree ‘Terra-Scan’ topography scanner provides a handy read on nearby surroundings, with scan results used to adjust the spring and damping rates as well as other suspension parameters for maximum on- and off-road traction.

Recycled water stored in tanks on the Ener-G-Force roof is transferred to an on-board hydro-tech converter, which in turn electrolyzes water into hydrogen for the fuel cells. This renewable energy could provide an estimated zero-emission operating range of about 500 miles.

The vehicle’s strikingly-styled side skirts are designed to house either energy storage units or hot-swappable battery packs. Color changes in the side skirts’ illumination indicate energy pack operating and charge status.

The police version is differentiated with emergency lights integrated into the roof and other law enforcement equipment and markings. Less glass area is also found on the police variant to provide a safer environment cocoon for police officers.
