Audi Sport quattro laserlight concept unveiled at CES 2014





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 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.

Today TOYOTA GAZOO Racing (TGR) unveiled the GR Super Sport Concept at the 86th edition of the 24 Hours of Le Mans.
First revealed at the 2018 Tokyo Auto Salon in January, this next-generation hyper car incorporates hybrid electric technology honed through Toyota's participation in the FIA World Endurance Championship (WEC).
Meanwhile, the development of Toyota's next generation of super sports car has started. It takes the cutting-edge hybrid electric systems and fuel economy technology that the TGR WEC team has tested and refined during the past six years in WEC, and showcases them in one superb package.
The GR Super Sport Concept is powered by a V6 twin turbocharger and the Toyota Hybrid System-Racing (THS-R), delivering a combined output of 1,000 DIN hp, which it shares with the TS050 Hybrid LMP1 race car.
Shigeki Tomoyama, President of GAZOO Racing Company, said: "Competing in the World Endurance Championship -one of the most deman…
