An evolution of the sport quattro concept, painted in Plasma Red, this homage to the historical Sport quattro utilizes the same combination of laser light and matrix LED technology seen in Audi’s 2014 R18 e-tron quattro racecar.
Along with the twin trapezoidal LED units, the laser diodes are much smaller than LED diodes – only a few micrometres, but they emit a range in excess of 500 metres. The beam comes about twice as far and three times as bright as LED high beam.
As mentioned, the Sport quattro concept uses a plug-in hybrid drive that makes use of the twin-turbo V8 from the RS 6 Avant, which develops 412 kW (560 hp) and 700 Nm of torque, along with a disc-shaped electric motor. Located between the 4.0 TFSI and the transmission, it produces a peak output of 110 kW and 400 Nm and is fed by a 14.1 kWh liquid-cooled lithium-ion battery in the rear, allowing a range of 50 km (31 miles) on electric power alone.
In Hybrid mode, route data is used to compute the optimal combination of the combustion engine and electric motor for fuel efficiency. However, this mode can also be customized by the driver should they want to retain a certain amount of electric range or to drive certain route segments on electric power, while the Hold or Charge function adjusts the charge of the battery even without charging from the power grid.
In Sport mode, the operating strategy sets the drive system for maximum power and performance. With 515 kW (700 hp) and 800 Nm pumping through a modified eight-speed tiptronic gearbox to the quattro powertrain with sport differential on the rear axle, the Sport quattro concept rockets to 100 km/h in 3.7 seconds before reaching a top speed of 305 km/h (190 mph).
“This show car embodies our development expertise and pioneering electronics shows features such as high-power laser beam headlamps,” said Prof. Dr. Ulrich Hackenberg, Member of the Board of Audi AG.
