Audi's A8 Hybrid Delivers Efficient Luxury
GENEVA, SWITZERLAND - At the 2010 Geneva Motor Show, theirEarth took this photo of Audi's A8 Hybrid pre-production car. Audi has given the A8 Hybrid a vehicle performance equivalent to that of V6 powered car, but it uses a 4-cylinder 2.0 TFSI gasoline engine mated to an electric motor to create an efficient hybrid drive arrangement.
The Audi A8's hybrid drive delivers a combined 180 kW (245 hp) of total horsepower. Under full acceleration the A8's electric motor produces 33 kW (45 hp) of peak power, and the 4-cylinder gasoline engine is capable of delivering a maximum of 155 kW (211 hp) of power. Audi says that the A8 Hybrid can accelerate from zero to 100 km/h (62.14 mph) in 7.6 seconds and reach a top speed of 235 km/h (146.02 mph).
Powering the Audi A8's hybrid electric motor is a lithium-ion battery pack that when fully charged can propel the car to an all-electric speed of up to 65 km/h (40.39 mph), and do this for up to two kilometres before the gasoline engine starts. The A8 uses an automatic hybrid drive program that determines the proportion of electric versus gasoline derived power. Audi says the driver can also manually select the electric drive mode by applying the 'e-key'on the console. The A8's Hybrid Drive power delivery is displayed on a graphic screen on the dashboard letting the driver know all about the hybrid drive system's performance.
Audi says that their electric hybrid drive system regenerates the battery whenever the driver initiates a slow-down or braking phase and that the e-motor switches polarity to deliver charging in deceleration events. The A8 Hybrid (as seen in the photo) rides on 21-inch wheels with 265/35 tires on all four wheels. Audi has painted the A8 Hybrid in a colour they call 'Aqua Mint - Pearl Effect' and the colour is also part of the interior door trim and on the driver's console. Audi hasn't yet indicated the release date for the A8 Hybrid, but they are saying it has pre-production model status.
