'Power like a big V6, fuel economy like a modest four-cylinder unit' this is how Audi describes its A8 Hybrid Concept unveiled today at the Geneva Motor Show. As we told you earlier, before the official debut, the car comes with the same 2.0 TFSI engine found also on the Golf GTI and capable to deliver 211 hp (155 kW) and 350 Nm (258.15 lb-ft) of torque from 1,500 to 4,200 rpm.
A hydraulically operated wet clutch links the 2.0 TFSI with the electric motor. The synchronous motor, which is continually excited, also serves as a generator that develops 33 kW (45 hp) of power and 211 Nm (155.63 lb-ft) of torque. With these numbers the Audi A8 Hybrid can sprint from 0 to 100 km/h in just 7.6 seconds and has a top speed of 235 km/h (146.02 mph).
All of these with an impressive fuel consumption of just 6.2 liters (37.94 US mpg) per 100 km and CO2 emissions of 144 grams per km (231.75 g/mile). In city traffic, the hybrid drive uses about 20 percent less fuel than a conventional drive. The engine is mated to a eight-speed tiptronic gearbox while the propulsive power of both drive systems is applied to the road through the front wheels.
The Audi A8 Hybrid can be driven as a fully electric car with a speed of 65 km/h (40.39 mph) and for a distance exceeding two kilometers. After the speed is above 65 km/h (40.39 mph) the combustion engine alone does all the propulsive work, while the electric motor supplies onboard users and recharges the battery.
Regarding the design of the A8 Hybrid Concept, the car features a Prism Silver with Spectra Flair paint job as well as 21-inch two-colour wheel rims styled with highly three-dimensional surface area. The passengers see the prominent hybrid logo displayed on the dashboard. The "Powermeter" in addition shows the energy flow in the instrument cluster.
