According to the latest reports from Automotive News, Audi will introduce a more fuel efficient version of the A8 flagship sedan powered by a four-cylinder gasoline engine. The surprise is that this engine will also be helped by an electric motor, in order to deliver better performance.
This comes after Mercedes-Benz introduced the S 250 CDI, the most fuel efficient version of the S-Class flagship sedan powered by a 2.2-liter four-cylinder CDI engine capable to deliver 204 hp and a maximum torque of 500 Nm.
The S250 CDI delivers impressive performances: 0-100 km/h (62 mph) in just 8.2 seconds and a top speed of 240 km/h (150 mph).
Regarding the A8 Hybrid, it appears that this model will have an advantage, thanks to the electric motor. The car will be powered by a 2.0-liter gasoline engine delivering 211 hp, but the total output of the car will be 245 hp (180 kW) and a torque of 480 Nm (354.03 lb-ft).
This means that the electric motor will help the four-cylinder engine deliver the same performances as a six-cylinder engine.
Comparing it to the S250 CDI, the fuel consumption will be less impressive, because the A8 Hybrid will be capable to deliver only 6.2 l/100 km (37.94 US mpg), equivalent to CO2 emissions of 144 g/km (231.75 g/mile), while the S250 CDI delivers 5.7 liters/100 km (41 mpg) as well as 149g of CO2 emissions. The new Audi A8 Hybrid is expected to hit the market in 2012!
