Audi Q7 Hybrid: Concentrated know-how

Audi Q7 Hybrid
We told you yesterday that Audi will bring the Audi Q7 Hybrid in 2008. Here’s everyting you need to know about that car. Can’t wait to drive it!

The concept of the Audi Q7 hybrid is a full hybrid vehicle in parallel configuration – a concept that Audi has been pursuing for many years. This principle, in which all major assemblies are linearly situated, has great benefits compared to a series configuration, such as the concepts used by the competition. There, the complex system of electric motor, separate alternator and planetary gears has drawbacks not only in terms of weight, but also in terms of energy loss. Functions such as “sailing” (coasting without power), which parallel hybrids are able to realise, are not possible with series hybrids. In certain situations the electric motor actually has to build up braking force to regulate the driving current.

Audi’s hybrid drive uses a 3.6 litre FSI V6 with an output of 206 kW (280 bhp) and a peak torque of 375 Nm. An electric motor situated in the drive train adds up to 285 Nm of additional torque. It is a matter of honour for such a supremely powered Audi to be equipped with quattro four-wheel drive, which permanently ensures a maximum of driving dynamics and road safety. Power is transmitted via a six-speed tiptronic gearbox.

The driving performance of the Audi Q7 hybrid is equal to that of a sports car. From standstill, 100 km/h is reached in just 7.6 seconds. And the pulling power is even more impressive. In fifth gear, the large SUV powers its way from 60 to 120 km/h in just 11.9 seconds. In normal driving conditions, the Audi Q7 hybrid, weighing 2,480 kg unladen, consumes on average 9.8 litres of fuel for 100 kilometres. That is 23 percent less than the basic model. The efficiency of the Audi hybrid drive can hardly be demonstrated more convincingly.

Under the bonnet, the 3.6 litre six-cylinder engine is no different from a standard engine. It is equipped with the highly efficient FSI petrol direct injection system. This enables it to develop more output and dynamism than a conventional engine with manifold injection. The V6 is characterised by a beefy torque curve right up to the rated speed, agile response and economical fuel consumption.
