Audi’s Q7 e-tron’s diesel-electric hybrid system is fairly conventional, but we can never say no to a nice animation detailing the way it works.
It also lists the various components that go into creating it, so if you’re a Chinese automaker looking to make your first hybrid, this is a good place to start – just don’t make it look the same or people will be in on it.
The Q7 relies on a 3.0-liter TDI diesel engine and an electric motor housed within the gearbox. It’s the kind of system used by other manufacturers, but it’s different to what Lexus uses, for instance, as that has a separate motor on the rear axle solely driving the rear wheels – in the Q7 the same electric motor can’t not drive all four wheels.
Packing 368 total horsepower, the system relies on a (fairly big) 17.3 kWh battery pack that is said to offer 56 km or 35 miles of emissions-free driving. The sprint to 100 km/h or 62 mph is handled in six seconds dead and it emits 50 g/km CO2 while using up a claimed average 1.7 l/100km.
