The next generation Audi Q7 will be available as a diesel plug-in hybrid, which would make the world’s second plug-in hybrid to use a diesel engine after the Volvo V60 Plug-In Hybrid. Audi sources told Automotive News Europe that the diesel plug-in variant would be sold in both Europe and US markets.

The plug-in diesel Q7 would probably use the company’s new 3.0 litre V6 turbodiesel engine. Audi already has a plug-in hybrid, but it uses petrol engines. The Audi A3 Sportback e-tron mates a 1.4 litre TFSI engine to an electric motor and a hybrid e-S tronic transmission.

An 8.8 kWh lithium-ion battery placed ahead of the rear axle can provide full electric drive for up to 50 km with zero emissions. Combined system output is rated at 204 hp and 350 Nm, enabling it to reach 100 km/h in 7.6 seconds and on to a top speed of 222 km/h. Full range with both electric and petrol engine in use is 940 km, with an average fuel consumption of just 1.5L/100 km (ECE standard).

Audi also has plans for e-tron versions of the A6 using a similiar plug-in hybrid powertrain, since the A6 Hybrid has been phased out for the facelift.

Volvo’s V60 Plug-In Hybrid combines a five-cylinder 2.4-litre D5 engine with 215 hp/440 Nm at the front axle with a rear axle that features an ERAD (Electric Rear Axle Drive, an electric motor) with 70 hp/200 Nm. ERAD is powered by a 12 kWh lithium-ion battery pack. The car features a six-speed automatic gearbox. In the EU combined cycle, this car is rated at 53.1 km/l and the range is nearly 1,200 km. Volvo says that fuel cost will be one third of a normal V60.
