From Audi’s website:
275 kW (373 hp) system output and 700 Nm (516.3 lb-ft) system torque – the Audi Q7 e-tron quattro sets new standards with its plug-in hybrid technology and quattro drive. The large SUV accelerates like a sports car from 0 to 100 km/h (62.1 mph) in 6.0 seconds, but consumes no more than 1.7 liters of fuel per 100 kilometers (138.4 US mpg) in the NEDC cycle – a best value in its class.
The Audi Q7 e-tron quattro is the first plug-in hybrid car in the world to combine a six‑cylinder diesel engine with quattro drive. With a system output of 275 kW (373 hp) and 700 Nm (516.3 lb-ft) system torque, it accelerates from 0 to 100 km/h (62.1 mph) in just 6.0 seconds, and continues up to a top speed of 225 km/h (139.8 mph). According to the relevant standard for plug-in hybrid vehicles, however, the large SUV needs no more than 1.7 liters (138.4 US mpg) of fuel in the NEDC cycle (with 46 g CO2 per km (80.5 g/mi)). This value too sets new standards.
