Audi adds petrol V6 to Q8

Audi is expanding the engine line-up for its Q8 luxury SUV by adding two V6 engine versions, a powerful 3.0 TFSI petrol and a lower power variant of the 3.0 TDI diesel.

The new Audi Q8 55 TFSI is equipped with a six-cylinder spark-ignition engine with three litres of engine displacement and direct injection that produces 250 kW (340 PS) and maximum torque of 500 Nm (368.8 lb-ft). The turbocharged petrol engine Audi Q8 sprints from 0 to 100 km/h (62.1 mph) in 5.9 seconds. Its maximum speed is electronically limited to 250 km/h (155.3 mph).

The second new engine is an additional version of the three-litre diesel. It provides 170 kW (231 PS) of power and also develops ample torque of 500 Nm (368.8 lb-ft). From a standing start, the Audi Q8 45 TDI accelerates to 100 km/h (62.1 mph) in 7.1 seconds and on to a top speed of 233 km/h (144.8 mph).

All engines in the Audi Q8 work in conjunction with the mild hybrid system, which can reduce consumption by up to 0.7 liters per 100 kilometers in customer operation. Its most important components are a lithium-ion battery and a belt alternator starter (BAS) that supplies the 48 V main electrical system of the SUV coupe with electricity. When decelerating, the BAS enables up to 12 kW of energy to be recovered and feeds this into the battery. At speeds between 55 and 160 km/h (34.2 and 99.4 mph), the Q8 can coast for up to 40 seconds with the engine switched off when the driver lets off the accelerator. The BAS then restarts the six-cylinder quickly and very smoothly. The start-stop range begins at 22 km/h (13.7 mph).

An eight-speed tiptronic and the quattro permanent all-wheel drive also take care of power transfer in the new engine versions. Both Q8 variants are fitted with 19-inch wheels with 265/55 tyres as standard. The suspension with damper control and the Audi drive select dynamic handling system are also part of the standard equipment, along with the top infotainment system MMI Navigation plus and the Audi virtual cockpit. Operation is via two touchscreen displays with haptic and acoustic feedback. UK prices are to be confirmed.
