The two-litre TFSI petrol engine combines forced induction, direct injection and a variable valve-lift system to produce its peak torque of 350Nm from 1500 to 4200rpm and deliver a claimed 155kW, pushing the Q5 from 0-100 in 7.2sec and on to 222km/h at the expense of 8.5 litres/100km .
The two-litre TDI uses common-rail fuel-injection to develop a claimed 350Nm from 1750-2500rpm and 125kW at 4000. Audi quotes 9.5sec for the 0-100km/h sprint and a top speed of 204km/h while using 6.7 litres/100km in the combined cycle.
The three-litre V6 TDI is the heavyweight of the Q5 range, churning out a claimed 500Nm from 1500 to 3000rpm and 176kW at 4000rpm. 0-100km/h, we are told, requires 6.5sec and top speed is 225km/h, at an average cost of 7.5 litres/100km.
The two-litre diesel drives through a six-speed manual gearbox but the two-litre petrol and three-litre diesel have a seven-speed, dual-clutch, semi-auto transmission that can be set to change gears automatically or as a quick-shifting manual, optionally also via paddles.
