of Audi diesel
tackle most jobs with its 350Nm coming in at a handy 1750-2500 revs, and the 125kW at 4200 revs.
Acceleration to 100km/h is hardly blistering at 8.9 seconds, and the top speed sits well below the rest of the A6 range at 218km/h.
The 2.7-litre benefits from its 400Nm coming in at 1400 revs — a level closer to those usually seen driving 18 wheels than four — and digging in there until 3500 revs. The 140kW arrives in a fairly narrow band between 3500 and 4400 revs.
It takes a full second less than the 2.0-litre to hit 100km/h and manages a top speed of 277km/h.
At $74,500 and with consumption of 5.8 litres for 100km, the smaller diesel gets the full LCT-free tick and an approving nod for CO2 emissions at 153g/km, while the larger-engine 2.7-litre unit’s 6.4 litres/100km pays the whack only on the difference between the base price of $75,000 and it’s $84,500 tag, and still does well with CO2 emissions at 169g/km.
Audi has done well with its TDI engines, increasing sales across all models by more than 500 a year in the past three years, and is on track to do the same for 2009.
The new A6 arrivals will lend a hand with that, with Audi expecting each to take up 10 per cent of sales.
Luxury on the road: the Audi A6 2.0 TDI has proved popular, increasing sales across all models by 500 a year.
