Diesel power heads to Audi S5 line-up

By Ryan Hirons

A diesel performance car would surely be unthinkable in the current motoring climate — but Audi believes there’s room for one, resulting in the S5 TDI.

It’s the first time in the S5’s 12-year history it’s been powered by a diesel engine, with a 3.0-litre V6 sitting at its heart, albeit paired up to a 48-volt motor to create a mild-hybrid powertrain.


Efficiency is usually the game with diesel engines, though it seems Audi has focused on taking advantage of the torque benefits here. It sends a monumental 700Nm of it to all four wheels, along with 342bhp, resulting in a 0-60mph time of 4.6 seconds in coupe form and 4.7 seconds in its four-door ‘Sportback’ bodystyle. It’s fairly efficient too, with Audi saying it achieves a fuel economy figure of 6.2l/100km, or about 45.5mpg in more familiar terms.

The TDI also retains the chassis improvements the S5 carries over the regular A5, including a centre-locking differential and more focused suspension setup.

No word yet on full UK pricing and specifications for the Audi S5 TDI, nor if a petrol version will return to market, but expect to hear more ahead of the car’s late summer arrival on our shores.
