New engine, shared with recently launched S6 and S7 models, offers more torque and better fuel economy

The Audi S5 will switch from a turbocharged V6 petrol engine to a 345bhp mild-hybrid V6 diesel.

The powertrain, which will be used in both the coupe and Sportback versions of the S5, is the same as that introduced on the latest S6 and S7 models. It combines a 3.0-litre TDI diesel with a 48V mild-hybrid system and electrically-powered compressor, and produces 516lb ft of torque between 2500 and 3100rpm.

The diesel engine allows the S5 coupe to achieve 0-62mph in 4.8secs, the five-door Sportback version being 0.1secs slower. Both models are electronically limited to 155mph.

The 3.0-litre petrol V6 previously used in the S5 had a slightly greater output with 349bhp, although, at 369lb ft, it produced significantly less torque. Audi also claims the new unit consumes 19 per cent less fuel than the previous petrol version, at a claimed 45.56 mpg. That figure was calculated on the NEDC test cycle, derived from WLTP values.

The S5 retains an eight-speed tiptronic gearbox, along with permanent all-wheel-drive and a self-locking centre differential.

The TDI-powered S5 will go on sale in Europe in May, with a starting price in Germany of €65,300 (£56,590). UK pricing has not yet been set.

The 3.0-litre TFSI petrol engine will continue to be offered in the S5 in some markets outside of Europe.

I always loved Audi, and the 345bhp mild-hybrid diesel version I absolutely want to try, I can't wait to make a drive test. The innovation they made I like badly, especially when it comes to a 3.0-liter TDI diesel with a 48V mild-hybrid system and electrically-powered compressor, and produces 516lb ft of torque between 2500 and 3100rpm.

so after pretty much destroying the domestic diesel market with the emissions scandal and taking diesels out of Porsche the offensive on bringing them back into performance cars begins.

VW knows no shame in what it has done and I for one will continue to boycott its group models.

I was hoping that rumours of the S series Audi’s going diesel was a joke but clearly not. Amazingly bad timing. Had five of them over the years, will not make it to six.

The new S6/7 in Canada has the 2.9 V6 from the RS4/5 which is MUCH better than a stinky diesel! No matter what torque and mpg it has! I agree this is a F****** Stupid move by Audi.

I'm not automatically against diesel, but surely there is only a future for it if the emmisions of particulates and NOx are very low - equivalent to petrol at least. Any article on a new diesel form VAG group should surely have this at the top of the agenda?

The most recent diesels coming from Germany have been just as clean (and in some cases cleaner) than current petrols.
Mercedes recently had one of their diesels independently tested (I think it was the 3ltr) and it was producing zero Nox.
I for one think this is a smart move from Audi. They'll finally have a direct competitor for the 435d 540d 640d etc. And they seem to sell well. And anyone that wants a fast petrol Audi, well they'll still have the RS models.

I suspect it may be technically achievable, but from the brand that brought us dieselgate, reassurances about emissions are highly conspicuous by their absence! The car will drive nice I'm sure, potent diesel + auto + AWD is a nice way to get around - I have a 335d! But I wouldn't get another or similar unless I was 100% happy with emissions. Maybe a volvo v60 t8 instead.....
