Of course, as Audi states, the TDI with hybrid power is probably the perfect engine for a luxo-cruiser as it gives far lower fuel consumption (a claimed 19.34km/L, versus the petrol S5’s 15.6km/L) and seamless stop/start.
Though despite its extra torque, the TDI is also 0.1 seconds slower to 100kph than the petrol—which does the sprint in 4.7 seconds. All engines are limited to 250kph top speeds though.
So, that’s the news then—you can now buy your new S5 coupe or Sportback (there’s no word on a convertible TDI) with a diesel engine. But would you?
