Audi 3.0-litre V6 TFSI

Audi and Porsche jointly developing V6 and V8 engines

August 14, 2015

Audi and Porsche, the luxury and performance car brands of the Volkswagen Group, will work together on new V6 and V8 engines, says a fresh report from Autocar.

According to the report, development of the new family of V6 and V8 engines is progressing under the codename ‘KoVoMo’, abbreviation for ‘Konzern Vee Otto Motoren’ that is in German. The new engines should be offered in future Audi, Porsche, Bentley, Volkswagen and possibly Lamborghini models.

The German companies have entered a joint engineering programme to co-develop V6 and V8 petrol engines based around a common 90° architecture. The plan is to keep the individual cylinder capacity for both the engines the same – 500 cc, thus making the V6 engine’s displacement 3.0-litres and the V8 engine’s displacement 4.0-litres.

V6 and V8 petrol engines are used in many of current Audi and Porsche models. The engines are planned to be replaced by the new jointly-developed engines, as per the report. Both engines will feature conventional gas-driven turbocharger in the first production phase. Citing undisclosed sources, the report says that electric turbocharging may be introduced later.

Moreover, the undisclosed sources also suggest that the tolerances built into the engines’ architecture will allow them to be scaled in capacity. An entry-level V6 engine having 2.5-litre displacement may be introduced, fitted with the same Atkinson-cycle combustion process like that of the new 2.0-litre TFSI four-cylinder turbocharged petrol engine that was announced for the fourth generation 2016 Audi A4 at the Vienna Motor Symposium in May.
