Currently reading: Audi and Porsche to work together on new V6 and V8 engines
New jointly developed V6 and V8 engines will appear in a number of upcoming vehicles from Volkswagen Group brands

Audi has entered a joint engineering programme with Volkswagen Group sister company Porsche to develop a new range of turbocharged V6 and V8 petrol engines, Autocar can reveal.

The engines are based around a common 90deg architecture and are planned to feature a common 500cc individual cylinder capacity, giving the new V6 an overall displacement of 3.0 litres and the new V8 4.0 litres.

Set to replace Audi’s and Porsche’s current V6 and V8 petrol units, the engines will feature gas-driven turbochargers in the first stage of production. However, insiders have hinted that electric turbocharging may be introduced at a later date.

Tolerances built into the architecture of the new engines will allow them to be scaled in capacity, according to sources. It is suggested that Audi may introduce an entry-level 2.5-litre version of the V6 fitted with the same Atkinson-cycle combustion process, as seen on the company’s new 2.0-litre petrol engine in the A4 2.0 TFSI Ultra.

The new family of V6 and V8 engines, which go under the internal codename KoVoMo (a play on the German words Konzern Vee Otto Motoren), are destined to appear in future Audi, Porsche, Bentley, Volkswagen and possibly Lamborghini models.

Nothing to do with chinese tax levels at all then, oh no sir.

One assumed they were already cooperating.

which is said to be being developed, in reality a supercharger?

Recommended further reading: Autocar car news 21/9/12 "Audi reveals electric turbocharger technology". Needless to say, there was some forum discussion!

Good point but I think, technically, it is neither. Superchargers are mechanically driven. Somebody needs to come up with a new name...

Presumably VAG has a key performance indicator of producing 76 press releases each week, irrespective of the diluted drivel they contain.

Not the first time, hopefully not the last:

Autocar, (this time Greg), does not know the difference between the Miller cycle and the Atkinson cycle.

How can this be possible? The oldest car magazine?

Good spot @coolboy! So if I'm understanding correctly, for a given capacity, an Atkinson (e.g. as in a Prius) produces less power than an Otto (ordinary engines), but by adding supercharger and inter cooler to an Atkinson ("Millerising" it), it produces more power, and is more efficient but more expensive to make. A kind of alternative to an Atkinson being combined with electric/hybrid?

So the same basic engine will power "future Audi, Porsche, Bentley, Volkswagen and possibly Lamborghini models."

So very SAD, though not surprising. These ONCE DISTINCTIVE and great marques, that used to make interesting and distinct engines that were so intrinsic to each marque's character, are going even farther down the path to being little more than variations of the same thing. Yes, I know about Porsche's origins and history, but this is yet another big step towards the convergence of these marques -- merely brands now -- and their each becoming merely another version of the other.
