The 2.9-litre twin-turbo V6 engine was developed kointly by Audi as part of a new modular engine family known under the working title KoVoM.
The second generation of the Audi R8 currently only uses a 5.2-litre naturally aspirated V10 engine which also powers the Lamborghini Huracan.
In the R8, the engine produces either 533bhp and 540Nm of torque (for the base R8) or 602bhp and 560Nm of torque (R8 V10 Plus).
The new 2.9-litre twin-turbo V6 engine, was first seen under the hood of the newly unveiled second generation Porsche Panamera where it produces434bhp and 550Nm of torque.
However, that power and torque is delivered at a relatively low 0.4bar of turbocharger boost pressure.
Audi is expected to use a slightly more powerful version of the engine for the entry level version of the R8. This engine will replace the 4.2-litre naturally aspirated V8 found in the first-gen R8.
The new engine is also expected to make its way onto the and the soon-to-be-confirmed RS Q5 RS4 and RS5 sedans along with the RS Q5 SUV.
