The Audi 2.8 is a 90 degree V6. The Audi V6 has more torque than the VR6
in all versions, and the torque is available at lower RPMs.
Audi V6 2.8 12-valve (all) 172hp @ 5500rpm, 184lb-ft @ 3000rpm
Audi V6 2.8 30-valve (A4) 190hp @ 5500rpm, 207lb-ft @ 3200rpm
Audi V6 2.8 30-valve (A6) 200hp @ 5500rpm, 207lb-ft @ 3200rpm
VW VR6 2.8 12-valve 172hp @ 5800rpm, 173lb-ft @ 4200rpm
The VR6-equipped VWs feel livelier probably due to the lighter weight
of the cars, and also because the VR6 makes a "sportier" sound. These
are all nice engines.
