Design, development and variant notes
P66 and P66/1 are naturally aspirated 4.0-litre DTM racing V8 engines. The P66/1 update for 2017 used a larger regulation intake restrictor and a higher stated output.
The later P66/3 is a twin-turbo, direct-injection development for LMDh racing. Its forced-induction specification must not be applied to the earlier naturally aspirated DTM engines.
