Its 4.2 - litre V8 engine is identical to the RS5 coupe's, boasting 444bhp and 317 lb ft. Thanks to good
old natural aspiration — there's no turbo or supercharging here — maximum power arrives at 8250rpm, rewarding you for hanging onto every gear.
Porsche's decision to stick with
natural aspiration has been entirely justified by the new engine, which is more than good enough to stand comparison with the
old Metzger unit of the 996 and 997 GT and Turbo models.
