I've encountered references to 8.8s in multiple locations. Manufacturers can manipulate 0-60 times so that they are low to attract certain consumers or high to assist insurance premiums. Same goes for quoted wattage values. It can depend on how they configure the vehicle for testing, i.e. what burden (in terms of energy) they determine to place on the engine during testing. This may no longer be the case due to 'regulation', but it was previously known that BMW conducted their tests with a light load to give high stated power values, whereas Skoda tested with a heavy load to give lower power values than those measured 'on the road'. In the case of the Fabis vrs, for example, the quoted value (130bhp, I believe) was consistently exceeded, and by a significant margin!
