I have a BMW M135i M-Sport convertible and an X3 3.0 M-Sport and I was wondering is the 0-100km/h times recorded in the Sport or Sport Plus setting or just the Comfort setting? Same question applies to other cars which have these extra performance settings. Should you not mention this in your articles?

To be honest, Nick, every car is subtly different, though as a general rule we generally performance test with all electronic aids (traction control, ESP, etc) deactivated as it usually results in the fastest time. We usually, though not always, go into some detail as to how we extract the best performance numbers.
