To be clear, the Supra uses the same engine and with the same ratings everywhere; only the Z4 has different engine models and ratings for UK vs. non. .....but I agree with both previous posters: the Supra is putting out more power than advertised but the carwow 12.0 sec flat time is likely not that accurate.

Based on the dyno results (https://g29.bimmerpost.com/forums/sh....php?t=1621271) for both the Supra and the North American Z4 M40i, it would seem than the North American Z4 M40i has a significant power advantage over the Supra which would imply a different drag race result than the one CarWow posted.

...that's about as clear as I can get.

Cheers,

Video already posted above but posting again for emphasis and I'm sure there'll be other comparison but it would appear the significant power advantage of the NA Z4 M40i just makes it about on par with the M40i (0-100km/h, Supra beats it by 0.1s).

I think you mean on par with the supra. ....yes, it would appear that this one test implies the two are at performance parity despite the rated hp, dyno results and manufacturers claims. More tests will confirm or dispel.

Cheers, Dave
