Coming from an automotive marketing company that counts Lexus as a client, this AMCI video comparing the IS-F with the BMW M3 and Audi RS4 does seem more than a little bias, but that doesn’t stop it from being a great watch:
To be fair, test driver Dave Sherman doesn’t proclaim the IS-F the king, but rather a legitimate contender in the super sports sedan market. Still, I wouldn’t take the acceleration or the brake tests very seriously, they seem to lack any sort of methodology. The domination by the IS-F is far too overstated to be accurate.
