    • Toyota revving the B58C out to 7800 rpm for the GR MKV Supra?

      It is somewhat confusing to keep track of BMW B58 engine variants but the B58C or B58C30O1 to be exact is the Toyota variant of the motor. BMW themselves does not rev the B58 engine past 7000 rpm.


      What is the GR MKV Supra? GR stands for Gazoo Racing which is an internal Toyota Motorsport team. Their expertise is used to improve and sharpen performance and this trickles down to the street car.

      Apparently the GR MKV Supra Concept is running the B58C motor at higher output and revving it to 7756 rpm as the screen grab shows. This would be a fairly large increase implying a revised head, springs, retainers, camshafts, etc.

      Does this mean we will see a high performance version of the A90 MKV Supra and B58 motor from Toyota? Time will tell.
