How different can two cars be if they have the same drivetrain and chassis? We drive the mechanically identical BMW Z4 M40i and Toyota GR Supra back to back.

It took not just one but two drives for the AutoApp team to decide if they prefer the BMW Z4 M40i or the Toyota GR Supra. Both feature identical mechanicals but built on very different philosophies.

It’s no secret that both cars are based on the Z4 so the BMW should enjoy the ‘home ground’ advantage since the engine, gearbox and chassis comes from the German carmaker. However, the Toyota has a few surprises up its sleeve with a lower kerb weight. It somehow manages to incorporate the typical lithness and finesse that Japanese sports cars are known for.

It’s been over 25 years since a new Toyota Supra was launched so this is one car we have been looking forward to driving. When its predecessor came out, it was seen as a Ferrari-challenger. Today, the GR Supra is targeted at cars like the Audi TT and Porsche Boxster.

The BMW Z4 on the other hand, has matured nicely into a car that can handle touring duties as well as it can a B-road blast.

So which would we take home? You’ll have to watch our video to find out. Let us know what you think in the comments and don’t forget to subscribe so you won’t miss more videos that will be coming out.
