The rebirth of Toyota's legendary Supra is a child of Germany and Japan. A platform and engine-sharing arrangement means that the Supra is siblings with the BMW Z4, giving German tuner Manhart the opportunity to add a Japanese car to its expertise with BMWs. Manhart's Supra GR-450 follows last year's package for the Z4, but with a slight edge to horsepower, making 10 more than the BMW. That's a total of 450 horses and 479 lb-ft of torque from the three-liter turbocharged inline-six thanks to Manhart's MHtronik Powerbox ECU remap. A new silencer with electronically-controlled valving also contributes to the increase, with H&R lowering springs or optional KW Variant 3 coilovers putting that power to the ground. Manhart accents the Supra's lines with red accents, new 20-inch wheels, and the option to disable automatic engine start/stop and the fake exhaust sound in the interior.
