The highly anticipated Toyota Supra finally made its first appearance at the 2018 Goodwood Festival of Speed, but it was disappointingly wrapped in camouflage. Toyota hasn't given any details about the production Supra, but it has been heavily implied that the car will be powered by a BMW-sourced 3.0-liter turbocharged inline-six producing 335 horsepower and 369 lb-ft of torque. This may not the Supra's only powerplant, as Road & Track reports the existence of an inline-four model below the inline-six.

A recently discovered transmission catalogue document from German transmission maker ZF, shows various implementations of the eight-speed 8HP automatic transmission in production and pre-production cars for 2018. The Supra is listed in the document with multiple platform designations including J29 and GT86. GT86 is likely the inline-six model using BMW's B58B30 engine. The J29 model will reportedly use BMW's B48B20 turbocharged four-cylinder engine producing 262 hp. The BMW Z4 roadster is also listed in this document, with the chassis code G29.

Although the Z4 should have the same engine as the Supra, the document reveals a more potent 375 hp version of the BMW, compared to just 335 in the Toyota. Supra chief engineer Testsuya Tada confirmed that there will be a four cylinder Supra at the Goodwood Festival of Speed. Tada says the four cylinder will be lighter and have "much better weight distribution." Unfortunately, the ZF document makes no mention of a manual transmission, which may disappoint a lot of enthusiasts.
