In announcement just before the 2018 Goodwood Festival of Speed, Toyota disclosed that all-new Toyota Supra will stay faithful to its heritage by featuring an in-line, front-mounted six-cylinder engine as well as a rear-wheel drive system. However, Road & Track has come to acquire a document indicating that the new Supra might be also powered by a turbocharged four-cylinder engine.
While the prototype version of the Toyota Supra – wrapped in red, black, gray and white camouflage – impressed visitors at the 2018 Goodwood Festival Speed with its daily runs from July 12 to 15, this isn't the final model yet. This working concept essentially confirmed the arrival of the Supra, providing a glimpse on how the final model would look like. But despite showing the Supra to the public at Goodwood, Toyota didn’t disclose specific details, but only basic features and estimated numbers.
Not satisfied with the current amount of information available for the new Supra, Road & Track squeezed some connections and managed to get hold of a document from ZF, the German transmission maker that will supply the gearboxes for the Toyota’s newest sports car. This document is basically a transmission catalogue for the Toyota Supra, showing the Supra getting multiple entries under both the J29 and GT86 platform designations. According to the document, the power for the Supra will be provided by two engines: a 2.0-liter B48B20 and a 3.0-liter B58B30, both mated to an eight-speed ZF 8HP automatic transmission.
The 2.0-liter B48B20 is a turbocharged four-cylinder engine from BMW, delivering 265 PS (262 hp or 195 kW) of output. On the other hand, the 3.0-liter B58B30 is a single-turbo inline-six engine -- also from BMW – that is capable of providing 335 hp. According to this internal document, both engines for the Supra will be paired to the ZF-8HP51HIS 8-speed automatic transmission that has been mated to B48 and B58 engines in a number of BMW vehicles.
The possibility of Toyota Supra served by a four-cylinder engine was confirmed by Supra chief engineer Testsuya Tada to Chris Perkins, web editor at Road & Track, at the Goodwood Festival of Speed. Tada told Perkins that compared to the in-line six version, the four-cylinder Supra will weigh less, have a better weight distribution as well as a sharper-feeling turn-in.
In another interview at Goodwood, this time with Autocar, Tada said the Supra will weigh between 200 kg and 300 kg (between 440 lbs and 661 lbs) less than the Lexus F-Series. Since the Lexus GS F and the RC F weigh 1,829 kg (4,034 lbs.) and 1,795 kg (3,958 lbs.), respectively, the Supra should tip the scales at around 1,500 kg (3,307 lbs), with an ideal front-to-rear distribution of 50:50.
Toyota is expected to unveil the final production form of the Supra at the start of 2019.
