According to Toyota Chief Technology Officer Hiroki Nakajima, the new four-cylinder engine range is a “game changer”. The upcoming powertrains feature 1.5 and 2.0 liter displacements, and although they will be optimized primarily for electrification, the fun factor will not be ignored. At least that’s true of the 2.0-liter turbo engine that engineers installed in a dismantled Lexus IS for testing purposes last year.

For the Tokyo Auto Salon 2025, the four-cylinder was installed in a mid-engine test car based on a GR Yaris. In the press release, Toyota did not provide any information about the output of the 2.0-liter turbo engine, but suggested in an interview with Japanese journalists during TAS that it could produce over 400 hp. During the Multipathway workshop last May Car clock We learned from Nakajima that the goal is 400 hp, which technically corresponds to 394 hp. However, there seems to be room for more.

At TAS 2025, Nakajima suggested it could pack an even bigger punch. When asked by a reporter, he replied: “Is it a 400 horsepower engine?” Of course, that could mean less than Toyota’s original estimate. However, the original version shown last year already had 400 horsepower, so we should expect more rather than less. In 2024, a peak torque of 369 pound-feet (500 Newton meters) was estimated.

A 2.0-liter four-cylinder turbo engine with more than 400 hp is not new, considering that AMG’s “M139” in the “45”-badged cars produces 416 hp. Installed longitudinally in the extremely controversial C63, the “M139l” produces a massive 469 hp. Even the rare Mitsubishi Evo X FQ-440 MR had 440 horsepower a decade ago, although that car was full of engine modifications.

Nakajima told Car clock that a smaller version of the 2.0-liter turbocharged engine is planned with an expected output of 300 hp (296 hp) and 295 lb-ft (400 Nm). The unrestricted four-cylinder mill will produce more than 600 horsepower in racing cars. This engine can be installed both transversely and longitudinally. Toyota is already using a 2.0-liter turbo four-cylinder in a sports car via BMW and its B48 engine, although not for long. The current Supra is about to be retired, but the nameplate remains. It remains to be seen whether the next-generation Supra will feature the “G20E.”
