In Japan, the Toyota GR Supra is split into SZ, SZ-R, and RZ trims. The SZ and SZ-R trims use a 2.0-liter four-cylinder engine, while the RZ trim uses a 3.0-liter turbocharged inline-six. For 2021, Toyota upgraded the RZ with more power and announced two special-edition models, one in Horizon Blue and the other in Matte Storm Gray Metallic. The Horizon Blue Edition also features new wheels and matching interior accents and is limited to 100 units.
The 3.0-liter engine in the Japanese GR Supra RZ is getting an update for the new model year. The outgoing model produced a claimed 335 horsepower, as does the current U.S. Supra, at 5,000 rpm, and 369 lb-ft of torque at 1,600-4,500 rpm. Weighing in at 3,351 pounds, it could race from 0-60 mph in 4.1 seconds (American market figure). The new Supra RZ will make a claimed 382 horsepower at 5,800 rpm and keeps the same torque number of 369 lb-ft but at at 1,800-5,000 rpm. It adds 22 pounds for a total weight of 3,373 pounds and can sprint from 0-60 mph in a slightly improved 3.9 seconds.
