One year after its debut, Toyota is raising the bar for the 2021 GR Supra with six-cylinder models that leap ahead with a power boost and retuned chassis, while the first ever four-cylinder turbo model joins the line.

The Toyota GR Supra brought the revered model back in a blaze of speed, with acceleration and handling performance that outshone even its illustrious A80 predecessor. For 2021, Toyota is keeping the pedal down, boosting output of the Supra's turbocharged 3.0-liter inline-six from 335-hp at 5000-6500 rpm to 382-hp at 5800-6500 rpm, a 14-percent increase.

Torque rises from 365 lb.-ft. at 1600-4500 rpm to 368 lb.-ft. at 1800-5000 rpm. The increased output results from a slew of upgrades throughout the engine. The new dual-branch exhaust manifold, with six ports instead of two, improves airflow and heat management. A new piston design reduces the engine's compression ratio from 11:1 to 10.2:1 in order to prevent abnormal combustion due to high boost.

The 2.0-liter four-cylinder engine shares much of its technology with the 3.0-liter inline-six, including a twin-scroll turbo, direct fuel injection and continuously variable timing on both the intake and exhaust camshafts. The variable intake valve lift system adjusts intake valve timing and duration. The bottom line is 255 hp and a stout 295 lb.-ft. peak torque.

Accenting the Supra's body are a rear black carbon fiber lip spoiler, matte black wheels, C-pillar graphics and carbon fiber mirror caps. On the 2021 Supra 3.0 Premium and A91 Edition, the front Brembo brake calipers are painted red and feature the "TOYOTA Supra" logo. All Supra models for 2021 will feature the 8.8-inch audio touch screen that is standard on the 2020 3.0 Premium model; the base model's 6.5-inch screen has been discontinued.
