Toyota GR Supra gets first 4-cylinder turbo engine

By CARSIFU | 14 February 2020

DAYTONA, Florida: For 2021, the six-cylinder GR Supra 3.0 models leap ahead with a power boost and retuned chassis, while a new GR Supra 2.0 four-cylinder turbo model joins the line.

The first 1,500 Mk. V Supras were Launch Editions, and for 2021 Toyota is offering 1,000 new A91 Editions. This special edition Supra will have the 3.0-liter inline-six-cylinder engine.

On the 2021 Supra 3.0 Premium and A91 Edition, the front Brembo brake calipers are painted red and feature the “Toyota Supra” logo.

For 2021, Toyota is keeping the pedal down, boosting output of the Supra’s turbocharged 3.0-liter inline-six from 335 hp at 5,000-6,500 rpm to 382 hp at 5,800-6,500 rpm, a 14-percent increase.

Torque rises from 495Nm at 1,600-4,500 rpm to 499Nm at 1,800-5,000 rpm.

The 8-speed automatic transmission with paddle shifters carries over for 2021.

Seeking increased roll resistance and enhanced cornering stability, Toyota retuned the Supra 3.0 chassis, adding lightweight aluminum braces that tie the strut towers to the radiator support to increase lateral rigidity, along with front and rear bump stops and new damper tuning.

Revised programming for the electric power steering (EPS), Adaptive Variable Suspension (AVS), Vehicle Stability Control (VSC) and Active Differential works in concert with the hardware changes to make the 2021 Supra more stable through quick transitions, such as compound turns.

Meanwhile, the 2.0-liter inline 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 at 5,000-6,500 rpm and a stout 400Nm peak torque at 1,550 to 4,400 rpm.

The Supra 2.0 uses the same 8-speed automatic transmission as the 3.0-litre.
