Toyota's 2021 GR Supra proves you can teach an old dog new tricks.
The 2021 Toyota GR Supra revives an old classic, and adds more power and speed. It will also offer consumers the first-ever four-cylinder turbo model.
The company announced that two new GR Supra models—GR Supra 3.0 and GR Supra 2.0—will be at dealerships starting in June 2020.
Toyota is positioning the Supra 2.0 model as an entry model to the sport name plate. It features a 2.0-liter inline four-cylinder engine sharing 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 295 lb.-ft. peak torque at 1,550 to 4,400 rpm.
The Supra 2.0 uses the same 8-speed automatic transmission as the 3.0, and Toyota projects 0-60 mph in 5.0 seconds, which will make it Toyota’s second quickest vehicle in the lineup. The Supra 2.0 has the same electronically limited 155-mph top track speed as the 3.0, and its fuel consumption will be lower.
At 3,181 pounds, the 2021 Supra 2.0 is more than 200 pounds lighter than the Supra 3.0. Engineers spread the weight reductions throughout the car:
- The Supra 2.0 uses smaller front brake rotors than the Supra 3.0 (330mm x 24mm vs. 348mm x 36mm), and with single-piston calipers vs. four-piston
- The Supra 2.0 does not have the Active Differential and Adaptive Suspension used on the 3.0 model
- A four-speaker audio system is standard, vs. the Supra 3.0’s 10-speaker system
- Supra 2.0 seats are manually adjustable, vs. 14-way power-adjustable in the 3.0
The 2021 Supra 3.0 got some upgrades, providing more power and even better handling.
Toyota boosted 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 365 lb.-ft. at 1,600-4,500 rpm to 368 lb.-ft. at 1,800-5,000 rpm.
The increased output results from upgrades throughout the engine. The new dual-branch exhaust manifold, with six ports instead of two, improves heat management. A new piston design reduces the engine’s compression ratio from 11:1 to 10.2:1.
The greatly revised engine produces higher torque at higher rpm and retains the eagerness to rev with turbine-like smoothness. Toyota projects that the new engine will reduce the Supra 3.0 model’s 0-60 acceleration time to 3.9 seconds, from 4.1. The 8-speed automatic transmission with paddle shifters carries over for 2021.
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.
Toyota also announced the GR Supra GT4 will be coming to dealerships in August of 2020.
The GR Supra GT4 is based on the GR Supra and is developed and produced by TOYOTA Motorsport GmbH (TMG).
Make no mistake, the GR Supra GT4 focuses on performance.
It features a three-liter inline six-cylinder engine with single twin-scroll turbocharger has been tuned to 320kW (430hp) with a 7-speed sports automatic transmission with paddle shifters and the mechanical limited slip differential driving the rear wheels. An Akrapovič exhaust system will be fitted and Ravenol will provide first-fill lubricants.
The front splitter and rear wing are made of natural fiber composite, contributing to an overall weight of 1,350kg (2,976 lbs.). Following the specification of the GR Supra road car, the front suspension will be MacPherson strut, and rear suspension will be multilink with KW dampers at the front and rear.
The braking system is enhanced using a dedicated brake caliper for racing, six-piston front and four-piston rear, while running on Pirelli tires.
Safety will be a priority and the GR Supra GT4 will be installed with a high-strength roll cage on the lightweight steel body, and an FIA-standard racing seat with six-point harness. The interior will feature a carbon fiber instrumental panel with a display and steering wheel specifically designed for GT4 competition.
From an infotainment perspective, Toyota will offer an 8-inch touchscreen system with wireless Apple CarPlay compatibility (no Android Auto).
