Toyota is readying a new high-performance iteration of the GR Supra. This new model could be called the Supra GRMN and could come with a significant increase in power and a tighter, more composed chassis. Sources tell us that Toyota is testing a new variant of the GR Supra replete with a fixed rear wing and slightly different front and rear bumpers along with a lowered stance.
- Hotter Supra could share engine with BMW M2, M3 and M4
- 0-100kph time to dip under current model's 4.3 second run
- Could get the GRMN suffix
Under the bonnet, the hot new Supra could go as far as trading the BMW Z4-sourced ‘B58’ straight-six – which puts out 340hp and 500Nm – for M division’s tuned ‘S58’ powerplant. That engine, used by the BMW M3 and M4, swaps the B58’s twin-scroll turbochargers for a pair of single-scroll units and features a revised piston design with a larger bore and shorter stroke, as well as stronger internals to support the resultant power boost. The result is a versatile engine with a wide range of outputs: from 460hp and 550Nm in the new BMW M2 to 560hp and 550Nm in the limited-run BMW 3.0 CSL.
Details remain firmly under wraps at this early stage, but should the new car adopt the S58, its 0-100kph time is likely to be cut well below the current car’s 4.3 seconds. There is a speculation that a hot new Supra could revive Toyota’s GRMN nameplate, which stands for ‘Gazoo Racing, tuned by the Meister of the Nürburgring’.
The badge has only been used in Europe so far, for a supercharged hot version of the previous-generation Yaris. The Z4, with which the Supra shares its underpinnings, was subtly restyled earlier this year but received minimal mechanical alterations.
