Despite plenty of on-again, off-again rumours, there will be another set of Toyota GT86 and Subaru BRZ twins and this time, they’ll ride on Toyota bones.

The current GT86 and BRZ are both built on an Impreza platform modified for rear-wheel-drive but, according to a source at Subaru, the new Subaru Global Platform (SGP) can’t be modified to accommodate such a requirement. That means the second-generation boxer twins either have to retain the current platform or move to Toyota’s TNGA platform. The same source said that neither company want to explore all-wheel-drive for the cars.

Moving to TNGA would save weight and increase torsional rigidity compared to the current model, as well as retaining rear drive. At the moment, the platform underpins the Corolla, Camry and RAV4. The A90 Supra uses BMWs CLAR (Cluster Architecture).

There’s not much in the way of performance news regarding the new GT86/BRZ but the GR HV Sports concept from 2017 could be a good preview of the upcoming sports coupe twins.

That concept was powered by a front-mounted hybrid engine with an unspecified amount of power (probably between 150kW and 175kW) sent to the rear wheels. It also featured a targa-style removable roof, LED cluster headlights, unique wheels and styling taken from the LMP1 TS050 Hybrid racer, as well as a pinch of the MR2-based 222D Group B prototype.

The coolest feature, however, was the gearbox. It's part traditional H-pattern manual, part six-speed automatic. It operates in automatic mode until the driver hits a button to engage the third pedal and change gears of their own accord. We won’t be surprised if that doesn’t make production.
