Toyota's rumoured revival of the much-loved and dearly-missed Supra sports coupe will be twinned with the next-generation BMW Z4, with both companies trading tech secrets to bring their next-generation swoopy two-doors to market before the end of the decade.

What we don't quite know, however, is precisely what will power the next Supra. BMW has its family of 3.0 litre turbo inline sixes to lean on - and most reports up until now have assumed this engine will be shared with Toyota, but fresh speculation says the next-gen Supra's powertrain may be an all-Japanese affair.

Talk within the Japanese motoring media suggests the Supra is in line for an all-new twin-turbocharged V6 being developed for the all-new Lexus GS and LS models.

According to the reports, the twin-turbo V6 – the first twin-turbo V6 from Lexus – will be good for 294kW/407Nm.

If true, this wouldn't be the first time a Toyota performance car has shared its powertrain with a Lexus. The fourth-generation Supra - which ended its production run in 2002 - utilised the same 206kW/441Nm twin-turbo 3.0 litre straight six as the Toyota Aristo, the Japanese-market version of the contemporary Lexus GS 300.

These latest reports don't mention anything about the a hybrid all-wheel-drive system that's also been rumoured for the Supra, though such technology may be reserved for a flagship performance variant rather than applied across the range.

That particular powertrain may be sourced from the high-end Lexus LC 500h, though specific details of that car also remain top-secret for now.
