Apparently there will be a variant of the Lexus LF-A sold under the Toyota brand under the venerable Supra badge, but instead of using the LF-A’s 500hp V10, it will use a tuned up version of the Lexus GS450h’s 339hp 3.5 litre V6 hybrid engine paired with a 7-speed automatic transmission.
The hybrid powertrain, called the 2GR-FSE, is said to produce power equivalent to a 4.5 litre V8, hence the GS450h moniker. The S in the engine code represents the inclusion of Toyota’s D4-S twin injection system, which combines direct injection with traditional port injection. At low revs, the engine uses a combination of both direct injection and port injection, while at high load conditions only direct injection is used. This supposedly allows for better fuel efficiency.
The new Toyota Supra hybrid sportscar is expected to be unveiled end of 2007.
