RUMOURS IN THE in the Japanese press this week suggested that Lexus is preparing a hard-core GS F model to sit alongside its M3-fighting IS F, powered by a version of the LFA’s 4.8 litre V10 engine.
Lexus’ European press office has thrown water on the rumours, however. In a short message issued on the company’s Twitter feed, Lexus said that the “LFA V10 is bespoke to LFA,” indicating that the 412kW bent-ten won’t be used by any vehicle other than the marque’s performance flagship.
Interestingly, Lexus declined to comment on the existence of a GS F project in its brief message. Is the company working on a hi-po luxury sedan to rival the likes of BMW’s M5 and Benz’s E63 AMG? We don’t know, but what is certain is that if a GS F is indeed in the works, it won’t be receiving a heart transplant from its supercar sibling.
The current M5 uses a naturally-aspirated V10 of similar capacity to the LFA’s motor, but the company is reportedly moving to a twin-turbocharged V8 for the next generation model.
Mercedes-Benz is also considering a similar tactic for its AMG models, meaning Lexus may soon be returning to forced induction for its future performance vehicles.
Yesterday we reported on rumors that the Lexus LFA’s 4.8-liter V10 engine would find its way into the upcoming GS F. Today Lexus of Europe is denying those rumors. Via Twitter, Lexus of Europe said that the high-revving V10 engine is bespoke, hinting that its pretty much exclusive to the Japanese brand’s new supercar.
We can’t say we’re surprised. While using the new high-tech engine in other models would help to cut down production costs and create a nice brand continuity, it also has the possibility of devaluing the LFA. After all, it doesn’t make much sense if you can get a car with the same engine for less than a quarter of the LFA’s $375,000 price tag.
Plus, while the 4.8-liter mill does make an impressive 553-hp, its torque of just 354 ft-lbs (which comes on at high rpm) is not only far less the the competition like the MErcedes E63 and Cadillac CTS-V, but would feel even less spectacular in a heavier platform.
