New Toyota Supra may get a twin-turbo Lexus V6

We've heard endless rumors that a successor to the much loved and much missed Toyota Supra is in the works. Toyota hasn't done much to deny these conversations. On the contrary, the FT-1 concept from two years ago and the partnership with BMW have only fueled the fire. Now, talk of a new Lexus engine has led to speculation about the supposed Supra's powertrain. To be clear, this is mostly heresay. Few things have actually been confirmed, but based on what we know a few conclusions can be drawn. We know that BMW and Toyota are working on a joint product. We've seen mules testing out in the wild. In BMW guise, the possibly Austrian-built car will more than likely powered by turbocharged inline four and six-cylinder engines. Unless Toyota wants to use Bimmer power, they'll need to shoehorn one of their own under the hood. That leads us to this rumor of a twin-turbocharged V6 that will presumably power the new Lexus GS and LS. Japanese automotive publication Mag-X first reported on this engine. It was then picked up by YouWheel and Car Keys. Mag-X cites Toyota insiders and even gives an engine code, 943F. This engine allegedly will make more than 400 horsepower and more than 300 lb-ft of torque. While unconfirmed, this makes sense for Lexus. Nearly every luxury competitor has a six-cylinder engine with forced induction. While Toyota has previously had turbocharged inline-sixes, they've never produced a factory turbo V6. Every automaker is downsizing engines in an effort to meet fuel economy and emissions regulations. Toyota and Lexus will follow suit. Taking that V6 and tuning it for a performance application is a solid, if unverified, possibility. Related Video:

Lexus takes to Pikes Peak in RC F GT Concept

Lexus is gearing up to take on Pikes Peak with the RC F GT Concept you see here, developing the new racing prototype for the venerable hillclimb event. Different from the more extreme GT3 and GT500 racing concepts we've seen to date, the new GT concept is more closely based the road-going RC F. Only it's leaner and meaner and ready to take on the grueling 12.4-mile race to the clouds and all its 156 turns. The RC F GT packs the same 5.0-liter V8 and eight-speed automatic transmission as the production model. The major difference is that it weighs some 800 pounds less, thanks largely to the widespread use of carbon fiber body panels and polycarbonate windows. It also incorporates a more aggressive aero kit and rolling stock, and allows the technicians to tune the engine for competition applications. To tackle the Peak, Lexus is handing the keys over to none other than Justin Bell, the former GT2 class winner of the 24 Hours of Le Mans and the FIA GT Championship. He'll be fielding the RC F GT in the Time Attack class for production-based vehicles, while providing Lexus engineers with valuable performance data and the chance to develop components for future applications. Two years ago, the IS F CCS-R prototype competed in the same event, and served as a test bed to develop the powertrain that went into the RC F that followed.

(June 22, 2015) – On June 28th, Lexus will compete in the Time Attack class of the Pikes Peak International Hill Climb. The luxury automaker will be campaigning the all-new RC F GT Concept, a vehicle that builds upon the legacy of the IS F CCS-R vehicles that last competed at Pikes Peak in 2013. This historic event, now in its 93rd running, is a race against the clock that tests man and machine with the changing elements, altitude, and a treacherous 12.42 mile, 156 turn course that winds up the peak from 9,390 feet up to the 14,115 foot summit. The new Lexus will be piloted up the mountain by British driving ace, 24 Hours of Le Mans winner, and automotive media personality Justin Bell. "With very little time behind the wheel, the RC F GT Concept has already proven fast and easy to drive, very much like the production models, actually.

2014 Lexus IS350 F-Sport

Is A New Kind Of Lexus Hiding Under That Radical Skin?
When the now-outgoing Lexus IS generation was launched back in 2006, the company would not have been wise to bring the compact luxury sedan to be driven by journalists to a track like Driveway Austin Motorsports. Taking along a BMW 335i for comparison loops would have proved an ill choice as well.
Our own Jonathon Ramsey found the current-generation Lexus IS250 to be fairly nimble over a tightly wound autocross course, when he drove it back-to-back with the prototype version of this 2014 IS a few months ago. Our track for testing the fully realized version of the IS350 F-Sport meanwhile - again with the 2013 version along for competitive driving - was on a circuit designed to string together recreations of some of the best tracks in the world. Laguna Seca, bits of the Nürburgring and sections inspired by Imola and Ferrari's Fiorano test track all make for a far more enticing road course than you'd expect to find plunked down in a nondescript area a few miles east of downtown Austin. Critically, this environment highlighted what strides Lexus has made in the sport sedan race with its new IS.
