MT digs deep, learns more about hot Lexus RC coupe

As we patiently wait for the all-new Lexus RC to be unveiled at the Tokyo Motor Show in November, Motor Trend has dug up some tasty info on the Japanese automaker's new coupe for us to discuss. While we already knew some speculative, but credible, details on the upcoming two-door Lexus, MT reportedly has the dish on some details of the hotter RC F coupe (shown in the spy shots above).
The article says that the F will carry a six-figure MSRP and use a 455-horsepower, 5.0-liter V8 with cylinder deactivation, mated to an eight-speed automatic transmission. Carbon fiber body components will help reduce curb weight, and the scooped hood is said to optimize aerodynamics as the car will reach a top speed of around 186 miles per hour. Specific high-speed handling improvements include specially developed Brembo brakes, a beefed-up suspension, Michelin Pilot Sport PS2 tires and an automatic decklid spoiler.
As for other RC models, MT mentions the hybrid and V6 variants we already heard about, but it also says that the car could get a 2.0-liter turbo engine. This will probably be the engine used in the base model, which is expected to start at around $40,000. Head on over to Motor Trend for the full article, including a rendered image of the RC F.

The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.

BMW-Toyota partnership to spawn hybrid supercar

BMW and Toyota inked a partnership some time ago to develop green technology, and while we were excited by the idea of a reborn Supra with BMW's carbon fiber reinforced plastic slashing the curb weight or an ultra-efficient, hybridized 1 Series, the joint efforts have been rather limited. That's set to change, though, according to a report from Australia.
Motoring reports that the partners have come to terms on a sports car. And not just any sports car, but a lightweight, hybridized model, with a six-figure price tag. Lending a bit of street cred to that idea is the site's claim that Toyota is currently carrying out durability testing on the BMW i8. According to the site, the new model will slot into the spot left by the Lexus LFA, although based on the language used, it's unclear if this is the Tokyo-bound vehicle we mentioned several months ago.
Details on this potential car are limited, although Motoring claims it will use a Toyota hybrid system mated up to a BMW gas engine - likely the 4.4-liter, twin-turbo V8 found in the M5 and M6. That sounds pretty amazing to us, but we'd still advise taking this with a grain of salt. What would you like to see out of a joint-venture supercar from Toyota and BMW? Let us know in Comments, and have your say on the prospects of a hybridized, twin-turbocharged V8.
