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.

Lexus RC F Coupe puts on a brave face for Detroit

With less than a week to go until the 2015 Lexus RC F makes its debut at the Detroit Auto Show, Lexus has given us a sneak peek at its upcoming performance coupe. Earlier this week, Autoblog was granted were the opportunity for an intimate studio photo shoot with the RC F outside of the bright lights and big crowds sure to surround the coupe at Cobo Hall next week.
Compared to the hybrid version of the all-new RC we saw at the Tokyo Motor Show last year, the RC F has noticeably more aggressive styling. The cartoonishly oversized Lexus spindle grille gets a mesh insert pattern and is flanked by massive intakes in the lower fascia. To make room for what is expected to be a bigger V8 engine, the hood sits higher and is vented, but like many details about the RC F, Lexus is keeping the engine's size and output under wraps (although we have a sneaking suspicion it'll have 460 horsepower).
A trio of 19-inch wheel options will be available (including a set that is hand-polished), and the side sills and rear fascia have been modified for F duty. The biggest styling change on the RC F, however, is the LFA-inspired active rear wing that rises at speeds above 50 miles per hour for improved traction and stability. Carrying over cues from the current IS F, the RC F features air outlets behind the front wheel openings and angle-stacked exhaust outlets at the rear of the car.
