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 teases Frankfurt Motor Show concept... is it the RC Coupe?

With the teaser image of the concept car above and the announcement that Lexus will be premiering it to the world at the Frankfurt Motor Show on Tuesday, September 10, you know pretty much what we know. The Japanese luxury brand has decided to to say nothing more. Picture sleuthers have, however, suggested that it is a conceptual preview of either the RC Coupe or the hotter RC-F that will be revealed in Tokyo, or, less likely, the coming NX crossover - and that covers all the bases that we know of.
Along with that, Europeans will get to lay eyes on the GS 300h for the first time, the sport sedan powered by Lexus' 2.5L hybrid powertrain. You'll find a skosh more information in the press release below.

Lexus nixes RC convertible in favor of LS-based 3-row crossover [w/poll]

When Lexus unveiled the LF-C2 concept at the LA Auto Show last week, it did two things: it previewed the direction in which the Japanese luxury automaker's design department was looking for the immediate future, and it previewed a cabrio version of the RC coupe (to replace the IS Convertible) on the other. But the latter, according to new reports, was ruled out before the concept ever took the stage. Although the prospect of a convertible version was engineered right into the RC coupe's chassis, Motor Trend reports that plans to put such a vehicle into production were met with hostility by Lexus dealers, who were offered a two-door convertible instead of the three-row crossover they've been lobbying for. As a result – and with a finite amount of development bucks on hand – Lexus is reportedly listening to its dealers, axing the RC Convertible program and proceeding instead with a seven-seat crossover. Plans to stretch the RX were reportedly ruled out, so Toyota is reportedly proceeding instead with a new model to be based on the LS sedan. The new model would take aim at the likes of the Mercedes GL, Audi Q7 and Infiniti QX60 when it arrives in three years as a 2018 model. It's not the first time we've seen Toyota listen to dealers asking for a high-end people-mover: Earlier this year, dealers in Japan asked the automaker for a luxed-out minivan, prompting it to build the Esquire van just for the Japanese Domestic Market.
