Lexus RC F is a predatory sport coupe with a 450-horsepower beating heart

Take a look at that face. We can't be the only ones who see an automotive Predator staring back, right? Certainly, the Lexus RC F Coupe boasts a visually striking design that some are going to love and others are going to hate, but we can at least appreciate that it's aggressive, especially compared to the standard RC Coupe that we saw at the Tokyo Motor Show. And with good reason - there's a 5.0-liter V8 engine sitting under that massively domed hood with "more than 450 horsepower," along with a newly calibrated eight-speed automatic gearbox.
Interestingly, Lexus has tuned the RC F's engine to run on an Atkinson cycle under most circumstances, while it switches to the more typical Otto cycle when more power is required, presumably using some sort of advanced variable valve timing technology. Helping put that power to the ground with all those ponies wreaking havoc underhood is a torque vectoring differential, a first from Lexus.
Also involved in keeping the RC F planted is an aero package that includes wings and ducts galore. The headline bit is an active rear wing that deploys at 50 miles per hour and retracts back into the deck when the car drops back to 25 mph. A clear-coated carbon fiber roof can optionally join that carbon rear wing. There are apparently going to be three 19-inch wheel options, including the ones you see in our live image gallery above.

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.

Lexus LF-FC concept is a preview of the next LS [w/video]

As far as flagship luxury sedans go, the Lexus LS is one of the oldest on the market. But the upscale Japanese automaker is out to fix that in short order. And to give us a taste of what's to come, it's presenting the concept you see here at the Tokyo Motor Show today. Called the LF-FC, the show car clearly points the way forward for the next-generation LS. The design adopts the latest take on the brand's "L-finesse" styling language, with a large, spindle-shaped front grille leading to sharp creases cutting their way across the entire surface. Lexus refers to the roofline as approaching that of a four-door coupe, though it clearly places more of an emphasis on rear-seat space. Power comes from a conceptual hydrogen fuel cell whose components have been scattered throughout the vehicle to optimize weight distribution. The fuel cell drives the rear wheels and sends power to hub motors in the front wheels as well for all-wheel-drive capability. Those 21-inch rims are made of carbon fiber, with aluminum spokes, to minimize unsprung weight. Naturally, Lexus has equipped the concept with all the latest electronic aids to track the flow of traffic and even drive autonomously through it. Of course a vehicle like this is designed around the driver and occupants. The white and brown interior space features four individual bucket seats, because really, who wants to dream of riding in the middle? Interior appointments look suitably tasteful, all done in satin-finish wood and metal with white and brown leather, and would look at home on the next generation of first-class aircraft cabins. Lexus has equipped the concept with gesture control that incorporates a floating holographic image to show users where to place their hands to operate the audio and ventilation systems touchlessly. In typical concept style, the LF-FC sits wider and squatter than the production sedans at which it takes aim. More telling, however, is the overall length: at 208.7 inches, it's a few thumbs longer than even the extended version of the current Lexus LS, and a touch longer than the current long-wheelbase Mercedes S-Class, Audi A8, BMW 7 Series, Jaguar XJ, and Maserati Quattroporte. We're looking forward to seeing the production version in the form of the next LS in due course to see how it measures up against the competition, and not just in terms of size.
