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.

Lexus LF-C2 Concept teased ahead of LA Auto Show debut

Lexus is bringing an appropriate concept to the 2014 LA Auto Show in the form of the topless LF-C2 Concept you see teased above (click on the image to enlarge). We really don't have a lot information on this one as of yet, although we only have just over a week to wait.
We can, however, speculate. Does the LF-C2 preview a convertible LF-LC? Maybe. Could this show off a replacement for the IS Convertible, maybe modeled on a RC coupe with a folding-metal roof? That's also a pretty fair possibility.
Proving that social media reveals have well and truly jumped the shark, Lexus will release further teasers of the LF-C2 during a three-day social media campaign. That'll culminate with its LA Auto Show debut on November 19.

8 things you should know about the Lexus LC 500h powertrain

Lexus unveiled the LC 500h today in The Netherlands, and I got to take a look inside its new hybrid system. On one hand it seems like a box of magic – it combines two seemingly incompatible transmission types into one package. But that's also the ingenious simplicity of the thing. We don't have all of the details on how it all works yet, but here's a rundown of the high points.Efficient business in front, low-key party in the back. What makes it all work is the mullet of transmissions. For the new hybrid transmission, Lexus used the Toyota Hybrid Synergy Drive/Lexus Hybrid System – which consists of an e-CVT with a planetary gearset and two electric motors (one for charging the battery, the other for motivation and regen) – and grafted a conventional four-speed automatic onto the back. The two units actually coexist in one package, with the e-CVT making things efficient and the automatic expanding the capabilities. So at the low end, the system can deliver more torque, and the engine can also run at lower rpm on the highway. It's all thanks to those fixed gear ratios, and it's surprisingly simple.Except it's not that simple. This is where the virtual gear ratios come in. Like current Lexus hybrids, the system has ratios it can call up with the e-CVT. In this case, there are six virtual ratios to complement the four real physical ratios, for a total of 10 "gears" at the transmission's disposal. (Not coincidentally, the V8 LC 500 coupe has a 10-speed automatic.) One of the four fixed gears is always engaged when the car is moving, so the 10 ratios come about from combinations of what the e-CVT in front and the automatic in the back are doing. In other words, all 10 ratios are variations on the four fixed gear ratios, which means that all 10 gears could be considered virtual.It won't use all the gears all the time. In Eco mode, the car will start off on electric power and skip the first couple of "gears." When it's set to Sport or Sport +, the engine will be engaged from a stop and the transmission will select the lowest ratio. The sportier modes will also ignore the top couple of gear ratios.It can drive faster with the engine off. In a Lexus GS 450h with the Lexus Hybrid System, for example, at speeds above 62 mph or so the engine has to start up. This is because something needs to take up some slack from the battery-charging motor-generator or else it will start spinning too quickly.
