2014 Lexus IS350 F-Sport

Is A New Kind Of Lexus Hiding Under That Radical Skin?
When the now-outgoing Lexus IS generation was launched back in 2006, the company would not have been wise to bring the compact luxury sedan to be driven by journalists to a track like Driveway Austin Motorsports. Taking along a BMW 335i for comparison loops would have proved an ill choice as well.
Our own Jonathon Ramsey found the current-generation Lexus IS250 to be fairly nimble over a tightly wound autocross course, when he drove it back-to-back with the prototype version of this 2014 IS a few months ago. Our track for testing the fully realized version of the IS350 F-Sport meanwhile - again with the 2013 version along for competitive driving - was on a circuit designed to string together recreations of some of the best tracks in the world. Laguna Seca, bits of the Nürburgring and sections inspired by Imola and Ferrari's Fiorano test track all make for a far more enticing road course than you'd expect to find plunked down in a nondescript area a few miles east of downtown Austin. Critically, this environment highlighted what strides Lexus has made in the sport sedan race with its new IS.

'Next Lexus F' teased ahead of Detroit debut

We've got absolutely zero actual information from the automaker on what its "Next Lexus F" will be, other than what was just released today in this brief press release and lone teaser image, but our best guess is that it's the next-generation IS-F sedan. The timing would make sense, considering that the latest IS just hit the market earlier this year as a 2014 model.
Since we know so little, we'll just share some of the exuberant marketing speak contained in the press release for your reading pleasure:
Designed from the asphalt up, to strike at the heart, the newest Lexus F model will debut at the January 2014 North American International Auto Show in Detroit.

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.
