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.

Construction of Lexus' first US assembly line underway

The ES is Lexus' top-selling sedan, but the Japanese luxury marque has never manufactured it outside of Japan. In fact, Lexus has never made any cars in the United States, one of its largest markets worldwide. But that's about to change.
Yesterday, construction began in Georgetown, Kentucky, on the first Lexus assembly line in America, the first concrete (or steel) step in a $360-million expansion of Toyota's plant in the Bluegrass state that will create 750 new jobs. The expansion was announced last April by chief executive Akio Toyoda at the New York Auto Show.
Once the new assembly line gets online in the fall of next year, Toyota plans on building some 50,000 units of the ES each year. Lexus sold a record 72,581 examples of the ES in the United States last year - 30 percent more than the previous year - so Lexus will either have to import some more from overseas or leave some buyers disappointed.

Lexus LF-CC gets green light, Evoque rival under consideration

While wandering the floor at this week's LA Auto Show, we had a bit of an epiphany at the Lexus stand. The traditionally stodgy Toyota premium outlet is really starting to come into its own in terms of exciting design. And not just with production models like the excellent new GS sedan. At the front of the display, a triangular formation of plinths was a feast for the eyes - the head was formed by the LFA Nurburgring Package supercar, flanked on either side by the company's outré LF-LC and LF-CC concept cars.
So consider it welcome news on our end that the LF-CC concept shown above has apparently been given the production green light, with a projected arrival by 2015. So says Autocar, which quotes an unnamed source at Lexus willing to confirm that a senior engineer has been tasked with the project. The British publication suggests that the production version of the 2012 Paris Motor Show star will probably be built in both coupe and convertible formats and ride atop the automaker's new modular rear-wheel drive architecture. Power is expected to be an evolution of the GS 350h's hybrid drivetrain.
In other news, that same shadowy source at Lexus has reportedly confirmed that the Japanese luxury brand is "seriously studying" offering a small SUV in the mold of the stylish Range Rover Evoque from Land Rover, though no further details are given. Lexus' own RX crossover range has long been a massive hit for the brand, leaving many industry analysts scratching their heads as to why the automaker hasn't already expanded its crossover offerings to include both larger and smaller formats.
