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.

Lexus GS F points its gaping grille at the BMW M5

A mere trio of weeks after the latest report in the slow-moving Lexus GS F rumor cycle, we have a brand new batch of spy photos of the BMW M5-fighting sedan. Looking more and more production ready - notice the more finished exhausts compared to our last round of photos - the GS F can be seen poking around what we imagine is Germany.
If the RC and RC F Coupes are any indication, it looks like Lexus will start fitting its high-performance models with a new, single-frame version of the spindle grille while a dual-frame grille will be reserved for lesser trims. Backing up that suspicion is the new single-frame grille found on this prototype, marking the first time the suspected F line styling piece has been seen on a GS F prototype.
The aforementioned staggered quad exhausts look good on the GS' rear end, while a none-too-subtle rear spoiler ups the rear's visual flair. The low-profile rubber and the multi-spoke, black wheels are nice touches that work well with the front fascia features, in addition to the new, camo'd grille and substantial brake cooling ducts.

2015 Lexus LS gets tighter turning radius, new infotainment

Go back a couple of decades and the thought of a Japanese automaker challenging the German limousines would have seemed laughable, but 25 years later the Lexus LS is a mainstay of the luxury sedan market. And it didn't get there by sitting on its laurels, so it should come as little surprise that Lexus is offering some small tweaks as it enters the 2015 model year.
This time around the upgrades are rather minor, consisting primarily of a new multimedia system. It's got an updated navigation system with 12.3-inch display, revised backup camera imagery with dynamic gridlines, and an enhanced Lexus Enform App Suite that can control the locks, ignition, climate control and more, remotely.
While they were at it, Toyota's engineers also reduced the turning circle by four inches (on cars fitted with 18-inch wheels), and enhanced the F Sport package as well. Otherwise, it's essentially the same LS we've always known.
