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.

2019 Infiniti QX50 vs. compact luxury SUV rivals: How they compare

With apologies to the EX35, or whatever it was eventually renamed, Infiniti has been without a proper, competitive entry in the compact luxury SUV segment. You know, the segment that's growing faster in sales and entries than any other? To say the 2019 Infiniti QX50 is long awaited would therefore be an understatement. At first glance and drive, the new QX50 would indeed seem to be wildly more competitive than its predecessor, which come to think of it, was eventually called the QX50 as well. This one is based on an all-new front-wheel-drive platform, and although it lacks the inherent verve of the old, rear-drive- and 370Z-based one, the resulting increase in cabin space should be a welcome tradeoff. In fact, as you'll see below, the QX50 has gone from one of the smallest compact SUVs to the most spacious. How does it stack up in every other way? Say, against the segment's four best-selling entries last year: the 2018 Lexus NX 300, 2018 Acura RDX, 2018 Audi Q5 and 2018 BMW X3. On paper at least, really well as it turns out. Let's go to the spreadsheet! Discover and compare other luxury crossovers with our Car Finder and Compare tools. Comparing engines, drivetrains and transmissions With the exception of the Acura, all of the contenders come with 2.0-liter turbocharged four-cylinder engines. As you can see, the Infiniti is the heavyweight amongst the four-bangers, boasting the most horsepower and torque. The Acura V6 nips it by 11 hp, but the QX50 is still the overall torque champ. Plus, as we documented in the QX50 first drive, the Infiniti's new VC-Turbo engine is also the most technologically advanced. The Lexus is the wimp of the group and is also the second-heaviest, which isn't exactly the ideal scenario. The Infiniti is the only one in the group to feature a continuously variable transmission. That's not going to generate much applause around here. The BMW tops the gear count with eight, while the Audi is the only entry with a dual-clutch automated manual. The Acura and Lexus have only six gears, but they're good transmissions and it's not like their fuel economy is off the pace. The Audi and BMW come standard with all-wheel drive, while the others offer a choice of front- or all-wheel drive. Comparing cargo and interior space The new front-wheel-drive platform is paying dividends inside for the 2019 QX50, as it now boasts the most maximum cargo space at 65.1 cubic feet.

2018 Lexus LS First Drive | Luxury, performance and the puzzling parts

When one imagines the enormous executive sedan that might be driven by a wealthy lawyer or banker (or their chauffeur), the mind naturally goes to the Mercedes S-Class or the BMW 7-Series. Venerable, enormous and expensive. But for those wanting to keep their driveway a little more understated, we also have the Lexus LS. Sure, it's not as ostentatious as the big saloons from Munich and Stuttgart, but it has a dignified elegance all its own. For nearly three decades, the LS has been a discrete and dependable Japanese luxury sedan. The new 2018 LS, perhaps thankfully, is a bit less discrete. We saw the new-look LS when it was introduced earlier this year in Detroit. Now we know how it drives. We put the 2018 LS through its paces on the traffic-clogged streets of San Francisco and over the Golden Gate Bridge to the twisty B-roads around Marin County and the legendary Skywalker Ranch, where we stopped for lunch. Unfortunately, all in attendance were sworn to secrecy about the details of Skywalker Ranch, but we're free to tell you all about the LS. Here's our one-sentence summary, which can be used to describe many cars to bear the Lexus badge: It's excellent in many respects, odd in a few, and incredibly, massively frustrating in one very important area. Lexus has a brand new 3.5-liter twin-turbocharged V6 paired with a 10-speed automatic transmission, a first for a premium passenger car. It produces 416 horsepower and 442 pound-feet of torque, up from 386 hp and 367 lb-ft from the outgoing naturally aspirated 4.6-liter V8. Lexus engineers are extremely proud of the fuel efficiency of the new engine, which required some clever technical innovations (a longer bore stroke and increased valve angle) as well as tech borrowed from Formula One, including a "laser clad valve seat" that allows for a more direct flow of air into the combustion chamber and a high "tumble ratio." In other words, Lexus figured out how to get more bang out of each gasoline-powered buck. Fuel economy numbers are 19 city, 29 highway, and 23 combined for the RWD version and 18/27/21 for AWD, with the highway numbers particularly helped along by the 10-speed gearbox. It's a torque converter unit, but Lexus promises shift times that rival its dual-clutch-wielding competitors. The LS is no slouch, either. In RWD trim, the nearly 5,000-pound car hustles from 0-60 mph in 4.6 seconds, according to Lexus' reckoning.
