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.

2022 Lexus IS 500 F Sport First Drive | A charismatic outlier

For 2022, the Lexus IS is getting a V8, the first time since the last IS F was built back in 2014. But instead of an uncompromisingly sporty successor to the IS F, Lexus has created something a little softer and more civilized, and given it a similarly watered-down name: IS 500 F Sport. And in our time with the sedan, it's an apt name, since it's not a real competitor for the M, AMG, RS and Blackwings of the world. But what it is isn't bad, either. It's a characterful sport sedan that makes for an interesting alternative to similarly softer and more civilized choices like the BMW M340i or Audi S4. It is hampered by some familiar Lexus problems, but it has enough to like that the right buyer can happily overlook the shortcomings. Before diving too deep into the driving impressions, let's go over what was done to create the 2022 Lexus IS 500 F Sport. The lynchpin is the 5.0-liter naturally aspirated V8. It's a unique feature for a class full of turbocharged four- and six-cylinder engines. It sends 472 horsepower and 395 pound-feet of torque to the rear through an eight-speed automatic transmission and a standard limited-slip differential. Lexus clocks the 0-60 time at 4.4 seconds, which is on par with the rear-drive M340i. Of course, the BMW has 90 fewer horsepower. It sits on a sport-tuned adaptive suspension and gets bigger brakes with better cooling, but that's about it for mechanical upgrades. It's all wrapped in a body that looks almost exactly like the IS 350 F Sport except for the quad exhaust, exclusive Enkei wheels and the power bulge that raises the hood by 2 inches. It's great for keeping a low profile, but nodding quietly to those in the know that, yes, this is the fast one. The interior also gets leather and faux suede upholstery, a thick F Sport steering wheel and other F-related trimmings. As with every Lexus so equipped, the IS 500's V8 is a true treat that makes up for whatever disadvantages it might have on paper with endless character in person. It's spectacularly smooth and demure most of the time, but when asked, it delivers a raucous intake growl and a just right amount of exhaust noise. And it does so without needing to have the artificial sound enhancer turned on (it's adjustable from nothing to 100% via a scroll wheel on the dash). It's eager to rev and will do so to a little past 7,000 rpm. Peak power lives up there, but it has enough mid-range grunt to keep it entertaining even when you're not making the most of every gear.

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events." View 33 Photos So we asked Sage Marie, Senior Manager of Public Relations for Honda and Acura. "If the car is stock, the warranty covers it on a track just as it does on the street. No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.
