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.

Here are this year's top 5 automaker April Fools’ jokes

April 1 is the wonderful day when PR departments really push themselves to top the zany jokes they came up with the previous year. And it's not just fast-food chains competing with each other, or breweries announcing they have released stuff like a fermented herring flavored beer: carmakers' media teams rarely miss out on the opportunity to play a little joke on their audience. Here are a few of our favorites from this year:1) Porsche Porsche announced that it's launching a Mission E tractor, styled to resemble its 1950s tractor models. "With a power output in excess of 700hp, the Mission E Tractor will be the fastest accelerating agricultural vehicle in the world, enabling farmers to harvest crops in record time with the added environmental benefits of zero emissions at source and significantly reduced operating noise."2) Lexus Lexus actually jumped the gun, telling us on March 28 that it's combining cars and drivers using DNA matching. The kicker was that with DNA-matched cars, owners would be able to start their Lexuses by licking the steering wheel.3) McLaren Automotive McLaren said it's boosting efficiency by quite eccentric measures, such as measuring the technology center's lake and floor tiles daily, and by synchronizing the staff's tea breaks.4) BMW Motorrad BMW's motorcycle arm is solving parts availability issues in remote locations by offering a 3D printer mounted permanently on the bike's rack: If you need to replace a broken-off gear lever, you can just print one. "The new system will mean that even very rarely required parts not generally stocked by BMW Motorrad sales partners can be supplied on a just-in-time basis." BMW even went to the lengths of announcing that the "BMW Motorrad iPart 3D Mobile Printer" was tested on the Antarctic, by erecting a tent whose poles were produced onsite.5) Honda Last but not least, Honda UK purportedly cut the roof off a new CR-V, calling it the CR-V Roadster. Tellingly, no convertible top was even offered for the concept, "making it a no-top rather than a drop-top. This innovative design makes it a vehicle purely for sunnier climates and therefore completely useless for the two-day British summer which traditionally occurs in May."Related Video: Featured Gallery Top 5 April Fools 2018 Image Credit: Porsche Green Humor Weird Car News BMW Honda Lexus McLaren Porsche bmw motorrad mclaren automotive

2017 Lexus Model Year Preview and Updates

As the market for luxury and near-luxury vehicles continues to expand, Lexus intends to grow its already-dominant share; new entries and updates to existing models reflect that. Biggest news for this calendar year – if not the 2017 model year – is unquestionably the introduction of the 2018 LC 500 - pictured above - and LC 500h, high-performance 2+2 coupes powered by either a blazing 5.0-liter normally aspirated V8 (LC 500) or full-hybrid system (LC 500h). Complementing their spring intro is the arrival of a redesigned LS 500 sedan, also making its debut as a 2018 later in this calendar year. LEXUS CT 200h: Lexus' hybrid hatch, nearly invisible from a marketing standpoint, receives new colors in 2017: Atomic Silver Caviar, Autumn Shiver and Blue Vortex Metallic. ES: The various ES trims, including the hybrid, incorporate the Lexus Safety System+ as standard equipment. Display Audio adds the Scout GPS link and all trims receive rain-sensing wipers. GS: Lexus' 5 Series weapon, sold in four variants – 200t, GS 350, GS 350 AWD and GS 450h – incorporates the Lexus Safety System+ as standard, offers a limited-slip differential option for the GS 350 RWD and supplies navigation on the 200t free of charge. IS: The compact Lexus four door receives an in-your-face refresh. A new front fascia, headlamps and wheel designs constitute the significant updates. Inside, the infotainment screen is enlarged, and the Lexus Safety System+ is made standard. LC: Lexus' 2+2 halo is all-new, and comes in two variants: LC 500 is V8-powered, while the LC 500h is equipped with a V6 and fully hybrid integration. The coupe is in Lexus showrooms by May, 2017. LS: The 2017 LS drove into the model year with minimal changes. The big news is the introduction of an all-new 2018 LS in the fourth quarter of this year. RC: Lexus' four-place coupe receives new wheel finishes on both 18-and-19-inch wheels, as well as available triple-beam LED headlamps. In the RC 350 performance dampers are made standard, and in all models the Display Audio receives a Scout GPS link. GX: Little substantive news for the Lexus GX SUV, but heated/ventilated front seats are available as a standalone option, and second-row captain's chairs are standard on the Luxury trim and available on Premium. Finally, the GX receives an optional Sport Design Package, a set of cosmetic upgrades targeting those with a taste for urban adventure.
