Jaguar solution to keyless start could save lives

UPDATED: An earlier version of this story indicated the Jaguar keyless start function was meant as a safety feature, when in fact, it is meant as a convenience one and will not work as described if automatic stop/start is not engaged. Today, The New York Times published an article about more than two dozen deaths related to drivers accidentally leaving their cars running, closing their garages and later succumbing to carbon monoxide that flooded their homes. The reason has been identified as "keyless start" features, or proximity entry and push-button start, where owners don't need to physically handle a key or fob to gain entry into the vehicle or start it. It is the latest, and deadliest, issue raised with this system after those related to security and simple inconvenience (for instance, leaving the car at a valet or car wash with the fob in your pocket). From my personal perspective, The New York Times had a rather harsh "evil carmakers" tone throughout the article. This is not a matter of a known faulty component, as with the GM ignition switch recall. This has as much to do with user error where people leave their car without pressing the "off" button and without noticing the engine is still running. About half of the cars in question are produced by Toyota and Lexus, brands that have offered keyless start longer than most. They are also brands with high rates of elderly owners, who seemingly made up a majority of reported deaths and injuries. One fire department in Florida even started a campaign alerting those in the area of the dangers of leaving your car running when it noticed a correlation between an increase in cars equipped with keyless start and calls related to carbon monoxide poisoning. I see several contributing issues at play, most of which go well beyond this particular issue. First is insufficient training of owners by dealers and/or owners not paying close enough attention during this training. Cars are complicated, but you should at least know how basic functions work. Second, woefully inadequate driver training in this country. Third, and with apologies to the AARP, insufficient testing of elderly drivers and/or insufficiently low standards for elderly drivers. If you don't know you have to shut the car off or cannot hear that an engine is running, perhaps you shouldn't be driving. Fourth, re-examining keyless start systems.

The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.

Lexus LC convertible could appear in 18 months, LC F to follow

Auto Express reports that Lexus has a approved a convertible version of the LC, and is close to green-lighting a high-performance LC F trim. The Detroit Bureau reported that the same two models were in development one year ago, citing Lexus sources at the Detroit Auto Show who told the outlet "a number of additional variants" would follow the coupe's launch. The timeline's been stretched a bit between then and now; instead of getting the convertible this year, Auto Express says the "done deal" droptop should arrive in 18 months to two years. It's harder to read what we might get in an LC F. Gossip is that the naturally aspirated, 467-horsepower, 5.0-liter V8 wouldn't be the right motor for a hot LC. That V8 serves in lower-tier F models. so word is that Lexus engineers are considering a 4.0-liter, twin-turbo V8 with around 600 hp. Lexus chose the BMW 650i, Mercedes-Benz S-class coupe, and Jaguar F-Type as competitors to the LC, all of which have convertibles and high-performance trims. Among the specially-tuned challengers, the Jaguar F-Type R comes in with the lowest power figure at 550 hp. Both models would return Lexus to a small, exclusive end of the market where it hasn't held a membership since 2010. Rejoining that soiree — a party hosted by the Germans, because these matters always come back to the Germans — is another huge, and costly, step toward shedding Lexus' somnolent image. Akio Toyoda said the goal for his luxury arm was "that the words 'Lexus' and 'boring' never appear in the same sentence again." A three-model lineup would give the LC a genuine chance to contribute to that aim.
