Lexus exploring PHEV, full EV and fuel cell versions of LS flagship

After four years of rumors about a Lexus LS powered by a hydrogen fuel cell, the chief engineer of the flagship sedan says the carmaker's working on even more options. Toshio Asahi told Australia's GoAuto that three alternative powertrains — plug-in hybrid, full electric, and hydrogen — are "all on the table" for consideration. Asahi wouldn't give any timeframes, but whenever they arrive, additional drive options would fill out the LS range to better contend with the Germans. Years of reports predicted this fifth-generation LS would get hydrogen power. A Motoring article at the end of 2014 forecast a fuel cell LS to arrive by 2017. In 2015 Japan's Nikkei newspaper reported that Lexus was considering a fuel cell option to arrive in 2020, around the time of the Tokyo Olympics. Later that year, at the Tokyo Motor Show, Lexus showed off the LF-FC concept, powered by a cell and stack arranged for "optimum front-rear weight distribution for a sporty saloon." GoAuto said that during that show, a Lexus executive said an FCEV powertrain would end up in production "sooner than you think." The following year, Autocar reported we'd see a production version of the LF-FC "on sale before 2020" as a replacement for the LS, and last year, Lexus trademarked the name "LF-FC Concept." The intel gets murkier regarding plug-in hybrid and full electric versions. We now know Lexus is working on a more powerful hybrid system. The current hybrid produces a total system 354 horsepower and 258 pound-feet of torque using the same 3.5-liter V6 in the standard car as a base, though the standard car adds two turbos for 415 hp and 442 lb-ft. The coming hybrid will likely use the twin-turbo setup and could achieve two important ends: Smoothing out noted issues of powertrain refinement, and at least matching the power specs of Mercedes-Benz and BMW flagship plug-in hybrids. That hybrid LS would still miss out on the all-electric driving of its rivals. If there really is an LF-FC coming in the next two years, it would seem a perfect time to retire the conventional hybrid and introduce a plug-in version embodying the velvet sophistication Lexus is known for. The battery electric LS is a big question mark outside of Lexus HQ. Last year Toyota announced a breakthrough in solid state battery technology, the carmaker announcing it wanted such batteries on the market by 2022.

Thanks to smaller engines, vehicle dependability falls for first time in 16 years

As automakers have made engines smaller and smaller to improve fuel economy, problems in those vehicles have gotten bigger and bigger. That's the synopsis of a J.D. Power vehicle-dependability study, which found that dependability dropped for the first time in 16 years, largely because the proliferation of four-cylinder engines is causing the vehicles to be less reliable. Specifically, the number of problems per 100 vehicles (or what J.D. Power calls PP100) during the past 12 months for 2011 model-year vehicles rose six percent from the year-earlier figures for 2010 model-year cars. Singling out four-cylinder vehicles revealed about a 10-percent increase in problems during the past year. This issues largely related to engine hesitation, rough transmission shifting and lack of power, signaling the inability of vehicle makers to iron out some of the problems in their smaller engines as they strove for better fuel economy. Six- and five-cylinder engines proved far more reliable. Among car brands, BMW's Mini sub-brand came out as least reliable, with 185 problems per 100 vehicles during the past year. Toyota's Lexus badge was easily the most reliable, with just 68 problems per 100 vehicles. Coming in second place was Mercedes-Benz. The overall average was 133. Check out J.D. Power's press release below. J.D. Power Reports: Increased Engine and Transmission Problems Contribute to Decline in Vehicle Dependability for The First Time in More Than 15 Years General Motors Company Receives Eight Segment Awards, While Toyota Motor Corporation Garners Seven and Honda Motor Company Earns Six WESTLAKE VILLAGE, Calif.: o Owners of 3-year-old vehicles (2011 model year) report more problems than did owners of 3-year-old vehicles last year, according to the J.D. Power 2014 U.S. Vehicle Dependability StudySM (VDS) released today. The study, now in its 25th year, examines problems experienced during the past 12 months by original owners of 2011 model-year vehicles. Overall dependability is determined by the number of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality. The study finds that overall vehicle dependability averages 133 PP100, a 6 percent increase in problems from 126 PP100 in 2013. This marks the first time since the 1998 study that the average number of problems has increased. "Until this year, we have seen a continual improvement in vehicle dependability," said David Sargent, vice president of global automotive at J.D.

Lexus flagship SUV, a true three-row crossover and an EV on the way, dealer says

Lexus is working to update its mostly dormant portfolio with new cars to populate currently unfilled segments. These will include a full electric vehicle, a true three-row crossover, and a flagship SUV. Many existing models will be getting updates as well, along with a new infotainment system. The agenda was outlined by the chairman of the Lexus National Dealer Advisory Council, John Iacono, in an interview with Automotive News. It very much reads like someone trying to show how much they know by spilling the beans on random bits of info they've heard (it's definitely not anything approaching official information from a company executive), so we'll take most of it with a fistfull of salt. Still, there's plenty here that certainly makes sense given the state of the current Lexus lineup.  Iacono says that Lexus has not been quick enough to fill new segments in the last two years. It was "only the service that kept people coming back," he says. Customers turned elsewhere because they couldn't find what they wanted in the Lexus lineup, even though the cars are "bulletproof." What those customers wanted, he says, included a three-row crossover. A couple of year ago, dealers rejoiced when the RX was stretched to accommodate a third row (pictured below), but it was only a stopgap to keep dealers happy. Iacono said this people-mover will arrive "relatively soon," likely referring to the luxury crossover set to be introduced this year. Lexus doesn't want to deviate from RX's philosophy because it's the brand's most successful product. Lexus does sell two other three-row vehicles, but the GX and LX are traditional body-on-frame SUVs derived from off-road-oriented Toyotas.  View 20 Photos Speaking of the LX, Lexus will soon be producing an SUV that Iacono believes will become the marque's flagship. The halo car crown will no longer be worn by the luxurious LS sedan or flashy LC grand tourer coupe. Instead, Iacono described this SUV as a niche off-roader that won't sell at high volumes, but will serve as a must-have item that makes the brand cool. To us, that sounds a lot like the previously reported Lexus-badged version of the next-generation Land Cruiser. Curiously, Iacono later refers to upcoming refreshes of the GX and LX, so perhaps the new flag-bearer will be called something else. Or, again, perhaps the chairman of the Lexus National Dealer Advisory Council just doesn't know as much as he lets on in this lengthy interview.
