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.

2018 Autoblog Technology of the Year finalists

After months of prepping and several days of testing, we narrowed the field for Autoblog's 2018 Tech of the Year award to the Nissan Rogue with ProPilot Assist semi-autonomous driving system, the Lexus LC 500h and its new hybrid powertrain, and the Chevy Colorado ZR2 and its trick Multimatic spool-valve off-road shocks. Three very different cars with very different technologies duking it out for the award. Look for news of our winner at the 2018 Detroit Auto Show. We hand out this award every year to the technology or feature that we feel moves the bar forward for the automotive industry. Read more here on how our testing process works. We discuss, debate and count up score sheets, judging each vehicle and technology on a few different criteria. Is its purpose noteworthy? Does it work well? Does it advance the industry? The Nissan Rogue with ProPilot Assist was actually a prototype, as the technology will first debut in the 2018 Nissan Leaf. Still, we're here to test the tech and not the car. ProPilot Assist combines adaptive cruise control system combined with lane-keeping assistance. The system uses sonar, radar and a number of cameras for some light semi-autonomous driving and enhanced safety. While these systems aren't new individually, Nissan's system is affordable, intuitive, and coming to a mainstream product — democratizing the tech in a novel way, if you will. That's why it's here. The Lexus LC 500h uses a new powertrain that Lexus has dubbed the Multi-Stage Hybrid System. Basically it combines two types of transmissions — a CVT and a four-speed automatic — in a single unit mated to a naturally aspirated V6. That's complex and unorthodox technology, and Lexus engineered it to give drivers the efficiency of a CVT without sacrificing driving enjoyment. The package is subtle, working in the background to create a nearly seamless driving experience. It's engaging in a way most other hybrids can only dream of. The fact that it's wrapped in such gorgeous sheetmetal only makes things better. The Multimatic spool valve shocks in the Chevy Colorado ZR2 might seem low-tech compared to ProPilot Assist and the Lexus Multi-Stage Hybrid, but they represent a completely novel application of a technology that several years ago was so expensive that it was reserved for top-tier race cars. Like the LC 500h, these shocks really change your perception of how a vehicle like this should drive.

2014 Lexus IS brings boldest design yet to entry-level luxury

Lexus is evidently dead serious about removing some of the starch from its collar, as evidenced by the boldly styled new IS sedan just unveiled here at the Detroit Auto Show. We didn't know what to make of Lexus' entry-level sport sedan when we first saw images of it earlier this week. Dominated by the gaping maw of a spindle grille and flanked by headlamps with Nike swoosh daytime running lamps, the photos showed a distinctive (if not completely cohesive) design. Having now seen the design in the metal, we have to admit it comes together better than it does on screen.
The new model will feature both rear- and all-wheel drive models in both 2.5-liter V6 (IS250) and 3.5-liter V6 (IS350) trims. Lexus also showed an IS300h hybrid model at the reveal, but it is earmarked for Lexus' home market of Japan, along with Europe and other markets. No word yet on why the model probably won't be sold here in North America, but our AutoblogGreen compatriots are looking into it.
Aside from its bold new look front and rear, the IS carries forward a lot of the ideas seen in other newer Lexus models, namely the GS. Hidden beneath the IS' sheetmetal is the multilink rear suspension from the GS, along with its electric power steering setup. The new IS rides atop a three-inch longer wheelbase for better rear seat room, but during our brief time sitting in the car at the press conference melee, it still didn't feel terribly roomy (it rarely does in this class). At least the seatbacks fold 60/40 for the first time for additional utility.
