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.

2020 Lexus GS F Review & Video | Looking past the numbers

You don't hear much about the 2020 Lexus GS F. It's been out for a while now, the model having debuted for 2016 and the base GS sedan stretching all the way back to 2012. That's an awful lot of time for the automotive world to whiz by, especially in the upper echelon of performance sedans. Packing 467 horsepower is suddenly weak sauce when rivals have crested the 600-hp plateau. The fact that Lexus still hasn't convinced the automotive enthusiast community at large that it actually makes compelling performance machines certainly doesn't help.  To be perfectly honest, I have avoided testing the GS F for several years now. "Who's going to buy that?" I've pondered, considering all of the above plus its $85,000 price tag. Nevertheless, I've got more time on my hands these days to test more cars and a Lexus Flare Yellow paint job is impossible to ignore, so hey, why not? Well, after a week, I didn't want to turn over the keys. When faced with first-world automotive journalist problem of picking between the the Flare Yellow GS F and the BMW M340i also parked out front, I quickly chose the Lexus. And if I had $85,000 to spend on a high-powered luxury sedan, I honestly think I'd happily choose it over the Germans that outdo it on paper. Many of you will think that stupid and will point to the numbers at hand. The GS F's 5.0-liter V8 sends 467 hp and 389 pound-feet of torque to the rear wheels only, and is capable of a 0-60 run of 4.5 seconds. A BMW M5 has 600 hp and hits 60 in 3.2 seconds; the lesser M550i has 523 hp and a 3.6-second time. That M340i xDrive also in my driveway? It hits 60 in 4.1. Over at Mercedes-AMG, the E 63 has 603 hp and a 3.3-second time. Only the lesser E 53 is comparable to the Lexus with 429 hp and a 4.4-second 0-60 time. Its torque is also comparable, unlike the rest of those Germanic monsters that utterly roast the Lexus. However, all of that extra output and all of those quicker times are also indicative of the very reason the GS F remains so desirable. It doesn't have a turbocharger, ensuring unencumbered response, a zesty 7,800-rpm redline and marvelous noises that don't require the sound enhancement feature Lexus throws in anyway (and that I turned off). It also doesn't require all-wheel drive to quell elephantine gobs of tire-shredding turbocharged torque, thereby letting the front wheels simply handle the steering. The rears, meanwhile, can smoke away and swing loose should you disable the appropriate settings to do so.

New Toyota Supra may get a twin-turbo Lexus V6

We've heard endless rumors that a successor to the much loved and much missed Toyota Supra is in the works. Toyota hasn't done much to deny these conversations. On the contrary, the FT-1 concept from two years ago and the partnership with BMW have only fueled the fire. Now, talk of a new Lexus engine has led to speculation about the supposed Supra's powertrain. To be clear, this is mostly heresay. Few things have actually been confirmed, but based on what we know a few conclusions can be drawn. We know that BMW and Toyota are working on a joint product. We've seen mules testing out in the wild. In BMW guise, the possibly Austrian-built car will more than likely powered by turbocharged inline four and six-cylinder engines. Unless Toyota wants to use Bimmer power, they'll need to shoehorn one of their own under the hood. That leads us to this rumor of a twin-turbocharged V6 that will presumably power the new Lexus GS and LS. Japanese automotive publication Mag-X first reported on this engine. It was then picked up by YouWheel and Car Keys. Mag-X cites Toyota insiders and even gives an engine code, 943F. This engine allegedly will make more than 400 horsepower and more than 300 lb-ft of torque. While unconfirmed, this makes sense for Lexus. Nearly every luxury competitor has a six-cylinder engine with forced induction. While Toyota has previously had turbocharged inline-sixes, they've never produced a factory turbo V6. Every automaker is downsizing engines in an effort to meet fuel economy and emissions regulations. Toyota and Lexus will follow suit. Taking that V6 and tuning it for a performance application is a solid, if unverified, possibility. Related Video:
