Lexus LS may get plug-in hybrid, EV, and hydrogen fuel cell variants

As automakers continue envisioning a future for alternative propulsion to rid the world of the classic internal combustion engine, some are doubling down on their efforts to make this vision a reality in the name of innovation. Some are taking an even more aggressive approach by doing away completely with the gas engine entirely in the name of electrification.

But others are looking for a more progressive transition into electrification by blending the best of both worlds with hybrid powertrains. One of those automakers, Lexus, recently launched its latest and greatest LS flagship in Australia, and Australian auto outlet GoAuto.com heard the newest model has some new powertrains under development in the pipeline.

Speaking with the Lexus LS’s chief engineer Toshio Asahi at the regional media launch, GoAuto.com learned that Lexus is currently working on a plug-in hybrid variant, a full-electric, and even a hydrogen fuel-cell. When the latest LS was undergoing planning and R&D, Asahi said all of those variants were immediately brought to the table for discussion and are still being considered.

Of course, Asahi wasn’t very specific with details of future models, as is the typical candid response from most manufacturers. But it still is a far cry from a flat-out “no,” and leaves potential for future variants of the LS. He acknowledged that the company is aware of its direct rivals from Europe are doing.

Given that electrification is the latest trending strategy from automakers — but battery technology and lacking infrastructure continue to inhibit its growth — some car manufacturers are instead trying to ease customers into the transition toward electrification.

As of now, the best solution is the hybrid powertrain — part electric and part gas-powered. Because combines the best of both worlds without incurring the impractical quirks of all-electric vehicles, we’re expecting a huge influx of hybrids and plug-in hybrids in the near future to meet most people’s needs. All-electric versions will also surface for the EV fans, and those who like to keep things traditional can opt for the base gas-only V6 model. Fans of even more futurist tech will also be interested in a hydrogen fuel cell model, which is also a promising prospect for alternative propulsion.

At launch for us stateside, the 2018 Lexus LS flagship sedan comes with the choice of a gas-only six-cylinder beginning with the LS500, featuring an all-new twin-turbocharged V6, a first for Lexus. Displacing 3.5-liters, it churns out an impressive 416 horsepower and 442 pound-feet of twist, to either the rear wheels or all-four through a new 10-speed automatic.

In keeping with tradition from the previous models, there is a hybrid variant, called the LS 500h. It takes the same, new Multistage Hybrid System from the hot LC 500h coupe, and stuffs it into the LS. It features dual-electric motors with an Atkinson-cycle 3.5-liter V6 for a total of 354 horsepower. Juice is supplied by a lithium-ion battery pack.

Mercedes-Benz G580 first drive: old-school off-roader goes electric
2025 Mercedes-Benz G580 from three quarter view.

American car buyers mostly know Mercedes-Benz as a luxury brand. But for decades, the automaker has also produced the tough, rugged G-Class (also known as the Geländewagen or G-Wagen), an SUV not afraid to get its leather upholstery muddy. And now, this iconic Mercedes is going electric.

The 2025 Mercedes-Benz G580 with EQ Technology — the final name of the SUV previously known as the EQG — isn’t the first electric off-roader. The Rivian R1S and R1T and GMC Hummer EV have proven that electric powertrains and off-roading are a great combination. But the electric G-Wagen is different because it’s based on an internal-combustion model — and a very traditional one at that.

Honda believes hydrogen semi trucks will make the case for fuel cells
Honda hydrogen fuel-cell semi truck.

Honda remains committed to hydrogen fuel-cell vehicles, but the market for those vehicles remains limited. So Honda is looking at other uses for fuel cells -- including commercial trucks.

To show how that could work, Honda converted a semi truck to fuel-cell power, replacing its diesel engine with three fuel-cell modules. Together, the three modules produce a combined 321 horsepower, and can propel the truck to a top speed of 70 mph. There's enough onboard hydrogen storage capacity for a 400-mile range with a full load, Honda claims.

Mercedes-Benz G580 vs Rivian R2: Is the much cheaper Rivian actually better?
2025 Mercedes-Benz G580 from three quarter view.

Mercedes-Benz has finally taken the wraps off of the new "Mercedes-Benz G580 with EQ Technology." Yeah, it's a mouthful, but it's basically a new electric G-Wagon. It looks a lot like the G-Wagon you know and love, but with an electric powertrain and a battery. It's not the only electric SUV out there, however, and there are some great ones -- like the Rivian R2.

Both the Mercedes G580 and the Rivian R2 have a lot going for them, but they also approach the electric SUV slightly differently. Is one better than the other? I put the two head-to-head to find out.

The approach that the two vehicles take to design is quite different -- and you might like one better than the other.
