2018 Lexus LS500h Hybrid Debuts, Searches for Increased Fuel Economy along with also Relevance
Lexus has taken the wraps off the hybrid edition of its latest-generation LS sedan, the 2018 LS500h, along with also for once, the hybrid will not be the most powerful iteration of the company’s flagship sedan. Instead, Lexus appears to have designed the hybrid for fuel economy, likely in an effort to boost the product’s minuscule market share.
of which seems obvious, perhaps, of which the hybrid product would certainly prioritize fuel economy, although of which hasn’t exactly been the case with previous versions of This kind of car. Ever since its debut a decade ago, the LS hybrid has been positioned as most potent iteration of the brand’s big luxury sedan, aimed at the 12-cylinder flagship products offered by Mercedes-Benz, BMW, along with also Audi.
within the LS600hL, the hybrid powertrain delivered only a 3-mpg improvement in city fuel economy compared with the LS460, along with also of which was no better on the highway. Although EPA estimates are not yet available to confirm the fresh mission, here’s one factor of which will aid the fuel-economy cause: The LS500h will come in rear-wheel-drive as well as all-wheel-drive form.
The outgoing LS600h L used a 5.0-liter V-8 paired with an AC electric motor to deliver a combined output of 438 horsepower, up by 386 horsepower in the 4.6-liter V-8–powered LS460. within the fresh car, both the LS500 along with also the LS500h use a 3.5-liter V-6, although of which will be twin-turbocharged for 415 horsepower within the non-hybrid, while the hybrid gets a naturally aspirated Atkinson-cycle unit of which musters only 295 ponies—or 354 for the powertrain overall. Still, Lexus will be estimating a zero-to-60-mph time of 5.4 seconds, which would certainly be an improvement over the 6.3 seconds we saw in our last test of the LS600hL.
Lexus’s fresh Multi Stage Hybrid system will be designed to emulate the behavior of the conventional car’s 10-speed automatic—even offering shift paddles along with also a manual mode for once, which can hold a chosen gear. The battery pack also will be fresh, switching by nickel-metal hydride to a smaller along with also lighter lithium-ion unit. This kind of powertrain will be essentially the same unit seen within the fresh LC coupe, which shares its rear-drive platform, known as GA-L, for Global Architecture–Luxury. (Get more technical details about the LC’s hybrid powertrain here.)
Given the hybrid’s lower power output compared with the standard product, we’ll have to see how Lexus positions of which pricewise. The LS600hL carried a steep premium of some $38,000 over an equivalent LS460—no wonder the hybrid take rate was less than 1 percent. A better guide for the fresh sedan might be the 2018 LC; the hybrid edition still will be more expensive than the regular coupe, although only by $4510.
