The Latest Lexus LS, Longer, Lower, Wider & More Exciting

Longer and lower than the sedan it replaces, the all-new LS debuts a strikingly bold design with a coupe-like silhouette punctuated by the Lexus design language. A new driver-centric performance feel comes from building the LS on the company’s all-new global architecture for luxury vehicles (GA-L). This premium rear-wheel drive platform, an extended version of the one used for the stunning new Lexus LC 500 coupe, will offer a more dynamic experience on the road while further elevating renowned Lexus comfort.

The original Lexus LS won acclaim by anticipating what luxury customers would want, rather than simply amplifying what established luxury automobile brands offered at the time. In that spirit, the 2018 LS sedan’s spacious cabin, unique appointments and visionary technology will once again surprise customers by resetting expectations for a global flagship sedan.

“We set previously unheard of targets and resolutely pushed ahead towards these ambitious goals,” said LS chief engineer, Asahi. “The customers who are going to want to own a Lexus flagship are already surrounded by luxury on a daily basis, people who have a sharp eye for authenticity to begin with. We wouldn’t turn their heads with a conventional premium product.”

A Flagship Reborn

Just as the original LS launched the Lexus brand, the all-new 2018 LS continues the brand’s more dynamic direction. Each generation of LS sedans leading up to this iteration advanced luxury, craftsmanship, performance and safety in their own way, with the most recent also introducing a far more emotional design and engaging on-road performance.

To create the all-new LS, Lexus took the approach of starting from new, reimagining what a flagship sedan should be, as if launching the brand all over again. The goal was not to improve on what Lexus has done, but to exceed expectations of global luxury customers.

A common thread going through all LS models remains: Omotenashi, the concept of Japanese hospitality. Applied to a luxury automobile, it means taking care of the driver and passengers, anticipating their needs, attending to their comfort and helping to protect them from hazards.

LS Performance and Smoothness Redefined: Twin-Turbo V6 and 10-Speed Transmission

For both high power and excellent fuel efficiency, Lexus designed an all-new 3.5-liter V6 engine specifically for the new LS with all-new twin turbos developed through the company’s F1 technology. This new engine in the LS is indicative of the more dynamic approach being taken by Lexus, offering V8-level power without sacrificing fuel economy-all while minimizing noise and vibration. The new LS engine offers the output one would expect in a flagship sedan: 415 horsepower and 442 lb-ft of torque, sizeable gains over the current LS model’s V8. The long stroke and optimized stroke-to-bore ratio contribute to high-speed combustion and the efficiency of the twin turbos, which assist the LS with a projected 0-60 time of 4.5 seconds (RWD).

Perhaps more critical is how Lexus tuned the engine and transmission to deliver instant acceleration and a constant buildup of torque toward the engine’s redline.

A ladder frame structure in the cylinder block, redesigned engine mounts, electric wastegates and numerous other features help ensure the remarkable powertrain smoothness, a Lexus hallmark. The driver will be able to tailor powertrain response and feel by choosing from Normal to Sport to Sport+ modes, and just enough of the exhaust note can be heard to enhance the sporty feel.

The first-ever 10-speed automatic transmission for a premium passenger car, having already debuted in the Lexus LC 500, is also used in the new LS flagship sedan. It is a torque-converter automatic, yet with shift times that rival those of dual-clutch transmissions. The wide bandwidth afforded by ten closely spaced ratios is ideal for all forms of driving, helping to provide an optimal gear for all conditions.

Shifting via paddles is available, yet many will prefer the advanced electronic control system, which anticipates the driver’s input. The system chooses the ideal ratio by monitoring the acceleration, braking and lateral-g forces.

For starting acceleration, the close ratios of the low gears and the shortened shift time enable a rhythmical and exhilarating acceleration feel. The high torque of the twin-turbo engine matches ideally with the higher gear ratios for effortless, serene highway cruising, yet very quick downshifts yield direct acceleration with no lag in G response.

Torque converter lock-up activates in all ranges except when starting off to provide a direct feel, while also supporting fuel efficiency.
