2018 Lexus LS500 – Video

It is possible that no single automobile has, upon introduction, upended its category as decisively as the first Lexus LS did when it launched the luxury brand 28 years ago. The 1990 LS 400 was the original luxury disruptor, winning critical acclaim and astonishing customers by setting new benchmarks for comfort, powertrain performance and smoothness, quietness, build quality, attention to detail, and dependability. The brand supported that groundbreaking vehicle by setting and maintaining new standards for customer service and satisfaction.

Now, Lexus is about to repeat history with the introduction of the all-new, fifth-generation LS flagship sedan for 2018, unveiled at the 2017 North American International Auto Show. Inside and out, the new LS reflects a strong, uniquely Japanese identity and approach to luxury. Yet, the LS was designed to be the brand’s latest global citizen, available in about 90 countries.

“Not only will the LS symbolize the Lexus brand, it will become the definitive new-generation luxury car embodying Japanese tradition and culture,” said Toshio Asahi, chief engineer for the new LS. “As such, this global pinnacle must go far beyond what the world expects from a luxury car.”

 

 

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.
