(January 19, 2018) DETROIT — Like molten metal being forged into a fine Japanese sword, the lines of the Lexus LF-1 Limitless concept have the potential to shape the future of a flagship luxury crossover for Lexus. Lexus established the luxury crossover segment two decades ago with the global debut of the RX 300 at Detroit.  It remains the top-selling luxury crossover despite nearly 50 competitors that have since entered the segment.

Now, the Lexus LF-1 Limitless concept introduces a new genre of luxury vehicle — the flagship crossover. Combining high performance with unrestrained luxury, the Lexus LF-1 Limitless is a showcase of technology, innovation and the latest evolution of design at Lexus.

Like its name, the possibilities for powertrains are limitless. The LF-1 concept could be powered by fuel cell, hybrid, plug-in hybrid, gasoline, or even all-electric. By around 2025, every Lexus model around the world will be available either as a dedicated electrified model, or have an electrified option.

The innovative spirit of the LF-1 was created at CALTY Design Research in California. The design language is rooted in the simple yet elegant design concept dubbed “molten katana”. This design visualization fuses the organic shapes of liquid metal with the sharp edges of a traditional Japanese sword. Imagining that shift from a smooth, flowing mass into a solid, chiseled shape formed the basis for the fluid, yet aggressive design of the LF-1 Limitless.



“This is our vision for a new kind of flagship vehicle that embraces crossover capability without giving up the performance and luxury delivered by today’s top sedans,” said Kevin Hunter, president, CALTY Design Research. “The LF-1 Limitless concept incorporates imaginative technology while creating a strong emotional connection by improving the human experience for the driver and passengers.” 

It starts with the right proportions. The Lexus LF-1’s exaggerated dash-to-axle ratio gives it an athletic profile that’s more sports car than station wagon.

Combined with a cabin that sits deep within the rear-wheel drive chassis and aggressive 22-inch wheels barely contained under bulging fenders, the LF-1 has a powerful stance that conveys its performance intentions at a glance. The low roofline and elevated ride height further emphasize that this is a crossover designed for performance with practicality.

Like all current Lexus models, the spindle grille on the LF-1 is a core element to the overall design. On the LF-1 it’s been taken even further, with details that suggest the start of the spindle form at the rear of the vehicle that then continues forward toward the nose. The grille itself features a three-dimensional design with colors developed in-house by CALTY. Ridges radiating away from the central emblem suggest magnetism guiding metal filings into shape. There is no chrome, as the LF-1 instead uses LED lighting around the grille that greets you on arrival.

“There’s no doubt that luxury crossovers are an increasingly popular choice for luxury customers,” said Lexus General Manager Jeff Bracken. “This LF-1 Limitless concept illustrates what could happen if Lexus were to add a flagship crossover to our line-up. It’s a gorgeous execution and we’re anxious to see our customers’ and dealers’ response.” 

In profile, the LF-1 has a clearly defined flow from front to rear starting with the front fender line that extends from the hood all the way to the bottom of the C pillar. That line contrasts with the more complex surfaces below it like the wide, crisply creased front fender that transitions to the smooth, deeply scalloped front door.

From there, the bodywork slowly builds back out again to envelop the rear wheel giving the LF-1 a broad, powerful stance.

A split spoiler grabs your eye at the rear of the Lexus LF-1, but there are interesting curves and details along every inch of the rear fascia. The beautifully sculpted openings at each corner might look like exhaust pipes but they’re actually vents for the air coming past the rear wheels.



The shoulders above those wheels provide sturdy mounts for the sculptural taillights that extend well past the metalwork. Above the lights is the huge expanse of glass that extends over the rear seats to offer an uninterrupted view thanks to the split spoiler on each side.  

Maximum comfort for every passenger was CALTY’s goal for the cabin. The Lexus LF-1 adheres to the Japanese tradition of omotenashi, or hospitality, welcoming all who enter with equal enthusiasm. The cockpit is designed to allow the driver to concentrate on the task at hand by removing distracting analog knobs and buttons in favor of motion-activated controls and a minimalist display directly ahead.

The front passenger space is far more open, with even fewer controls and a wide unobstructed dashboard. Those in back get the same seats as those in front with expansive legroom and individual display screens for adjusting the climate control or entertainment options.

The metallic interior trim is finished in the same champagne-tinted color as the exterior, but with a satin finish for a warmer feel.  Accents around the instrument panel and on the steering wheel further enhance the cockpit feel for the driver. Additional metallic accents throughout the interior contrast with the dark Cocoa Bean leather trim and seats covered in Chiffon White perforated leather.
