Limitless concept

The sharply chiselled lines of the luxury Lexus NX go even further on the LF-1 Limitless concept car, presented at the Detroit Auto Show – as does the tech installed in what the company calls a ‘new genre’ of luxury vehicle.

Combining high performance with unrestrained luxury, the Lexus LF-1 Limitless concept is a showcase of technology, innovation and the latest evolution of design at Lexus.

The concept envisages fully autonomous driving and could be powered by fuel cells, hybrid, plug-in hybrid, petrol 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.

Lexus International president; Yoshihiro Sawa says Lexus models such as the RX had helped drive the global popularity of the luxury SUV category.

“This new crossover concept captures a future that involves a high level of dynamic capability and utility matched by a more exciting, emotional design that we hope challenges expectations in the category,” he says.

The innovative spirit styling of the LF-1 was created at CALTY Design Research in California.

The design language is rooted in the design concept of ‘molten katana’ – fusing the organic shapes of liquid (molten) metal with the sharp edges of a traditional Japanese sword (katana).

CALTY Design Research president Kevin Hunter said imagining that shift – from a smooth, flowing mass into a solid, chiselled shape – formed the basis for the fluid, yet aggressive design of the LF-1.

“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,” Hunter says. “The Lexus LF-1 Limitless concept incorporates imaginative technology while creating a strong emotional connection by improving the human experience for the driver and passengers.”

The LF-1 has an exaggerated dash-to-axle ratio (long bonnet, short front overhang)  and combined with a cabin that sits deep within the rear-wheel-drive chassis and aggressive 22-inch wheels under bulging fenders, has a powerful stance that conveys its performance intentions at a glance.

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 has been taken even further: details suggest the start of the spindle forms at the rear of the vehicle, then continues forward toward the nose.

The grille itself features a three-dimensional design with colours 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.

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

The cockpit is designed to allow the driver to concentrate on the task at hand: distracting analogue knobs and buttons have been removed in favour 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.

Technology enhances the luxurious feel of the LF-1 by expanding the options offered to the driver. It starts with the LF-1’s Chauffeur mode, which allows for hands-free operation thanks to the vehicle’s by-wire steering, braking, acceleration, lights and signals.

For engaged driving, all powertrain controls are on the steering wheel to keep the driver focused on the road. Paddles mounted to the steering wheel control the transmission in manual mode for sporty driving while buttons on the lower section of the steering wheel engage standard drive mode options like park and reverse.

There is also a four-dimensional navigation system, which builds on traditional systems by adding the element of time to the equation.

It acts as a concierge for the occupants by anticipating the needs of the driver and passengers based on the progress, traffic and road conditions along the programmed trip, suggesting fuel stops, rest breaks and restaurants, even offering to make hotel reservations.

Navigation and route information are displayed on the in-dash monitor, the rear seat entertainment screens, or wirelessly connected to passengers’ tablets and smart phones.

Touch-responsive haptic controls easily reached from the steering wheel link provide a seamless interface with the 4D navigation system and integrated comfort and entertainment systems.

A touch-tracer pad embedded in the leather-covered centre console supports character recognition for data entry. An additional haptic controller in the rear-seat centre console allows passengers to make their own comfort and entertainment choices.
