Lexus has whipped the covers off its new LF-1 Limitless concept, essentially previewing a "potential" fresh flagship crossover for the Japanese brand.

The new show car, which was revealed at the North American International Auto Show in Detroit, was styled by the CALTY design studio in Southern California. It measures 5 014 mm long (a little shorter than the Lexus LX) with a wheelbase of 2 974 mm, a width of 1 986 mm and a height of 1 605 mm.

So, what’s under the bonnet? Well, Lexus says the LF-1 concept “could be” powered by fuel cell, hybrid, plug-in hybrid, petrol or electricity alone.

“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.”

Lexus says the LF-1 features a “chauffeur mode”, which allows for hands-free operation thanks to the vehicle’s by-wire steering, braking, acceleration, lights and signals. Other interesting features include the split rear spoiler and something the Toyota-backed brand calls "4D" navigation (which acts as a concierge 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).

Interestingly, all powertrain controls are sited on the steering wheel, including buttons on the lower section of the tiller to engage options such as park and reverse.
