The world got a look at Lexus’ future flagship this week at the Tokyo Motor Show, and it’s beautiful — massive grille, swept-back styling, 21-inch carbon-fibre wheels, and the barest squints of exterior lighting. Though it’s still a concept, the LF-FC is one of those exhibition cars that seems perfectly achievable, a logical evolution of the marque’s sporty sedan styling. And yes, that sounds a bit like damning with faint praise, but there’s some futuristic thinking going on here.

Attitudinally, Lexus has divided the car into two sections: a glassy driver’s cockpit designed for responsive driving, and a luxurious and limo-like passenger section with reclining seats. The car is (potentially) powered by high-output hydrogen fuel-cell system that powers electric motors at the front and rear wheels, for solid torque-distributed all-wheel drive.

And then, in the center console (where, here in the present, we merely place our lattes), there’s an “advanced human machine interface that can be operated by simple hand gestures.” That’s right, you only need wiggle your fingers inside a floating hologram, and the car will interpret your desire to change the radio station adjust the climate control, or make a phone call.

If they’re looking for a gesture that will hit the brakes and lay on the horn for 20 seconds, we’ve got one that’s proven both intuitive and effective.
