Detroit - General Motors will unveil a hydrogen fuel-cell-powered Cadillac crossover concept vehicle at the Consumer Electronics Show in Las Vegas this week.
GM envisions the five-passenger Provoq going 480km on a single fill-up of hydrogen, getting 450km from hydrogen power and 32km from batteries.
It would go from zero to 100km/h in 8.5 seconds and have a top speed of 160km/h.
The aerodynamic Provoq's hydrogen fuel cell would charge lithium-ion batteries to power one electric motor for the front wheels and another for the rear.
The vehicle could also be the basis of a replacement for the SRX, a larger crossover vehicle powered by V-8 and V-6 engines, Cadillac officials said.
The Provoq has a solar panel in its roof to power accessories such as the interior lights and audio system, the company said.
"All the people- and cargo-carrying capability customers expect in crossovers and SUVs is available in the Provoq, along with the premium attributes expected in a Cadillac," Ed Welburn, GM's vice president of global design, said in a statement.
No date has been set to bring the Provoq to showrooms, nor has pricing been discussed, the company said.
