With the North American International Auto Show still days away, information is leaking through sieve-like embargoes. Cadillac Provoq is a fuel-cell powered concept Crossover SUV that telegraphs cues for Cadillac’s future Crossovers like the next SRX. Of course, the first question is why Cadillac used a name for this concept rather than an alphanumeric like “TRX” or “URX” or “VRX”.
VehicleVoice will have more from the show floor next week when we can shoot the Provoq in the flesh.
Cues from Future Generation Cadillac Crossover SUVs
Provoq has contemporary body surfacing with a bold contour swage on the bodyside initiating from the inevitable gill in the front fender. The grille texture is very similar to the new CTS and closely follows Cadillac’s present design language. So from a design standpoint, Provoq is more evolutionary than revolutionary. Nice looking in the way the new CTS is nice looking.
The Provoq rides on a 110-inch wheelbase and has an overall length of 190-inches. So, it’s about a half-size smaller than the SRX (116-inch wheelbase and 195-inch overall length). Based on GM’s new compact crossover architecture, the Provoq has more to do with the Saturn Vue than the SRX.
Aerodynamics a Key to Improved Efficiency
The Provoq is optimized for low aerodynamic drag, with the front fascia featuring a computer-controlled grille that opens as cooling is needed. There is a wind-tunnel designed belly pan to smooth airflow beneath the Provoq. The functional rear spoiler helps reduce drag by smoothing airflow over the roof. In addition, the roof contains a solar panel for charging vehicle accessories.
Powertrain – Hydrogen Fuel-Cell
The powertrain is the fifth generation version of General Motor’s hydrogen fuel-cell stack. (The fourth generation is presently powering a fleet of 100 hydrogen Chevrolet Equinox SUVs that GM has put into a testing rotation with people in California, New York, and Washington.)
This fifth-gen version is one-third smaller than what’s on the road now, and its hydrogen fuel cell can provide a continuous output of 88 kilowatts. Three electric motors are expected to deliver 0-60 mph times of about 8.5 seconds with a governed top speed of 100 mph. The hydrogen is stored in two 10,000-psi tanks that hold 6 kilograms each, and the quick-fill feature works similarly to the Equinox test fleet. Range is expected to be 300 miles. The Provoq is also a plug-in hybrid incorporating a plug-in feature to pre-charge the lithium-ion batteries from your home electrical system. The ports for the plug-in hybrid are conveniently located on both sides of the vehicle. Both the brakes and transmission incorporate drive-by-wire technology.
While Provoq is a technology concept, think of it more as a styling and package concept for future Cadillac Crossover SUVs. When we see this styling on the road, it will be petroleum powered – either gas or diesel or maybe a gas-electric hybrid… but not a production hydrogen fuel-cell.
