The prototype shown here is said to have a V-6 engine with about 284 horsepower and an automatic gearbox. It's most likely Saab's current turbocharged 2.8-liter V-6. Sized beneath GM's current large crossovers, the 9-4X is imagined as a natural competitor for the BMW X3, Audi Q5, and Acura RDX.
The Saab shares its platform with the new Cadillac BRX, but this Saab prototype shows some distinctive touches from the Cadillac mules running around Michigan. The A-pillar has a more raked angle, and it's blacked out; the roofline, too, gives a good indication of this car's Saab design cues, as does the grille opening seen through the camouflage.
We'll have more details on the new 2010 Saab 9-4X as they're released.
