If you're looking for the fastest SUV in production right now, then look no further than Alfa Romeo's Stelvio Quadrifoglio. It's the current record-holder for the Nürburgring, at least as far as SUVs are concerned, and we just took one for a spin at the Circuit of the Americas.

Another vehicle we tested is Buick's new Regal GS. It may be front-wheel-drive-derived, but the Regal GS takes its place alongside the Kia Stinger GT as one of the more compelling cars we've driven in the past year.

Chevrolet showed a new Silverado at last month's Detroit auto show, and this week GMC one-upped its sibling brand with the new Sierra.
