BMW’s new sports car developed alongside a new Toyota Supra is no longer thought to be called a Z5. Instead, it should stick with the Z4 name of the car it’s set to replace. Our latest spy shots reveal a design similar to what we saw on BMW’s 8-Series concept unveiled in May.

Buick’s new Regal GS is finally here. The handsome mid-size sedan adopts the fastback body of the Regal Sportback but adds V-6 power and a sophisticated all-wheel-drive system. The car encroaches on luxury sedan territory in terms of price, though it comes loaded with standard goodies.

Yes, we’ve driven the beast known as the Demon. It’s as brilliant as you were hoping for, and more. What’s the acceleration like? Easily the most intense and visceral experience you’ll have on four wheels—unless you’re a professional drag racer.
