Thinking about a new hatchback? You might want to wait a second. The Mercedes-Benz A-Class Concept ($TBA) is the Tri-Star's newest compact concept, but doesn't skimp on the goodies — like a BlueEFFICIENCY 2.0L four-cylinder good for 210 hp, a dual-clutch transmission, a radar-based collision detection system, Adaptive Brake Assist, and museum-worthy looks. Here's to hoping they actually, you know, make the damn thing.
