Audi Crosslane Coupe concept

Rather than a design concept, the Crosslane Coupe is about the type of construction used for the vehicle and its drivetrain. Audi constructed this new space frame of aluminum, carbon fiber-reinforced polymer, and glass fiber-reinforced polymer. This type of space frame could save substantial weight in future Audi vehicles.

With two electric motors and a gasoline engine, the Crosslane Coupe gets 177 horsepower. The engine is only three cylinders, with displacement of 1.5-liter, which should lead to excellent fuel economy.

BMW Concept Active Tourer

BMW's Concept Active Tourer is either a preview of an upcoming 1-series GT that slots between the 1 and 3 series wagons or it's a stepping stone to an inexpensive front-wheel drive BMW model based on Mini underpinnings. Either way, this plug-in hybrid concept has an interesting all-wheel drive power-train that's worth exploring.

Peugeot Onyx

A bit further up the Peugeot performance ladder is the Onyx, a 700-horsepower, turbodiesel supercar that gets a staggering 118 miles per gallon. Yep, I'll believe that when I see it.
