Jeep Renegade Concept (2008)

The advanced propulsion system in the Jeep Renegade concept starts with a 40-mile lithium-ion battery pack. A range extender - in Renegade's case, a small-displacement (1.5-liter, 3-cylinder) BLUETEC diesel engine - allows for journeys beyond 40 miles. In fact, the Jeep Renegade concept boasts a 400-mile range.

Renegade's BLUETEC diesel engine generates an additional 115 horsepower when needed, while greatly reducing exhaust emissions when compared to standard gasoline engines. Renegade is capable of achieving an equivalent petroleum fuel economy of 110 miles per gallon, which is four-to-five times greater than an equivalent gasoline-only vehicle.

The all-new Jeep Renegade concept's lightweight aluminium architecture and regen-braking system help to improve overall efficiency, while dual electric 200 kilowatt (268 horsepower) motors propel a very capable 4x4 system - complete with low range and locking differentials -- worthy of carrying the Jeep name.

 Layout: Four wheel drive with low range and locking differentials,Motor: Dual electric,Power: 200 kW (268 hp) x 2,Regenerative braking,Battery: 16 kWh Li-ion battery pack,Range extender: 1.5-liter, 3-cylinder diesel,Fuel volume: 10 gallons.

Audi Cross Cabriolet Concept

Audi Cross Cabriolet is an attempted merge of a rag-top convertible and a full-size SUV.  At 182 inches this concept is a full two-and-a-half feet longer than the Audi A1 Metroproject Quattro concept, but it is also eight inches longer than a four door Jeep Wrangler. The concept is also 75.2 inches wide, similar to the Mercedes M-Class. The Audi Cross Cabriolet is actually based on the chassis and drivetrain structure of the A4 and the A5.  The car’s height of 64.2 inches is almost five inches taller than the A4 convertible. A 3.0 liter, 240 horsepower TDI engine with 369 ft-lb of torque gives this new breed of crossover its muscle, while the quattro permanent four-wheel-drive system gives it some all-terrain capabilities.  21-inch wheels are found on this concept, which also comes with electric ride height adjustment. The Audi Cross Cabriolet quattro gets an average of over 32 mpg on diesel. Audi has combined Google Earth with its own navigation system. The all-LED exterior lighting (headlights, taillights, turn signals, etc.) is a nice touch.  Underbody guard and metal running boards should help this vehicle travel across sand, gravel, or rock.
