Peugeot Onyx Hybrid Concept - winner of Autoweek's Best Concept award.

Its doors and wings are all made of polished copper, and Peugeot left the copper pieces unprotected to allow the natural patina (tarnishing) effect to occur over time.

The remainder of the body panels are developed using a slightly less rare, but not too common, carbon fiber. Peugeot then draped the carbon pieces in a matte black to give the Onyx a sinister look rarely replicated in the automotive world.

Under the carbon-fiber hood on the Onyx lays a beast, in the form of a 3.7-liter FAP HDi V8 engine with hybrid technology. The V8 engine itself is a monster, pumping out an insane 600 brake-horsepower and transferring the power to the rear wheels via a 6-speed sequential gearbox. On the roof is a set of aluminum switches and the “Start/Stop” switch for ignition of this beast.

The Hybrid4 system in the Peugeot Onyx Hybrid uses regenerative braking to keep its batteries all charged up and tosses into the ring an extra 80 brake-horsepower when it is charged and ready to go. This brings the Onyx’s peak ponies to 680 brake-horsepower, bringing it dangerously close to the 2012 Aventador’s peak power.

The Onyx’s diesel engine puts out 1160 Nm (855 pound-feet) of torque and the electric motor puts out 280 Nm (206 pound feet) of torque for a combined 1,061 pound feet of peak torque. This would likely propel the Onyx to 60 mph in a TopSpeed-estimated 2.2 seconds – well faster than the Mighty Aventador.
