With its silhouette pushed to the extreme, the Onyx Concept Car fascinates at first sight. Its intensely aerodynamic lines take enthusiasts beyond the limits of high performance. Peugeot decided the Onyx's powerplant should be the diesel V8 from the 908 Le Mans car of 2011, which means that it has some pretty eye-watering stats. It's a 3.7-litre diesel producing 600bhp, but, unlike the 908, there's a hybrid element as well, adding an extra 80bhp.
