The 63rd annual IAA heralded the introduction of a slew of environmentally-aware new vehicles from European automakers. The vast exhibition halls in Frankfurt played host to the avant-garde BMW Vision EfficientDynamics concept, four new electric car concepts from Renault, a 2.5m-long futuristic concept from Peugeot, Citroen's Revolte showcar and the L1 tandem vehicle concept form Volkswagen. But that's not all. Frankfurt debuts also included the Ferrari 458 Italia, two new performance-oriented Coupe and Roadster concepts (which we will see emerge in production form in the near future), and the Mercedes SLS AMG, proving that the performance car segment is still alive and well.
