It featured a biofuel hybrid engine and previews the next generation Saab 9-3 convertible.

It seems Daimler are ready to keep it going though.

8. BMW Concept X1

There was however one concept that stood out, the RC HYmotion4 Concept boasted a style that screamed out to the automotive enthusaist crowd and with a 0-100km/h time of just 4.4 seconds, it had a performance to match.
