BMW has spent the past four years developing the new M4 Coupe and newly-announced M3 saloon from scratch – all with the intention of making its road-racer range more focused, more able and more relevant to modern motorists. They are faster, sharper and more dynamic, promises the firm, but also greener, smarter and more flexible than ever.

Audi preps S3 Cabriolet for Geneva

Audi revealed the S3 Cabriolet on Wednesday, before its Geneva motor show debut. The go-fast version of the small A3 Cab shares the same widespread MQB architecture as the rest of the 3 range, but it gets a hotter engine, a lower stance and, of course, a rag top. It’ll arrive in Germany this summer, and possibly here sometime after the S3 sedan in early 2015.
