Ferrari 458 Italia vs Porsche 911 GT3
Ferraris latest 562bhp V8 Berlinetta has changed the way we think about sports cars - its the first of a new, digital breed. The Porsche 997 GT3 RS is perhaps even more stunning on road than it is on track. Its ingredients are more basic, but its appeal is infectious.
They're not direct rivals, but theyre two of the most exciting high performance cars well drive all year. Chris Harris attempts to adjudicate.
