Peugeot RCZ: Best Sports Coupe 2011
At the Auto Express Best New Car Awards, the Peugeot RCZ Sports Coupe has been named Best Sports Coupe for the second consecutive year.
Auto Express said: "The flagship GT THP 200 is the stand-out choice in the RCZ range. It sprints from 0-60mph in 7.3 seconds and has agile handling to match. The short-throw gearbox, grippy chassis and responsive steering give it the edge over rivals. And it all comes wrapped in the most eye-catching bodywork around."
