Aston Martin’s new Zagato race car looks fantastic. But the real highlight here comes courtesy of the car’s completely unsilenced 6.0-litre V12 engine.

Here, Jamie Corstorphine finds out at Gaydon’s high-speed test facility.

At last, Mercedes has given us a worthy rival to the BMW 3-series coupe. Tested here in mid-spec diesel form, the car is refined and well-balanced when pushed. It’s also cheaper and cleaner than the BMW, so things are looking good. Here, Jamie Corstorphine puts it to the test in our quick fire review.

The Porsche 911 GT3 RS 4.0 is a hardcore, special edition that could be the best 997 911 of all.
