This week’s Autocar magazine stars one of the closest showdowns of the year, the new Range Rover Sport versus the Porsche Cayenne Turbo. Which is the ultimate sporting luxury SUV? We reveal the answer.

In an issue jam-packed with tests of exciting new cars, we also evaluate the radical, high-tech BMW i3, drive the 313mpg VW XL1 through London, sample the Skoda Octavia vRS to discover if it is a performance bargain and evaluate both the new diesel-powered Honda CR-V and the Fiat 500L Trekking.

The new and slightly controversial BMW 3-series GT is the subject of our eight-page road test. The sector-busting hatch gets its most thorough test ever, with its breadth of abilities earning both immense praise and some frustration.

Stories from our long-term test fleet include our new Renault Clio, plus updates on the Mitsubishi Outlander, Mercedes-Benz CLS and McLaren MP4-12C.

Visitors to the Goodwood Festival of Speed will enjoy our eight-page round up of the event, starring all the new launches —such as the McLaren 12C Sprint edition and Jaguar F-type Project 7 car, plus all the atmosphere and first-hand fun from our various drives and rides in cars as varied as the aforementioned McLaren and Jaguar XJR to the Vuhl 05, a Renault Twin'Run and Citroën DS3 WRC.

The news section is led off by the scoop story on the next Mitsubishi Evo, which is set to make use of hybrid race car technology to redefine its abilities. We also have new spy shots of the upcoming baby Jaguar saloon, which reveal the best clues yet about its styling.

The new Volkswagen Taigun baby SUV, high-performance Mercedes S63 AMG and practical Skoda Rapid Spaceback also star. We also have full details of the new budget Datsun Go, which relaunches the brand.

Budget car fans are in for a real treat, as James Ruppert casts an admiring eye at the Toyota Avensis, available in buyable condition from £400, and we size up the Citroën C4 as a used buy from £1250. We also ask whether you're better off spending £7000 on a new Renault Twizy or used Toyota iQ.
