Jaguar has revealed its latest attack on its German rivals will be unveiled in production form at the Paris auto show in September. The F-Type, the automaker’s aluminium two-seater sports car, will be Jaguar’s fourth model alongside the XJ limousine, XF sports sedan and the XK four-seater convertible and coupe. It will be pitched against models such as the new Porsche Boxster, the Mercedes-Benz SLK, Audi TT Roadster and BMW Z4.Jaguar SA has confirmed the F-Type will be launched here in June or July, 2013. LITTLE CAR, BIG POWERThe F-Type will be launched as a convertible with a choice of three petrol engines: versions of Jaguar’s new supercharged 3-litre V6 and its powerhouse supercharged 5-litre V8. All derivatives will be equipped with an eight-speed transmission that will drive the rear wheels. Adrian Hallmark, global brand director for Jaguar Cars, said: "The unveiling of the F-Type in Paris (on September 27, 2012) will be a truly significant day in Jaguar's history as it will mark the company's return to the sports car market, a market it originally helped to create."As its sporting forebears did in their era, the F-Type will break new ground by delivering stunning sports car performance while vividly demonstrating Jaguar's cutting-edge engineering technologies and world-class design excellence. The next step in Jaguar's sporting bloodline is about to become reality."A crazy-wrapped prototype of the F-Type was first shown in public at the Goodwood Festival of Speed in June, 2012. TWO WORLDS, ONE JAGJaguar admitted much of the F-Type’s development was carried out in a “virtual world” that had the advantage, it said, of allowing engineers to concentrate on honing the sports car’s performance. Ian Hoban, Jaguar's vehicle line director said: "When you are working on a Jaguar sports car the expectations of the world are huge. We're really pleased how the attributes have translated from the virtual simulation work we've done into the physical world."Now, we're refining and adding those last few percentage points - that true element of honing which the Jaguar test team are delivering - which will turn a great sports car into an exceptional one."
