Codenamed X250, the next generation Jaguar S-Type will bring some fresh spirit and make a departure from the traditional Jaguar styling. In addition, such a departure seems to be more than necessary, as the sales of the feline badged manufacturer dropped like a Jaguar on its prey, lately.The most important design novelties are expected to be borrowed from the RD-6 concept car, presented in 2003. Such an element is the four traditional round front lights that will be joined together, two by two. The center grille will get more angular accents and a metallic finish. Angular accents will be found all over the body in a mixture with the traditional curvaceous lines.
Inside information spread in the media show that the new S-Type will not feature an integral aluminum chassis, like the XJ and XK do, but a steel chassis with several aluminum components. This may point that the new platform is an improvement of the current design, and not an entirely new project. This is a decision that might have been dictated by cost reduction necessities.No major changes are expected in the power-plant department. The base model is expected to feature a supercharged 3.2-liter straight six that will offer a good compromise between performance and mileage. The entry V8 will displace 5-liter and offer up to 350 bhp. The S-Type R will most likely be equipped with the 4.2-liter supercharged V8 currently available on the XK, but with an increased output towards 450 bhp. This would be necessary as the German competitors (BMW M5, Audi RS6) exceed 500 bhp.A diesel will also be offered as before. The 2.7-liter V6 features twin turbochargers and the latest, high-pressure, common-rail direct injection, making it among the most advanced high-performance diesel engines in the world. Innovations such as a Compacted Graphite Iron (CGI) cylinder block – which provides outstanding strength and durability as well as weighing less than a traditional cast iron unit – allied to state-of the-art electronic engine control systems have given Jaguar the engine that the marquee, and many thousands of potential customers, have been waiting for.The 2008 Jaguar S-type should hit the showrooms in the second part of 2007, as a 2008 model, and the S-Type R top of the range is expected to follow about a year later.
