Jaguar XF Diesel S: more power, less fuel

The Jaguar XF gets a brand new engine

The new Jaguar XF Diesel S

Jaguar has given its XF executive saloon a boost with a new 3.0-litre V6 turbodiesel engine.

The new 271bhp engine is faster, more refined, and more efficient than the existing Jaguar 2.7-litre turbodiesel. It will be badged the Diesel S.

The new 3.0-litre unit officially consumes fuel at the rate of just 42.0mpg combined – a 12% improvement over the 2.7. CO2 emissions of 179g/km represent a 10% improvement.

Despite this, the new XF engine is 33% more powerful than the 2.7. It is capable of whisking the XF from 0-60mph in just 5.9 seconds – 1.8 seconds quicker than before – and offers an electronically-limited top speed of 155mph. It also has a mammoth 443lb ft of torque, giving it superb pulling power.

This new combination of power and efficiency for the is achieved thanks to the engine’s ‘parallel sequential’ turbocharging.

The first time this has ever been used on a V-engine, it uses two turbochargers acting in sequence to give a smoother, more fuel-efficient response. The engine also features the latest generation diesel injection technology.

Other distinguishing features for the XF Diesel S include 19-inch wheels, a boot spoiler, and ‘S’ badging. It is priced from £36,900 – making it highly competitive compared to cars like the BMW 535d, currently priced at £39,535.

A 237bhp version of the 3.0-litre diesel is also joining the   line-up. Again, this offers greater performance but reduced fuel consumption compared to the old 2.7-litre diesel. This is priced from £33,900.

Both versions arrive in the UK in March 2009. To find out more about the Jaguar XF, watch our and for new and used prices, check out the .
