Jaguar X-Type 2.2 D Sport

We've already tried the 153bhp 2.2-litre diesel X-Type in saloon form (issue 863), but how does the estate fare on UK soil? Jointly developed with Ford, the engine also powers the blue oval's quickest diesel Mondeo - the ST TDCi. The six-speed gearbox is the same, too.

On the move, the unit feels much stronger than the 130bhp 2.0-litre var-iant. A second has been shaved off the 0-60mph time - taking it to 8.5 seconds - but this car is best at speed.

Ordinarily, the 2.2 produces 360Nm of torque, yet under brief full throttle 'over-boost' conditions, 400Nm of thrust is offered. Acceleration is impressive in all gears, but particularly third and above. Jaguar quotes a 50-75mph time of only 6.7 seconds in fourth gear, which means overtaking is achieved quickly and safely. This is complemented by the precise gearbox, which offers a long sixth gear for relaxed cruising.

As a result fuel economy is excellent, with 47mpg on the combined cycle. Company drivers pay little more for the 2.2-litre over the 2.0 in tax, either - the benefit-in-kind band moves from 16 to 18 per cent.

Unfortunately, while road noise is well suppressed thanks to new laminated glass, refinement deteriorates at high revs. And despite having more performance, the 2.2 D isn't an especially sporty car, with soft brakes and the same comfort-oriented suspension as the 2.0 model. More enthusiastic drivers may be tempted by the Sport version tested here - which has uprated settings and 18-inch alloys - but its ride is harsh over bumps.

Regardless of trim, the X-Type Estate is a practical choice. Maximum stowage of 1,415 litres leads the class, while the split tailgate and quick-folding rear seats make loading easy. At ΂£24,165 - ΂£1,000 more than the 130bhp car - the 2.2-litre Sport adds a lot of performance for a modest increase in price.
