Nissan has thrown all its toys at the dCi upping the range to create a new top spec T-spec version. It's the most comprehensively equipped car Nissan has ever sold in the UK since the launch of the 2.0-litre petrol T-spec, that is.

The T of T-spec stands for technology: for example the 2.2-litre 138 PS diesel engine that shifts the Primera to 62mph in around 10 seconds and, with 314Nm of torque available at just 2,000rpm, gives much more effortless overtaking than the equivalent petrol.

The unit is Nissan's own and uses modern common rail technology, helped by a six-speed gearbox, to achieve 46.3mpg on the combined cycle and a CO2 mass emissions figure of 164g/km. That number translates into a 19 per cent BIK band (including 3 per cent diesel penalty) for the 2003/4 tax year. And the price it's applied to: £19,500 for the five-door hatchback and £20,600 for the estate.

Which brings us onto the spec of the T-spec: seven inch colour display monitor and N-FORM dashboard; DVD satellite navigation system which covers all of Europe on one disc; cruise control; 'Plug and Go' hands-free phone operation; electronic stability programme (ESP); rear view camera; rain sensing wipers; auto dim rear view mirror; Xenon headlamps with wash, front foglamps; electrically adjustable and heated front seats; 17" alloy wheels; climate control air conditioning; Thatcham category 1 approved alarm system; CD radio with upgraded speakers and subwoofer, steering wheel mounted audio controls; leather upholstery; electric tilt/slide glass sunroof and more...

Is there a better equipped diesel for the price? Nissan thinks not.
