Two new versions of the Land Rover Freelander, Europe's best selling 4x4, go on sale in the UK on Friday, writes David Duffy.

And, at the same time, there are upgrades across the Freelander range.

For the first time, a V6 version of the Freelander will be available. A five-speed automatic gearbox, featuring Steptronic 'manual' change, is standard. At the same time, Land Rover introduces a new turbo-diesel model using the Td4 2.0-litre common rail engine, made by BMW.

This engine offers substantial improvements in power and torque as well as much greater refinement compared with the outgoing turbo-diesel Freelander.

Both the V6 and Td4 versions will be available in three- and five-door body styles.

The 177 horsepower 2.5-litre V6 is available in two trim levels 'GS' and 'ES' while the Td4 adds an 'S' trim level. UK on the road prices start at 21,595 for the V6 three-door GS and 17,195 for the Td4 three-door S.

The Freelander V6 is a significant addition to the Freelander range that, since its launch in 1997, has become the best-selling 4x4 in the UK and Europe.

To improve braking, the new Freelander models have larger, vented, front brake discs and larger diameter rear drums.

A revised ABS system is now standard on all models. The system incorporates Hill Descent Control (HDC) to limit down hill speed when off-road and Electronic Traction Control (ETC) to limit wheel slip in conditions such as mud and snow.

All 2001 Freelander models also have a new bumper and grille with the Freelander V6 having a longer profile to suit the engine installation.

Clear direction indicator lamp lenses are a further distinguishing feature of the new models.

Available with both the V6 and Td4 engines, the top-of-the-range ES model features a high level of specification including leather seat facings, leather steering wheel and gear knob.

Heated front seats are standard as are illuminated vanity mirrors and powerfold door mirrors (optional on other models).

An electric sun roof is fitted and the in-car entertainment system incorporates a CD autochanger and remote, steering wheel-mounted controls.
