A REVISED version of Renault's diesel-only Koleos SUV has gone on sale with a choice of two new engines and priced from £28,195 in a simplified range and both paired with an automatic transmission.

Renault says performance, economy and emissions are optimised with the arrival of a duo of new Blue dCi engines, which are significantly more powerful and efficient than the units they replace.

The new 1.7-litre Blue dCi 150 engine is available in front-wheel drive only, while the larger 2.0-litre Blue dCi 190 is matched to Renault's intelligent All Mode 4x4-i system for surefooted handling and off-road capability.

Both units are paired with Renault's continuously variable transmission (CVT) and have been tuned to deliver maximum torque at only 1,750rpm.

As a result, says Renault, the latest Koleos shows notable improvements in real-world acceleration. All versions now also benefit from hands-free parking, making the driving experience even more relaxing.

Modest styling changes include LED headlamps, which are now standard across the range, and are part of a new front-end design that also includes a more prominent grille with chrome detailing, new bumper design, and a larger, more purposeful skid plate.

At the back, there's a bigger skid plate, additional chrome trim, new lower rear bumper and a larger high-level brake light that complements the 3D effect edge light tail lamps.

Inside, the revised Koleos gains new soft-touch materials and revised satin trim inserts. Rear seat passenger comfort is also improved, with a two-stage reclining seat back now standard on all models.

The introduction of a pedestrian detection function for the Active Emergency Braking System (AEBS) completes the revisions. Other advanced safety systems fitted as standard include Blind Spot Warning, Lane Departure Warning and over speed prevention with traffic sign recognition.

Following the launch of the Koleos EasyLife range in October last year the Koleos continues to be available in a simplified, more focused range, which consists of two trim lines - ICONIC and GT LINE. Both trim lines can be specified with either of the new Blue dCi engines.

Standard equipment across the range includes a seven-inch screen with satellite navigation and smartphone replication, front and rear parking sensors with reversing camera, hands free keycard, automatic dual zone climate control, full ‘Pure Vision' LED headlights, cruise control and speed limiter, automatic lights and wipers, heated/cooled cup holders and auto-dimming rear-view mirror.

The ICONIC features new 18-inch two-tone alloy wheels, while new 19-inch versions are standard on the GT LINE. The sporty GT LINE also adds a powered tailgate, leather upholstery with heated, electrically-adjustable front seats and an 8.7-inch portrait infotainment screen.
