[Car Enthusiast comment]
The Renault Koleos concept car is the third major concept from Renault in as many years, following on from the radical Vel Satis and the derivative Avantime. The Vel Satis is to go into production in the near future, albeit in toned-down form, as a replacement for the staid, and now dated Renault Safrane. The Avantime is also to go into production as a sporty alternative to the many multi-purpose vehicles on offer. It is thought that both concepts will be changed to incorporate four doors instead of the original two.
The Koleos concept uses Patrick Le Quement's styling features from the other concepts - the distinctive sharp face remains, as does the unusual Ford Focus-like treatment of the 'C'-pillar. It remains to be seen just how serious Renault are about producing a new off road vehicle though, as the Renault Scenic RX4 has just gone on sale. The Koleos would probably sell well in the States as a daring alternative to the smoothened brick SUVs on offer there! Do not be surprised if Renault incorporate some of the design features in the next-generation Scenic.

RENAULT KOLEOS CONCEPT CAR - A NEW TOP-OF-THE-RANGE LEISURE VEHICLE CONCEPT
Renault designers have a flair for innovation and after gems such as Scenic, Spider roadster, Espace,
Twingo and Avantime, they have now dreamt up a new concept vehicle that is neither a traditional saloon
nor an off-road vehicle, but an intelligent blend of both. To be unveiled at the forthcoming Geneva motor
show, Koleos (code-named Z10) is a landmark design that combines the on-the-road qualities and comfort
of a top-range saloon with the off-road capability of a 4X4. Styled to evoke power and strength, the new
concept car also offers prompt response and driving pleasure, with a hybrid power unit that combines a
two-litre 16-valve turbocharged petrol engine with an electric motor.
Off the road, the Koleos holds its own alongside a traditional 4X4, thanks to variable-height suspension
that affords similar capabilities. Koleos also places a major emphasis on technology: the vehicle's
essential functions are controlled via a screen with voice activation, and the headlamps feature an
innovative fluid optics concept.
With this concept car, Renault projects its values of vision and daring into the off-road segment. Following
on from the Scenic RX4, Koleos marks Renault’s commitment to address the SUV segment by reinventing
the leisure vehicle with a daring slant.
An off-road car with upmarket appeal: the best of both worlds
By successfully blending seemingly contradictory motoring values, Koleos plays the multi-purpose card,
with an innovative design that gives it a unique and highly distinctive personality. As a generously-sized
monospace, 4.50 metres long, Koleos initially comes across as a top-range saloon, with a fluid, streamlined
profile conveying dynamism and power. The side panels and arch-shaped headlamps are styled to create
the impression of a pouncing feline. This is an elegant and distinguished car, with all the performance and features of a top-range saloon.
The rear doors spotlight two original concepts. The tailgate uses the twin stage parallel opening
technology found on the Avantime side doors, and it slides to the left of the car as it opens to facilitate
access to the boot compartment.
The fully-modular boot is separated from the passenger compartment by a retractable window; a
mechanism lowers the rear window into the tailgate while the roof section above the boot slides
horizontally under the roof panel converting the Koleos into a pick-up.
The monospace format makes for optimized interior space. The passenger compartment exudes a sense of
well-being, comfort and brightness, with a windscreen that extends in two glazed lateral strips along each
side of the roof, for more interior light.
The four seats are of a truly new and innovative design - carbon sheets covered in hand-stitched leather
from the prestigious firm Connolly, whose inspiration here draws on saddle design - combine aesthetics
and ergonomics. Seat and back are supported by four damping cylinders, and the carbon laminates adapt
to body pressure to ensure optimum comfort.
Though the Koleos stakes very definite upmarket claims, this is no way detracts from its off-road
capability, which is clearly denoted through rugged styling features, compact format, and high ground
clearance. But the protective mouldings that extend along the wings to encompass the large-diameter
(21") wheels are discreet, highlighting rather than attenuating the elegant refinement of the exterior.
Variable-height suspension
The off-road temperament of Renault’s new concept-car is confirmed by variable-height suspension
featuring pneumatic and hydraulic springs that are capable of adjusting the vehicle height in a matter of
seconds. The transition between 4X4 mode (vehicle height 1.70 m) and saloon mode (height 1.60 m) is fully
automatic and depends upon both vehicle speed and the type of road surface. For sports-style driving on
the open road, a low position with stiffer suspension enhances the car’s dynamic response, while in high
4X4 position driver and passenger comfort is improved by a softer suspension.
High-tech features
High technology pervades the Koleos, but does so unobtrusively. That being said, technology does rise to
visible prominence in features like the speech-responsive screen that controls essential interior functions
like climate control, audio and driver guidance. Options are displayed for selection on a screen menu, and
can be triggered using a finger roller control.
The arch-shaped headlamps use a very recent technology derived from research conducted by French firm
Megalux into fluid optics. The light flow enters a dioptric fluid optic, which shapes the light and guides it
either to the lower half-arch for the dipped position or to the upper half-arch for the main-beam position.
Hybrid power unit for better environmental protection and driveability
Driving pleasure is a major requirement for any top-range vehicle, but with the Koleos Renault has sought
to meet this requirement without sacrificing environmental protection. The hybrid power unit on the Koleos
adapts intelligently to different driving phases, with electric, internal-combustion and hybrid modes
managed automatically by an electronic controller. In town, the Koleos is a clean car running in all-electric
mode, with lithium-ion batteries powering a 30 kW Renault Élégie electric motor that drives the rear
wheels.
On the open road, the two-litre 16V 170 bhp turbocharged F4R engine takes over, driving the front wheels,
with the electric motor providing an extra power boost if needed. In 4X4 mode the internal combustion
engine and the electric motor work together for maximum power and off-road capability.
Koleos is a genuine concept vehicle designed to gauge public reaction around the world to the idea of a
daring and luxurious 4x4. Only after this period of research will a decision be made as to whether or not
the world is ready for a vehicle such as the Renault Koleos.
