Renault's Koleos doesn't quite know what it is. This second-generation SUV from the French giant is also the second one built largely around the Nissan X-Trail, taking much of its mechanicals. The French flair, a key purchasing decision for many Renault owners, must come from the design, ride and handling, right?
In a market swamped with cars of this type, using a donor car is an economically sensible way to get things done. The risk is turning out a car with the badge of one manufacturer on the front but the character of another behind it.

While MY17 MU-X signalled a massive change for the better in Isuzu Ute Australia’s (IUA) SUV line-up, this year is more of a subdued affair.
Last year heralded the arrival of a new 3.0-litre engine, new six-speed automatic transmission, and upgraded Aussie-specific suspension, as well as styling tweaks; MY18 MU-Xs get extended service intervals and a new exterior colour.
It’s a clear case of IUA applying a ‘if it ain’t broke, don’t fix it’ approach to its popular ute-based SUV.

The Koleos is a sort of left-field choice, really, and that's probably not very fair. It's a proper mainstream car from a manufacturer that has been around longer than most, built on a proven platform.
It is, however, different enough for you to take notice. It looks good, has a bit of presence when viewed from either end and you can say you've got a Renault. It's only problem is it seems to be having and identity crisis.

The MU-X is a solid SUV wagon and it only continues to gain more appeal and, with it, a growing legion of fans. You certainly see a lot of them around – in the bush, in the suburbs and on city streets.
It’s not flash or posh but it’s a very practical daily driver or weekend tourer and performs very well in the real world. The top choice for me remains the LS-T.

Like Batman, the Koleos is a product of its origin story. That's not to say it's a weird orphan billionaire with a rubber fetish (although it has tyres, I guess) but that it was always going to turn out this way.
At first glance, it looks like a Renault, especially from the front, with the big C-shaped daytime running lights. Once in profile, though, it could be pretty much anything but it becomes more Renault at the rear again. So it stands out front and back but not so much from the side, which is unusual for a Renault. But then, it's a Nissan-based car built in South Korea, so it was always going to be a compromise.
Interior images show a mainstream design with a decent-sized screen but little in the way of French detailing. I'm a fan of Renault interiors generally even if they're not ergonomic masterpieces. This interior is certainly not as brave as its compatriot, the recently-arrived Peugeot 5008.
This launch marked no noteworthy styling changes in the MU-X, inside or out. It remains a blocky but good-looking unit, blending a bush-ready appearance with styling that doesn’t look out of place in an urban setting.
Build quality and fit and finish seem as sturdy as we’ve come to expect from IUA’s mainstream offerings.
For a Renault, the Koleos has a fairly conventional interior partly because it's based on another car. That means it has proper cupholders (the French are really bad at those), two up front and two in the back. Each door has a bottleholder, for a total of four.
Front seat passengers do very nicely indeed, with some models adding things like armrests for extra lounge chair comfort. The rear seat is spacious, with good leg and headroom, with room for three kids.
Boot space is generous - the Koleos is a big car. The luggage capacity starts at 458 litres, rising to 1690 litres with the rear seats down. The load area is a good size and shape, the packaging maximising the impressive interior dimensions. The glove box is large enough to hold the huge owners manual.
The MU-X’s cabin, unchanged, should remain an easy place in which to travel. It’s roomy enough for everyone.
The second row is a 60/40 split-fold with a fold-away centre armrest. The third row is a tight fit for adults but that’s nothing unusual in most seven-seaters.
There is 235 litres of boot space when the third row is up, expanding to 878 litres when the 50/50 split-fold third row is folded flat. When the second and third rows are down, there is 1830 litres of space.
The MU-X has 12 cupholders, 18 'storage solutions' (door compartments with bottle bulge, coat hooks, rear cargo organiser box, etc), USB ports (front and rear) and three 12V power outlets (centre dash, glove box and rear cargo area).
The MU-X has a braked towing capacity of 3000kg, 750kg unbraked.
Price and features
As always with our comparison articles, every price you see is straight from the manufacturer's price list and are RRP. Of course, how much you actually pay is between you and your dealer.
There are three models in the Koleos range - Life, Zen and Intens.
Pricing kicks off at $30,990 for the Life. For that you score 17-inch alloys, an eight-speaker stereo, dual-zone climate control, cruise control, remote central locking, reversing camera, rear parking sensors, auto headlights and wipers, cornering lamps, cloth trim, power windows, heated and powered rear vision mirrors and a space-saver spare.
The multimedia system features the usual AM/FM radio, USB and Bluetooth connectivity, plus Apple CarPlay and Android Auto. The Life doesn't have a navigation system, so your phone's GPS sat nav will have to do, which is fine if you've got data.
Next up is the Zen starting at $35,490 for the front-wheel drive (FWD) and $37,990 for the all-wheel drive (AWD). To the Life's spec list you can add 18-inch alloys, keyless entry and start (via Renault's smart key card), front parking sensors, heated and cooled front cupholders, electric driver's seat, sat nav, heated front seats, fake leather seats, sunroof, electric parking brake and roof rails.
The Intens is available in petrol ($44,990) and diesel ($47,490). On top the Zen spec you can expect a 12-speaker stereo, side parking sensors, heated and ventilated electric front seats, auto LED headlights, partial leather seats, power tailgate and auto parking.
Accessories include floor mats, at an eyebrow-raising $118.72, coloured key shells, boot liners, a towbar for over a grand, cargo barrier, bicycle carriers and the evergreen mudflap.
Not available are a bull bar or nudge bar or a body kit - unless you count the side steps.
There are eight colours - 'Mineral Beige', 'Metallic Black', 'Meissen Blue', 'Metallic Grey', 'Marron Red', 'Ultra Silver' and 'Universal White' all cost $880 extra. Only 'Solid White' is a freebie. McLaren Renault fans will be disappointed there's no 'Papaya Orange' option.
There are seven variants in the MY18 MU-X range: the 4x2 LS-M auto ($42,900), 4x2 LS-U auto ($45,200), 4x2 LS-T auto ($48,900), 4x4 LS-M auto ($50,200), 4x4 LS-U manual ($50,400), 4x4 LS-U auto ($52,500), and 4x4 LS-T auto ($56,200). All are seven-seater SUVs.
The base-spec LS-M’s standard features include 7.0-inch touchscreen with USB and Bluetooth streaming, reversing camera and rear park assist sensors, LED daytime running lights, gun metallic front grille, bi-LED projector headlights, colour-coded door handles and side mirrors, hill descent control, air-conditioning, power windows, and 16-inch alloy wheels.
The LS-U gets an 8.0-inch touchscreen, chrome front grille, door handles and side mirrors, as well as side steps, rear cabin cooling vents, and 18-inch alloy wheels.
The LS-T also gets leather-accented seats, passive entry and start system, six-way adjustable electric driver’s seat, roof rails, tailgate spoiler, chrome muffler tip and 10-inch DVD screen for rear passengers.
The MY18 MU-X is available in seven colours: 'Cosmic Black Mica', 'Obsidian Grey Mica', 'Havana Brown Mica', 'Silky White Pearl', 'Splash White', 'Titanium Silver' and the new 'Magnetic Red Mica' option.
Engine & trans
There are two engines available in the Koleos range. The Life, Intens, Zen and S Edition (a limited run version of approximately 360 units, based on the Intens) are all available with Renault-Nissan's 2.5-litre petrol automatic.
The Life is 4x2 only while the Zen and Intens are 4x4 only. The diesel is only available in the Intens.
The 2.5-litre produces 126kW/226Nm, propelling the non-AWD cars from 0-100km/h in 9.5 seconds, which is reasonable acceleration performance for a car of this size and weight (1552kg). The 56kg heavier AWD petrols will reach the ton in 9.8 seconds.
The turbo-diesel is a 2.0-litre motor and despite the smaller engine size than the petrol, puts out more power at 130kW and a substantially more torque at 380Nm. Zero to 100km/h is dispatched in 9.5 seconds.
Whether front or AWD, petrol or diesel, the Koleos comes not with an automatic transmission but Nissan's favoured continuously variable transmission (CVT). There is no manual gearbox or LPG option.
According to Renault's specifications, the braked towing capacity is rated at 2000kg for the petrol and, curiously, 1650kg for the diesel. That does seem strange given the extra horsepower and torque, but there you are.
As to whether the engines feature a timing belt or chain, both are lower maintenance chain-driven engines. As yet, there is not a battery powered or hybrid version.
As usual, the official fuel consumption figures are off by around 30 percent, which is about right. On the upside, the Koleos drinks only standard 91 RON for the petrol.
The two-wheel drive petrols will return 8.1L/100km while the AWD petrols a little more at 8.3L/100km. Diesel mileage is about 25 percent better at 6.1L/100km.
Given those figures, fuel economy is hardly going to decide whether you go for the 4x4 versions. A quick review of previous Koleos stories yields figures of 10.9L/100km for the heaviest petrol, the Intens. I recently drove the 4x2 Life and got just over 11.0L/100km.
Fuel tank capacity is the same petrol vs diesel at 60 litres.
We spent very little time in any new models and we’d have to drive a MY18 MU-X for a week or more to get a good handle on real-world fuel consumption but Isuzu claims the MU-X gets through 7.9L/100km (combined) in 4x4 LS-U and LS-T guises, 8.0L/100km (combined) in 4x2 LS-M, and 8.1L/100km (combined) in 4x2 LS-U and LS-T and 4x4 LS-M.
Every MY18 MU-X has a 65-litre fuel tank.
The Koleos, as I've already established, is built on the X Trail's guts and really feels very similar. That means if you're buying the Koleos hoping it feels like a Renault, you're out of luck. And that's not because it can't be done, it just didn't make much sense to do so. It's different to the X-Trail, but not massively so. It doesn't feel French.
Part of that is the CVT. While not the worst of its type fitted to a car in recent times, it makes the Koleos feel slow and a bit dim-witted. In normal driving it's perfectly fine and the noise suppression keeps the lawn mower effect to reasonable levels, but ask a little more of the transmission and it's not really ready for it.
And that's a great pity. While it's no ball of fire, it handles tidily, isn't actually as slow as it feels and is otherwise a pleasant car to be in.
Another complaint are the Life's tyres - they're not very good and could do with a bit more grip in damp conditions. Felt very odd to be losing traction accelerating gently out of corners.
The Koleos' off road ability isn't on trial here, but it's more than competent in the rough and slippy stuff when fitted with the AWD system. It certainly has the suspension travel, 21cm ground clearance and cosseting ride in all specs that you might expect from an off-roader.
Running 20 psi (pounds per square inch) in our Bridgestone Dueler or Toyo Open Country tyres, the Isuzus handled everything on the 4WD loop with ease, including runs up and down steep greasy-muddy hills peppered with rocks and tree-root hazards, tight turns in between trees, plowing through mud puddles and more.
No surprise at its efficacy on rough terrain because the D-Max and MU-X work off the proven '4X4 Terrain Command' system, operated via a dial near the auto shifter, and which can be switched on the move from 2High to 4High at speeds of up to 100km/h.
To engage 4L you need to be stationary.
The MU-X is 4825mm long, 1860mm wide (excluding wing mirrors), 1860mm high (the 4x2 LS-M is 1825mm high) and has a 3095mm wheelbase and 1570mm track. It has a 11.6m turning circle. Kerb weight is listed as from 1992kg (4x2 LS-M) to 2157kg (4x4 LS-T).
All MU-Xs except 4x2 and 4x4 LS-M models (220mm), have 230mm ground clearance. All MU-Xs except 4x2 and 4x4 LS-M models have 24 degrees approach angle (LS-M: 23.3), 25.1 degrees departure angle (LS-M: 24.6), and 19.5 degrees ramp-over angle (LS-M: 18.7).
The MU-X retains the benefits of the previous generation’s hill start assist (designed to hold gear during climbs) and hill descent control (which maintains engine-braking speed on downhills and is able to be regulated with acceleration or braking).
Underbody protection includes under-front steel plate skid/splash shield on every MU-X; and steel plate guards on the sump, transfer case and fuel tank leading edge on all 4x4 models.
The Koleos leaves South Korea with six airbags, ABS, stability (ESP) and traction controls, brake force distribution, forward AEB, reverse camera, forward collision warning and lane departure warning. There are two ISOFIX points and three top-tether restraints.
The Zen and Intens also feature blind spot warning and side parking sensors.
Since its 2016 introduction, ANCAP has not got around to crash testing the Renault for a safety rating. EuroNCAP has and awarded a five star rating in September 2017 with a safety spec identical to the Intens.
The MU-X has a maximum five-star ANCAP rating from April 2017.
Standard safety gear includes six airbags (dual front, side and full-length curtain), ABS with electronic brake-force distribution, ESC, traction control and EBA (emergency brake assist), 'Hill Start Assist' and 'Hill Descent Control', plus three top-tether ISOFIX child-seat points in the rear seat.
To cover off any problems or issues, Renault offers a five year/unlimited kilometre warranty and up to four years' roadside assist. Service costs are capped for the first three years and on both petrol and diesel, service intervals are an impressive 12 months/30,000km.
Pricing for the first three services is capped at $349 for the petrol and $369 for the diesel. That's a genuine bargain, with extra costs like filters laid out on the website.
As with its X Trail sister car, reliability appears to be excellent with few common faults. A run around the usual internet forums didn't uncover any common engine problems.
Resale value is slightly below that of its Japanese donor car, but depreciation doesn't seem as steep as some other Renaults.
Servicing is recommended at 12-month/15,000km intervals. Prices are: $350 (at 12 months/15,000km), $450 (at 24 months/30,000km), $500 (at 36 months/45,000km) $450 (at 48 months/60,000km) and $340 at 60 months/75,000km – for a total cost of $2090.
