Under the hood, the mu-X gets a 3-litre turbo diesel mill (same as in the mu-7) tuned to produce 174bhp at 3,600rpm and 380Nm of torque between 1,800rpm to 2,800rpm and is mated to a 5-speed auto gearbox. Currently, Isuzu is only offering the mu-X with this engine. There is no manual transmission available, but you could choose either from a 4X2 or a 4X4 variant. The latter gets a shift-on-the-fly system, where one can toggle between 2H and 4H at speeds up to 100kmph. If you are an adventure junkie, there is also a third driving mode – 4L, which enhances the SUVs ability to conquer the rough terrain.
The 3-litre diesel engine is not quiet for sure, especially in the first two gears as they are short and rev out quite quickly. But once the mu-X picks up pace, it becomes a lot quieter using the 380Nm of torque well. At engine speeds above 1800rpm up to about 3000rpm, the SUV is at its comfortable best, the torque converter automatic shifts seamlessly and good pace can be maintained. It’s just not one of those engines that like to be hustled.
Is it a roller coaster ride?
The mu-X is set up soft so at slow speeds, you won’t feel a thing inside the cabin. But that positive attribute turns out to be a drawback as speeds rise as the SUV doesn’t feel as stable as a Endeavour does. The nose dives when you brake with a little extra force and the body rolls a lot in corners. The steering too is unnaturally heavy for an electric power steering unit. It feels fine on the highway but is a proper workout while driving in the city.
Tackling the rough road
Owing to such a soft suspension setup, at first, I was a little apprehensive about whether or not the mu-X will be able to handle rough roads well, but I was sure in for a surprise. We turned off the highway outside Mumbai in search of a place where we could kick some dirt. A small hill on the outskirts of Kharghar with steep inclines, rocks, descents and a dirt track to drive on turned out to be the perfect testing bed for this 4WD SUV. The 220mm of ground clearance made sure the mu-X did not scrape its underbelly even once. Slotted in 4L the mu-X clambered over rocks with ease. With a 30-degree approach angle and a 25-degree departure angle the mu-X felt at home as I feathered the throttle while crawling over rocks along the way. As with all off-road vehicles, articulation plays an important role in off-roading. It can also handle up to 47 degrees of incline angle which is very impressive. This is useful info in the off-roading context since you will always scale a hill at an angle. Overall, the mu-X is a fairly capable off-roader but given how its focus was more on being a comfortable SUV, it has its limitations.
The Isuzu has its strengths and weaknesses. It is big and butch, which the Indian SUV buyers want, it is comfortable over all sorts of roads and trails at slow to medium speeds and comes with the option of a 2WD and a 4WD, depending on your needs. On the down side, its competitors offer more features, feel more refined and offer wider service networks. To give it a fighting chance at survival in this competitive segment, it is being sold at Rs 5-6 lakh cheaper – Rs 23.99 lakh for the 4×2 and Rs 25.99 lakh for the 4×4. Buy the mu-X for its good pricing and macho styling, but if you can stretch your budget, there are better all-round SUVs in the segment.
