OFF-Road Performance
If you are a Jeeper, the first thing you will notice after engaging
4x4L is the absence of the old school Jeep's "torque wall" hitting you. The Thar doesn't feel like a diesel Jeep in 4x4L mode at all. It actually feels like a stock gypsy with lot more power. The crawling speed of the Thar is a lot faster than the MM540's and as a Jeeper, you don't feel comfortable over obstacles that require a tick over/precise movement & placement of the wheels. With a 4.3 differential ratio, the crawl ratio of the Thar is ~40 compared to the ~48 of the MM540. Even with a 4.88 differential, the crawl ratio of the Thar would come to ~45 (less than that of the MM540).
Comparison for approach, departure & break over angles:
We tried doing the EXAMM day 1 (

The Thar was lifting the wheels due to lack of articulation, and the open diff had the wheels spinning. In the end, Tejas did it again using the Thar's brute power. Some amount of pitching (and the front end dipping) was noticed here.
Video of the same obstacle:
Video from the 2010 EXAMM OTR for comparison. Do notice the stance of the vehicle that came there, vis a vis the production Thar:
The continuous back-and-forth resulted in the
useless bits getting bent (rear bumpers & steps mainly):
We moved on to the long descent of the EXAMM day 1, and did a timed 'NO ABC' crawl of both, the Thar and the Classic one by one. Either Jeep used 1st low for the descent. Here is a video showing the side by side comparison:
It is in the long climbs & ascents that the Thar shows it's true colors. With the sheer power & torque, it can go on and on. Read = Even after the old school Jeeps have given up gasping for breath. There is power available at the slightest tap of the accelerator pedal. We did the EXAMM day 1 long ascent (the descent in reverse) and the Thar was a lot smoother than the Classic accompanying us:
Testing in slush was next on my agenda. However, with the stock H/T tread tyres, we were wary of the Thar in slush. Our fears came true when it got stuck and had to be rescued by the Classic. With better tyres, the Thar should do a lot better in slush. However, one has to be careful of rocks hitting the IFS:
Oooppssss... one needs to be extra cautious. This does play at the back of your head:
Time to be pulled out by it's big brother, the Classic:
CAUTION 1: In a 4x4 Scorpio, with the front wheels stuck, the ease of the power steering can cause severe stresses on the front CV Joints. These are known to snap. The Thar shares a similar setup and one needs to be very careful.
CAUTION 2: The Thar with it's sheer power & torque can take off on short climbs with the front wheels in the air!! The landing back on surface can cause damage to IFS aggregates.
Our first 4x4 outing with the Thar had left us with mixed feelings and a realization that most of the time, it is the sheer power of the Thar that will overcome obstacles. Is that the best way to handle all terrains? What about slow & precise boulder crawling? What about the articulation? On the second day, we found a place to test out the IFS articulation. Baby boulders were up first.
For crawling over boulders, you need precise control over where your wheels are and tick-over crawl speeds. With a "NO ABC" approach, we were not able to crawl and place the Thar wheels where we wanted. The crawl speed of the Thar was simply too much. However, when we started controlling the crawl speed using the clutch, we were somehow able to pinpoint the vehicle to the exact spots & desired speed. Using just the brakes (and no clutch) did not yield the same results. Is crawling using the clutch a good option? I leave that to you to decide, but it's certainly not something that comes naturally to Jeepers. Gypsy owners? Probably.
We felt that the Thar should articulate more, and this made us test her out on another mud mound. This mound maxed out the IFS articulation capabilities of the Thar:
Notice how the leaf springs are flexing:

The maxxed-out rear shocks:
We also took the Thar to a dry river bed and here is the video.

The Thar can do more than 90% of the current Indian off-road trails 90% of the time, and that should be good enough for most Thar owners. Purist & hardcore off-roaders may find several shortcomings in the Thar, but this 4x4 is not aimed at the minuscule number of diehard offroaders either. For them, the Thar MDI platform could be an option, or there always is the existing route of building a customized 4x4.
Look at the brighter side: If you don't care about warranty & can afford the repair bills, you can drive straight to a Mahindra service station, after the OTR, and ask them to fix things. No longer waiting for that elusive nut/bolt combination (as you had to for old school Jeeps).
So, is the Thar a good platform to build your monster offroader on? Looking from a practical angle, maybe not! The cost & resources available to modify & strengthen the IFS, capability to add lift, fit in bigger tyres, lockable differentials & increase front articulation are still not clear.
On the other hand, and again, the Thar will easily meet or exceed the offroading needs of most of its buyers (that's 90% of the target segment). It is in the balance of superb on-road performance + acceptable offroad skill that the Thar is king.
