A comprehensive guide to choosing between the Mahindra Thar Roxx Rear-Wheel Drive (RWD) and Four-Wheel Drive (4WD) variants, detailing real-world utility, mechanical differences, and value-for-money analysis for Indian car buyers.
The Mahindra Thar Roxx has taken the Indian SUV market by storm. By adding two extra doors, extending the wheelbase, and packing the cabin with premium features, Mahindra has transformed what was once a niche, lifestyle off-roader into a viable family vehicle. However, this transition has brought a major dilemma for prospective buyers: should you buy the more affordable Rear-Wheel Drive (RWD) variant, or shell out the premium for the Four-Wheel Drive (4WD) version?
Historically, buying a Thar meant opting for a 4×4. But with the Roxx, Mahindra expects a significant chunk of sales to come from the RWD configurations. Let’s break down the mechanics, use cases, and financial math to help you decide which version deserves a spot in your garage.
The Core Dilemma: Daily Driver vs Weekend Explorer
Before looking at spec sheets, you need to be honest about how you will use the vehicle. The Thar Roxx is a heavy body-on-frame SUV. Unlike monocoque crossovers like the Hyundai Creta or Kia Seltos, it uses a ladder-frame chassis which inherently behaves differently on tarmac.
If your daily driving is limited to city commutes, highway road trips, and navigating the occasional broken road or waterlogged street during monsoons, the RWD variant is more than capable. Rear-wheel-drive vehicles push the car from behind, offering better traction under acceleration and climbing steep, paved inclines compared to front-wheel-drive hatchbacks or sedans. With 219 mm of ground clearance and generous approach and departure angles, the Thar Roxx RWD can handle 90% of what Indian roads throw at it.
On the other hand, if you plan to venture into deep sand dunes, slushy forest trails, or black ice in the Himalayas, the 4WD system is indispensable. Mahindra’s 4WD system on the Roxx includes a low-range transfer case (4L), which multiplies torque to help crawl out of sticky situations. It also features electronic brake locking differentials and a terrain response system to manage traction across sand, mud, and snow. If you do not intend to deliberately seek out these terrains, carrying the heavy 4WD hardware is simply dead weight.
Powertrains Under the Hood: M Stallion and mHawk Analyzed
Mahindra offers the Thar Roxx with two engine options: a 2.0-litre mStallion turbo-petrol and a 2.2-litre mHawk diesel. However, the drivetrain configuration you choose determines which engine tune and transmission options are available to you.
The Petrol Conundrum
If you prefer a petrol engine, your choice is simple: you have to stick with RWD. Mahindra does not offer the Thar Roxx petrol with a 4WD option. The petrol engine is incredibly refined and punchy, making either 150 bhp (manual) or 174 bhp (automatic). It is an excellent choice for buyers in the Delhi-NCR region due to the 10-year age limit on diesel vehicles. However, keep in mind that this engine is thirsty, with real-world fuel economy figures often hovering in the single digits under heavy city traffic.
The Diesel Dynamics
For those looking at the 2.2-litre mHawk diesel, both RWD and 4WD options are on the table. The RWD diesel produces 150 bhp and 330 Nm of torque. When you step up to the 4WD version, the engine is tuned to deliver 171 bhp and 370 Nm of torque. This extra power is necessary to offset the added weight of the front differential, transfer case, and drive shafts. The diesel engine is much more fuel-efficient, making it the practical choice for long-distance tourers.
Features and Cabin Comfort: Is the Premium Worth It?
Mahindra has not skimped on features for the RWD variants. You can get the RWD configuration in high-spec trims like the AX7L, which comes equipped with a panoramic sunroof, a 10.25-inch twin-screen setup, ventilated front seats, a 9-speaker Harman Kardon system, and Level 2 ADAS.
The 4WD variants add off-road-specific tech. This includes ‘Crawl Smart’ (an off-road cruise control that maintains a steady low speed while you steer) and ‘Intelli-Turn’ (which brakes the inner rear wheel to reduce the turning radius on tight trail switchbacks). If you aren’t off-roading, these features will remain unused.
The Math: Price Comparison and Variant Selection
The price gap between an equivalent RWD and 4WD variant is roughly Rs 2 lakh to Rs 2.5 lakh. While this premium translates to a higher EMI, it also results in a heavier vehicle that consumes slightly more fuel due to mechanical drag and weight.
| Feature/Specification | Mahindra Thar Roxx RWD | Mahindra Thar Roxx 4WD |
| Engine Options | 2.0L Turbo Petrol / 2.2L Diesel | 2.2L Diesel Only |
| Max Power (Diesel) | 150 bhp | 171 bhp |
| Max Torque (Diesel) | 330 Nm | 370 Nm |
| Transmission | 6-speed Manual / 6-speed Torque Converter | 6-speed Manual / 6-speed Torque Converter |
| Off-Road Hardware | None (Rear Electronic Locking Differential on select trims) | Low-range Transfer Case, Intelli-Turn, Crawl Smart, Terrain Modes |
| Real-world Fuel Efficiency (Diesel) | 11 – 14 km/l | 10 – 12 km/l |
| Price Range (Ex-showroom) | Rs 12.99 Lakh – Rs 20.49 Lakh | Rs 18.79 Lakh – Rs 22.49 Lakh |
The Verdict
For 90% of buyers, the Thar Roxx RWD is the smarter, more practical purchase. It gives you the commanding road presence, high ground clearance, premium features, and rugged appeal of the Thar without the fuel efficiency penalty and higher purchase cost of the 4×4 hardware. Only choose the 4WD if you are a genuine off-road enthusiast, plan to participate in recreational off-roading events, or regularly travel to remote areas with unpredictable terrain where getting stuck is not an option.
