The Mahindra Thar Roxx, a five-door iteration of the renowned Thar SUV, has garnered significant attention for its blend of off-road prowess and urban practicality. A pivotal aspect of evaluating any vehicle’s performance is understanding its power delivery, particularly the difference between engine output and the power that reaches the wheels—a discrepancy known as drivetrain loss. To quantify this, enthusiasts and experts often turn to dynamometer (dyno) testing.
Understanding Drivetrain Loss
Drivetrain loss refers to the reduction in power as it travels from the engine to the wheels, influenced by factors such as the transmission, differential, and other mechanical components. In four-wheel-drive (4WD) vehicles like the Thar Roxx, these losses are typically higher due to the additional components involved in power distribution.
Mahindra Thar Roxx Engine Specifications
The Thar Roxx is available with two engine options:
- 2.0L mStallion Turbo-Petrol: Produces 160 bhp and 330 Nm of torque.
- 2.2L mHawk Diesel: Available in two configurations, delivering up to 171 bhp and 370 Nm of torque.
These engines are paired with either a 6-speed manual or a 6-speed automatic transmission, with 4WD capabilities enhancing its off-road performance.
Dyno Testing the Thar Roxx
A recent dyno test aimed to measure the Thar Roxx’s wheel horsepower (WHP) to determine drivetrain loss. The test revealed that the vehicle delivered approximately 130 WHP, indicating a drivetrain loss of around 20-25%, which is typical for 4WD vehicles.
Implications of Drivetrain Loss
Understanding drivetrain loss is crucial for enthusiasts and potential buyers, as it provides a realistic perspective on the vehicle’s performance. While engine specifications offer a theoretical maximum, the actual power available at the wheels determines real-world acceleration, towing capacity, and overall driving dynamics.
The Mahindra Thar Roxx exhibits drivetrain losses consistent with its 4WD configuration. Prospective owners should consider both engine output and drivetrain loss to gain a comprehensive understanding of the vehicle’s performance capabilities.
