In the high-speed gravel arena of the FMSCI Indian National Rally Championship (INRC), where all-wheel-drive machinery and turbo-boosted power plants often command the headlines, Bengaluru rally ace Chetan Shivram and veteran navigator Dilip Sharan have repeatedly rewritten domestic rallying physics. Piloting two-wheel-drive production platforms, Shivram captured the overall National Rally Championship title—a feat widely considered one of the greatest underdog triumphs in modern Indian motorsport history.
Competing against high-powered entries across the coffee plantations of Chikmagalur, the red clay switchbacks of Coimbatore, and the high-speed tarmac of the Popular Rally in Kerala, Shivram’s mastery of front-wheel-drive (FWD) vehicle dynamics has redefined how privateers approach stage rallying in South Asia.
According to championship archival records published by Autocar India INRC Coverage, Shivram’s competitive edge relies on precise slip-angle management, Scandinavian flick weight transfer, and aggressive momentum conservation.

Overcoming Terminal Understeer on Plantation Marbles
The greatest tactical enemy of any front-wheel-drive rally driver is understeer. Because the front tires must transmit steering inputs, acceleration torque, and the majority of braking force simultaneously, exceeding the tire's grip circle causes the car to push uncontrollably toward the outside bank.
Shivram overcomes this mechanical limitation through the mastery of the "pendulum turn" (Scandinavian flick):
- The Weight Decoupling: 50 meters before a tight gravel hairpin, Shivram steers briefly toward the outside edge of the stage, then sharply flicks the steering wheel toward the inside while simultaneously jabbing the foot brake.
- Dynamic Weight Transfer: This violent combination unloads vertical pressure from the rear axle, causing the rear tires to lose lateral grip.
- The Power Pull: With the rear of the car rotating smoothly into a 35-degree slide, Shivram pins the throttle wide open. The plate-type mechanical limited-slip differential locks both front wheels, pulling the front nose directly along the apex trajectory while the spinning rear wheels follow in the car's wake.
Co-Driver Timing: The Symphony with Dilip Sharan
Stage rallying is a team sport executed at 140 km/h between stone walls and rubber trees. In the navigator’s seat, Dilip Sharan delivers pacenotes with metronomic cadence.
A single hesitated syllable or miscalled corner radius can send a car plunging into an unbarricaded ravine.
Sharan’s notes are calibrated specifically for FWD physics:
- Calling corner tightness two corners in advance to ensure Shivram never loses turbo spool or exhaust momentum.
- Calling out "Cut" or "Don't Cut" based on exposed granite rocks that could shatter aluminum steering knuckles.
A Masterclass for Indian Grassroots Motorsport
In an era where international rallying is increasingly dominated by computerized, multi-million-rupee Rally2 machinery, Chetan Shivram’s triumphs serve as an inspiring masterclass for grassroots Indian drivers.
He proved that you do not require a factory-backed super-budget to stand on the top step of the national podium.
With deep mechanical empathy, intelligent chassis setup, and total trust between driver and co-driver, a well-driven front-wheel-drive car remains a lethal competitive weapon across the rugged, unpredictable gravel trails of the Indian National Rally Championship.
