India’s truck industry pushes for fairer efficiency rules to reflect real-world use

Truck makers say lab tests don’t capture reality. Now, India’s auto industry demands a smarter way to measure efficiency—and fairness for smaller cargo trucks.

India’s truck industry pushes for fairer efficiency rules to reflect real-world use

The Society of Indian Automobile Manufacturers (SIAM) has proposed changes to India's efficiency evaluation standards for trucks. The industry body seeks more accurate and fair assessment methods for different vehicle categories.

Currently, the Corporate Average Fuel Efficiency (CAFE) standards apply the same average fuel-efficiency targets to all vehicles in a manufacturer's fleet. However, SIAM argues that this approach is not suitable for efficient trucks, which have distinct operational characteristics and environmental impacts compared to heavier trucks.

Manufacturers of efficient trucks, such as light commercial vehicles (LCVs) and N1 category models, have minimal fuel consumption and CO2 output. They urge policymakers to separate efficiency rules for heavy-duty and smaller cargo trucks to ensure a more accurate and fair evaluation.

The industry proposes replacing constant-speed fuel tests with a model that captures real-world trucking conditions. This approach would provide a more accurate representation of a vehicle's efficiency in actual driving situations. Truck makers criticize the current draft rules for relying on fixed-speed laboratory evaluations, which they argue do not reflect real-world driving conditions.

SIAM recommends adopting the Bharat Vector Tool for efficiency evaluation, which is designed to capture the unique characteristics of different vehicle categories. The industry seeks an exemption for LCVs and N1 category models from the current efficiency rules due to their minimal fuel consumption and CO2 output. By implementing these changes, policymakers can ensure a more accurate and fair evaluation of truck efficiency in India.
