CAFE III: Hastening slowly
The norms do not accelerate the needed transition

The recently notified third Corporate Average Fuel Economy (CAFE III) standard for passenger vehicles between April 2027 and March 2032 is a well-meaning attempt to steer the passenger-car industry towards lower emission norms. But questions arise on whether these norms have gone far enough to drive a meaningful transition. CAFE III mandates an improvement of roughly 16.7 per cent in fuel efficiency over five years. The fuel-consumption target is based on an equation linked to a reference weight and baseline fuel-consumption target across each manufacturer’s fleet. For CAFE III, the reference weight has increased from 1,082 kg to 1,229 kg. The higher reference weight seeks to address a demand for higher concessions for small cars, which became the subject of feverish lobbying by manufacturers. Crucially, the norms include a “super-credit” mechanism, which adds compliance values for cleaner vehicles. For instance, each battery electric vehicle (BEV) and range-extended EV will be counted as three vehicles for calculating fleet performance. Plug-in EVs and strong hybrid EVs using ethanol follow similar volume-derogation norms on a reducing scale. Manufacturers can also claim efficiency improvement for specified technologies such as start-stop systems and tyre-pressure monitoring, light-emission diode, or improved air conditioning systems.
