Thermal efficiency refers to the power an engine generates from a unit of fuel.

The Nissan/Infiniti VC Turbo illustrates a challenge for policy makers eager to see the end of the internal combustion engine's dominance of transportation. 

While battery costs for electric vehicles are coming down, improvements in internal combustion engine efficiency could push the moment when electric vehicles achieve cost parity without government subsidies further into the future.

Advancing the internal combustion engine technology is 'one of the most overlooked trends in the industry,' James Chao, Asia-Pacific chief of consultancy IHS Markit Automotive, said. 

'These advances beg the question. Are EVs the best solution to the issue of vehicle greenhouse emissions?'
