Hybrids beat all-electric on CO2 emissions

An on-the-road test of low-carbon vehicles has shown all-electric cars are the most energy efficient but are yet to beat hybrids on carbon savings

Hybrid vehicles have pipped all-electric cars to be the biggest carbon savers, show the results of the RAC Future Car Challenge released in May.

The challenge, run last November, pitted 63 low-carbon vehicles against each other to see which used the least energy over a 57-mile drive from Brighton to London.

Fifty entrants allowed the organisers to analyse trip data and compare the carbon-saving performance of all-electric vehicles, highly efficient diesel cars and hybrids that have electric motors and internal combustion engines.
