Are hybrids on their way out?

Dr Peter Harrop

Sales of hybrid cars in the USA collapsed from 3.2% of car sales in 2013 to under 2% in 2015 as Americans responded to the sharply reduced oil price. However the oil price will recover eventually so commentary that it heralds the death of hybrid vehicles is wide of the mark. Indeed hybrid car sales outside the US
