Despite all the current hype making people believe that electric and hybrid vehicles are a staggering present day breakthrough in the quest for a carbon zero future, both are, in fact, old technology introduced over 100 years ago that has been refined. This book takes a look at how gas, hybrid, and electric propulsion has been redeveloped after disappearing during the twentieth century and is now regarded as ‘the future’. Although not intended to be a definitive history of public road transport in the UK, within its pages are several other technological and vehicle design developments that made their debut over a century ago and have made a return in recent years, all of which are illustrated and described to provide a fascinating insight of how things have continued to change.
