When Ferruccio Lamborghini set out to compete with Ferrari, he contracted Giotto Bizzarrini to design the engine for his car and, according to some accounts, paid him a bonus for every horsepower over what Ferrari's V12 could produce.

Environmental aspects of the electric car produce tailpipe emissions, for comparison purposes the two most fuel efficient plug-in hybrids and the typical gasoline-powered car are included in the table. Total emissions include the emissions associated with the production and distribution of electricity used to charge the vehicle, and for plug-in hybrid electric vehicles, it also includes emissions associated with tailpipe emissions produced from the internal combustion engine. These figures were published by the EPA in October in its 2014 report ""Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends"." To account for the upstream emissions associated with the production and distribution of electricity, and since
