Ford has had a 1.0-liter three-cylinder EcoBoost engine on sale in Europe and other markets for some time now and has received no shortage of praise for the tiny engine’s impressive fuel economy and surprising performance. General Motors and Opel are firing back at the lauded 1.0-liter EcoBoost with their own milk carton-sized three-banger in the upcoming Corsa E and AutoEvolution has decided to stack the two motors against each other.
Opel announced their 1.0-liter Ecotec three-cylinder when it pulled the veil from its Adam Rocks concept earlier this year, a more rugged version of the stylish Adam city car. The engine will find its way into more than one new Opel, including the new Corsa, and is available in either 88 or 113 horsepower versions. By comparison, Ford’s EcoBoost three puts out 98 horsepower or 123 horsepower.
Both Opel and Ford’s engines produce identical levels of torque (125 lb-ft) however the Ecotec produces the majority of its power from 3,700 RPM, while the EcoBoost waits until 6,000 rpm to really get chugging. In the Fiesta, the EcoBoost three-cylinder will allow the car to hit 180 km/h, the same max speed as the three-cylinder Corsa E.
That’s enough about performance, though. Both of these motors were built with fuel economy in mind, so who’s the real winner here? The Fiesta returns about 54 mpg on the US cycle, while the Corsa E will get about 51 mpg. AE points out you will never reach these figures in the real world and they’re right, so the differences in fuel economy here are negligible. As a side note, the Fiesta emits less C02, which puts it in a cheaper tax bracket in the United Kingdom, a major market for both of these vehicles.
