Ford has announced its 1-litre EcoBoost petrol engine will power the Ford Focus, C-MAX, Grand C-MAX and the upcoming B-MAX, despite being small enough to sit on an A4 piece of paper.
Traditionally an engine of this size would be found in the Ford Ka city car, not the Grand C-MAX seven-seat MPV. But, this advanced motor is as powerful as a 1.8-litre engine from just a few years ago.
Its headline figures in the Focus will be 123bhp, with combined fuel economy of 56.5mpg and CO2 emissions of 114g/km, placing it in one of the lowest tax brackets.
Ford will also produce a version with 99bhp, reducing emissions even further, to 109g/km.
Big things are expected from the UK-designed 1-litre EcoBoost engine, with Ford planning to build as many as 1.3 million per year globally.
Graham Hoare, Ford's European engine guru said: "This 1-litre EcoBoost signals a new era of downsized, super-frugal engines".
It has the highest power output per litre of any Ford production engine, including the Ford Focus RS hot hatch and the Ford GT supercar.
