What is it?
After the diesel's rise to pre-eminence in upsize family cars, the petrol engine is fighting back. Some of the tools in its armoury are direct injection, a turbocharger and clever interlinking of exhaust ports and turbo scrolls to improve exhaust scavenging.
Combined with inlet and exhaust valve timing variable over a very wide range, remarkable feats of power, torque and frugality become possible. Ford's new Ecoboost engines feature all of the above.
And the newest Ecoboost is this 237bhp version of the aluminium-block 2.0, found in the Titanium X Sport version of the newly facelifted Mondeo and replacing the thirsty five-cylinder.
It comes exclusively with a six-speed double-wet-clutch gearbox, and the Sport part denotes adaptive dampers with the usual Comfort, Normal and Sport settings. You'd expect paddle-shifters to go with this transmission, but they are strangely absent. Manual shifting therefore involves the central lever, with the Ford (and BMW) logic of pulling back for an upshift.
