Little more info i got from net on the new petrol engine.
Soruce Ford Rolls Out Fuel Saving 1 Litre EcoBoost Engine - Singapore Motoring News - Oneshift.com
The 1.0-litre engine offers a number of innovative efficiency solutions:
- An offset crankshaft that reduces friction
- An advanced, Ford-designed split cooling system that allows the cylinder block to warm up before the cylinder head. Faster cylinder block warm-ups save fuel, especially in cold weather
- An exhaust manifold cast into the cylinder head. The one-piece assembly lowers the temperature of the exhaust gases. This enables the engine to run in a wider rpm band with the optimum fuel-to-air ratio. The new design also saves weight and allows the engine to operate more smoothly
- EcoBoost technologies, such as turbocharging, direct-injection and twin independent variable camshaft timing (Ti-VCT)
