Is there a new, small, Ford petrol engine due out anytime? The 1.25 has been around for a long time and seems to lose power with every incarnation to meet emissions testing.
If Ford can create a cracking 1.2-1.4, free revving, highish power petrol engine in the spirit of the original lumps yamaha had a hand in designing they'd be onto a winner.
That and the 1.4 diesel found in the toyota yaris and auris - with a high output and low weight they'd be onto something, though obviously the current 1.6 is a good engine.
