As they planned to put in a 3 Cyl Diesel, I expect them to use a 3 Cyl Petrol Turbo in the same power range. BMW is developing these to succeed the 4 Cylinder non-turbo engine (x16i / x18i / x20i) up to 170hp.
With this they can still be fuel economic and as in general a petrol has lower emissions then a diesel (if both have the same MPG) it still can be good.

VW proves that with a 1.2 TFSI petrol or 1.4 TFSI petrol great fuel economies can be achieved.
