This would cover all *14i, *16i, and *18i vehicles, which means 1 series, 3 series, and X1.

Thus, I would be very surpised if BMW's intentions are anything other than to fully replace both the current N18B16 (Mini 1.6L) and N13B16 (BMW 1.6L) four cylinder engines with this new 1.5L I3. To not do so would completely undermine the gains made by the increased economies of scale.

Furthermore, especially if the 225hp version in the I3 is accordingly efficient, I would not be surprised to see this engine additionally take over the *20i role from the current N20B20. After all, the current *20i models are only at about 184hp. Even if BMW intends to raise that to around 200hp in the coming years the I3 would still suffice. And for that matter, today's *25i N20B20 offerings (just the F20/F21 125i for now, but possibly more soon) could theoretically transition to this engine as well.

Jason or southlight - any idea what the code is for this engine? N10 perhaps?
The N37 3 cylinder will be used in the F56 MINI and the F20 114i, and the FWD BMW. Production is to start in Hams Hall UK not that far out. Peak power is to be around 220hp but that is reserved for only certain low volume products.

The reason they launch the 114i is for marketing purposes really, it is a four cylinder and will be replaced by a more powerful and efficient 3 cylinder- automatically kills detractors.

The N20 is under tuned right now, but there are changes to the six cylinder lineup as well coming with the launch of the replacement to the 3 series coupe (and F80 M3). Things are said to get interesting...

ZF is also working on that 9 speed for MINI/FWD BMW configurations, but there is a DCT being tested as well according to sources. Whatever makes the most cost sense and has better packaging will get the nod.
