BMW's new 2.0L 4 cylinder turbo engine (the "N20") may be down on cylinders and displacement compared to the inline 6 cylinder (N52) that it replaces across BMW's model range, but even in factory form, it matches the outgoing N52's horsepowers and features an extra 30 lb-ft of torque (in the X1 xDrive28i, X3 xDrive28i, 528i, Z4 sDrive28i, and upcoming F30 328i), while having better fuel efficiency.
And what the N20 loses in smoothness and top-end pull compared to the outgoing N52, it now looks like it will easily make up for in tuneability.
Kelleners Sport has released the specs of its N20 tune and the figures are impressive! These are power gains that the naturally aspirated N52 could never achieve.
The Kelleners N20 tune achieves
294 hp and
310 lb-ft torque (420 Nm), a
+49 hp and
+52 lb-ft gain over factory quoted figures. See the full specs below:
On the X1 sDrive20i/xDrive20i, X3 xDrive20i, 520i, F20 120i and Z4 sDrive20i models (which get a lower powered N20 configuration from the factory):
On the X1 xDrive28i, X3 xDrive28i, 528i, Z4 sDrive28i, and upcoming F30 328i model (which get the higher powered N20 configuration from the factory):
These power figures were achieved with their tune only and no other modifications. No doubt we'll see more aftermarket tuners releasing their N20 tunes, especially as the F30 328i hits the market.
