BMW TwinPowerTurbo technology again takes two of Ward’s 2013 10 Best Engines Awards. The 2.0-liter TwinPower Turbo 4-cylinder (N20) and 3.0-liter TwinPower Turbo inline-6 (N55) are both repeat winners.
“Nearly every BMW now sold in the US features TwinPower Turbo technology,” said Ludwig Willisch – President and CEO of BMW of North America, LLC. “In such a competitive market, to take two spots highlights the benefits of the BMW EfficientDynamics philosophy. It also shows that while we look for improvements in efficiency, we are still committed to fulfilling the promise of The Ultimate Driving Machine.”
Currently five models feature the 2.0-liter TwinPower Turbo 4-cylinder – Z4 sDrive28i, 528i Sedan, 328i Sedan, X3 xDrive28i and more recently, the X1 sDrive28i/xDrive28i. They will be joined next spring by the … CONTINUED
Have a look at some videos showing the assembly and internals/technology of the N20 engine.
The BMW N20 is a turbocharged inline 4 cylinder DOHC engine which replaced the N52 and BMW N53 inline 6 cylinder engines beginning in 2011. The N20 is an inline 4, but is considered a replacement for the straight-6 N52 and N53 because it powers equivalent models. It features a twin-scroll turbocharger, variable valve timing (VANOS), variable valve lift (valvetronic) and direct injection.
The N20 is currently used in:
E89 Z4 sDrive28i
E84 X1 xDrive28i
F25 X3 xDrive28i

Reviews of the 2012 Z4 sDrive28i featuring the new BMW turbo 4-cylinder N20 motor have generally been positive overall. However, Automobile’s recent assessment is the strongest endorsement we’ve seen yet for the new Z4, which represents the return of 4-cylinder BMW engines to the US.
Here are some of the great things the magazine had to say about the sDriv28i’s engine, exhaust, and performance.
Autoblog comes in with their first drive reaction to the 2012 Z4 sDrive28i, the first late model BMW to bring the 4-cylinder motor back to the US market. The N20 motor makes 240 hp / 260 lb-ft tq in the Z4, with a 7,000 rpm redline. Compared to the N52 inline 6 that it replaces, the Z4′s N20 has 15 less horsepowers but 40lb-ft more torque.
The N20 will also be making its debut in the 5-series line in the Fall with the 2012 528i, and in the 3-series with the all new F30 3-series sedan which will be unveiled this Fall.
Until now, the reviews of BMW’s Twinpower Turbo 2.0L inline 4-cylinder Motor (N20) were limited to drives of the X1 xDrive28i. But this Fall, BMW will launch the first US models to feature the N20 turbo 4-cyl motor — the 2012 Z4 sDrive28i and the 2012 528i. In the Z4 28i, the N20 motor makes 240 hp at 6500 rpm and 260 lb-ft tq at just 1,250 rpm, with a redline of 7,000 rpm. Compared to the N52 inline 6 that it replaces, the Z4′s N20 has 15 less horsepowers but 40lb-ft more torque.
So how does the Z4 28i drive? The first review is in, via Car and Driver. Some of C/D’s more salient words regarding the Z4 28i follow.
