As we predicted in the past, the first BMW in the United States to feature the new N20 four-cylinder TwinPower engine is the BMW Z4 sDrive28i. We also anticipate that the BMW 528i will receive the same engine this fall.

“The new BMW Z4 sDrive28i Roadster will be the first model in the U.S. to feature the company’s new powerful, efficient and clean TwinPower Turbo 4-cylinder engine. It also marks the return of BMW 4 cylinder power to the United States for the first time in over a decade.

This newest engine, another part of the company’s on-going development of BMW EfficientDynamics, is the latest to combine twin-scroll turbocharging technology with high-precision direct injection and BMW’s Valvetronic throttle-less control system. Taken together, these technologies improve performance while at the same time reducing emissions and lowering consumption.

With 240 horsepower and 260 lb-ft of torque, this new engine offers similar  power to the normally aspirated 3.0-liter inline six currently offered in the Z4 Roadster and more torque.. Maximum output of 240 horsepower is achieved at 5,000 rpm, 1,500 rpm lower than in the normally-aspirated 3.0-liter inline six. The peak torque of 260 lb-ft comes on stream at just 1,250 rpm. Not only is that nearly 20 percent more torque than the aforementioned inline six, it also peaks 1,500 rpm earlier.  The new BMW Z4 sDrive28i will arrive in US showrooms this fall.”

    I’d class the z4 2.8i as an FMR layout now. The engine will be way behind the front axle. This engine in this model will be a gem

    The N20 in this platform will be a winner. Can’t wait to drive one. Just wanted add some info. The N20 red line is 7000 rpm. The twin-scroll turbocharger housing is sourced from Mitsubishi (Borg Warner in the N55 I-6 cyl).

    A discussion of the new 4-cylinder turbo is nice but no performance assumptions can be made unless we know where BMW is going with the weight of the 3-, 5- and Z4 vehicles this is scheduled to power. If weight continues to go up performance will suffer regardless of how well the N20 stacks up against the predecessor powerplant. If curb weight of the next model 328i coupe tops 3,500lbs., for example, you’ll get better gas mileage with the N20 but you’ll be hurtin’ when it comes to acceleration (not to mention the fact that there will still be a little bit of turbo lag when compared to naturally aspirated motors).
