BMW X1 xDrive28i - 4-Cylinder TwinPower Turbo Engine
BMW models with the designation 28i will no longer be equipped with a 6-cylinder engine. Moving forward, they will be fitted with a next-generation 4-cylinder gasoline engine complete with BMW TwinPower Turbo technology. The first model available with the 4-cylinder BMW TwinPower Turbo engine is the BMW X1 xDrive28i, which has already made its debut in Canada. Here in the U.S., we don't have too long to wait. The new BMW X1 xDrive 28i is expected to arrive this fall.
The 2.0-liter 4-cylinder engine that powers BMW's anticipated X1 xDrive 28i is even more powerful than its 3.0-liter 6-cylinder engines, which thanks to TwinPower Turbo technology produces a laudable 245-horsepower (hp) and 258 lb.-ft. of toque. Previously, BMW's TwinPower Turbo technology has only been applied to their 6-cylinder models. As the technology makes its way to the 4-cylinder 28i, we expect it to eventually be integrated into other models as well.
BMW's TwinPower Turbo technology is comprised of a twin-scroll turbo-charging system, direct fuel injection, and solenoid injectors - which represent the latest advancement to BMW's VALVETRONIC variable valve control system. This provides the 4-cylinder engine of the X1 xDrive28i with a significant torque update over the previous 6-cylinder engine and substantially improved fuel economy. Reaching a top speed of 149 mph, the BMW X1 x Drive28i comes standard with a 6-speed manual transmission and all wheel drive or with an available 8-speed automatic transmission. The new 0-62 mph acceleration time is a mere 6.1 seconds (and 6.5 seconds for the automatic) - a healthy .7 second improvement compared to the last iteration.
