It’s no secret that BMW’s been plotting to return a four-cylinder engine to its U.S. lineup post-haste, and we’ve finally seen the first result as BMW debuted the Z4 sDrive28i at the New York auto show today. Though the engine hood release was disabled on the display car, within that yellow snout should reside an all-new 2.0-liter turbocharged four-cylinder engine.
While you might guess that the new four-cylinder Z4 would slot underneath the current naturally-aspirated inline-six in the lineup as a bargain-priced, entry-level model, but we’re wagering that’s not the case.
