BMW Z4 GETS NEW 4-POT OPTION
Apr 20, 2011
240hp 4-cylinder entry model on its way for roadster line-up
The BMW Z4 will be available later this year with the all aluminium 4-cylinder petrol engine already available in the BMW X1 xDrive28i.
Doubtless the advanced cadre of BMW nomenclature scholars here on PH will already have worked out what it's going to be called, but for the rest of you how does the BMW Z4sDrive28i sound?
BMW says the new engine with TwinPower Turbo tech provides increased torque, improved performance and much reduced fuel consumption and emission levels when compared to the existing 6-cylinder entry model - the BMW Z4 sDrive30 - which shouldn't come as much of a surprise. However BMW says figures won't be released until later in the year, suggesting there's a bit more fettling and/or testing to be done.
As in the X1, the engine features High Precision Injection as well as a turbocharger powered via two exhaust ducts. Other elements of what BMW calls a 'progressive engine package' include the variable camshaft control system double VANOS and the fully variable valve control system VALVETRONIC.
