abstract:In aviation, an inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, but rarely more than six.
As for new offerings from Porsche, something based-on-but-smaller-than the Boxster (built on a VW platform, possibly with an inline-four engine), will come in the next year or two.
My test X3 xDrive35i was equipped with a 3.0-liter inline 6-cylinder engine with twin turbochargers, tuned to produce the magic numbers of 300 hp and 300 lb-ft of torque.
The 2.5-liter inline 4-cylinder gas engine and permanent magnet AC synchronous electric motor in the MKZ deliver 191 net horsepower, a modest amount of power for a 3, 752 lb vehicle.
