Skylarks have had five different engines over this 5-year period, starting with a 120-horsepower, 2.3-liter Quad OHC four and, in the Gran Sport, a 3.3-liter V6. Also optional in base models, the V6 whipped out 160 horsepower. The Quad OHC dropped to 115 horsepower in Skylark's second season. Both engines were connected to a 3-speed automatic transmission. No 4-speed automatic was available until 1994. A 3.1-liter V6, making 155 horsepower, replaced the 3.3-liter that year and was available only with the new electronic 4-speed automatic, which could be installed in other models. The base engine zoomed to 150 horsepower for '95, adopting a dual-overhead-cam configuration and Quad 4 designation. A counter-rotating balance shaft reduced vibration. Yet another base engine went into 1996 models, the Twin Cam, displacing 2.4 liters and developing the same 150 horsepower as the previous 2.3-liter four.
