I bought a really clean 2012 Liberty back in May. I was not real happy with the initial acceleration since first gear is much taller than I would have wanted. However I do now notice if I give it about 1/3 of the gas pedal and hold it steady, when it reaches 3K rpm, there is a surge almost like a turbo engaging. After I pulled a heavy trailer for 1K miles it now holds off the upshift longer than before. This indicates the computer can learn driving style. Has anyone else noticed that?
Several sites list that 2012 liberty with 3.7 engine as doing 0-60 in ten seconds. Not impressive by today's standards. However it seems to me if first gear redlined at 30mph that Jeep could do 60 in 8 seconds. It is geared so high, if I mash the gas pedal, it will do 42 mph in first, 75 in second. That is some tall gearing. I have no intention of learning how fast third gear will redline.
AS far as I know the engine is factory stock.
