There used to be a 2.4-liter four-cylinder base engine and a 2.8-liter turbocharged four-cylinder diesel engine option for the Liberty. By 2007, both four-cylinder options were axed, leaving the 3.7-liter V6 as the only engine available for this Jeep model.
In Jeep Liberty’s final year, it added a bit of tech flair with rear parking sensors as an available upgrade, but the same V6 engine remained right up until the end. The Liberty comes standard with rear-wheel drive (RWD), but four-wheel drive (FWD) is also an option.
