The 2.2-litre diesel has a reasonable amount of punch, getting the Wrangler up to motorway speeds without too much fuss, although the much lighter two-door version unsurprisingly feels a lot sprightlier than the four-door model. It's a lot quieter than the previous 2.8-litre diesel, although it still sounds gravelly even while cruising and transmits more than a few vibrations through the controls.
