Jeep has yet to announce pricing for the new Wrangler, although it looks like you’ll need in excess of £40k for even the two-door model. And the Wrangler will be expensive to run, due to CO2 emissions of 195g/km and 202g/km for the two-door and four-door respectively. As for fuel economy, no version betters 40mpg on the official tests.
Again, specifications have yet to be confirmed, but all models should get a decent level of standard equipment. Although you get plenty of safety kit, automatic emergency braking isn’t on the list, even as an option.
