The Jeep Wrangler is priced attractively when considered alongside the Land Rover Discovery Sport, as the four-door Overland diesel comfortably undercuts the Discovery Sport HSE. However, purchase price is only part of the story.

Jeep Wrangler MPG & CO2

The most economical Wrangler (the three-door diesel) returns just 34.9mpg and emits 213g/km of CO2, resulting in road tax of £295 a year. If you choose the petrol engine you’ll be liable for top-rate road tax of £515 a year, while fuel economy drops to 25mpg. For comparison, an entry-level Land Rover Discovery Sport returns 57.6mpg and costs just £110 a year in tax. These efficiency figures make the petrol-engined Jeep hard to justify, particularly when its extra performance doesn’t really make the car more useable than the diesel. A petrol-engined Wrangler actually uses more fuel than a Ferrari California.

On top of this, the poor residual values of the Jeep mean that it’s likely to retain far less of its purchase cost in three years than the Land Rover Discovery Sport, potentially making for a painful experience when it comes to trade your Jeep in for a newer car.


With running costs like these, the Wrangler only makes sense if you’re going to use it off-road regularly. Unfortunately, this will prove harder on the Jeep’s mechanical components than life on the road, and regular replacement of worn parts may involve hefty bills.

A yearly service will be required for your Jeep Wrangler, with full advice provided in the owner’s manual to address specific mileage requirements.


Like all Jeeps, the Wrangler comes with a five-year/75,000-mile warranty, an upgrade to the old three-year/60,000-mile warranty that was offered until July 2018. It’s part of a campaign called ‘5-3-5’, so named because customers get a five-year warranty, a three-year servicing programme and five years of roadside assistance. This gives the Jeep’s warranty an edge over the three years offered for most rival brands. Hyundai matches Jeep’s five-year warranty (but with no mileage cap) and Kia provides an industry-leading seven years of cover.
