The Jeep Wrangler Unlimited CRD (only available in the UK) scores a [whopping 28mpg](http://www.jeep.co.uk/jeep/pdf/wranglervsdefender.pdf “UK Wrangler CRD”). That’s huge, and if it were available in the US, I guarantee that Jeep wouldn’t be able to keep them on dealer lots.
The only questions are when, and if Jeep will ever bring this model to the United States. I think it would be silly of them not to, but there are probably reasons that would prevent this, that we don’t know. Either way, it will be exciting to watch it unfold.
