It's not every day that you see a diesel Jaguar XF on these shores. In fact, at least officially, there's only one. And it just completed a cross-country road trip that took it from New York to Los Angeles.

The trip kicked off last week in the Big Apple and just wrapped up earlier this week in LA. Over the course of the eight-day journey across eleven states, three time zones and 2,884 miles, the bone-stock XF with the 2.2-liter diesel four averaged a highly impressive 62.9 miles per gallon (even better than the previous European tour), hitting a peak of 67 mpg as it approached the West Coast.

Not too shabby, especially for a luxury sedan that is, at the end of the day, anything but a lightweight. Check out the updated image gallery to see how the oil-burning Jag progressed, and follow the jump for the official press release.

A British team has crossed North America, from New York to Los Angeles, in an XF 2.2 Diesel averaging an incredible 62.9 mpg over 2,884-miles – making it the most efficient Jaguar ever created.

Finishing in Los Angeles, California on Monday, November 14, the journey – the equivalent of travelling from London to the Sahara - took in 11 states, three time zones and eight days. Yet the XF only required four stops for fuel – its peak economy of 67 mpg being achieved on the penultimate day of the trip.

Paul Alcock, XF Project Manager, Jaguar Cars, who was present throughout the journey, commented: 'This project was designed primarily to test the potential economy of the XF 2.2. The incredible figures achieved by the car were accomplished through making every element of the new XF as efficient as possible – from its aerodynamics to its four-cylinder 2.2-litre diesel engine linked to an eight-speed gearbox. The whole XF team is incredibly proud of what's been achieved and it's a graphic demonstration of the strength, engineering integrity and efficiency of the car.'

Driven by independent testers, David and Alexander Madgwick, the XF 2.2 was a scrupulously standard UK registered, right-hand drive vehicle. In the course of the coast to coast adventure, the car maintained an average speed of 53 mph incorporating a multitude of real-life scenarios including the busy roads exiting New York and, towards the end of the trip, entering Los Angeles, road works, high winds and a climb to 7,275 feet above sea level.

Despite such efficiency, the XF 2.2 maintains the levels of performance and efficiency expected of a Jaguar. Capable of seating five adults in comfort, it's equipped with leather trim as standard as well as a touchscreen display and climate control. The XF is capable of accelerating from rest to 60 mph in 8.0-seconds before reaching a top speed of 140mph.

The project has been broadcast live on Twitter and on Facebook as Jaguar's Senior Press Officer, Faye Goldstraw, travelling in a support vehicle, charted the progress of the car as it crossed America.

      Very cool. SO, When does the USA get this?! Price it right and it will be on my short list.
        • 3 Years Ago
        I bet it's 62.9 mpg UK since the press release is for UK readers. So 52 mpg US. In Europe, this 2.2L diesel is priced a bit less than half of what an XFR costs, or 31% less than the 5.0 V8. This is by far the cheapest member of the XF family. (Just to give you an idea of the pricing)

      I'd like to see how the V6 diesel compares.
      • 3 Years Ago
      This is essentially the same PSA/Ford unit used in the Mondeo 2.2 TDCi, which gets comparatively similar fuel economy (over 60mpg imperial on the highway) and very much in line with BMW's 2 litre diesels.
      • 3 Years Ago
      Wow, that's amazing. I remember the three-car diesel comparo on Top Gear a couple of years ago, with Jezza driving a diesel XJ, which was getting over 50mpg. I'd say bring 'em here, but then, would U.S. Jag buyers embrace them? I wonder.
        • 3 Years Ago
        I wonder how much fuel they had left after their trip

      If we are going to hit the crazy cafe requirements in the next 20 years we are going to need more diesel sedans here. I'd like to get the TSX diesel (Euro Accord) in the USA. I think it gets a combined 46mpg (US). It would be slower but it wouldn't really feel slow b/c of the readily available torque. It's not very often that I wind up my car to redline anyway.

      Were they hyper-miling or driving normal?
        • 3 Years Ago
        Probably some light hypermiling, but nothing extreme. The highway (extra-urban in Euro-speak) rating for this car is 58.9mpg(also Imperial Gallons). So, the 62.9mpg achieved here isn't a huge increase over that. Granted, the European economy ratings tend to overestimate a bit as well, so there is that. Diesels also tend to do their best work on the highway also and this is a relatively lower-powered engine for the size and class this car is in. I do beleive a true hypermiler could squeeze out far more than this test provided. It seems to me based on the distance covered over time and the economy they saw, that they weren't driving with specific attention to saving fuel. I'd bet they just flipped on the cruise control at the speed limit and went on their merry way. Note how the AB staff achieves highway mileage into the 50's in their long-term Jetta TDI by doing largely the same thing (perhaps with a slightly heavier foot though). It's a fairly easy thing to do with most modern diesels.

      This car really needs to come to the US....
      • 3 Years Ago
      I've seen a couple people mention it in posts, but I really do think the article's text should be updated to say that it's 62.9 UK mpg.... and about 52 US mpg. Awesome car and mileage though; diesels rock!
      • 3 Years Ago
      Dammit....that engine should be in the Land Rover Evoque or in Jag's sedans here
      • 3 Years Ago
      Would love to see an assortment of nice turbo diesel luxury come to the states. Especially with the kind of MPG numbers even hybrids seem to dream of. Didn't Clarkson take the S-Type diesel 800 miles on one tank on Top Gear UK?
        • 3 Years Ago
        That was an Audi and yes it was amazing!
      • 3 Years Ago
      Toyota Pri--what was that little boxy thing called again? THANK YOU, JAGUAR.
