The fuel economy in our long-term Jaguar XE isn’t great — perhaps because the XE is so much fun to drive

I’ve mentioned in previous reports that despite putting my best, greenest shoes on, I’ve not been able to match the combined 67.3mpg which Jaguar says our long-term XE should manage.

No surprise there, you might say, because everyone knows that most cars fail to live up to the advertised figures in the long run.

I’ve been thinking, though: by how much does the XE miss its claimed figures by in the real world? To find out, I lent our car to sister magazine What Car?’s in-house team of True MPG testers, who assess the economy of cars over a variety of real-world conditions.

Jaguar says our test car — a 2.0-litre Ingenium diesel with 178bhp — should return 55.4mpg in the city and more than 76mpg on the motorway. However, our tests returned 38.4mpg and 51.6mpg respectively. That’s an average of 33% behind what Jaguar suggests.

The bottom line is that our XE will return a real-world average of 45.0mpg. That number tallies (just) with what we’ve been able to achieve. Now, enter the BMW 320d, which on the same tests returned an average of 51.7mpg — an 18% dip on what BMW claims. The Mercedes-Benz C-Class C220 d returned 51.0mpg, 26% behind its claimed figures. The Jaguar still beats the new Audi A4 2.0 TDI, which returned 44.4mpg in the True MPG tests, 32% behind what Audi claims.

So, you’ll spend more time at the pumps in the XE than you will in the BMW and Mercedes. Having driven the other two, though, I’m inclined to say you’ll have more fun driving the Jaguar than you will its German rivals. The Jaguar feels playful, even with this relatively mid-range diesel engine.

I recently opted to drive four friends home after an evening out, and although the journey started with complaints about rear legroom, it ended with everyone saying how much they enjoyed the Jaguar. The XE can still pull its weight with considerable gusto, even with all five seats filled, while keeping everyone comfortable and unflustered.

The eight-speed automatic transmission is a real gem, delivering smooth and precise changes. It’s so good that I rarely take control myself.

Its seats are comfortable and on these cold winter mornings I’ve been loving the fact they’re heated. At £435, Jaguar’s Cold Climate Package may seem expensive, but it adds heated front seats, a heated steering wheel, and a heated windscreen. If I were to buy an XE, I’d tick this option first.

Talking of freezing, a few weeks ago we experienced a problem with the XE’s infotainment system crashing. After a trip back to Jaguar’s HQ for a laptop consultation though, the issue is sorted (if this were a customer car, it would mean a free trip to the dealer). It’s been running faultlessly ever since, but I have heard from another XE driver who discovered the same problem on his rental car.

Our Verdict

Jaguar XE

Jaguar's first attempt at a compact exec saloon is good - very good. But can the XE hold off the BMW 3 Series and Alfa Romeo Guilia to retain its crown?

An interesting comparison with the rivals real MPG. That shows that the car makers have spent the last ten years honing their cars for doing well in the EDC labs while the real MPG has not changed much. If any!

Hey fadyady, out of interest is that mpg what the dash displays or what you have worked out from miles provided from the amount of fuel and distance yourself?

I unfortunately have no faith in the read outs!

I have seen 65mpg in mine, and I know someone with be base engine who got 71mpg driving down to London. It is of course very dependant on the driving style and road speed.

Also shows what an under developed, p1ss poor unit the Ingenium is too.

Not just jaguar but all brands. How can they claim these figures which are way off. It's a total con, yes everyone knows the figures are a joke but why do we have to put up with it. Why don't n cap or someone do their own test.

I can't see how it's not false advertising, do we know the airbags work or do they not deploy in certain exact conditions and manufacturers can't be held responsible.

Looking at that photo, the XE's proportions look ridiculous. And I'm just not convinced that 3 adults would really be comfortable on that back seat.

Maybe to please old-school customers for whom long bonnet = large engine = powerful performance? No wonder with such an elongated bonnet there leaves little room in the cabin for rear seat passengers. Lets hope that electric cars will significantly change the proportion of cars. But even for ICE cars the rational proportions of the original A class and Audi A2 did not attract many customers.

I have watched countless reviews of VAG cars and now also Jaguars where they report ridiculously low CO2 values and their real world is a million miles away. Your comments highlight it but you gloss over it with a warm glow. When will someone start taking these companies to task about lies about consumption. It seems all reviews about the new ingenium diesel engine report it as gruff and noisy. I have a F30 320ED which also is gruff and noisy. It has however averaged 60.1mpg in 144,000 miles over 4 years. It is about to be replaced and I know I wont see fuel consumption this good for a long while... especially given it's excellent performance!

I drove Wapping to Llandudno last Friday cruised at 70 on the motorways, and stuck to the limits when the sat nav took me off the M6 and via Nantwich and Wrexham on A roads to avoid a jam. 270 miles in 4 and a half hours and my trip computer showed 52.2mpg. I was consciously driving smoothly to try and keep the average up, but I kept pace with traffic. A subsequent fill up corrected the mpg to 49.9 - I managed to get 24.6 litres into the tank. My vehicle? A 1.8 tonne 2008 7 seat Hyundai Santa Fe 2.2 diesel with a 5 speed auto. Hardly cutting edge technology. Where is the progress?

Seems we are all getting fed up with the manufacturers blatantly misleading mpg figures.It's misleading and fraudulent.Whenever I look at a car's advertised mpg, I automatically discount it by 1/3rd - that can't be acceptable,can it? They need some serious fines to get the message across.
