Yahoo Autos Fuel Economy and Driving Range
Fuel Economy Rating:
Fuel economy flips the XE engine lineup’s script. Those who prioritize fuel economy in their sports sedan likely will gravitate toward the 20d diesel model, which is EPA rated for up to 42 mpg highway. There is a large chasm between the thrifty diesel and the gasoline inline-four and V-6 engines, which offer merely average economy.
What’s New for 2018?
Although two new gasoline-powered four-cylinders join the lineup this year wearing 25t and 30t badges, the diesel remains the most efficient of the bunch. We put the 247-hp version of the 2.0-liter four-cylinder through our real-world fuel-economy testing and were disappointed by its performance. However, we also had the chance to run an all-wheel-drive version of the diesel-burning 20d through the same test, and it overdelivered a result of 42 mpg, 2 mpg more than its EPA rating.

2017 Jaguar XE
Somehow Jaguar was unable to coax any more efficiency from the gas four-cylinder than it extracts from the 33-percent-larger V-6. Both the 25t and 35t XE trims are estimated by the EPA to return 21 mpg in the city and 30 mpg on the highway. The all-wheel-drive 35t’s figures are lower by 1 mpg (the gas four is only available with rear-wheel drive). The odd parity in fuel consumption between the two engines is yet another reason to consider skipping the standard four-cylinder for the quick V-6.
Fuel Economy Ratings Compared
We’ve devised our own fuel-economy test in an attempt to replicate how most people drive on the highway. Our procedure entails a 200-mile out-and-back loop on Michigan’s I-94 highway. We maintain a GPS-verified 75 mph and use the cruise control as much as possible to mimic the way many drivers behave during long trips.
Just as the six-cylinder, all-wheel-drive XE’s EPA-estimated fuel economy lags behind others in the class, so too does its performance in our 200-mile real-world economy test. The 26 mpg we recorded falls short of the EPA’s 29-mpg highway estimate. Meanwhile, the diesel lived up to its billing with a 42-mpg showing. That last number is quite good, but for context, BMW’s gas-powered four-cylinder engine saw 41 mpg in our real-world test and is much quicker and infinitely smoother.
