By slotting in two new, more efficient engines and adapting all its powertrains to an eight-speed automatic, Jaguar's shifted the gas mileage for the 2013 XF higher by a significant margin.
It's still not among the most economical sedans you can buy, but compared to last year's best-in-lineup ratings of 23 mpg highway, there's massive improvement.
By the numbers, the new turbo-four XF is rated at 19 miles per gallon city, 30 mpg highway, or 23 mpg combined. With the supercharged V-6 and with standard stop/start, it's closer than you think: the rear-drive version's pegged at 17/28 mpg or 21 mpg combined, and with all-wheel drive, at 16/26 mpg or 19 mpg combined.
Though last year's normally aspirated base V-8 is gone, it's still worth comparing it to this year's supercharged V-8s. Last year the base engine was rated at 16/23 mpg, with supercharged versions at 15/21 mpg. For 2013, the new transmission nets both supercharged models the same EPA figures: they're 15/23 mpg, or 18 mpg combined.
