With sporty and economical powertrains, an 8-speed automatic transmission and available all-wheel drive, the 2015 Jaguar XF lineup is no longer just a niche luxury car-- it now applies to a much wider swath of upscale sedan shoppers. The base 2.0 model and its 30-mpg highway rating is surprisingly fuel-efficient, while the high-performance XFR-S at the top end of the lineup offers blistering acceleration, with its 550-hp rating. In addition to its graceful-yet-aggressive look and strong performance, the XF's opulent cabin appointments remain a standout.
