Inside, the changes are more subtle with the XF gaining a new steering wheel, revised seats, a modified instrument panel and optional 1200W Bowers & Wilkins premium sound system. In North America, the 2012 XF continues with the existing engine lineup that includes a 385HP 5.0-liter naturally-aspirated V8, a 470HP 5.0-liter supercharged V8 and a 5.0-liter supercharged V8 with 510HP in the XFR.

In Europe and other markets, however, Jaguar is introducing the 2.2-liter four-cylinder AJ-i4D turbo diesel, which is a development of the Ford unit found in the Land Rover Freelander. The oil burner puts out 190HP and 450Nm of peak torque, and is linked to a new 8-speed automatic transmission. Jaguar says that with this engine, the XF reached 60mph (96 km/h) in 8.0 seconds en route to a top speed of 140 mph (225 km/h), while returning a 52.3mpg UK (equal to 43.6 mpg US or 5.4 lt/100 km) on the EU combined cycle, making it the most economical Jaguar ever. According to the automaker, it emits 149g/km of CO2 and is Euro Stage V compliant.
