There are actually two supercharged powerplants in Jaguar’s 2013 XF line of cars. The Jaguar’s new 3.0-liter V6 is pressurized to produce 340 horsepower and 251 ft-lbs of torque. This engine supplants the 385-horsepower/380 ft-lb normally aspirated 5.0-liter V8 previously powering the small Jaguar saloon (that’s sedan for those of you not fluent in English-English).
Then there is the engine powering the “official” Jaguar XF Supercharged, the blown 5.0-liter V8. The subject of this review, we’ll get to the particulars of that car’s engine a bit later because there is another new powerplant available to Jaguar XF intenders for the 2013 model year. The base 2013 Jaguar XF model employs a turbocharged 2.0-liter four (the same engine the Land Rover Evoque uses to good effect). The turbocharged four delivers 240 horsepower and 251 ft-lbs of torque.
The other two supercharged Jaguars are the XFR and the XFR-S. Both use the same 5.0-liter V8, but are tuned for different levels of output. The XFR gets 510 horsepower out of the engine, while the XFR-S gets 550 horsepower. Both carry over from the 2012 model year.
Another new development for 2013 models is the addition of all-wheel drive to the list of Jaguar XF attributes. Those seeking four-wheel propulsion will get the 3.0-liter supercharged V6 as standard equipment. All of Jaguar’s supercharged engines use statrt/stop technology in an effort to improve their fuel economy.
The other new XF mechanical development for the 2013 model year is the incorporation of an all-new eight-speed automatic transmission across the board for the Jaguar sport sedan. The wider array of engine choices is expected to broaden the appeal of the Jaguar considerably by offering two versions of the car with better fuel economy, less weight, and a lower starting price.
