Jaguar is adding a new 3.0-liter supercharged V-6 engine to its powertrain lineup. The 2013 Jaguar XJ will now benefit from the addition of a smaller, 335-hp high-performance engine that is more fuel-efficient than the 2012 XJ’s 5.0-liter V-8. The 2013 Jaguar XF will also benefit from this addition, as well as a turbo-four-cylinder engine. These engines will replace the V-8 in those models, but the 5.0-liter engine will still find a home in the 2013 Jaguar XK.
The 2013 XJ and XF will also get newer transmissions: Out goes the six-speed automatic, in comes the more efficient eight-speed automatic with a start-stop function that is said to get 14 percent better fuel economy over the current six-speed. Better fuel economy will be a welcome feature, the entry-level 2012 XJ gets an EPA estimated 16 mpg in the city and 23 on the highway, mediocre numbers that especially resonated after the ultra-high fuel prices experienced earlier this year.
The XJ is Jaguar’s five passenger rear-wheel drive sedan, and competes with the likes of the Mercedes-Benz S-Class, the BMW 7 Series, and the Audi A8. The Jaguar XJ is noted for having an opulent interior cabin. More details are expected on the 2013 Jaguar XJ later this summer.
