• The XJ will add a supercharged V6 with an 8-speed automatic transmission for 2013
  • The mid-size XF will add that engine and a new turbocharged four-cylinder
  • The updated sedans will go on sale this fall

Several major revisions are coming to Jaguar's lineup for the 2013 model year. The automaker recently announced the updates, which include a new transmission and two new engines designed to improve fuel economy in the XF and XJ sedans.

For Jaguar's flagship XJ luxury sedan, a new 3.0-liter V6 highlights the updates for 2013. Slotting below last year's 385-horsepower 5.0-liter V8 as the base engine in the XJ's lineup, the 3.0-liter V6 is supercharged to produce 340 hp and 331 lb-ft of torque. While the 5.0-liter V8 will remain an available engine choice, the V6's new eight-speed automatic transmission is sure to boost the XJ's fuel economy while preserving the sedan's muscular acceleration.

The XF will get the new 3.0-liter V6 for 2013, and Jaguar's smaller sedan is also adding yet another new powerplant: a 2.0-liter turbocharged 4-cylinder, developed when the luxury brand was owned by Ford. Jaguar has yet to announce the engine's horsepower and torque numbers, but the same engine produces 240 hp and 250 lb-ft of torque in Range Rover's recently released Evoque compact SUV. It is also used in several Ford models, including the Edge, Escape, Explorer, Taurus and the 2013 Fusion sedan.

For industry observers and shoppers interested in a luxury car, the changes to Jaguar's lineup will come as no surprise, since many other luxury automakers are also downsizing their engines. BMW and Porsche currently offer V6-powered variants of their full-size 7 Series and Panamera luxury sedans, while Audi recently released a 4-cylinder version of its mid-size A6. Mercedes-Benz has been slower to cut its cylinder count but has a wider range of fuel efficient diesel-powered models than any of its luxury competitors.

According to Jaguar, the revised 2013 XF and XJ models will begin arriving in dealerships this fall. The automaker says it will also announce more updates for its 2013 models when it reveals pricing for the new model year.

What it means to you: If you're interested in a Jaguar but crave better gas mileage, wait for the 2013 model year.
