2013 Jaguar XJ Drops V8 for Supercharged Six, Loses 168 HP

Jaguar announced details on its 2013 XJ sport sedan today including the news that its previous 5.0-liter V8 would be replaced with a 3.0-liter supercharged V6.

Often noted for its all-aluminum architecture, the lightweight sedan will benefit from improved fuel economy thanks to its smaller engine and a new eight-speed automatic transmission with standard start-stop technology. The 3.0-liter supercharged V6 offers 335 hp and is the same powerplant that will propel the upcoming F-Type roadster.

According to Jaguar, the upcoming model will also have an more refined, better performing suspension. Despite the changes for better performance, the company also took measures to improve ride quality with re-calibrated spring and damper tunes and remapped damper software.

Much the same as many other automakers, Jaguar is taking steps to offer performance and fuel economy in the same package. In other manufacturer’s cases, that hasn’t meant such a drastic power sacrifice, but given how light the XJ is for it’s size, it might not matter all that much, especially with a supercharger to deliver initial boost.

In 2011, sales increased for the car, though it remains to be seen if that will be true with the smaller engine. Then again, a jump to 30 mpg on the highway over the company’s estimated 25 last year probably won’t hurt either.
