V8 ditched in favor of V6 on the 2013 Jaguar XJ

Jaguar’s big cat, the XJ, was a snarling beast of car, capable of fierce V8 brutality, and velvet-glove luxury. The top-shelf Jag has an aluminum exoskeleton, which makes it the lightest, and possibly the nimblest car in its class (i.e. Potentate Haulers). But all of that British charm is about to change somewhat, as Jag’s big cat gets, well, neutered for 2013.

The change comes in the form of a 335-hp supercharged V6 supplanting the standard 5-liter 8-pipe noise organ, found in the 2012 Jaguar XJ. There will also be a new ZF 8-speed automatic, with an integrated Start/Stop function. Along with re-calibrated springs, dampers, and a reprogrammed damper control computer. These changes amount to a fuel economy rating of 18 city / 26 hwy / 21 combined, and supposedly, the cushiest ride ever seen in a Jag.

Part of the current Jaguar XJ ‘s draw was that angry sounding 385-hp 5.0 V8. You know, the engine that powered Jeremy Clarkson along, as he raced God on Top Gear. It was a fantastic powerplant, but we assume they’ll keep it around for the 2013 Jaguar XJ Supersport.
