The 2011 Jaguar XJ Supercharged is designed to be a performance luxury sedan and it doesn’t disappoint. It offers the luxury buyer a level of comfort unmatched by the competition, and gives the enthusiastic driver excellent performance. The XJ gets a 385 horsepower 5.0-liter V-8 that is adequate for the average luxury buyer.
But for the performance oriented driver, the Supercharged model gets the same 5.0-liter V-8 engine but with a supercharger that adds 85 horsepower and 40 foot-pounds of torque. With 470 horsepower and 424 pound-feet of torque, the Supercharged XJ shaves one second off the 0-60 mph benchmark to less than 5 seconds.
Around town the XJ Supercharged is serene, quiet, and feels like a luxury limousine. The big V-8 is smooth and stealthy as a big cat stalking its prey, extremely quiet at cruising speeds or loping around town. Its large 20-inch wheels soak up most road harshness and only the nastier bumps can be felt. The XJ seems to be a good balance between luxury car-like ride and sports sedan driving characteristics.
But as soon as you dip into the throttle and the supercharger begins to spin, this big cat comes alive. The first thing you hear is the supercharger beginning to spool up with just enough sound, but absent of the whine characteristic of most turbocharged engines. The driver needs to make sure there is ample clear road ahead because this cat is going to run fast.
The driver feels the immediate Gs that push into the seat as early as 2,000 rpm and continues to get stronger as the 470 horsepower and 424 pound-feet of torque gets close to redline. The XJ blows past sixty mph in a staggering 4.4 seconds. But the incredible acceleration of the 2011 Jaguar XJ L Supercharged is a result of more than just all those ponies under the hood. Jaguar engineers trimmed the weight of the XJ with the use of a lighter aluminum structure underneath the beautiful exterior.
The incredible available power is partly due to the flawless six-speed transmission. The ZF tranny just seems to anticipate when to select the right gear for the driver’s level of aggressiveness. When in sport mode, the ZF actually remaps shift points depending on driver input. This transmission is so fast, that the driver forgets to use the paddle shifters. In all of its moves, the powerful XJ feels more agile than its 4,310 pounds suggest.
Tomorrow we’ll give a complete summary of our week with the XJ Supercharged.
