The curb weight of the 2008 Jaguar XJ (X358) ranges from 1533 kg to 1653 kg (approximately 3,379 to 3,644 pounds), depending on trim and equipment options. The maximum allowable weight ranges from 2183 kg to 2283 kg (about 4,813 to 5,033 pounds), which includes passengers, cargo, and fuel.

The luggage capacity for the 2008 Jaguar XJ (X358) sedan is 470 liters (16.6 cubic feet). This is competitive within the luxury sedan class, offering ample space for suitcases and groceries, making it practical for both daily use and longer trips.

Standard single-car garages commonly measure around 2.4 to 2.7 meters (7.9 to 8.9 feet) in width and 4.8 to 6 meters (15.7 to 19.7 feet) in length. With its width of 1860 mm (73.2 inches) folded and length of 5091 mm (200.4 inches), the Jaguar XJ (X358) fits comfortably in a typical garage, but the opened mirror width of 2104 mm (82.8 inches) requires careful handling when parking.

Compared to its predecessor, the Jaguar XJ X350 (produced from 2003 to 2007), which measured approximately 1875 mm (73.8 inches) wide with mirrors folded, the X358 model is slightly narrower at 1860 mm (73.2 inches). This subtle reduction provides a slightly more manageable width for urban driving without compromising interior space.

In terms of length, the 2008 Jaguar XJ (5091 mm or 200.4 inches) is comparable to the BMW 7 Series and Mercedes-Benz S-Class of the same era, which generally range between 5,050 mm to 5,200 mm (198.8 to 204.7 inches). The XJ is slightly narrower than these competitors but maintains a lower height, contributing to its sleek profile. Overall, the XJ offers a blend of commanding road presence with refined dimensions suitable for luxury sedan buyers.

The 2008 Jaguar XJ (X358) comes equipped with either 9J x 20-inch rims paired with 255/35 ZR20 tires or 8.5J x 19-inch rims with 255/40 HR19 tires. Larger 20-inch wheels enhance handling and sporty aesthetics but can slightly reduce ride comfort due to lower profile tires. The 19-inch setup offers a balance of comfort and performance, contributing to the sedan's refined driving dynamics.

The roof load limit for the 2008 Jaguar XJ (X358) is 75 kg (approximately 165 pounds). This means that any roof-mounted cargo carriers, bike racks, or luggage boxes must not exceed this weight to ensure safe driving dynamics and avoid damage to the roof structure. It's essential to consider this limit when planning to carry large or heavy items on the roof.

The 2008 Jaguar XJ (X358) stands at a height of 1462 mm (57.5 inches), which is relatively low for a full-size luxury sedan. This low profile enhances aerodynamic efficiency and contributes to a sporty, sleek appearance. It also lowers the center of gravity, improving handling characteristics. However, drivers should verify garage or parking structure heights to ensure adequate clearance.

The XJ (X358) generation brought a noticeable reduction in weight compared to the X350, thanks to increased use of aluminum in the body structure, resulting in curb weights starting around 1533 kg (3,379 lbs) versus the heavier previous generation. This contributed to improved fuel efficiency, agility, and performance. Design-wise, the X358 updated the classic Jaguar styling with modern touches, offering a more streamlined and contemporary look while retaining its luxury sedan identity.
