2005 Alpina B7 (E65/E66L) Dimensions, Size & Specs

The Alpina B7 (E65/E66L) weighs between 1970 kg to 1990 kg (about 4344 to 4387 lbs) curb weight, which is the vehicle's weight without passengers or cargo but with standard equipment and fluids. The maximum weight, which includes the car fully loaded with passengers and cargo, ranges from 2510 kg to 2530 kg (approximately 5535 to 5577 lbs). This reflects the robust build and performance-oriented engineering of the B7, balancing luxury features with a strong powertrain and reinforced suspension components.

The luggage capacity of the Alpina B7 (E65/E66L) is 500 liters, which equates to roughly 17.7 cubic feet. This amount of cargo space is quite competitive within the luxury sedan segment, providing ample room for suitcases and other belongings needed for long trips or everyday use. Compared to other full-size luxury sedans of its era, this capacity is about average, balancing passenger comfort and trunk usability without compromising the sleek, executive design of the vehicle.

Standard residential garages generally measure around 2.4 to 2.7 meters (8 to 9 feet) in width and about 5.5 meters (18 feet) in length. Given the Alpina B7 (E65/E66L) has a width of 1.9 meters (74.8 inches) and a length ranging from 5.03 meters to 5.17 meters (198 to 203.5 inches), it will fit into a typical garage with some clearance. However, the length approaching or slightly exceeding 5 meters means owners should ensure sufficient garage length, especially to accommodate entry and exit space comfortably. The height of 1.48 meters (58.3 inches) presents no issue for standard garages.

The Alpina B7 (E65/E66L) was a successor to the earlier B7 based on the BMW E38 7 Series. Compared to the predecessor, the E65/E66L model is longer and wider, with its length ranging up to 5170 mm compared to the previous generation's slightly shorter length around 5 meters. The width of 1900 mm also shows a modest increase, contributing to a more spacious interior and a stronger road presence. The E65/E66L's modernized design philosophy emphasized more interior space and technology upgrades, resulting in a heavier vehicle but also one that feels more refined and contemporary on the road.

In comparison to similar luxury performance sedans from the mid-2000s, such as the Mercedes-Benz E-Class AMG or Audi S8, the Alpina B7 (E65/E66L) is generally longer and sometimes a bit wider. Its length reaching up to 5170 mm (203.5 inches) puts it on the larger end of the spectrum, effectively competing with flagship sedans like the Mercedes-Benz S-Class and Audi A8. This size advantage allows for enhanced rear passenger comfort and luggage space. The width of 1900 mm (74.8 inches) is typical for these vehicles, balancing stable handling with interior room. Overall, the Alpina B7 stands out for combining substantial size with high-performance elements and exclusive Alpina craftsmanship.

The Alpina B7 (E65/E66L) usually comes equipped with large 21-inch rims — 10J x 21 and 9J x 21 sizes. The tires fitted are typically 285/30 R21 for the rear and 245/35 R21 for the front. These wide, low-profile tires and large wheels contribute to a sporty stance and improve handling precision, cornering grip, and braking performance. However, their low profile also means that ride comfort can be firmer compared to smaller wheels with higher-profile tires. The 21-inch rims underscore the B7’s blend of luxury and performance, giving it a distinguished and aggressive look while enhancing dynamic capabilities.

The Alpina B7 (E65/E66L) has a height of 1480 mm (58.3 inches), which is relatively low for a luxury sedan, contributing positively to aerodynamic efficiency by reducing drag and improving fuel efficiency and high-speed stability. A lower profile also enhances handling by lowering the center of gravity. Despite the reduced height, the interior is designed to maintain generous headroom for passengers, especially with the long-wheelbase variant (E66L), which prioritizes rear passenger comfort. This height strikes a balance between sporty driving dynamics and the spaciousness expected in a high-end luxury vehicle.

The Alpina B7 (E65/E66L) has a curb weight between 1970 kg to 1990 kg (4344 to 4387 lbs), which is typical for a high-performance full-size luxury sedan with numerous luxury amenities and reinforced mechanical components. When compared to contemporaries like the Mercedes-Benz S55 AMG or Audi S8, which weigh in a similar range, the B7’s weight reflects its blend of luxury equipment and the powerful, turbocharged V8 engine tuning by Alpina. Though heavy, the weight is managed carefully through performance-oriented suspension and braking components that maintain driving agility despite the vehicle’s size and mass.

The Alpina B7 (E65/E66L) offers a spacious and luxurious interior, with the E66L variant featuring an extended wheelbase specifically designed to increase rear passenger legroom and overall cabin space. This long-wheelbase model increases rear-seat comfort significantly, making it well-suited for chauffeured driving or long-distance travel. The combination of extended length up to 5170 mm (203.5 inches) and careful interior packaging ensures ample headroom, shoulder room, and legroom. This luxurious interior space is complemented by high-quality materials, advanced infotainment systems, and comfort features characteristic of Alpina’s attention to detail.
