2013 Alpina B5 Sedan (F10 LCI, Facelift 2013) Dimensions, Size & Specs

The curb weight of the Alpina B5 Sedan (F10 LCI) is 1970 kilograms (4344 pounds), which is the weight of the vehicle without passengers or cargo but including necessary fluids. The maximum permissible weight is 2470 kilograms (5445 pounds), indicating the total weight the car can safely handle including occupants, luggage, and fuel. This balance ensures strong performance and stability while supporting the practicality of carrying passengers and gear.

The luggage capacity of the Alpina B5 Sedan (F10 LCI) stands at 520 liters (approximately 18.4 cubic feet). This volume is generous for an executive sedan, allowing comfortable transport of luggage, groceries, or sports equipment. Its ample trunk space makes the B5 Sedan practical for both daily use and longer journeys, complementing its luxury and high-performance attributes.

Yes, the Alpina B5 Sedan (F10 LCI) fits into a standard residential garage. With a width of 1860 mm (73.2 inches) excluding mirrors and 2102 mm (82.8 inches) including mirrors, along with a length of 4913 mm (193.3 inches) and height of 1469 mm (57.8 inches), it comfortably fits in typical garages. However, drivers should be aware of the opened mirror width when maneuvering in tighter spaces to avoid potential scrapes.

Compared to its predecessor, the Alpina B5 Sedan (the pre-facelift F10 and earlier models), the F10 LCI facelift introduced in 2013 came with slight refinements in dimensions and weight. The length of 4913 mm and curb weight of 1970 kg reflect a slightly more refined and efficient build. While overall size remained largely consistent to maintain the executive sedan class standards, design updates enhanced aerodynamics and luxury, resulting in a more modern and comfortable driving experience without significant changes to footprint or mass.

The Alpina B5 Sedan (F10 LCI) rides on staggered 20-inch wheels, with front rims sized at 8.5J x 20 and rear rims at 10J x 20. The corresponding tire sizes are 255/35 ZR20 for the front and 295/30 ZR20 for the rear. This configuration supports excellent grip and handling characteristics suitable for the car's high-performance nature while contributing to its sporty aesthetic.

With mirrors opened, the width of the Alpina B5 Sedan (F10 LCI) increases to 2102 mm (82.8 inches), which is considerably wider than the body width of 1860 mm (73.2 inches). This wider footprint requires drivers to be cautious in narrow city streets, tight parking spaces, and when navigating through congested areas. While this width is typical for performance sedans with aerodynamic mirrors, it may require more careful maneuvering than smaller vehicles, especially in older or compact urban garages.

When compared to similar executive performance sedans such as the BMW M5 (non-Alpina), Audi RS7, or Mercedes-AMG E63 of the same era, the Alpina B5 Sedan (F10 LCI) offers comparable dimensions. Its length of 4913 mm and width around 1860 mm fall into the typical range of large sedans in this segment. However, Alpina’s approach focuses on blending performance with luxury refinement rather than maximum aggression, resulting in slightly more understated exterior dimensions paired with high-quality aerodynamic enhancements and luxurious interior space.

With a curb weight of 1970 kg (4344 lbs), the Alpina B5 Sedan (F10 LCI) balances solid build quality with dynamic agility. The relatively high mass, due to its luxurious equipment and reinforced performance components, contributes to a planted and stable driving experience at high speeds, while Alpina's tuning of suspension and chassis ensures that handling remains sharp and precise. The well-engineered weight distribution lends confidence in corners and during quick acceleration, striking an effective balance between comfort and sportiness.

The Alpina B5 Sedan (F10 LCI) shares its interior dimensions with the BMW 5 Series of the same generation, providing generous room for five adults. Its length and width support comfortable front and rear seating, with ample headroom (height 1469 mm) and legroom due to its executive sedan class. The design emphasizes luxury and passenger comfort, with high-quality materials and advanced ergonomics. Rear passengers particularly benefit from the spacious cabin, making it suitable for both daily commuting and long-distance travel.
