2025 Alpina D4 Gran Coupe (G26, facelift 2024) Dimensions, Size & Specs

The curb weight of the Alpina D4 Gran Coupe is 1945 kg (approximately 4290 lbs), with a maximum weight rating of 2420 kg (around 5335 lbs). This substantial mass is supported by Alpina’s engineering to ensure agile handling and strong performance. The weight influences acceleration, braking, and cornering dynamics, contributing to a stable and comfortable ride. Combined with Alpina’s suspension tuning and powertrain enhancements, the weight is well balanced for a dynamic driving experience without compromising comfort or safety.

The luggage capacity of the Alpina D4 Gran Coupe is 470 liters (16.6 cubic feet) under normal conditions, which is quite generous for a luxury coupe, allowing for ample space for luggage or groceries. When the rear seats are folded down, the capacity increases significantly to 1290 liters (45.6 cubic feet). This flexibility makes the car practical for carrying larger items or additional cargo while maintaining the sleek coupe profile. The spacious trunk adds to the car’s usability, making it suitable for longer trips or everyday use.

Yes, the Alpina D4 Gran Coupe fits comfortably into a standard garage, though its width with mirrors opened—2073 mm (81.6 inches)—requires attention. Most standard garages have widths of approximately 2400 mm to 3000 mm (94.5 to 118 inches), so door mirrors must be considered when parking. The car’s height of 1440 mm (56.7 inches) and length of 4792 mm (188.7 inches) are typical for high-end coupes and should fit within standard garage lengths and clearances. However, owners should ensure their garage door and interior space can accommodate the open mirror span safely.

The Alpina D4 Gran Coupe comes equipped with 10J x 20 front rims and 8.5J x 20 rear rims, paired with tire sizes of 285/30 ZR20 on the front and 255/35 ZR20 on the rear. These wide tires and large rims provide excellent grip and stability, enhancing cornering performance and braking efficiency. The staggered tire sizes also contribute to the car's sporty stance and handling dynamics by optimizing surface contact and weight distribution. Such specifications reflect Alpina’s focus on performance-oriented driving and precise handling.

Compared to its predecessor, the 2025 Alpina D4 Gran Coupe (G26 facelift) maintains a similar footprint but with refined styling and slight dimensional tweaks for improved aerodynamics and interior comfort. The 4792 mm length (188.7 inches) is aligned closely with earlier models, ensuring that its dynamic stance is preserved. Width and height remain largely similar but improvements in width with mirrors (now 2073 mm) reflect evolving design cues, focusing on road presence and stability. These minor changes enhance driving experience while retaining the core coupe characteristics.

In the luxury coupe segment, the Alpina D4 Gran Coupe stands out with its length of 4792 mm (188.7 inches), which is competitive but slightly longer than many rivals such as the standard BMW 4 Series Gran Coupe and the Audi A5 Sportback. Its width of 1850 mm (72.8 inches) and 2073 mm (81.6 inches) with mirrors open is comparable to competitors, offering a good balance between interior space and road presence. The luggage capacity of 470 liters (16.6 cubic feet) is generous, often surpassing other luxury coupes, providing practical everyday usability alongside sporty aesthetics.

The Alpina D4 Gran Coupe has a roof load capacity of 75 kg (approximately 165 lbs), which allows for the attachment of roof racks, bike carriers, or cargo boxes while staying within manufacturer safety limits. This load capacity is typical for coupes and provides versatility for users who require additional cargo options, particularly for outdoor activities or travel. It's important to not exceed this weight to maintain vehicle stability and safety during driving.

The Alpina D4 Gran Coupe (G26 facelift 2024) is classified as a coupe but with four doors, combining sporty aesthetics with practicality, aimed at drivers who desire performance and luxury without sacrificing daily usability. It targets enthusiasts who appreciate Alpina’s blend of BMW engineering and bespoke tuning, offering enhanced power, refined ride quality, and exclusivity.

Its 1440 mm (56.7 inches) height allows for a sleek roofline without compromising headroom significantly. The 470-liter (16.6 cubic feet) trunk volume, expandable to 1290 liters (45.6 cubic feet) with rear seats folded, underlines the car's practicality. These dimensions give passengers ample legroom and cargo versatility, blending sportiness with daily usability.
