2022 Alpina D4 Gran Coupe (G26) Dimensions, Size & Specs

The Alpina D4 Gran Coupe (G26) has a curb weight of 2020 kg (4452 lbs), which positions it as a relatively hefty vehicle in the luxury coupe segment. This weight includes standard equipment and fluids necessary for operation. The substantial curb weight reflects its solid construction, advanced technology, and performance components. Despite its weight, the D4 maintains strong dynamic capabilities and driving performance due to efficient powertrain tuning and chassis engineering.

The maximum permissible weight of the Alpina D4 Gran Coupe is 2420 kg (5335 lbs). This indicates the total combined weight of the car, passengers, cargo, and any additional equipment. The difference between curb weight and maximum weight gives an approximate payload capacity of around 400 kg (882 lbs), which allows for multiple passengers and a reasonable amount of luggage or gear without overload. This balance supports comfortable everyday usability without compromising driving performance.

The luggage capacity of the Alpina D4 Gran Coupe stands at 470 liters (approximately 16.6 cubic feet) with the rear seats in their standard position, providing sufficient room for everyday grocery trips, luggage, or gear. When the rear seats are folded down, the available luggage space significantly increases to 1290 liters (about 45.6 cubic feet). This expanded space makes it much more versatile, ideal for carrying larger items, sports equipment, or multiple suitcases, making the car functional beyond its luxurious and sporty character.

Standard residential garages typically measure around 2400 mm (94.5 inches) wide and 4800 mm (189 inches) deep, though sizes vary by region. With a length of 4792 mm (188.7 inches), width of 1850 mm (72.8 inches) excluding mirrors, and a height of 1440 mm (56.7 inches), the Alpina D4 Gran Coupe fits comfortably inside standard garage dimensions. However, the width with mirrors opened is 2073 mm (81.6 inches), so care must be taken when maneuvering the vehicle into garages with limited clearance, especially regarding mirror folding mechanisms.

This generation features staggered rim sizes: 10J x 20 inches for the rear and 8.5J x 20 inches for the front, paired with wide tires sized 285/30 R20 at the rear and 255/35 R20 at the front. These dimensions enhance grip, stability, and responsiveness, especially during high-speed cornering and dynamic driving. The wider rear tires provide improved traction for the rear-wheel or all-wheel-drive configuration, while the lower profile tires contribute to sharper handling. Overall, this setup balances comfort and sporty dynamics characteristic of Alpina tuning.

Compared to the previous Alpina D4 Gran Coupe generation, the G26 model is slightly larger and more refined. The current generation increased in length and width marginally to improve interior space, comfort, and road presence. While specific predecessor dimensions vary, the G26’s 4792 mm length and 1850 mm width reflect a modernized design approach emphasizing aerodynamics and luxury. The growth in size also translates into increased luggage capacity and improved rear passenger comfort, aligning with evolving consumer expectations for premium coupes.

When compared to other luxury performance coupes like the BMW 4 Series Gran Coupe and Audi A5 Sportback, the Alpina D4 Gran Coupe offers competitive dimensions. Its length of 4792 mm (188.7 inches) is on par or slightly longer than many rivals, offering ample interior and cargo space. Its width of 1850 mm (72.8 inches) and height of 1440 mm (56.7 inches) strike a balance between sporty aesthetics and cabin comfort. The luggage capacity up to 1290 liters (45.6 cubic feet) with folded seats is notably spacious for its class, making it not just a performance vehicle but also a practical choice.

The Alpina D4 Gran Coupe (G26) features a 4-door coupe layout that combines sporty coupe styling with the practicality of rear doors for easier access to rear seats. The interior is designed to comfortably seat four passengers with adequate headroom and legroom, thanks to its length and optimized cabin packaging. The lower height of 1440 mm (56.7 inches) contributes to the sleeker silhouette but still accommodates comfort through smart seat design and interior ergonomics. This generation focuses on blending performance-oriented design with usability for daily driving and longer trips.

The Alpina D4 Gran Coupe (G26) stands out through meticulous engineering combining luxury, performance, and advanced technology. Key highlights include its sophisticated suspension tuning for sporty but compliant ride quality, distinctive Alpina styling cues, and high-quality interior materials. The 2022-2024 models incorporate the latest driver assistance technologies and infotainment upgrades, integrating seamlessly with the vehicle’s dynamic capabilities. Its balanced size and sculpted aerodynamic design optimize both aesthetics and functional performance, making it an appealing choice in the premium coupe segment.
