The Alpina D3 Touring (G21, facelift 2022) S 3.0 is a performance-oriented diesel station wagon based on the BMW 3 Series Touring (G21). Alpina, a Buchloe, Germany-based automotive engineering company, independently develops and manufactures high-performance vehicles, often based on BMW platforms. The D3 Touring, introduced after the LCI update to the G21 3 Series, represents a significant upgrade in both power and driving dynamics compared to the standard 3 Series diesel models. It caters to buyers seeking a blend of practicality, luxury, and spirited performance, offering a unique alternative in the premium estate car segment. The “S 3.0” designation indicates the engine variant and its associated performance enhancements.
Powertrain & Engine Architecture
At the heart of the D3 Touring S 3.0 lies the Alpina-tuned version of BMW’s 3.0-liter inline-six diesel engine, internally designated as the B57. This engine benefits from significant modifications, including larger turbochargers, an upgraded cooling system, and revised engine management software. The engine utilizes a sophisticated diesel commonrail fuel injection system, delivering precise fuel metering for optimal combustion. The valvetrain employs a Double Overhead Camshaft (DOHC) configuration with four valves per cylinder, maximizing airflow and contributing to the engine’s high output. The addition of a 48V mild-hybrid system provides a small power boost and enables smoother start-stop operation. The engine’s bi-turbo configuration, featuring two turbochargers, minimizes turbo lag and delivers a broad torque curve. Power is transmitted to all four wheels via an 8-speed automatic transmission, specifically Alpina’s Switch-Tronic gearbox, which offers quicker shift times and more responsive control compared to the standard BMW transmission.
Driving Characteristics
The D3 Touring S 3.0 delivers a remarkably refined yet potent driving experience. The 730 Nm (538.42 lb.-ft.) of torque, available from a low 1750 rpm, provides effortless acceleration in virtually any gear. The 8-speed Switch-Tronic transmission is well-matched to the engine’s characteristics, offering smooth and decisive gear changes. While not as overtly sporty as some gasoline-powered performance estates, the D3 Touring excels in providing a surge of power for overtaking and maintaining high speeds. The all-wheel-drive system ensures excellent traction in all weather conditions. Compared to the standard 3 Series diesel models, the D3 offers a noticeably more responsive throttle and a more engaging driving feel. The mild-hybrid system contributes to improved fuel efficiency and a smoother overall driving experience.
Equipment & Trim Levels
The Alpina D3 Touring S 3.0 comes generously equipped as standard. Interior appointments typically include premium leather upholstery, Alpina-specific interior trim (such as wood or carbon fiber), and sport seats. Standard features often include a panoramic sunroof, a premium sound system, and a comprehensive suite of driver-assistance systems. Optional extras can include upgraded leather options, individual paint colors, and bespoke interior customization options. The D3 Touring generally sits at the top of the 3 Series Touring range in terms of luxury and performance, offering a more exclusive and refined experience than even the fully-equipped BMW M340i Touring.
Chassis & Braking
The D3 Touring benefits from Alpina’s chassis tuning, which includes revised suspension components and optimized damping characteristics. The suspension setup aims to strike a balance between comfort and handling, providing a compliant ride while maintaining excellent body control. The front suspension utilizes a McPherson strut design, while the rear features a multi-link setup. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The D3 Touring typically features a more robust braking system than the standard 3 Series, with larger rotors and upgraded calipers.
Market Reception & Comparison
The Alpina D3 Touring S 3.0 has been well-received by automotive critics, who praise its blend of performance, luxury, and practicality. It is often lauded for its refined driving experience and its ability to deliver impressive speed without sacrificing comfort. Compared to other high-performance estate cars, such as the Audi S4 Avant or the BMW M340i Touring, the D3 offers a unique proposition with its diesel powertrain and Alpina’s distinctive tuning. While the M340i offers more outright performance, the D3 provides superior fuel economy and a more relaxed driving experience. The D3’s fuel economy of 6.9 l/100 km (34.1 US mpg) is significantly better than that of its gasoline-powered rivals.
Legacy
The Alpina D3 Touring S 3.0 (G21) represents a compelling offering in the high-performance estate car segment. The B57 diesel engine, in its Alpina-tuned form, has proven to be a reliable and durable powertrain. As a relatively low-volume production vehicle, the D3 Touring is likely to hold its value well in the used car market. Its unique combination of performance, luxury, and practicality makes it an appealing choice for discerning buyers seeking a distinctive and refined estate car.
