Powertrain & Engine Architecture
At the heart of the D5 Touring S 3.0 lies Alpina’s version of the BMW N57D30 inline-six diesel engine. While based on the BMW architecture, Alpina extensively modifies the engine to enhance performance and durability. These modifications include specifically designed pistons, a larger turbocharger, and an upgraded cooling system. The engine utilizes a sophisticated diesel commonrail fuel injection system, delivering precise fuel metering for optimal combustion. The valvetrain features four valves per cylinder, contributing to efficient gas exchange. The engine’s output of 388 hp and a substantial 800 Nm (590 lb-ft) of torque is a testament to Alpina’s engineering prowess. The engine is paired with a ZF 8-speed automatic transmission, branded as ‘Switch-Tronic’ by Alpina. This transmission is specifically tuned for smooth and responsive shifts, and features a sport mode for more aggressive gear changes.
Driving Characteristics
The D5 Touring S 3.0 delivers a remarkably refined and potent driving experience. The high torque output, available from as low as 1750 rpm, provides effortless acceleration in virtually any gear. The Switch-Tronic transmission complements the engine perfectly, offering seamless gear changes and contributing to a relaxed cruising experience. While not as overtly sporty as some of its gasoline-powered rivals, the D5 offers impressive performance, achieving 0-60 mph in approximately 4.4 seconds. The all-wheel-drive system ensures excellent traction and stability, particularly in adverse weather conditions. Compared to the standard BMW 5 Series Touring with a comparable diesel engine, the Alpina D5 offers a noticeably more responsive throttle, quicker acceleration, and a more engaging driving feel.
Equipment & Trim Levels
The Alpina D5 Touring S 3.0 is generously equipped as standard. Interior appointments include premium leather upholstery, Alpina-specific interior trim (often featuring wood or carbon fiber accents), and sport seats. Standard features also include a comprehensive infotainment system with navigation, a premium sound system, and a suite of driver-assistance technologies. Optional extras included features such as a panoramic sunroof, upgraded leather options, and individual color choices. The D5 sits at the top of the 5 Series Touring range, offering a more luxurious and exclusive experience than other trims.
Chassis & Braking
The D5 Touring benefits from a chassis tuned by Alpina for enhanced handling and ride comfort. The suspension features stiffer springs and dampers compared to the standard 5 Series, reducing body roll and improving responsiveness. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The braking system is further enhanced by ABS (Anti-lock Braking System) and other electronic stability control systems. The standard wheel and tire combination is 255/35 ZR20 front and 295/30 ZR20 rear, providing excellent grip and handling.
Market Reception & Comparison
The Alpina D5 Touring S 3.0 was generally well-received by automotive critics. It was praised for its blend of performance, luxury, and practicality. Reviewers noted the engine’s impressive power and torque, the transmission’s smoothness, and the car’s comfortable ride. Compared to other high-performance estates, such as the Audi RS6 Avant or the Mercedes-AMG E 63 Estate, the D5 offered a more understated and refined experience, with a focus on long-distance comfort and efficiency. Fuel economy was also a strong point, with combined figures around 34.1 US mpg being competitive for a vehicle of this performance level.
Legacy
The Alpina D5 Touring (G31) S 3.0 has proven to be a reliable and durable vehicle. The BMW-derived diesel engine is known for its longevity, and the Alpina-specific modifications further enhance its robustness.
