The Alpina B3 Touring (F31 LCI), specifically the S 3.0 variant with 440 horsepower and the Switch-Tronic automatic transmission, represents a unique blend of high performance and practicality. Produced from 2017 to 2019, this model is based on the BMW 3 Series Touring (F31) but extensively modified by Alpina, a renowned German automotive engineering company. The “LCI” designation refers to the Life Cycle Impulse, or facelift, applied to the F31 3 Series in 2015, incorporating updated styling and technology. The B3 Touring S 3.0 occupied the top performance tier within the B3 Touring range, offering a significant step up in power and refinement compared to the standard B3d diesel models.

Powertrain & Engine Architecture
At the heart of the B3 Touring S 3.0 lies Alpina’s version of the BMW N55 inline-six engine. While based on the BMW unit, Alpina significantly modified it with two custom-developed turbochargers, larger intercoolers, a revised cooling system, and a bespoke engine management system. These enhancements boosted the engine’s output to 440 horsepower and 660 Nm (486.79 lb-ft) of torque. The engine utilizes direct fuel injection and double-VANOS variable valve timing for optimized performance and efficiency. The “Switch-Tronic” transmission is a ZF 8-speed automatic, further refined by Alpina with quicker shift times and a more responsive feel. It features a Sport mode and the ability to manually shift gears via steering wheel-mounted paddles.
Driving Characteristics
The B3 Touring S 3.0 delivers a compelling driving experience. The combination of the powerful engine and the quick-shifting transmission results in impressive acceleration – 0 to 60 mph in around 4.1 seconds and a top speed of 188 mph. The rear-wheel-drive configuration provides a balanced feel, while the Alpina-tuned suspension offers a comfortable ride without sacrificing handling precision. Compared to the standard 3 Series Touring, the B3 S 3.0 feels significantly more potent, with a broader torque curve and a more engaging driving experience. The automatic transmission, while smooth, is noticeably more responsive in Sport mode, holding gears longer and downshifting quickly under braking. Compared to the B3d diesel variant, the S 3.0 offers a more traditional, high-revving performance character.
Equipment & Trim Levels
The B3 Touring S 3.0 came generously equipped as standard. Interior features included Alpina-specific leather upholstery, unique wood trim, and Alpina-branded instrumentation. Standard equipment also included a premium sound system, navigation, and a host of driver-assistance systems. Optional extras included a panoramic sunroof, upgraded leather options, and various customization options through Alpina’s bespoke program. The interior generally maintained the BMW 3 Series layout but with Alpina’s signature touches of luxury and refinement.
Chassis & Braking
Alpina made significant changes to the chassis to handle the increased power. The suspension was retuned with stiffer springs and dampers, and the car sat slightly lower than the standard 3 Series. The braking system was upgraded with larger discs and calipers for improved stopping power. The B3 Touring S 3.0 featured ventilated discs on all four wheels and came standard with ABS and stability control. The steering was also recalibrated for a more direct and responsive feel.
Market Reception & Comparison
The Alpina B3 Touring S 3.0 was well-received by automotive critics, who praised its blend of performance, luxury, and practicality. It was often seen as a compelling alternative to more mainstream performance wagons like the Audi RS4 Avant. Fuel economy was respectable for a car of its performance, averaging around 29 US mpg in combined driving. Reliability was generally good, benefiting from the underlying BMW engineering and Alpina’s meticulous attention to detail. However, maintenance costs were higher than those of a standard 3 Series due to the specialized components and Alpina’s recommended service intervals.
Legacy
The Alpina B3 Touring S 3.0 (F31 LCI) remains a desirable vehicle in the used car market. Its combination of rarity, performance, and practicality makes it a sought-after model for enthusiasts. The N55 engine, while not without its potential issues (such as oil leaks and cooling system vulnerabilities), is generally considered robust when properly maintained. The Switch-Tronic transmission has also proven to be reliable. Values have generally held up well, reflecting the car’s unique position in the performance wagon segment. It represents a high point in Alpina’s history, showcasing their ability to create truly special and engaging automobiles.
