Since BMW's acquisition of ALPINA in 2022, the Buchloe-based manufacturer has operated as a wholly-owned subsidiary — but the cars remain distinctly different from their M counterparts. The B3 Touring is perhaps the best example of why ALPINA still matters.
Power & Delivery
The B3 uses a reworked version of BMW's B58 3.0-liter inline-six — notably not the M division's S58. ALPINA's engineers extract 462 horsepower and 516 lb-ft of torque through unique turbocharger modifications, revised intercooling, and bespoke ECU calibration. The power delivery is linear and relentless, prioritizing mid-range torque over peak horsepower. It's the opposite philosophy to the M3's top-end rush.
Ride & Refinement
Where the M3 is calibrated for the track, the B3 is tuned for the autobahn. ALPINA's signature suspension setup uses softer spring rates and retuned adaptive dampers that absorb imperfections the M3 transmits. The ALPINA-specific 20-inch wheels wear higher-profile tires than the M3's optional 19s, further improving ride quality.
The exhaust note reflects this philosophy too. Where the M3 pops and crackles, the B3 produces a deep, refined howl that builds with the revs. It's satisfying without being aggressive.
The Interior Difference
ALPINA interiors feature hand-finished Lavalina leather, unique stitching patterns, and the signature blue-and-green instrument cluster. The B3 receives a steering wheel that's thinner than the M3's, with a more traditional shape. Production numbers remain limited — each B3 spends additional days on the line for ALPINA-specific assembly and quality checks.
