BMW 3 Series Alpina B3 D3 Sedan 2013

The B3 Bi-Turbo was unveiled at Geneva in March 2013, while the D3 Bi-Turbo made its public debut at the Frankfurt Motor Show in September. That sequence helps explain why the two names are often listed together in catalogues covering the F30 3 Series. The B3 also carried Alpina’s familiar blue instrument dials and used transmission-control buttons mounted behind the steering wheel rather than conventional paddles.

No reliable production figure specific to the 2013 sedan has been established in the sources consulted. Alpina operated as a small-series manufacturer, with cars completed according to combinations of engine, body style, drivetrain, and customer-selected equipment. Production numbers sometimes quoted for the D3 Bi-Turbo family or for the wider Alpina 3 Series range generally cover several years, body styles, and markets, so they cannot be used to identify the number of sedans built in 2013. This distinction matters because a total covering an entire model family should not be presented as the production figure for either the B3 or D3 sedan alone.

Automotive reviewers generally praised the B3 Bi-Turbo for combining very high performance with comfort and understated styling. Tests by What Car? and Auto Express highlighted the engine’s strength, the effectiveness of the automatic transmission, and the chassis’s ability to remain usable every day, while noting that the car cost substantially more than a conventional 3 Series. The D3 attracted attention for its exceptionally strong torque and unusual pace for a diesel sedan. Reviews also made an important distinction: Alpina’s tuning philosophy emphasized high-speed touring and composure rather than the sharper, more overtly aggressive character associated with a BMW M car.
