BMW Alpina B3 Touring (G21)

A BMW Alpina badge carries a certain expectation, and the catalogue numbers show a more interesting picture than a simple search for outright dominance. The Alpina B3 Touring (G21) sits in the top 60% of the 600-car catalogue for power, with 462 bhp, but its real distinction is not a single headline statistic. It is the unusual combination behind those figures: an inline-6, twin-turbocharged engine paired with AWD, a pairing shared by only 8 cars in the catalogue.

That combination places the B3 Touring in a narrow part of the collection. Only 33 of 600 cars use an inline-6 layout, and just 14 are twin-turbocharged inline-6 cars. The B3 Touring therefore stands apart through its specific engineering mix rather than simply chasing the highest numbers. Its 3.0-litre engine produces 700 Nm of torque, helping deliver a 0-100 km/h time of 3.8 seconds and a top speed of 303 km/h. Those figures place it faster than 333 cars in the catalogue for acceleration and give it a top speed rank of 265 out of 600.

The B3 Touring also occupies an interesting position when cost enters the equation. With a used price of £65,000, it ranks 385 of 600 for price, making it more expensive than 215 cars in the catalogue. Its cost per bhp is £141, which reflects a car where the appeal is not only the power figure, but the particular specification that delivers it. The 48 BMW entries in the catalogue provide context, yet this Alpina variant separates itself through the rarity of its six-cylinder, twin-turbocharged AWD formula.

As a 2020 model from Germany, the B3 Touring brings together the character of a four or five seater saloon with performance figures that place it firmly among capable machines in the collection. Its 303 km/h top speed and 462 bhp show that it has the numbers expected of a serious performance car, while its catalogue position explains why those numbers matter in a broader setting.

The expectation attached to the BMW Alpina badge is that there should be something distinctive behind it, and the catalogue confirms that distinction in a quieter way. The B3 Touring is not defined by being the highest-ranked car in any single measure. It earns attention because, within a garage of 600 choices, it represents a rare intersection of inline-6 character, twin-turbocharged performance and AWD capability that only a small group can match. It is the kind of choice that changes the shape of a collection by adding a specification few others share.
