Alpina B3: generations, engines, and what to check when buying used
The Alpina B3 is a unique sports version of the BMW 3 Series, crafted by Alpina since the 1990s. We look at the generations — from the E36 to the G20 — engines, differences from standard BMWs, and what to check before buying a used B3.
Alpina B3 in brief
The Alpina B3 is a BMW 3 Series sedan or estate that Alpina transforms into a more powerful and comfortable version. Unlike BMW M models, Alpina focuses not on track performance, but on a fast, comfortable, and high-quality touring car with distinctive interior.
The B3 is rarely found in the used market, so prices and availability vary greatly. It's crucial to thoroughly check if the car is genuinely made by Alpina, not just dressed up with similar parts.
Which generation to choose
Earlier generations (E36, circa 1993–1998; E46, circa 2001–2004) are valued as collectible cars. They're simple but of a bygone era, so the key is their technical condition and rust.
The E90/E92 generation B3 Bi-Turbo (2007–2013) features a 3.0-litre twin-turbo engine with around 360–400 hp and is the most popular choice for those seeking a more affordable entry into the Alpina world. The F30/F31 generation (2013–2019) is more powerful — around 410–440 hp, while the G20/G21 (from 2020) is even more modern, with around 460 hp.
If a modern interior and technology are important to you, go for the G20/G21. If you want more affordable pricing and classic driving, consider the E90/E92 or F30/F31.
Engines and gearboxes
Modern B3 versions use a 3.0-litre six-cylinder twin-turbo engine. Power output has increased: around 360–400 hp for E90/E92, around 410–440 hp for F30/F31, and around 460 hp for G20/G21. The latest versions also come with all-wheel drive.
The most common gearbox is the automatic Switch-Tronic, which allows you to shift gears using the steering wheel paddles. In older models, you might find manual gearboxes, but these are rare.
What to check when buying a used B3
First, verify the car's authenticity: Alpina has a unique serial number, usually displayed on a special plate. Ask the seller for documents and check the VIN against Alpina records.
Review the service history — oil changes, brakes, tyres. Alpina uses special wheels and tyres, so replacements can be expensive. Also, check the condition of the turbo and cooling systems, especially in older versions.
Test the electronics, multimedia, and assist systems. Also, assess the bodywork, lights, and interior trim, as original Alpina parts are pricey.
