ALPINA B10

The quickest way to misunderstand an ALPINA B10 is to treat the badge as a complete specification.

It is not. B10 is a model-family name that ALPINA reused across several very different cars. Depending on the period, a B10 might have a naturally aspirated straight-six, a twin-turbo straight-six or a V8. It might be rear-wheel drive or all-wheel drive, a saloon or a Touring, manual or automatic. And there is an easily missed exception right at the beginning of the story: B10 was not confined entirely to the BMW 5 Series.

That matters when you are reading an advert. “ALPINA B10” tells you where to start; the chassis era and derivative tell you what the car actually is.

B10 at a glance

This is why a single “B10 specification” table is more likely to confuse than help. The useful comparison is derivative against derivative.

The first B10 was an E28 — but that is not the whole first chapter

ALPINA's own historical E28 page gives a firmer starting point. It records the BMW ALPINA B10 3,5 on the BMW 535i (E28), with production from July 1985 to December 1987. The factory page lists ALPINA engine type B10, 3,430 cc, six cylinders, 192 kW / 261 hp and 346 Nm.

That page also includes an important identification caveat: ALPINA says B10 engines were delivered separately for conversions of BMW cars. An ALPINA B10 engine therefore does not, by itself, establish that the complete car was produced as a BMW ALPINA B10.

The unofficial ALPINA-Archive reports 77 E28 B10 3.5 cars. ALPINA's official E28 page does not give a production count, so 77 remains a specialist-archive figure rather than a factory-certified total.

But the same archive also records a B10 3.5 Coupé under the E24 6 Series, with 44 produced in its model index. That is a small detail with a large consequence: it makes the common claim that every B10 was a 5-Series-based car too absolute.

It also explains why a clean B10 family tree is harder than it first appears. The name is an ALPINA model designation, not simply BMW's chassis code with another badge attached.

For older UK cars there is another wrinkle. The archive contains separately identified Sytner-produced examples alongside the Buchloe-numbered cars. That is a warning against taking one headline production count and using it to answer every question about how many B10s existed in a particular market.

E34 is where B10 becomes a family rather than a single recipe

If the E28 introduced the name, the E34 demonstrates why the suffix matters.

ALPINA's own E34 model history lists five distinct B10 groups: 3.5/1, BiTurbo, 3.0 Allrad, 4.0 and 4.6. Those are not cosmetic editions of one underlying specification. The manufacturer history now supplies the programme windows and headline technical data for each branch; the unofficial ALPINA-Archive remains useful for attributed production counts and register detail.

The B10 3.5/1 continued the large naturally aspirated straight-six idea. The B10 Bi-Turbo went in a very different direction, using the BMW 535i as its starting point and adding two turbochargers plus extensive drivetrain, suspension and braking changes. Road & Track's later retrospective records a 1989 Geneva Motor Show debut after two years of development and says 507 were built. The car's period reputation became one of the defining chapters in ALPINA history, but it was only one branch of the E34 B10 range.

Then the family widened again.

The B10 3.0 Allrad was based around the BMW 525ix and brought all-wheel drive into the B10 story. The archive records both saloon and Touring versions. The B10 4.0 and later B10 4.6 moved to V8 power, again with saloon and Touring cars represented in the records.

So even within a single BMW generation, “B10” can describe materially different engines, drivetrains and body styles.

What the E34 production records do — and do not — tell us

The current unofficial archive index gives the following produced totals:

These figures are useful for scale, but they should be read as specialist archive counts, not silently promoted into factory-certified totals. Older archive pages sometimes divide saloon and Touring production differently, and exact dates can also differ from later historical reporting.

The B10 Bi-Turbo is a good example of why source hierarchy matters. ALPINA's own model history dates the programme from August 1989 to March 1994 and lists the 535i basis, B7/5 engine type, 3,430 cc, 265 kW / 360 hp and 520 Nm. Road & Track independently supports the 1989 Geneva debut and the 507-car total. Because ALPINA's page does not publish a production quantity, 507 remains corroborated historical and specialist evidence rather than a factory-ledger total.

The E39 B10 split into six-cylinder and V8 branches

The E39 B10 has a direct TMJC connection through the 1999 B10 3.3 manual discussed below.

The E39 era did not begin with one definitive specification either. The unofficial archive describes the B10 V8 and B10 3.2 as separate early branches, followed by the B10 3.3 and later B10 V8 S. Its current E39 index also separates a later B10 V8/1 production group, another reason not to compress every E39 V8 into one line of data.

The six-cylinder progression is relatively easy to follow. The archive describes the B10 3.2 as a 1997 introduction and says it was replaced by the B10 3.3 in 1999. It records the 3.2 with a five-speed manual gearbox. The 3.3 kept a five-speed manual option and, according to the archive, gained optional Switch-Tronic with the facelift in 2001.

The V8 path developed in parallel. The archive describes the B10 V8 as based on the BMW 540i and documents output changes during its life before the V8 S took the idea further. This is the point at which a seller simply writing “E39 B10” becomes particularly unhelpful: a 3.2, 3.3, V8 and V8 S are not interchangeable cars.

Why B10 dates can look inconsistent

A historical ALPINA can have several dates that answer different questions:

• BMW assembly;
• ALPINA completion or assembly;
• motor-show introduction;
• first registration;
• start or end of a particular derivative batch.

Those are not necessarily the same month or even the same calendar year.

That distinction shows up in the E39 evidence. The current B10 V8 model history in the specialist archive describes a March 1997 introduction, while an older production register starts an early V8 batch in December 1996. Those statements do not automatically contradict one another: one can describe public introduction while another describes production activity.

It is safer to identify the exact derivative and, where a particular car matters, work from its build documentation rather than using registration year alone to infer specification.

How to tell whether a B10 is really what it claims to be

ALPINA wheels, stripes, spoilers and interior parts are desirable enough to have been fitted to many ordinary BMWs. A numbered plaque is useful evidence, but it should not be treated as the whole authentication process either.

ALPINA CLASSIC offers a Delivery Certificate for almost all BMW ALPINA cars built between 1978 and 2025. Depending on the vehicle record, it can document:

• the ALPINA model designation;
• the BMW series;
• the ALPINA chassis number;
• the ALPINA production number;
• the BMW chassis number;
• the engine number;
• the production month.

That is a much stronger starting point than deciding from wheels or badges.

There is an important qualification in ALPINA CLASSIC's own wording: the certificate records the original delivery condition. It does not certify that the car remains wholly original today, nor does it certify its present condition or value.

For a car being bought as a collector-grade B10, the useful question is therefore not just “does it have a plaque?” It is whether the identity, chassis information, engine information, production number and surviving paperwork agree — and then whether the car in front of you still corresponds to that documented identity.

That distinction matters especially with cars that have had engine changes, gearbox conversions, replacement interiors or later ALPINA parts fitted.

A TMJC example: the 1999 B10 3.3 manual V491EBC

TMJC has handled a 1999 E39 B10 3.3, registration V491EBC. The surviving TMJC-syndicated advert records it as right-hand drive with a 3.3-litre petrol engine and five-speed manual gearbox.

That places it within one specific branch of the much wider B10 family. It does not mean “B10” generally means 3.3 litres or manual transmission.

An older advert for the same registration reports production plaque number 47. That is useful provenance evidence, but it is still an advert-derived claim until matched to factory documentation. ALPINA CLASSIC's Delivery Certificate service gives a route to verifying production number, chassis and engine information from the manufacturer-side vehicle file.

For the exact derivative, see the B10 3.3 Saloon Manual page.

Do not ask “what is the B10 specification?”

A better sequence is:

1. establish which BMW/ALPINA era the car belongs to;
2. identify the full B10 derivative, not just the B10 badge;
3. establish market and body style;
4. check gearbox and drivetrain against that derivative;
5. verify the individual car's production identity and documentary history.

That approach avoids several common errors at once. It prevents E39 3.3 figures being copied onto a V8, stops a Bi-Turbo being treated as representative of every E34 B10, and makes room for unusual branches such as the E34 3.0 Allrad or the early E24 B10 3.5 Coupé.

The B10 name is interesting precisely because it changed. Over its life it shows ALPINA repeatedly reworking BMW's executive-car ingredients rather than preserving one fixed engineering formula.
