Roberto Ravaglia’s DTM title in 1989 in the M3 E30. The overall Le Mans win in 1999 with the V12 LMR. Bruno Spengler’s DTM championship in 2012. Nine wins at the Macau Guia. These achievements belong to Schnitzer Motorsport in Freilassing.
They belong not to AC Schnitzer in Aachen. These are two different companies, founded 700 kilometres apart, twenty years apart — connected by exactly one person. And because both carry the same name, the confusion is still passed on today in classified ads, forums and occasionally in the trade press.
The timing for a clarification is unfortunate and yet fitting: On 20 March 2026, AC Schnitzer announced it would cease business operations by the end of the year. And Herbert Schnitzer, the person connecting both companies, died on 5 June 2026 on his 85th birthday.
Who is who
| Schnitzer Motorsport | AC Schnitzer | |
|---|---|---|
| Location | Freilassing, Upper Bavaria | Aachen, Neuenhofstraße |
| Founded | 1967 | 1987 |
| By | Josef (1939–1978) and Herbert Schnitzer (1941–2026) | Willi Kohl and Herbert Schnitzer |
| Business | Racing, BMW works team | Accessories and conversion programme for road vehicles |
| Legal entity | independent | Business division of KOHL automobile GmbH |
| End | BMW ended the partnership on 04.12.2020, liquidation in 2021 | Closure by the end of the year 2026 announced |
The division of roles in Freilassing: Josef Schnitzer drove and developed, Herbert handled the business side. Josef died 1978 in a traffic accident on the way to a race. Karl “Charly” Lamm became team principal.
A footnote for anyone digging deeper: Sources disagree on Karl Lamm — the English Wikipedia calls him the stepfather of the Schnitzer brothers, German motorsport sources call Charly Lamm their half-brother. These are two people with the same first name: Karl Lamm senior, whose business became the BMW dealership in 1964, and his son Karl “Charly” Lamm, who joined the team in 1971 and died at the end of 2018.
A finding that speaks for itself
We reviewed the German-language obituaries for Herbert Schnitzer from June 2026 — bimmertoday, SPEEDWEEK, Alte Schule. None mention AC Schnitzer in Aachen. Conversely, the detailed company histories of Schnitzer Motorsport likewise do not mention the Aachen firm.
The two narrative strands run completely separately in the trade press. Anyone who only reads one side never learns that the other exists — and that is exactly where the confusion originates.
What does “AC” stand for?
According to common understanding, for Aachen, derived from the vehicle registration plate. The German and English Wikipedia say so, BMW Scene Live says so. However, we could not find it documented on any company website — neither ac-schnitzer.de nor KOHL spell out the abbreviation. So it is well founded, but hearsay.
One interpretation occasionally read is in any case wrong: the founding company name was “AC Schnitzer automobile Technik” — which would give “aT”, not “AC”.
No manufacturer — and why that matters when buying
This is where the second distinction lies, one that is often blurred: ALPINA is a recognised vehicle manufacturer with its own chassis number. Hartge has been since 1985, with the world manufacturer code W09. AC Schnitzer is not.
The evidence is clear-cut and comes from the brand’s best-known vehicle: the ACS3 CLS auctioned in 2025 carries the chassis number WBSBF91000JC39743. WBS is the code of BMW M GmbH. The car formally remained a BMW M3.
This fits with the company’s own presentation: AC Schnitzer’s homologation page is a download area for parts certificates, ABE and EC component approvals — not for vehicle type approvals. The business consisted of more than 2,500 aftermarket options on the principle of “everything can – nothing must”: engine, exhaust system, suspension, wheels, aerodynamics, interior. Petrolicious aptly calls the complete vehicles “halo demonstration vehicles” — showcase pieces, not regular business.
What follows from this: With an ALPINA or a Hartge, the chassis number settles the question of authenticity. With AC Schnitzer it cannot. An Aachen conversion cannot be proven through the paperwork. What remains is the numbered plaque, the non-retrofittable substance — and invoices.
One qualification belongs here: there was also official closeness to BMW. Collecting Cars describes the ACS3 C30 based on the E46as a “manufacturer-approved conversion”, which BMW itself listed as an option in sales brochures at the time. It was sold through authorised BMW dealers.
The ACS3 CLS — and four different production numbers for one car
CLS stands for Coupé Lightweight Silhouette — a deliberate nod to BMW’s CSL tradition. Introduced in 1993 based on the E36 M3.
| ACS3 CLS | CLS II | |
|---|---|---|
| Engine | S50B30, 3.0 l | S50B32, 3.2 l |
| Power | 320 PS at 7,000/min | approx. 350 bhp |
| Weight | approx. 1,300 kg, around 160 kg below standard | — |
| 0–100 km/h | 5.5 s | approx. 5 s |
| Lightweight construction | Bonnet, bumpers, widened wings, door trims, seats in carbon-Kevlar | additionally roof and rear spoiler, complete rear bench |
And now the production numbers. Four figures are in circulation:
| Figure | Who says it |
|---|---|
| 75 | Top Gear 2019, Sports Car Digest, the Bring a Trailer listing 2025 (“#7 of a reported 75”) |
| 14 | AUTO BILD KLASSIK 2021 — explicitly labelled unconfirmed; The Classic Valuer |
| single digit, at most around 15 | Autoblog, citing experts on the model’s history |
| two | one previous owner, quoted at bmwblog — “14, if you add up CLS and CLS II” |
But the real finding is a different one, and it is the most interesting part of this piece: All four figures come from the same car. Top Gear 2019 (Hong Kong, three seats, £120,000), AUTO BILD KLASSIK 2021 (Hong Kong, chassis No. 7), Bring a Trailer December 2025 (plaque “#007”, produced February 1995) — throughout, it is car number 7.
So the range from 2 to 75 does not arise because different cars were counted differently. It arises because a single vehicle was described repeatedly over six years — and each report adopted a different figure.
One detail on the car itself supports the confusion. On the boot lid of the car in the photo below it reads “S3 II CLS” — the designation of the second stage, on a vehicle that the photographer explicitly lists as “#7 of 14”. The photo was taken in August 2025 at the Lime Rock Historic Festival in Connecticut, a good hour’s drive from North Salem, where the car auctioned in December was registered. It stands to reason that it is the same vehicle; we cannot prove it.
The models of the E-series
| Model | Basis | Year | Engine / power |
|---|---|---|---|
| ACS7 | 7 Series E32 740i | 1987, IAA debut | 4.0 l V8, 291 PS |
| ACS3 Sport | M3 E30 | 1989 | 2.4 l S14 bored out, approx. 245 PS, 250 km/h |
| ACS3 CLS / CLS II | M3 E36 | from 1993 | see above |
| V8 Roadster | Z3 2.8i | 1997 | V8 from the 540i, 310 hp |
| ACS3 C30 Kompressor | 330Ci E46 | from approx. 2002 | 3.0 l with supercharger, 297 bhp |
Records instead of races
We found nodocumented racing entries by AC Schnitzer Aachen with a verifiable result. The German Wikipedia mentions general entries in DTM and rally racing around 1987, without year, driver or result. What the brand is demonstrably known for, however, are top speed records with road-legal cars:
| Year | Vehicle | Record |
|---|---|---|
| 2003 | V8 TOPSTER (Z4), 450 PS | 305 km/h |
| 2005 | TENSION (M6 E63), V10, 552 PS | 331.78 km/h at Nardò — fastest road-legal BMW |
| 2007 | GP3.10 GAS POWERED, V10 on LPG | 318.1 km/h — record for LPG vehicles |
| 2009 | ACS3 3.5d Coupé | 288.7 km/h — record diesel car |
| 2016/17 | ACL2 (M235i), 570 PS | Nürburgring Nordschleife 7:25.80 min |
This is not a small track record. It is simply a different one than the one the brand is often credited with because of its name.
What the market pays
The price history of car No. 7 is one of the few cases in which a single car can be traced continuously over six years:
| Date | Event | Price |
|---|---|---|
| February 2019 | Offered in Hong Kong (Top Gear report) | approx. £120,000 |
| March 2021 | Offered via Contempo Concept, approx. 48,300 km | €126,648 |
| 19.12.2025 | Sold at Bring a Trailer | £147,993 (around US $185,000) |
For context: the average price of an E36 M3 on classic.com is around US $29,500, with the strongest factory benchmark of the model line — the M3 GT — around $174,000. The ACS3 CLS was above that. A tuner vehicle exceeding the most expensive factory E36 is the exception in this model line, not the rule.
This is market observation, not investment advice. A single, world-famous vehicle is not suitable as a benchmark for an E36 with catalogue parts.
March 2026: The end
On 20 March 2026, managing director Rainer Vogel announced that AC Schnitzer would cease business operations; remaining stock will be sold off by the end of 2026. He cites rising development and manufacturing costs, tariffs, supply chains, the weak global economy, the shift away from combustion engines — and approval procedures as reasons. His comment on this:
“If we can only bring add-on parts to market eight or nine months after the competition, that speaks for itself.”
Rainer Vogel, managing director, March 2026
Spare parts supply and warranty will continue beyond the end of the year, supported by the Kohl Group. Discussions about a sale of the brand were ongoing in March 2026; no names were given. We found no report of a deal by the editorial deadline of this piece — which does not mean there isn’t one.
The timeframe itself is disputed: the English Wikipedia states “by 2027”, while all German-language primary reports name the end of 2026.
How to tell the three apart
- ALPINA — independent vehicle manufacturer, own chassis number, complete vehicles from Buchloe.
- Hartge — recognised manufacturer since 1985, chassis numbers with W09, engine transplants from Beckingen.
- AC Schnitzer — parts and conversion programme, BMW chassis number, authenticity depends on the plaque, substance and invoices.
How ALPINA operated during the same period is covered in the piece on ALPINA from Buchloe. What the market pays in 2026 for classic BMW and what value demonstrably depends on is covered in the piece on preserving the value of classic BMW .
