Only three exist. BMW owns all of them. And one just made a quiet trip to Paris.
The M3 GTR Strassenversion — the most extreme road-legal E46 ever produced — emerged from BMW’s private collection for a special exhibit at the Grand Palais, marking 40 years since the original M3 went on sale in 1986. It sat under glass alongside an E30 M3, an E36 M3 GT, and a current G80 M3 Competition xDrive. Four decades of the nameplate, distilled into four cars, but only one of them made people stop breathing.
BMW built 10 M3 GTRs for the street. Then it crushed seven of them. The prototypes were destroyed, and the three surviving production-ready examples never left company hands. No collector has ever owned one. No auction house has ever listed one. At its 2001 debut, the sticker read €250,000 — and nobody got the chance to pay it.
The car’s engine tells the whole story. The P60B40 was a naturally aspirated 4.0-liter flat-plane-crank V8 pulled directly from BMW’s ALMS race program. In street trim it made 346 horsepower and 269 pound-feet of torque, numbers that sound modest today but meant something very different bolted into a car weighing just 2,976 pounds.
BMW gutted the rear seats, ditched the air conditioning, ripped out the radio, and layered in carbon fiber wherever it could shave grams. The result was roughly 77 pounds lighter than the already lean CSL. And unlike the CSL, which came saddled with BMW’s polarizing SMG automated manual, the GTR Strassenversion got a proper six-speed stick.
The Paris appearance was part of BMW’s partnership with Tour Auto, now in its 35th edition. It was a calculated flex — a reminder that before BMW pivoted to turbos, then hybrids, then full electrics, it once dropped a race engine into a 3 Series and called it a production car. The kind of homologation special that existed because regulations demanded it and engineers seized the opportunity.
That era is gone. Modern emissions standards have locked the door on race-derived powertrains in street cars. Naturally aspirated engines are vanishing from BMW’s lineup entirely.
A V8 in an M3 will almost certainly never happen again — the S65-powered E9x generation was the last to carry eight cylinders, and clean examples now command staggering money. A 725-mile E92 M3 recently sold for over $200,000 on Bring a Trailer.
BMW has already confirmed the next-generation M3 will arrive in two forms: a fully electric version, the M3 ZA0, expected around 2027, followed by a combustion-powered G84 with an inline-six roughly a year later. The straight-six lives on. The flat-plane V8 does not.
Which is precisely why pulling the GTR Strassenversion out of cold storage matters more than any press conference about the future. BMW knows what it has. Three cars, locked away, appreciating in legend if not on any balance sheet.
Showing one in Paris wasn’t nostalgia. It was a reminder of what the company was capable of when the rulebook left room for madness — and a tacit acknowledgment that the window closed permanently behind it.
