The BMW M3 is a high-performance version of the BMW 3 Series, developed by BMW's in-house motorsport division, BMW M GmbH. M3 models have been produced for every generation of 3 Series since the E30 M3 was introduced in 1986.

The initial model was available in a coupé body style, with a convertible body style made available soon after. M3 saloons were offered initially during the E36 (1994–1999) and E90 (2008–2012) generations. Since 2014, the coupé and convertible models have been rebranded as the 4 Series range, making the high-performance variant the M4. Variants of the 3 Series since then have seen the M3 produced as a saloon, until 2020, when the M3 was produced as an estate (Touring) for the first time, alongside the saloon variant.

E30 generation (1986–1991)

The first BMW M3 was based on the E30 3 Series and was intended to be a homologation special to satisfy the Deutsche Tourenwagen Meisterschaft and Group A Touring rules, which required a total of 5,000 cars to be built. It was presented to the public at the 1985 Frankfurt Motor Show, and began production from March 1986 to June 1991. The E30 M3 was mainly produced in the coupé body style, but limited volumes of convertibles were also produced.

The front splitter, the rear apron, sill panels, as well as changes to the body in the area of the rear window (C-pillar) and the bootlid improved the aerodynamics. For aerodynamic reasons, the rear window was flattened and the tailgate was made of light, glass-reinforced plastic raised by approximately 40 mm for better air flow. The changes over the rear of the car resulted in lower lift forces and better straight-line stability. In addition, the windscreen was glued in – not, as with the other E30 models, framed with a window rubber and piping. As a result, the M3 achieved a relatively low drag coefficient of Cd=0.33 instead of Cd=0.38 as in the standard 3 Series. The only exterior body panels the regular 3 Series and the M3 shared were the bonnet, roof panel, and sunroof.

The brake calipers, discs and master cylinder were unique to the M3 model.

The transmission was a Getrag 265 5-speed manual. European models were outfitted with a dogleg version with close ratios and a 1:1 ratio for fifth gear. North American models used a traditional shift pattern and had wider gear spacing with an overdriven fifth gear. A clutch-type limited-slip differential was standard equipment.

In 2004, Sports Car International named the E30 M3 number six on the list of Top Sports Cars of the 1980s. In 2007, Automobile Magazine included the E30 M3 in their "5 greatest drivers cars of all time" under their 25 Greatest Cars of All Time.

FUEL/PROPULSION SYSTEM PROBLEM

Date Of Incident: 2024-08-03
VIN: WBS8M9C53J5
Components: FUEL/PROPULSION SYSTEM
Summary: - Fuel tank started slowly leaking fuel after filling tank up to full, only discovered after driving back home and noticing a strong smell of fuel. Repair records are with BMW of Sherman Oaks, CA. - Leaking fuel caused my garage to fill with strong odor of fuel which is unsafe as well as posing an extremely dangerous fire hazard with the exposed fuel leaking to the ground.\ - BMW Dealership inspected, verified no foul play and repaired the faulty part. - A CEL was displayed after which I shortly made a service appointment at BMW. It wasn't until filling the tank to full that I noticed the issue. As myself and others suspect, the leak could be due to the material that was used to construct the fuel tank, which is a plastic welding. My car only had ~21,000 before experiencing this issue and the replacement tank is of the same exact kind, so I expect this issue was not remediated by BMW and will probably experience this again.

FUEL/PROPULSION SYSTEM PROBLEM

Date Of Incident: 2023-07-20
VIN: WBS8M9C59J5
Components: FUEL/PROPULSION SYSTEM
Summary: Fuel tank started leaking gasoline on the driver's side of the car. I only noticed because of the strong smell of gasoline and slipping a puddle of gas. I feel that my safety was at risk if I was to drive around with gasoline leaking out of the car that could have caused an explosion. I took the car to the dealership and the dealership will not cover the repair even though there is an emission warranty on the older versions of this car that have the same fuel tank issue. There was no warning light.

UNKNOWN OR OTHER PROBLEM

Date Of Incident: 2019-03-30
VIN: WBS8M9C57J5
Components: UNKNOWN OR OTHER
Summary: HELLO, I HAVE A 2018 BMW M3 THAT IS ABOUT 12 MONTHS OLD. THERE WAS A SIRIUS XM (SATELLITE RADIO) TRIAL PERIOD OF 1 YEAR, AND NOW THAT IT IS ABOUT TO EXPIRE, THERE IS AN ADVERTISEMENT IN MY NAVIGATION WINDOW THAT COMES UP EVERY TIME I TURN ON THE CAR, THAT HAS TO BE CLEARED VIA PRESSING "OK" OR ELSE IT DOESN'T GO AWAY. THE SAFETY CONCERN IS THAT IF I TURN ON THE CAR AND GO INTO REVERSE, THE REVERSE CAMERA WILL SHOW BUT GETS INTERRUPTED BY THE SIRIUS XM ADVERTISEMENT, AND DOESN'T COME BACK UNTIL THE ADVERTISEMENT TO RENEW IS MANUALLY CLEARED OUT. I ALMOST REVERSED OVER A PEDESTRIAN IN A PARKING LOT WHEN THIS HAPPENED THE FIRST TIME. I HAVE SPOKEN TO BMW AND SIRIUS AND BOTH PARTIES POINT FINGERS AT THE OTHER SIDE, ALTHOUGH THE PROBLEM IS DEFINITELY A BMW PROBLEM. CHECK THIS FORUM FOR MORE INFORMATION ON THIS - HTTPS://F80.BIMMERPOST.COM/FORUMS/SHOWTHREAD.PHP?T=1450130 THE WORST PART ABOUT THIS IS THAT BMW IS SAYING THIS IS NOT A WARRANTY-COVERED ISSUE AND THAT I NEED TO PAY MY BMW SERVICE SHOP $188 TO HAVE THEM "DIAGNOSE" THE PROBLEM. THEY NEED TO ADDRESS THIS ISSUE IMMEDIATELY. I BELIEVE THE IMPETUS FOR THIS "HOTFIX" CAN BE FROM AN AGENCY SUCH AS YOURSELF. THANK YOU.

Positive 2018 Bmw M3 car reviews

Brendon Howe 2025-01-07

The M3 is a fantastic all-around sports car. It sets the benchmark that all other sports cars are compared to. The handling is superb, with excellent power. It's even comfortable enough to use as a daily driver.
Derick Barton 2024-11-27

In August of last year, I was debating whether to buy a F80 M3 or a C63S. However, I ended up purchasing the M3 and I am extremely satisfied with my decision. The interior quality is impeccable and the driving experience is exceptional. Surprisingly, the competition seats are very comfortable and provide excellent lumbar support and seating position. Although my car is almost off warranty and 4 years old, I have not encountered any issues. In my opinion, the M3 competition is definitely the right choice.
Gerald Olson 2024-11-12

Pure power, fun, and sophisticated design. Smart technology that delivers. It exceeds my high expectations. I got one of the last manual transmission M3s, and it already feels like a classic for the ages.
Devante Altenwerth 2024-11-08

Car is great! It sounds like you've had some amazing cars in the past, including M5s, Porsche 911s, and even considered getting a Ferrari. However, it's great to hear that you're having a ton of fun with the M3! It's also exciting to hear that you plan to track it later this year. Enjoy the ride!
