Detailed Explanations
E30 (1986-1991)
The E30 M3 is the genesis of the legend. Born from Group A Touring Car racing homologation requirements, it boasts a high-revving four-cylinder engine (S14) and a lightweight chassis. Its box flares and aggressive stance are instantly recognizable. The E30 M3 offers a pure, unfiltered driving experience unlike any other. Expect to pay a premium for a well-maintained example, as they are highly collectible.
E36 (1992-1999)
The E36 M3 marked a significant shift, moving from a four-cylinder to a larger inline-six engine. It's a more refined and comfortable car than the E30, but still offers impressive performance. US-spec E36 M3s (S50 and S52 engines) have less power than their European counterparts (S50B30 and S50B32 engines). While generally reliable, E36s are getting older, so thorough inspections for rust, worn suspension components, and cooling system issues are essential. This generation can represent a good value entry point into M3 ownership.
E46 (2000-2006)
The E46 M3 is widely regarded as one of the best M3s ever made. Its S54 inline-six engine is a masterpiece, delivering exhilarating power and a signature exhaust note. The E46 chassis offers exceptional balance and handling. However, the E46 M3 is known for a potential subframe cracking issue. Reinforcing the subframe is a crucial preventative measure to avoid costly repairs. Other common issues include VANOS (variable valve timing) problems and cooling system failures.
E90/E92/E93 (2007-2013)
The E90 (sedan), E92 (coupe), and E93 (convertible) M3s are the only M3s to feature a V8 engine. The S65 V8 is a high-revving, naturally aspirated beast that provides a unique and visceral driving experience. However, the E9x M3 is notorious for rod bearing issues. Replacing the rod bearings with updated ones is highly recommended, especially on higher mileage examples. Other potential issues include throttle actuators and valve cover gasket leaks. Despite these potential problems, the E9x M3 offers a thrilling driving experience and a distinctive sound.
F80 (2014-2018)
The F80 M3 marked the return to an inline-six engine, this time with turbocharging. The S55 engine delivers impressive power and torque, making the F80 M3 incredibly fast. It's also more efficient than the E9x M3. Some enthusiasts find the steering less communicative than previous generations, but the F80 M3 is still a capable and enjoyable performance car. Potential issues include charge pipes cracking and oil leaks.
G80 (2021-Present)
The G80 M3 is the latest generation, featuring a powerful turbocharged inline-six engine and advanced technology. It's the fastest and most technologically advanced M3 yet. However, its controversial styling has divided opinions. The G80 M3 is also available with all-wheel drive (xDrive) for the first time. It's still relatively new, so long-term reliability is yet to be fully determined. Early models have shown some software glitches and sensor issues.
