What is the engine code for the BMW M3's V8?
2 Answers
The engine code for the BMW M3's V8 is S65B40. This engine was transplanted from the BMW M5 and is the first V8 engine in the history of the BMW M3. The S65B40 engine incorporates F1 racing engine technology and features BMW's Double VANOS and Valvetronic technologies. The BMW M3's design continues BMW's signature sharp lines and muscular appearance, fully showcasing the personalized style of the BMW 3 Series. The elongated hood, dynamic long wheelbase, noticeably rear-set cabin, and short front overhang clearly demonstrate the BMW 3 Series Coupe's more sporty inclination compared to the standard 3 Series.
I remember the V8 engine in the BMW M3 was codenamed S65, serving as the powerhouse for the E90 and E92 generation M3 with a 4.0-liter displacement and an impressive output of 414 horsepower. As a car enthusiast, I adore its high-revving character—it can scream up to 8,400 rpm, sounding like pure music. BMW opted for a V8 over the traditional inline-six to enhance performance responsiveness, and it delivered stunning results on the track. If you've driven this generation M3, you'd feel its linear acceleration and exhilarating push-back sensation. Sadly, BMW later returned to the inline-six, making this V8 a true classic. Maintenance-wise, the oil pump in this engine can be a bit fragile, so regular oil checks are recommended to avoid overheating issues. Overall, it represents the golden era of the BMW M series—I still find myself glancing at older M3s on the street, reminiscing about that pure driving joy.
