Welcome to M3 Addict

M3 Addict is devoted to all things M3. I own a 2006 M3 and I absolutely love it. As a result - Driving my M3 has become my passion and I have set this site up to allow others to share in my passion. What a fantastic Machine! While I get more content up on the site, take a moment to read this fantastic press release from December 1, 2000 about the exciting launch of the new M3:

The New BMW M3: A Legend is reborn, December 1, 2000


December 30th, 2008:
BMW's Legendary S54B32 Engine Is Retired

BMW has retired its classic 3.2 liter inline six-cylinder engine. And when I say "classic" I mean probably the sweetest, most balanced, highest reving, most powerful naturally aspirated 3.2 liter engines we'll ever be graced with.

The powerplant, known as the S54B32 amongst BMW engineers and automotive purists, powered the last generation Z4 M Roadster and Coupe, the M3 (E46) and a several earlier generation Z3 M Roadster and Coupes too. The 3.2 liter engine distinguished itself as a naturally aspirated straight-six churning out 343 hp - more than 100 hp per liter without any artificial induction. That simplicity and artfulness of engineering made the engine renowned for its steady levels of torque across the rev band.

One should always be weary when an automaker phases-out a classic product and replaces it with the new and unproven. How many times has a manufacturer messed up the process of renewal and actually taken a product line a few steps back? After all, this engine won the International Engine of the Year award upon its introduction in 2001 as well as winning the 3.0 to 4.0 liter category for six consecutive years between 2001 and 2006.

But this is BMW and maybe a little trust is warranted. They don't usually leap blindly into the marketplace with under-developed products, especially engines.

The S54B32 will be replaced in the Z4 by other inline six-bangers, including a 2.5 liter, 201 hp and a twin-turbo 3.0 liter with 302 hp. Let's hope those powerplants come packed with the same kind of supple sizzle.

BMW Dominates Engine Of The Year Awards!

2008 BMW M3 4.0 Liter V8 S65 Engine






The "International Engine of the Year Award" is a big deal as far as bragging rights go in this industry. Think of it like the Academy Awards for engines. However, instead of members of the Academy of Motion Picture Arts and Sciences voting, you have 62 renowned motoring journalists, from 30 countries, casting ballots for their favorite fossil fuel burner.

BMW Motorsport Heritage

Only 453 were ever built, yet the designation alone still carries the power of legend. M1. The shape, the sheer power, and the passion embodied in every detail continues to inspire drivers, artists and aspiring designers to this day. The M1 was the precedent. The Benchmark. No longer would BMW's elite Motorsport division create cars only for the world of racing. Now, that immediacy, responsiveness and pure excitement would be available to true enthusiasts the world over.
