NASA Spec E46

About This Class

Spec E46 is a growing NASA spec class using the 2001-2006 BMW 330i/330ci, providing a more modern and more powerful alternative to the established Spec E30. With approximately 225 hp from the M54 inline-six, the E46 offers higher speeds and more demanding driving dynamics while maintaining the spec-class philosophy of equal equipment and driver-focused competition. The class is rapidly gaining popularity as E30s become scarcer and pricier.
