The 2001 BMW 330xi is part of the E46 generation, known for its blend of sporty handling and luxury features. The 330xi specifically features all-wheel drive, making it a popular choice for those in climates with challenging weather. The primary engine available in the 2001 330xi is the 3.0-liter M54 inline-six, producing 225 horsepower and 214 lb-ft of torque. While the E46 is appreciated for its driving dynamics and classic BMW styling, some common complaints include electrical gremlins, cooling system issues, and suspension wear. Some owners also find the maintenance costs associated with BMW ownership to be higher than average. Transmission options are a 5-speed manual or a 5-speed automatic.
