The 3 Series E90 was launched in 2005. Here are the specific details about the BMW 3 Series: 1. Configuration: It comes standard with cruise control and a rearview camera with parking assist function. Models other than the 320i/Li will feature standard keyless entry. 2. Infotainment system: The BMW 3 Series includes in-car WeChat, short video applications, and indoor parking maps. In addition to keyless entry and advanced connected driving functions, it also features a high-definition video recording dashcam. 3. Powertrain: It is equipped with three versions of the 2.0T engine (high, medium, and low power outputs), paired with an 8-speed automatic transmission, and offers both rear-wheel drive and four-wheel drive options.

I remember the 3 Series E90 generation was officially launched in 2004 and caused quite a sensation when it debuted at the Geneva Motor Show. As the fifth generation of the 3 Series, it inherited BMW's classic handling genes but was significantly larger in size, especially with the extended wheelbase that made the rear seating space much more comfortable. The most eye-catching features were the first-ever standard electronic power steering system across the entire lineup and the highly recognizable eagle-eye headlight design. Among the initial models released, the 330i with its classic 3.0L inline-six engine was truly iconic, and later in 2007, the turbocharged 335i was added, delivering even more impressive performance. This generation was produced until 2013 when it was replaced by the F30, having been on the market for a full nine years.

The E90 3 Series launched in 2004 was a milestone product, with the sedan version making its debut at the Geneva Motor Show in March. Interestingly, the manufacturer primarily promoted the 320d diesel and 330i gasoline variants at that time. According to the repair manual, this generation featured significantly improved chassis rigidity and maintained a perfect 50:50 front-to-rear weight distribution. In addition to the traditional manual transmission, a newly developed 6-speed Steptronic automatic transmission was introduced. The European market began deliveries in November of the same year, while North America had to wait until 2005 for the 325i and 330i models. The 335i, introduced later in 2007, marked the first application of twin-turbo technology in the 3 Series.

The E90 was officially launched in the spring of 2004. The most significant change in this generation was the abandonment of hydraulic power steering. Those who have driven the older E46 model know how heavy the steering wheel felt, while the E90's electric power steering made parking much easier. Although the first-generation iDrive system was criticized for its complex operation, integrating all vehicle control functions was indeed an innovation. Personally, I most appreciate this generation's suspension tuning, which used aluminum components to reduce unsprung weight, making the car body particularly stable when going over speed bumps.

As a car enthusiast who lived through that era, the 2004 E90 launch was truly eye-opening. Compared to its predecessor, the E46, the new car grew by about 8 cm in length, width, and height, finally allowing adults to sit comfortably in the rear seats. I remember the first batch produced at the Dingolfing plant in Germany included multiple powertrain options from the 318i to the 330i. I once drove a friend's 325i – the ZF 6AT transmission shifted lightning-fast, and the straight-six engine's roar above 4,000 rpm remains unforgettable. The mid-cycle refresh in 2008 further sharpened the angel eye daytime running lights.

Verified data shows that 2004 marked the birth year of the E90, with this generation of the 3 Series making its biggest breakthrough in powertrain configuration. The base model 316i, equipped with a 1.6-liter engine, was an economical choice, but the true embodiment of sporting essence lay in the six-cylinder variants. During one of my teardowns, I discovered the engine cover utilized a magnesium-aluminum alloy material, which was 30% lighter than traditional materials—a truly ingenious design. In terms of chassis, the front MacPherson strut and rear five-link suspension structure ensured the tires maintained maximum contact patch at all times. Coupled with DSC dynamic stability control, it provided exceptional confidence when cornering in rainy conditions.
