The BMW 3 Series E90/E91/E92/E93, produced from 2005 to 2012, represents the fifth generation of the iconic 3 Series, a renowned nameplate known for its balance of performance, handling, and luxury. The E90 designation refers to the sedan body style, while E91 denotes the touring wagon, E92 the coupe, and E93 the convertible. This generation saw significant improvements over its predecessor, the E46, with a new platform, updated styling, advanced technology, and a wider array of powertrain options. The E90's design, penned by Chris Bangle, featured a more angular and bold aesthetic, departing from the smooth curves of the E46. The interior received a significant overhaul, gaining a more modern and driver-focused layout with improved ergonomics and materials.

Under the hood, the E90/E91/E92/E93 offered a diverse range of gasoline and diesel engines, including the iconic 335i with its twin-turbocharged inline-six engine. The 335i's potent performance, combined with the E90's refined handling and balanced chassis, cemented its reputation as a true driver's car. The E90 platform also saw the introduction of BMW's EfficientDynamics technology, which focused on fuel efficiency and reduced emissions. This generation also offered a range of advanced features, including BMW's iDrive infotainment system, adaptive headlights, and a head-up display. While the E90 generation faced criticism for its initial styling, its overall impact on the 3 Series' legacy remains significant. It further solidified the model's position as a benchmark for luxury sports sedans, offering a compelling blend of performance, technology, and refinement.
