The BMW 1-Series, a compact executive car produced by BMW from 2004 to 2019, marked a significant departure for the German automaker. The first-generation 1-Series, encompassing the E81/E87 (sedan) and E82/E88 (coupe/convertible) models, introduced the world to a rear-wheel drive platform in a compact car segment dominated by front-wheel drive competitors. This pioneering move allowed BMW to retain its hallmark driving dynamics, offering a level of handling and agility unmatched by its rivals. The 1-Series, while smaller than the 3-Series, remained true to the BMW ethos, boasting a driver-focused cockpit, precise steering, and a sporty character, making it a favorite among enthusiasts seeking a more affordable entry point to the BMW experience.

The 1-Series E81/E82/E87/E88 models were offered with a diverse range of petrol and diesel engines, catering to a broad spectrum of driver needs. From the economical 116i and 118d to the performance-oriented 135i and 123d, the 1-Series offered a compelling blend of power and efficiency. These models also introduced numerous innovations, including the first application of BMW's EfficientDynamics technology and the pioneering use of a six-speed dual-clutch transmission. The 1-Series E81/E82/E87/E88 models quickly gained popularity as a stylish, dynamic, and practical compact car, establishing itself as a worthy successor to the much-loved 3-Series Compact. With its distinctive design, engaging performance, and hallmark BMW quality, the 1-Series E81/E82/E87/E88 continues to be a sought-after and appreciated model among car enthusiasts.
