The BMW 1-Series (E81, E82, E87, E88), produced from 2004 to 2013, marked a significant departure for BMW, introducing the first rear-wheel drive platform in the premium compact segment. Its compact size and agile handling made it an immediate hit amongst drivers seeking a blend of practicality and sporty performance. The E81 and E87 models were three-door and five-door hatchbacks respectively, while the E82 and E88 represented the coupe and convertible versions. All variants boasted a range of powerful petrol and diesel engine options, offering varying levels of performance and fuel efficiency. The 1-Series also pioneered a unique feature – the "Runflat" technology, enabling driving for a short distance even with a punctured tire, adding to its practicality and safety.

The 1-Series was lauded for its precise steering, responsive handling, and engaging driving experience. While the interior wasn't as luxurious as its larger siblings, it offered a well-designed and ergonomically sound cabin, prioritizing comfort and functionality. The 1-Series was also praised for its fuel efficiency, with diesel engines offering impressive economy figures. However, as the car was relatively compact, rear passenger space was limited, particularly in the coupe and convertible variants. The first generation 1-Series was a groundbreaking entry for BMW, offering a compelling driving experience and practicality in a compact package, attracting a younger and more dynamic audience. Despite its limitations, it cemented BMW's position as a leader in the premium compact segment, paving the way for the future generations of the 1-Series.
