The BMW 1 Series range is also the perfect showcase for BMW's EfficientDynamics technology and the new convertible continues that theme. Blending BMW's renowned driving dynamics and performance with class-leading economy and emissions, the BMW 1 Series Convertible delivers driver enjoyment and low running costs in equal measure.
The range is initially available as BMW 120i and 125i Convertible models, but will be joined a few weeks later by three other engine derivatives, the 118i, 120d and 135i. Two Hams Hall derived four-cylinder powerplants (118i and 120i) offer an affordable way into BMW 1 Series Convertible ownership, while the 120d four-cylinder diesel engine is the most economical in the range. Two six-cylinder engines, powering the 125i and 135i, balance performance and refinement to offer the best in open-air driving dynamics. The 218hp engine in the 125i Convertible is a first for the 1 Series model range. The 306hp engine in the 135i is the current International Engine of the Year holder and powers the range flagship.
BMW's smallest four-seat convertible might be compact in dimensions, but it features the same technology as some of the marque's larger luxury models. One such key feature of the 1 Series Convertible is that all leather-upholstered cars come as standard with BMW's innovative SunReflective leather technology. This helps keep the surface temperature of the upholstery on a hot day up to 20 degrees centigrade lower than a normally upholstered leather seat. The BMW 1 Series is also ahead of the competition as, unlike some competitors, it has a completely electric-powered roof that can be raised or lowered at speeds in excess of 30mph.
