BMW 1-Series Convertible (2008-2015)

The E88 first generation BMW 1-Series Convertible marked a return to smaller BMW convertibles as the 3 and 4 Series gets ever larger. Unlike its bigger brother, it has a fabric folding roof which maximises the luggage space and gives the car attractive proportions. Quality, equipment and performance are as you would expect from BMW. The original two engine options for the launch model have increased to included a base model 118 and range-topping 135, while a diesel option, 120i and 125i joined later. The 135 promises M-Sport-like performance with a 0-62mph time of just 5.6 seconds.

BMW 1-Series 125i Convertible

BMW 1-Series 120d Convertible

Combining punchy performance with great economy, the BMW 120d Convertible is a great choice. The 2-litre turbo diesel engine is refined, with a good spread of power throughout the rev range. Enthusiastic drivers may also want to consider the more powerful 123d.

BMW 1-Series 123d Convertible

The twin-turbo 2 litre BMW 123d Convertible is the clever choice in the range. Combining serious performance with forgiving economy, it is hard to fault. It pulls well from low in the rev range and doesn't have the clattering soundtrack often associated this diesel engines. While it isn't a match in performance for the 135i it is a far more economical car to use every day.

    With its attractive exterior styling, spacious interior design, well-planned proportions, and decent performance stats, the new BMW 1-Series convertible is clearly one of the best choices for a luxury small convertible on the present market.

  2. Rat Rat says:

    Bought mine just 10 days ago and I’m in love…. the 3 litre is juicy but soo much fun – 35mpg is achievable but if that’s your concern then don’t buy that engine buy a diesel…#shudder…. sorry feels dirty just saying the word!

  3. Lorne Sinclair Lorne Sinclair says:

    Pure driving pleasure unless you live where there is snow. Put it in the garage in winter season and enjoy the rest of the year.
