The three-door version BMW 1-Series development is evidently continuing after our spies caught this prototype out testing in winter conditions. Nearly all camouflage has now been removed which has revealed some of the finer details of the hatchback.

Although we have seen most of this in the past, the styling will mirror the already revealed five-door version and design patents have also surfaced of the three-door model variant.

The new 1-series rides on a rear-wheel drive platform and offers an updated range of turbocharged engines. The 116i and the 118i are powered by a 1.6 liter turbo engine that has been tuned to respective power outputs of 134 bhp (100 kW/136 PS) and 168 bhp (125 kW/170 PS). There will also be three diesel units on offer with outputs of 114 bhp (85 kW/116 PS), 141 bhp (105 kW/143 PS) and 182 bhp (135 kW/184 PS).

The three-door BMW 1-series is expected to hit the first dealerships in the summer.
