These are the latest pictures of the next-generation BMW 1-series in testing.
The model spied here is the five-door 1-series, which is tipped to be launched in 2011.
As with today’s 1-series, the 2011 model, codenamed F20, features a modular platform with BMW’s traditional longitudinal engine layout, aspects of which are set to be shared with the next-gen 3-series.
Together with standard rear-wheel drive - a feature that will continue to set the 1-series apart from all of its hatchback rivals - BMW is also considering adding four-wheel drive by using the system developed for the X1.
The biggest news is the new turbocharged three-cylinder engine that will be fitted to entry-level models. It forms an integral part of BMW’s future Efficient Dynamics programme.
Sources inside BMW’s R&D centre suggests the new engine delivers between 110bhp and 160bhp, depending on its state of tune. As a 110bhp unit it should be capable of delivering combined fuel consumption of over 70mpg and CO2 emissions of under 100g/km.
