The prototype is disguised under a chopped-up five-door body from the current model, but reveals that BMW will provide the next 1-series with an extended wheelbase to improve interior space.
This 1-series test car has a modified B-pillar and doors, which have been extended front and rear with larger openings to rectify one of the 1-series' biggest weaknesses - the awkward entry to the rear. BMW has also extended the car's tracks to improve stability and handling.
BMW insiders have said that the suspension (MacPherson struts up front and multi-links at the rear) has also been revised, gaining slightly modified geometry and a greater number of aluminium components to sharpen responses and reduce weight.
The steering on the new BMW 1-series will adopt an electro-mechanical rack, as seen on the Z4. "With the growing concern over fuel economy and CO2 emissions, it brings a number of advantages while using less energy," said a source involved in the development of the new model.
BMW is planning a highly modular approach to the second-generation 1-series platform and suspension. The components have been designed to underpin a wide range of models, ranging from the X1 off-roader through to the next 3-series and an as-yet-unconfirmed MPV. Munich insiders said that the wheelbase and track widths on all models will vary quite dramatically.
Alongside standard rear-wheel drive, BMW is planning a four-wheel-drive version of the chassis, with its new torque-vectoring system.
Engine choices will include modified versions of the Mini's 1.4 and 1.6-litre four-cylinder, which have been conceived, developed and produced in partnership with Peugeot. They will join a new line-up of BMW engineered turbocharged four and six-cylinder petrol and diesel engines.
