Spy Shots: 2010 BMW 5-series sedan




When you think of luxury executive saloons, one car always comes to mind – the BMW 5-series. A class leader since its inception, the 5-series remains a crucial car in BMW’s lineup so there’s a great deal of importance surrounding the next-generation model. That car is due to arrive by late 2009 for the 2010 model year and heavily disguised prototypes have already been seen testing around the streets of Munich. These latest spy shots give us a better indication about what we can expect for the new executive saloon.

Most of the planned changes are skin-deep. Under the new sheet metal, BMW will continue with its new found love of turbocharging. The new 4.4L twin-turbo V8 from the recently revealed X6 is expected to appear in a range topping model, while more turbo-diesel variants are expected to join the lineup as well. BMW is currently developing its second generation common rail system for its diesel powerplants, which operate at greater pressure for improved performance. The transmission systems will include a six-speed manual and a six-speed Steptronic semi-auto gearbox, however a new eight-speed unit from ZF is also expected to be available. Coming in towards the end of 2010 will be the next-generation M5 sporting a larger displacement 5.5L V10 and possibly forced induction for extra power.
Performance will also be improved thanks to the extensive use of lightweight materials including carbon-fiber and aluminum. The car’s construction will be a hybrid of an aluminum spaceframe for the front section, and a traditional steel monocoque for the passenger compartment and rear. This will ensure a favorable front-to-rear weight distribution and improved handling. Up front will be an independent suspension with MacPherson struts, with a multi-link layout for the rear. High-performance models will include carbon-fiber body panels to shed even more weight.
Inside, the car will have a more spacious interior, especially for rear-seat passengers, while the center console will be oriented more towards the driver and run an updated version of iDrive. Headroom will be similar to the current model, despite a shorter roof for the new car, while trunk volume will grow to 550L. Wheel sizes will range from 17, 18 and 19in, and a new electrohydraulic brake system will also be added, which will improve braking distances and stability.
