2010 BMW 5 Series in the making

There's lots of talk surrounding the 2010 model year 5 Series line-up as sedan and wagon prototypes have been spotted making their rounds along the streets of Munich.

Although most changes might just be skin-deep, some of the new 7-series' technical upgrades might be entirely possible, including the Dynamic Drive active anti-roll bars, four-wheel steering and active dampers that could play the part of a higher-end performance variant. BMW's night-vision, lane departure and active brake assist are also amongst the many possibilities.

BMW's new habit of forced-induction will continue with the 4.4L twin-turbocharged V8 that is expected to be lifted from the X6 in addition to the usual staple of turbo-diesels. BMW's next generation of common rail diesel engines will also be designed to operate at higher pressures so as to improve performance. Amongst these, a 204 hp 2.0-litre, twin-turbocharged four-cylinder diesel.

Gear-boxes expected to be bolted onto the car will be a six-speed manual, six-speed "Steptronic" semi-automatic and believe it or not, a new eight-speed unit from ZF.

Further down the road, the M5 will sport a larger displacement 5.5-litre V10, and possibly forced-induction. Do anticipate the addition of stop-start technology for reduced emissions in the more economical, less powerful variants.

BMW will continue their widespread usage of carbon-fiber and aluminium, eventually turning the car's body into an aluminium spaceframe for the front, and traditional steel monocoque for the passenger compartment and the back. This will continue BMW's promise of balanced front-rear weight distribution figures that will of course, improve the handling. An independent MacPherson strut front suspension and multi-linked rear layout will continue to be standard while a new electro-hydraulic brake system will also be added. BMW claims this will shorten braking distances and increase stability under hard braking.

In addition to a more spacious interior, the centre-console will once again be oriented more towards the driver, and run an updated iDrive module. Headroom will be similar to the current model despite a shorter roof. Boot capacity is expected to rise to 550 litres in volume.
