The Bmw 5-series led its series since the beginning and still remains an essential part of the company's lineup, that's the reason why there's a heightened expectancy level for its next-generation version arriving late this year for the 2010 model year.
Fresh details which have filtered through show that much of the alterations intended for the car are cosmetic prior reports that said the 5-series will replace its body structure have been found incorrect as it will still come with the series' polarizing appearance along with some derivatives of the CS concept.
This seems to be a strange approach considering that the brand new 7-series have already distanced itself from that particularly controversial exterior to a more acceptable look. The new 5-series model could come with Dynamic Drive active anti-roll bars, 4-wheel steering and active dampers. Safety features could include a night-vision system, lane departure warning and active brake assist.
According to our sources, the engine will undoubtedly receive turbocharging as Bmw has developed a penchant for it lately. The anticipated powerplant for this new model will be the X6's 4.4-liter bi-turbo V8, with more turbo versions expected to join the lineup. Currently, BMW is working on a second-generation common rail system for its diesel engines that operate on higher pressure for enhanced performance.
Likely to be included for the European model, but not for the US, is the 204hp (152kW) 2.0 twin-turbo 4-cylinder diesel engine. Ultimately, BMW will produce hybrid versions. Available transmission systems consist of a 6-speed manual and a 6-speed Steptronic semi-automatic gearbox, and a new 8-speed unit from ZF can also be expected. At the end of 2010 the next-generation M5 will be available and will come with larger displacement 5.5 V10 and the likelihood of forced induction for added potency.
By 2011 stop-start technology for low emission and fuel economy will be added to less performance-geared versions. Improvement of performance for all models is achieved by utilizing lightweight materials like aluminum and carbon-fiber.
The vehicles construction will involve a combination of aluminum spaceframe for the front section and the regular steel monocoque for the rear and passenger area and it will utilize MacPherson independent suspension struts for the front and a multi-link layout for the rear suspension, thus providing an excellent front to rear weight distribution which in turn enhances handling.
To reduce more weight, high-performance models will come with carbon-fiber body panels. In the interior, the rear passengers will enjoy more space, while the center console will be more oriented to the driver and will come in an updated variant of the iDrive. Although it has a shorter roof, headroom will be the same as the present model, and the trunk will have a larger 550-liter volume. Braking system will be the latest electrohydraulic which enhances braking distances and stability, and wheels will come in 17, 18, and 19-inch configurations.
