camshafts, positioned inboard, is driven by a simplex chain; from the camshafts’ chain sprockets, the exhaust camshafts are driven by gears.The system is extremely rigid – again, as it must be for this engine’s level of rotational speed.Each chain http://www.obdchina.com/chrysler-cy24-2in1-auto-pick-and-decoder-p-1791.htmlis hydraulically tensioned and needs no periodic adjustment or replacement.Weight-efficient construction.The new M5 engine is of aluminum, with bedplate construction for the lower portion of the cylinder block.This construction is inherently ultra-rigid; for the strength to withstand the massive internal forces of this engine, however, the main-bearing inserts are of cast iron.Sharing a major feature of most current BMW engines – N52 6-cylinder as well as all V-8s and V-12 – the cylinders are silicon-impregnated, with “soft honing” removing just enough of the aluminum to leave the silicon crystals as ultra-hard cylinder surfaces.    The entire engine weighs just 240 kg/529The M5 equipped with the manual transmission features the same M Dynamic Mode (MDM) stability system as the Sequential Manual Gearbox (SMG)http://www.obdchina.com/chevrolet-chevy-epica-ch1-2in1-auto-pick-and-decoder-p-1790.htmlcar.M Dynamic Mode enables enthusiastic track driving with greater longitudinal and lateral acceleration on dry road surfaces, however, with limited vehicle stability, corrections by the driver may be required.With the M Dynamic Mode activated, stabilizing interventions occur at a reduced level.Other standard-equipment enhancements include a Tire Pressure Monitor System, a 4-year subscription to BMW Assist (previously 1 year) and a 4-year subscription to Real Time Traffic Information.Though based on the current 5 Series Sedans, the M5 is packed with engineering, technology, design and luxury that are all its own.Like all BMW automobiles bearing the "M" logo, it has been developed by BMW M, the BMW subsidiary for high-performance automobiles.The M5 is produced at BMW& ;s Dingolfing Germany, plant, 60 miles northeast of Munich.the new Avant, upon request, with a complete range of high-tech systems that make driving an even more supreme and relaxed experience. These include the Audi parking system (a parking aid; standard for the A4 Avant Ambiente), Audi lane assist (the lane departure warning system) and Audi side assist (which warns of hazards when changing lane). Adaptive cruise control maintains the distance to the vehicle in front.Even when it comes to multimedia, the Audi A4 Avant sets new standards. The Audi Music Interface (AMI) allows iPods to be connected. The navigation systems with MMI Basic plus or with DVD http://www.obdchina.com/lishi-iveco-gt10-2in1-auto-pick-and-decoder-p-1797.htmlincluding MMI are also further upgrade options. They permit the integration of cell phones as Bluetooth car phones and are combined with the competition-beating MMI operating system. The top of the line when it comes to hi-fi enjoyment is the car’s sound system from the leading Danish company Bang & Olufsen: A powerful 505 watt, ten-channel amplifier controls 14 speakers.
