Responsible for this - along with an intelligent electro-hydraulic transmission control (mechatronics) - are two clutches as well as two drive shafts and three final drive shafts. Mercedes-Benz will feature three world premieres, which will be showcased alongside the brand's two North American debuts, while Porsche will hold several world reveals. What’s up in the air at this point is what will arrive in Canada in the fourth quarter of 2012 (yes, a year from now!) - both power and engine size-wise. This relieves engine load, which in turn reduces fuel consumption. The most powerful 125 kW / 170 PS Tiguan TDI, which always comes with all-wheel drive, has a combined fuel consumption of 6.0 l/100 km (equivalent to 158 g/km CO2); this is also 0.3 litres less than on the previous model. This is done by an electrohydraulic all-wheel drive clutch. Clutch I handles the odd-numbered gears, and clutch II the even gears plus reverse gear. Different unique or luxurious interior items embrace a multifunction sports steering wheel with a flattened bottom section and a thick leather crown, plus accessible sun-reflecting leather that noticeably reduces seat temperature, furthermore ambient lighting. Even cobblestones were put down on a short section of the test track in Sindelfingen.
Matt went out of his way to make sure everything was perfect, and even though he was on lunch break when I came in, he interrupted his personal time to deliver my vehicle himself. The alternator may even be shut off entirely. The amount of transferred torque may be continuously varied by altering the magnitude of the pressure applied to the clutch plates. Here, the surface pressure on the clutch plates is proportional to the torque desired at the rear axle. The pressure reservoir is supplied with oil by an electric pump with a working pressure of 30 bar. An important difference compared to the previous generation 4MOTION: no speed differences are needed between the front and rear axles to activate the all-wheel drive clutch, since pressure is built up via an electric pump. Also expected to be in very high demand is the new Tiguan 2.0 TDI as a 140 PS version with all-wheel drive and BlueMotion Technology: with a manual gearbox, it consumes a low 5.8 l/100 km and with a DSG transmission 6.0 l/100 km. Normally, the front axle is driven in the 4MOTION system - including on the all-wheel drive Volkswagen Tiguan; the rear axle only gets ten percent of propulsive power.
It produces its maximum power at 4,200 rpm. Between 1,750 and 2,500 rpm the engine develops a maximum torque of 350 Newton metres - enough power and force to accelerate the Volkswagen Tiguan to 100 km/h in 8.9 seconds with a top speed of 201 km/h. All versions of the 140 PS TDI are characterised by a very high maximum torque of 320 Newton metres between 1,750 and 2,500 rpm. An electronic control unit computes the ideal drive torque for the rear axle and regulates, via a valve, how much oil pressure is transferred to the working piston of the multi-plate clutch. If you are a little more rural and want more power beneath the bonnet, then an SUV may be a great alternative with just as much family friendly room - but not as many eco-credentials. You can only choose one filing status on your tax return, but your filing status may change from year to year.
The automaker says the flange connection between the exhaust gas turbocharger and the exit to the diesel particulate filter may not have been attached properly. Unlike vehicles without the Stop/Start system, the BlueMotion Technology models have an extra battery data module (for acquiring momentary battery charge status), a heavy-duty engine starter, a DC/DC converter (guarantees voltage stability in the vehicle's electrical system) and an exceptionally durable deep-cycle glass mat battery on board. This causes the engine to shut off momentarily. As soon as the traffic light turns green again, the driver depresses the clutch (or with DSG simply releases the brake), and the engine starts, the "Start (A) Stop" text is cleared, the driver engages a gear and resumes driving. In addition, the battery - always optimally charged - supplies the vehicle's electrical system with sufficient energy during the stopped phase of the engine (e.g. at traffic lights). The possible applications include embedded diagnostics, software updates or upgrades, off-board navigation and destination download, traffic information and mobile search. Battery regeneration requires special software for energy management and modified engine controller software. Thanks to this alternator control as a function of engine efficiency, and the optimally charged battery that results, the voltage of the alternator can be reduced whenever this is desirable - e.g. when accelerating or while constantly maintaining a desired speed.
A Mercedes-Benz 5 speed automatic transmission with cruise control is also available as an option. When the Tiguan is driven off from a standstill or accelerated, wheelspin of the front wheels is fully prevented, since the control unit regulates the torque distribution based on dynamic axle loads. The new SL has adopted the proven braking system with a dual-circuit brake and the split of the two braking circuits between the front and rear axle from the predecessor model. In extreme cases, nearly 100 percent of the drive torque can be directed to the rear axle. Not until necessary - based on the specific powertrain and carriageway situation - is the rear axle brought into play, step by step. The multi-plate clutch system itself was integrated in the rear differential. This includes blind-spot alerts, rear cross-traffic warning with automatic braking, surround-view cameras with reverse guide lines, intelligent cruise control, lane-keep assist, traffic-sign recognition, and a driver attention-monitoring system.
