Running gear New high-performance running gear with single-wheel suspension Completely redesigned running gear with two dual-wishbone axlesTouareg V10 TDI with CDC air suspension The Touareg possesses a completely redeveloped high-performance running gear with single-wheel suspension. This intricately designed system forms the basis for the excellent street and off-road handling. The front boasts a dual-wishbone axle with upper aluminium links and lower steel links. The back of the Touareg also has a dual-wishbone axle, with forged aluminium links at the top and steel wishbones below. While the Touareg V6 uses steel suspension, Volkswagen equips the standard Touareg V10 TDI with CDC (Continuous Damping Control) air suspension. The CDC air suspension in detail The air-suspension system, like the system used in the Phaeton, guarantees an extremely high degree of comfort and ?????????????????????????????????????? with speed-dependent, automatic running gear lowering ?????????????????????????????????????? the dynamic characteristics of a very sporty car when driving on paved roads. Thanks to the variable running gear height, it also improves the off-road handling while continuing to provide a high level of comfort. The CDC air suspension always maintains the Touareg at a constant driving height. Four height sensors continuously measure the space between axle and body to keep the level between the front and rear axles even. As soon as the level deviates from the set position, the air volume of the suspension in the spring-absorber units is corrected by means of solenoid valves, a compressor and two accumulators. The Touareg??????????????????????????????????????s four air-spring absorbers essentially consist of air-spring bellows, a roller piston and the regulated hydraulic absorber. The electronic damping control (CDC) in detail An extensive sensor system detects the body and wheel acceleration; the control system itself reacts to the slightest unevenness in the ground and compensates for it by adjusting the shock absorbers. The damping system adapts to the vehicle??????????????????????????????????????s speed and current driving conditions, simultaneously minimising the tendency to roll or pitch. This positive effect also influences extreme acceleration or braking, for example, by reducing the body??????????????????????????????????????s otherwise normal structural movements. Running-gear switches grouped together in a control panel on the gearshift casing perform the basic adjustment of the air-spring and damping control. On the left is a rotary switch for the four-wheel drive, and on the right a similar switch for the air suspension. In between the two is a knob for adjusting the damping. Together these controls enable the manual adjustment of four different height levels and three different damping settings. In ???????????????????????????????????Auto Niveau???????????????????????????????? mode, which is primarily used on paved roads, the Touareg raises and lowers itself automatically based on vehicle speed. To optimise vehicle handling, the running gear sinks from 215 mm to 190 mm at 125 km/h. At 180 km/h, a height of 180 mm is automatically set. But the driver still has the option of setting other levels manually. Engines Ten-cylinder TDI provides the performance of a sports car The Touareg hits the market with six and ten cylinders
The V10 TDI achieves 313 hp and generates 750 Nm torque The Touareg??????????????????????????????????????s introduction to the market is starting with a 3.2-litre V6 petrol engine and a 5-litre V10 TDI. The V6 engine achieves 162 kW / 220 hp and develops up to 305 Nm torque. Compared to the technically related 3.2-litre engine of the Phaeton and Golf R32, the Touareg??????????????????????????????????????s six-cylinder was specially designed to be used in an off-road vehicle. Its adjustments include a modified oil pump with altered intake, an adapted sump for longitudinal and lateral inclinations, and a revised belt drive for improved fordability. The Touareg V6 reaches a top speed of 201 km/h (206 km/h with air suspension) and fulfils the EU 4 standard. In the U.S. it is classified Low Emission Vehicle (LEV). One of the world??????????????????????????????????????s most fascinating diesel engines is available with the completely new V10 TDI, which achieves 230 kW / 313 hp. Two additional engines will follow: a 2.5-litre, 5-cylinder TDI and a 4.2-litre V8 petrol engine. All models come with a six-speed gearbox ?????????????????????????????????????? manual or automatic depending on the engine ?????????????????????????????????????? for transmitting power to the 4XMOTION four-wheel drive. With the automatic gearboxes, the driver can influence gear changes via DSP (Dynamic Shift Programme), the Tiptronic gearshift, or, depending on the model, the shift rocker buttons on the steering wheel. V10 TDI ??????????????????????????????????????? Five-litre displacement, biturbo charging, pump-jet injection The completely new V10 TDI is one of the Touareg??????????????????????????????????????s most noteworthy technical highlights. With its enormous generation of power ?????????????????????????????????????? up to 750 Nm torque at just 2000 rpm ?????????????????????????????????????? it can master even the most difficult off-road terrain. And the Volkswagen with this engine also offers sports-car handling and performance with comparatively low fuel consumption. The Touareg V10 TDI accelerates from 0 to 100 km/h in just 7.8 seconds, reaches a top speed of 225 km/h, but uses only an average of 12.2 litres of diesel for 100 kilometres. In addition to the large displacement, the advanced pump-jet high-pressure direct injection (up to 2050 bar) and charging using a biturbo system with electrical charging-paddle adjustment play significant roles in this extraordinary power and performance development. Here is some information about the technological benchmark values for the V10 TDI, which is compressed in a 18.5:1 ratio: The cylinder spacing of the TDI is 88 mm, the bore 81.0 mm and the stroke 95.5 mm. The two five-cylinder banks are positioned at a 90???????????????????? angle to each other, permitting a flat design. The length of 544 millimetres is just as compact. An important requirement for the compact length of the engine is the control and auxiliary assemblies drive which, for the first time, has been constructed on one level in an aluminium wheel cassette which is acoustically decoupled from the crankcase. In addition to the extraordinarily high torque and performance characteristics and the compact dimension, exemplary quiet running was one of the most important development goals. One of Volkswagen??????????????????????????????????????s solutions for achieving it is to use a balancer shaft rotating counter to the crankshaft in the already low-vibration engine, depending on model. This balancer shaft eliminates the residual, free first-degree moments of inertia. Its effect is supported by six counterweights, manufactured from a tungsten alloy, which are fastened to the crankshaft. In terms of vibration, the V10 TDI thus runs at the level of a twelve-cylinder petrol engine. In addition, the engine is characterised by a uniform ignition interval of 72???????????????????? due to a split pin displacement of 18???????????????????? on the crankshaft; this results in a favourable vibration behaviour, even under load. The basic construction of the cylinder head is based on the pump-jet engines that Volkswagen has used in the past. However, for use in the Touareg??????????????????????????????????????s V10 TDI, the already newly designed head was again redesigned as a crossflow model, enabling the inlet side within the V to be realised in between the two cylinder rows. Direct injection itself takes on a key role: It optimises the mean pressures, the specific performance and the exhaust gas quality. The new pump jet used in the ten-cylinder engine is thus characterised by improved efficiency, a more compact solenoid valve and a significantly increased partial-load injection pressure. A completely redeveloped engine electronic system with two powerful control units enables precise modulation of the pump-jet injection elements, adapting the engine behaviour to the transmission of power. Advances that lead directly to an improvement in the handling and emission quality. The innovative design of the exhaust-gas system, with its two chrome-plated tailpipes, is an essential element of the exhaust-gas cleaning system. The engine is also equipped with pneumatically controlled exhaust-recirculation valves for reducing emissions. Furthermore, oxidation catalytic converters close to the engine help optimise the raw emissions, which are already low in general. The Touareg V10 TDI fulfils the EU 3 exhaust gas standard.
