Engines and Transmissions
- First SUV in the world exclusively with charged engines
- New Common Rail TDIs already satisfy Euro 5 emission standard today
- High torque TSIs are predestined for off-road use
The Tiguan will be the first SUV in the world to arrive on the market exclusively with charged TDI and TSI engines. The advantage: Greater power and torque, better fuel economy and lower emissions. In the starting phase, the new SUV will debut with a new 110 kW / 150 PS strong TSI and the first four cylinder commmon rail TDI of the Volkswagen brand; it outputs 103 kW / 140 PS.
Over the mid-term two other TSIs and a TDI will be offered. They are all new to the Volkswagen lineup. The TSI range will be extended by adding two four cylinder engines: 125 kW / 170 PS and 147 kW / 200 PS. Following up in the diesel area, there will be a powerful 125 kW / 170 PS TDI; it also sports newly developed common rail injection. The stated development goal here was to offer the quietest diesel engines of the class in the Tiguan. Both direct-injection turbo-diesel engines will already fulfill the Euro-5 that does not go into effect until 2009. The engines of the Tiguan in detail:
TSI with 110 kW / 150 PS
The new 110 kW TSI (with supercharger and turbocharger) accelerates the Tiguan to 100 km/h in 9.3 seconds. Its top speed is a respectable 192 km/h. Maximum engine torque: 240 Newton-meter, available from a low 1,750 rpm. Fuel consumption: 8.4 liters per 100 kilometers. Special feature: In combination with the Tiguan Track&Field, the supercharger on this TSI is always engaged in off-road mode, in order to be able to master even the most difficult off-road passages with high torque at low rpms and vehicle speeds.
TSI with 125 kW / 170 PS
In the mid-performance position, a newly developed TSI engine is being introduced with 125 kW / 170 PS. The two-liter directinjection turbocharged engine accelerates the Tiguan to 100 km/h in just 8.2 seconds. Its top speed is 200 km/h, and maximum torque is 280 Newton-meter (at 1,800 rpm). On average, the Tiguan TSI with 125 kW consumes 9.1 liters of fuel per 100 kilometers.
TSI with 147 kW / 200 PS
For the time being, the strongest engine on the new Tiguan will be the 147 kW / 200 PS version of the 2.0 TSI. Although its performance data match those of the engine used in cars like the Golf GTI, the engine used here represents a new engine generation. In this case, the maximum torque of 280 Newton-meter that is already available at 1,700 rpm remains constant up to 5,000 rpm. After just 7.6 seconds the most powerful Tiguan is moving at 100 km/h; and the forward propulsion does not end until 211 km/h. Average fuel consumption is identical to that of the 170 PS version at 9.1 liters of super unleaded.
TDI with 103 kW / 140 PS
Both TDI engines of the Tiguan are completely new developments. On the light 166 kilogram common rail TDI, injection pressures up to 1,800 bar produce especially fine atomization of the fuel. Eight-hole injection nozzles drive the state-of-the-art piezo injectors. The result in the case of the 103 kW TDI: 320 Newton-meter maximum torque at a low 1,750 rpm. Only 10.4 seconds elapse during the acceleration to 100 km/h. This Tiguan TDI reaches a top speed of 186 km/h. Its fuel consumption is 7.2 liters of diesel per 100 kilometers.
TDI with 125 kW / 170 PS
The more powerful of the two new TDIs with common rail injection outputs 125 kW / 170 PS. Its maximum torque is a considerable 350 Newton-meter (at 1,750 rpm). After just 8.9 seconds this Tiguan is already 100 km/h fast. Its peak speed is 200 km/h. This contrasts with an average consumption of 7.0 liters per 100 kilometers.
Six-speed manual and automatic transmissions
All Tiguans are delivered with six-speed transmissions as standard equipment. As an option, the two strongest gasoline engines (170 PS and 200 PS) as well as the 140 PS TDI may be ordered with a six-speed automatic. Both transmissions fulfill special off-road requirements. The manual transmission can be driven at an engine speed of 1,000 rpm or vehicle speed of just 6.69 km/h, for example; this practically equals the crawler gear of a reduction gearbox. The automatic transmission has gear level preselect; in off-road use it prevents shifting to the next higher gear.
4MOTION
In 1998 Volkswagen presented the highly advanced 4MOTION system as the successor to the fulltime “syncro” all-wheel drive. Over nearly a full decade, the all-wheel drive concept has been continuously further developed in various technical configurations. An important design property of the 4MOTION systems installed in car segments up to the Passat V6 FSI (another technology is used on the Phaeton and Tiguan) is the very quick reacting Haldex clutch. The latest version of this technology operates on the Tiguan.
The defined development goal was an all-wheel drive that satisfies the highest standards for driving dynamics and driving safety on the road, while simultaneously offering optimal traction off of the paved trails. In practice, this means: Hardly any perceptible additional fuel consumption, no effects on the engine and no running noises.
4MOTION details
The electro-hydraulic Haldex clutch runs in an oil bath. The multi-plate clutch system itself was integrated in the rear axle drive of the Tiguan; the entire unit weighs just 44 kilograms. As soon as speed differences develop between the front and rear axles, two annular piston pumps are activated that build up pressure in the multi-plate clutch and join the axles to one another. The transferable torque varies with the magnitude of the pressure applied to the clutch plates, and this controls the flow of force between the front and rear wheels according to specific needs and stepless. As soon as the clutch detects slip at the front axle, more engine torque is applied to the rear axle. Normally, 90 percent of the propulsive force is to the front wheels and ten percent to the rear. In extreme cases, however, nearly 100 percent can be transferred to the rear axle.
