2019 Volkswagen Tiguan Prototype
Volkswagen will complete the development phase of the new Volkswagen Tiguan with a final extreme test in Namibia. During the final acceptance drive on the African continent, the electronic components and chassis of the new SUV are the primary focus of testing. Considering the electronics, a technical highlight on board the VW Tiguan is of special interest for the testers: the completely new generation radio and navigation system. This was developed in close cooperation with the most important local Volkswagen operations in Europe, Asia and America. Worldwide development collaboration made it possible for a wider than ever pool of specialized know-how, and also the requirements of all markets, to influence the devices. The top system of the new line, with the designation RNS 510, has a 30 GB hard disk and is controlled with a touch screen. A rear-view camera enables a view behind in this case. Completely new electronic systems also simplify offroad driving in the Volkswagen Tiguan. The particularly agile and dynamic SUV uses an innovative network of assistance systems with the name of "Offroad Mode".
Just on touch of a switch activates a whole armada of safety features, supporting the driver in a multitude of situations. Five motors. All of the engine and body versions of the VW Tiguan have to "swallow" the dust of Namibia in this final test. Volkswagen will be offering the SUV - and this is unique so far - exclusively with charged engines. The TSIs (gasoline) output 110 kW / 150 PS, 125 kW / 170 and 147 kW / 200 PS; and the TDIs (diesel) develop 103 kW / 140 PS and 125 kW / 170 PS. Two front ends. The two body variants of the Volkswagen Tiguan differ primarily in their front ends. The "Trend & Fun" and "Sport & Style" versions are designed for a maximum entry angle of 18 degrees in front. The "Track & Field" Tiguan that is tuned even more for offroad duty can assume entry angles of up to 28 degrees with its front end.
During the testing program in Africa, as however already mentioned, the emphasis is less on engines and entry angles than on final checking of the electronics and chassis. Long before the first prototype was built, it had been decided that the new Volkswagen Tiguan should be an extremely actively driving and safe SUV. The development team pulled out all the stops to achieve this goal. The Tiguan now has to demonstrate in Africa that it achieves neutral to lightly understeering handling and an unusually low roll angle. Furthermore, the road holes along the edge of the Namib Desert should once more test how well the highly dynamic driving characteristics and excellent ride comfort interact under the hardest conditions. Because the demands on the car were clearly stated in the specification: to set benchmarks in dynamics, comfort and active safety. Rear axle. The four-link rear axle has also been adapted to best suit the permanent four-wheel drive system 4MOTION. The four-link rear axle of the VW Tiguan is specially intended for this combination.
The rear axle of the front-wheel drive Tiguan has been modified correspondingly. Items no longer found on board include: Cardan shaft, rear final drive and drive shafts. But the sub frame is utilized in both drive variants. The innovative modular system of this rear axle has a decidedly positive effect on costs. For the rear axle, newly developed shock absorbers were developed with increased oil volume; a favorable temperature level makes the absorbers well equipped for even the toughest offroad use. Like the front damper struts, also newly developed, both components provide for exceptionally good ride comfort properties. A new generation of steering. A technological highlight in the indirect chassis area is the completely new generation of electromechanical power steering. A decisive advantage of the system: Despite the very precise steering feeling, even in offroad operation no jolts whatsoever are transmitted to the steering wheel. Primarily responsible for this is a newly constructed steering gear.
