So here it is: VW’s first attempt in the compact SUV category, the 2008 Tiguan. What do you think about it now that you’ve seen it without a trace of camouflage? We’re asking you that because, although we still think VW should have remained closer to the 2006 L.A. Show Concept, we’re not so negative about its styling as we we’re when VW unveiled a series of camouflaged images a couple of weeks ago. And a few words about the Tiguan in case you missed our previous post. VW’s RAV4 and CR-V contender will be offered solely with turbocharged engines: three TSI petrol units producing 150, 170 and 200 Hp and two TDI diesel units developing 140 and 170Hp. The Tiguan will make its official public at the Frankfurt Show in September with sales commencing in February 2008. -Click “Read More…” below for the official press release and a high-res image gallery

Like the Touareg, the second Volkswagen SUV also presents a self-confident design. Shaping the front of the new Tiguan are the sexy proportions that Volkswagen first introduced with the Concept A Study that garnered worldwide attention – a crossover of a coupe and SUV. On the sides an elongated and powerfully modulated silhouette spans between the extended wheel arches with a – typical Volkswagen – unmistakable C-pillar. A very short overhang characterizes the steep rear end. Also significant are the front headlights and rear lights with matching shapes.
First facts on Tiguan engines: Volkswagen will offer the SUV – and this for the first time worldwide – exclusively with turbocharged direct injection engines. This “high-performance turbocharging” significantly reduces fuel consumption and emissions, yet immensely increases dynamics and driving fun.
Overall there are three TSI and two TDI engines. Of these the completely new developments are the extremely quiet TDIs with common rail fuel injection. They achieve 103 kW / 140 hp and 125 kW / 170 hp and at 1,750 rpm already output 320 Nm or 350 Nm in four-wheel drive. Both TDIs already meet the limits of the Euro-5 standard first coming into effect in 2009.
Also getting to the point powerfully, economically and cleanly are the turbocharged direct injection gasoline engines in the performance levels 110 kW / 150 hp, 125 kW / 170 hp and 147 kW / 200 hp. New to the Volkswagen program are the 150 hp and 170 hp versions. A glance at the torque values makes one sense that the TSIs are very high torque. The 150-hp TSI already develops a self-assured 240 Nm (from 1,750 rpm). In the 170 hp and 200 hp performance range it is 280 Nm (from 1,800 rpm each).
“Tiguan Base” on the internet shows just how big the interest is in the new Tiguan. Visitors to www.tiguan-base.com can log in to the virtual world of the Tiguan. The development stages of the new SUV are presented in photos, films and facts. Within just 15 weeks – and this is sensational – more than one million people have made use of it worldwide. It looks as though the Tiguan is developing into an exciting chapter in the history of the automobile.
Apart from the obvious, meaning that the Tiguan’s appearance (in and out) is severely toned down compared to the 2006 L.A. Show concept, VW’s press release was surprisingly detailed for a prototype version that’ll be officially unveiled at the Frankfurt Show in September with sales commencing in February 2008. Beginning with the running gear, the Golf based Tiguan will be offered solely with turbocharged engines: the TSIs (gasoline) delivering 150, 170 and 200 Hp and the TDIs (diesel) developing 140 and 170 Hp.
Equipped with the same 4WD system (4Motion) that we find in various VW models, the Tiguan will be offered in two body variants differing primarily in their front ends: The “Trend & Fun” and “Sport & Style” versions are designed for a maximum entry angle of 18 degrees in front while the “Track & Field” Tiguan is tuned for offroad duty for max entry angles of up to 28 degrees with its front end. However, undoubtedly, the highlight of the Tiguan is the standard Offroad Mode system in the “Track & Field” version that activates a bunch of assistance systems like the hill descent control and electronic differential locks by the touch of a switch -think of it as a simplified version of Land Rover’s lauded Terrain Response System. –Check out the press release along with 18 high-res images after the jump
The New Tiguan:
Completely new electronic systems also simplify offroad driving in the 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.
THE TIGUAN VERSIONS
Innovation: All engines of the Tiguan are charged.

Two front ends. The two body variants of the 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.

THE TIGUAN CHASSIS
Front axle: McPherson system with aluminum support frame.
Rear axle: Innovative four-link rear axle is ideally matched to the four-wheel drive system 4MOTION.
Long before the first prototype was built, it had been decided that the new 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
Front axle. The demands are achieved with a chassis layout that sets standards in this class: at the front end, the Tiguan has a McPherson axle specially optimized for the SUV with lower A-arm steering linkage and the wheels hung from damper struts. The axle is located with a one-piece aluminum sub frame.
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 Tiguan is specially intended for this combination. The extremely robust, but at the same time dynamically laid out axle geometry has already proved itself in the Passat 4MOTION. However, to cope with the stresses of offroad driving, the Tiguan has an entirely newly developed and weight-optimized high-strength steel sub frame instead of the equivalent aluminum component.
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.
Wheels and tires. Providing contact to the road or trail on the base versions of the Tiguan are 16-inch wheels with 215/65 R16 tires. The “Sport & Style” Tiguan also has as standard 17-inch alloy wheels and 235/55 R17 tires. 18-inch wheels with tires in 235/50 R18 format are available as special equipment.
TIGUAN ELECTRONICS
Innovation: First Volkswagen with a new generation radio and navigation system.
Safety at the press of a button: offroad switch activates network of assistance systems.
Also in the area of electronics, the Tiguan was designed to set new standards in the compact SUV class. Typical of Volkswagen is the high standard it sets for making the interface to the driver as comfortable as possible. An example of this on the Tiguan is a newly designed radio and navigation system generation. The software and hardware of this new system fulfill the highest demands for operation, sound and the multitude of functions offered.
The RNS 510. A glance at the top device – a radio navigation system with the designation RNS 510, emphasizes this impressively. The RNS 510 is controlled using fixed menu buttons, two knobs and a touch screen for the numerous information, entertainment and system functions. In this case a rear-view camera eases the view behind, a standard fitting.
The hardware of the RNS 510 includes a 6.5” wide VGA color display with 800 X 480 pixels and outstanding brilliance. A power PC processor with 400 MHz and its own graphic processor enable fast computing. The navigation and entertainment data are saved on a 30 GB hard disk. It is also possible to incorporate accessories into the RNS 510 like the telephone control, an iPod and other MP3 players. Combination with a Dynaudio sound system is also possible.
Offroad navigation. A further innovation of the RNS 510 is a specially developed offroad navigation system. This mode makes it possible to record up to 500 route points during a journey, even in non-digitized areas. This allows the driver to find his or her way back from offroad adventures into any desert or steppe. In edit mode, the driver can modify the route as desired. A glance at the map in the RNS 510 display offers the required orientation.
Park Assist. The further countless high-end technologies on board the Tiguan include the world’s first park steering assistant to be installed in a SUV. This is called Park Assist and enables automatic steering into a parking space.
Offroad Mode. The core capability of a SUV – offroad function – will also be dealt with and perfected electronically in the new Tiguan. And this through just one switch, which activates the Offroad Mode. This will be offered exclusively on the Tiguan “Track & Field” and will improve offroad vehicle handling significantly. The initial idea behind the “Offroad Mode” was that all key offroad support functions should be activated by a central user control. Specifically, one switch activates the “hill descent assistant” (for optimal control on slopes), “adaptation of driver’s pedal characteristic” (for finer gradations of torque), “EDS adaptation” (electronic differential locks are activated at the slightest slip), “ABS adaptation” (improved braking action on loose road materials), “hill climb assist” (support when climbing and protection of the clutch) and – in conjunction with automatic transmission – “gear preselect” (including optimal engine braking action). These numerous functions involve up to five ECUs that manage the systems.
The pushbutton itself is connected to the engine controller. From there, the information “Offroad Mode active” is communicated to other ECUs via the vehicle’s CAN bus. For safety reasons, the function has to be reactivated after each ignition cycle.
Just how “intelligently” the electronics react is demonstrated by considering an offroad driving situation that is not all that uncommon: An engine stall can even happen to professional drivers offroad. This deactivates the Offroad Mode, and assistance systems are turned off. But the electronics of the Tiguan detects this as a “stall” and when the engine is restarted all offroad assistance systems are up and running again immediately.
