VW Iroc Twincharger: First employed in the Golf GT in 2006, TSI engines are currently the most efficient four-cylinder gasoline engines in the world. The combination of compressor and turbocharger shows the path to the future. The compressor compensates for the typical powering up weaknesses of turbo-only gasoline engines at low rpms. The turbocharger in contrast packs a mighty punch at higher revs. The combination of both superchargers in large-volume production engines is the only one of its kind in the world. The TSI version used in the concept achieves 155 kW / 210 hp. In principle, a large range of supercharged engines are conceivable for the Iroc that could start significantly under 110 kW / 150 hp. But there's one thing every engine theoretically employed in VW Iroc has to guarantee: Driving fun.


VW IROC FRONT END DESIGN

Radiator grill and headlights make unmistakably clear that the Volkswagen Iroc concept is more than a cruiser


Radiator philosophy: The new design expression of the Volkswagen concept shows that the Iroc is a car thoroughly designed for dynamics. A look at the front end makes this positioning emphatically apparent. There has never been a radiator grill of this shape for a Volkswagen. By doing so the company is manifesting the decision to use different "Volkswagen faces" for specific models and segments. This is already practiced for the Golf, for example, which features the typical Golf radiator grill in the Trendline, Comfortline, Sportline and Individual versions, but sports variations of the crest radiator grill for the sportier GT, GTI and R32 versions.


Hexagon of aluminum: The sports car grill specially designed for the Iroc concept is made of light, brushed aluminum in the outer areas. The honeycombed-shaped structure of the radiator grill has been a signature of the sporty Volkswagen since the debut of the current Golf GTI. Designed as a hexagonal air intake, the grill goes all the way down to the dark front apron. To the right and left of it there are two more air intakes for cooling the brakes. While the upper transverse web of the radiator grill is flush with the engine hood, the short side sections of the frame directly abut the xenon headlights. It is apparent here that the image of the radiator grill hexagon almost inevitably results from the connection of the headlights. The headlight casing itself is comparatively narrow and drawn up to the fenders in the modulation. Together with the radiator grill the headlights pay full honor to the Iroc's "viper green" paint.

V-shape up to the A-pillars: As a virtual continuation of the radiator grill lines two elevated and sharply cut flanges divide the engine hood into three sections. In the middle and a bit lower the largest of these surfaces continues the V-shape of the sports car grill up to the A-pillars. The A-pillars themselves are hard to see from the front, because the windshield is extremely wide and overlaps the pillars from the front. The two other surfaces of the engine hood descend into the exposed fenders of VW Iroc.


DESIGN SILHOUETTE

Marked C-pillars and window areas; large surfaces with a completely unique excitement

Statement of the surfaces: Whoever wipes his hand first across one of the headlights then over the fender and one of the doors will feel that the surfaces of the silhouette twist against one another. In particular the waistline above the front wheel arches and the door handles up to the upper edge of the rear lights drawn far to the side demonstrate this effect. Depending on perspective and the way the light falls this causes the side sections to look different each time, fascinating and like a taut muscle.
