2019 Volkswagen Thunder Bunny Concept
Volkswagen introduces a concept vehicle that reflects its roots in the sport compact tuning community. The story began back in the early '80s, with a man named Bill Neumann. Bill founded the California based tuning firm Automotive Performance Systems (APS). He was frustrated with the fact that Volkswagen's hot hatchback GTI had been sold in Germany since 1976, but hadn't yet come to America. Bill had driven the GTI in Europe on several of his parts-searching trips, and he was convinced it would be a big hit in America. So he sent letters to the factory. He wrote to enthusiast magazines and lobbied Volkswagen dealers for support. Then, he put together the proof that a Rabbit-based performance car was capable of generating both stunning performance numbers and lots of attention from the American automotive press corp. Thus was born the original Thunder Bunny. The APS-modified Rabbit was delivered to Motor Trend magazine late in 1981. Even though its staff was use to driving the best cars in the world, they were blown away by the little Volkswagen hatchback.
Bill's frustration ceased in the fall of 1982 when the GTI finally came to America, but by then Thunder Bunny had done its job. It put Neuspeed, the APS-trademarked line of parts and accessories, on the map. It also helped launch a vital North American community of specialists in watercooled Volkswagen performance. Modifying Volkswagens, of course, was not new in America 鈥?the Beetle had spawned a huge following of enthusiasts 鈥?but the new generation of Volkswagen cars hadn't sparked much interest in the go-fast crowd before the early '80s. Neuspeed continues to be a leading force among the world's Volkswagen tuners, and it has never stopped building special projects. The latest is also called Thunder Bunny, and it was built in commemoration of Neuspeed's quantum leap forward all those years ago with the original rabid Rabbit. Today's Thunder Bunny is a blend of subtle design massaging and tuning technology, built to show how a comfortable daily driver can also provide an exciting motoring experience.
Creating the thunderous noise from under the hood is a newly developed turbocharger system, designed by Neuspeed especially for Volkswagen's 2.5-liter five-cylinder engine. The high quality installation includes a modified intake manifold, Garrett ball-bearing turbocharger and air-to-air intercooler. A stainless exhaust and specially baffled aluminum oil pan were also sourced from APS for optimum flow and cooling. Boost is restricted to a maximum of seven lbs. Stage 1 kit, but it still produces 225 horsepower, 75 more than the stock 2.5 L, and a hefty dose of low-end torque. A performance clutch and Quaife differential were added to the powertrain for durability and a more efficient delivery of power to the front wheels. Thunder Bunny's gleaming candy white exterior is made distinctive by several design studio touches. The concept's body kit includes a larger central grille and a more muscular rear valance framing a twin R32-style exhaust from Neuspeed. Like the R GTI, Thunder Bunny's paint was overlaid with graphics Jenkins calls "topographical" in pearl silver. They were meant to evoke the contours of the car's geography or waves of air that flow over the surfaces.
However they are interpreted, the pearl silver graphics make a unique visual statement as they appear to blink on and off in the changing angles of the sun. Like the original Thunder Bunny, the forged alloy "street" wheels are painted gold. In 19x8-inch sizing, they're wrapped with Michelin Pilot Sport Cup 235/35-19 tires. Similar sized multi-spoked forged alloys were sourced from Neuspeed's RS line of wheels for track use. Both sets are lightweight, in keeping with the core GTI quality of nimble handling. The front brakes are 328mm two-piece floating cross-drilled discs from Brembo, gripped by bunny-bedecked Brembo four-piston brake calipers. That's right, bunnies. A veritable warren of Thunder Bunny logos dash to and fro across the surface of the white-painted caliper. At the rear, 310mm disc brakes are fitted. Handling prowess comes from a suspension fitted with a Bilstein coil-over shock system and APS/Neuspeed sways bars, measuring 25mm front and rear.
