Proof of such can be seen in the Banks-tuned Volkswagen Jetta Sidewinder. The car is reportedly very similar to the Jettas that VW uses in its TDI Cup series, and the powertrain modifications include a cold-air induction system, a free-breathing exhaust system sans mufflers and a reprogrammed computer module. Inside, a 4.3-inch touch screen displays all kinds of useful data to keep track on the works.
Suspension bits are upgraded as well, as are the wheels and tires. The best news, though, is that the improvements have a positive impact on performance while not affecting fuel efficiency. Plus, the car remains 50-state emissions compliant. We'll soon be getting some seat time in the Jetta Sidewinder, so stay tuned for our initial driving impressions.
