Some companies, specifically Lancia, Toyota, and Volkswagen, are
looking into belt-driven superchargers for production cars.
VW has already installed one on a Europe-only Polo Coupe GT G40.  The
belt-driven supercharger boosts the 1.3 liter four cylinders' output from 55
hp to 115 hp.  VW claims it does 0-62 in 9 seconds and top speed
is 120 mph.  The type of belt-driven supercharger they are using produces
higher efficiency, lower noise, and is smoother running - 3
of big problems with belt-driven superchargers.  The article I read
stated early that another problem with belt-driven superchargers was
that they gulped fuel, but then never mentioned any mileage
statistics for the VW Polo.
