"         &amp;quot;Downsizing&amp;quot; has emerged as one of the motor industry&amp;#039;s buzzwords. Usually it refers to switching from a large car to a small one, but in the case of the Volkswagen Golf GT, it refers to what&amp;#039;s under the hood.   VW&amp;#039;s Twincharger is based on the company&amp;#039;s 1.4-liter FSI engine and incorporates an Eaton Roots-type supercharger and a fixed-vane turbocharger. The trick is that VW has delivered a seamless switch between the two boosting systems, achieved through sophisticated electronic engine management and clever control of the incoming air for the supercharger and exhaust gas for the turbo.   The result is 168 bhp at 6000 rpm and 177 lb.-ft. of torque from 1750\u20134000 rpm. VW claims it knocks out 0\u2013100 km/h (62 mph) in 7.9 seconds on its way to a 137-mph top speed, and still averages 32 mpg.   At commuting speeds the engine is quiet and refined, with only a hint of supercharger whine to give the story away. It&amp;#039;s when you accelerate hard that the picture starts to change, with especially impressive torque delivery. The lack of lag and instant response to any throttle input, especially at low engine speeds, are quite surprising.   The Twincharger technology won&amp;#039;t spread across the entire VW engine range, and isn&amp;#039;t currently planned for the U.S. "^^<http://www.w3.org/2001/XMLSchema#string>
