It is time for volkswagen`s handsome hatchback to get a mid life uodate. and typically with all such model updates the polo gets minimalist visual changes and instead gets a bigger engine under the hood.the unit has been borrowed from the gt tdi, polo`s top of the line diesel lanched last year.however it has been downsized by around 100cc and is now a 1.5 litre four cylinder unit. power is also down by around a dozen horses to 88 bhp. but don`t be misled by the whole downsizing business because thish engine replaces the older 3 pot which was not necessarily quick.
