Changes to the engine include refinements like a cogged belt to drive the camshafts in place of the old timing chain and a lighter crankshaft. The reduced weight will help the triple run smoother and reduce fuel consumption. The three cylinder is built at the Škoda plant in Mladá Boleslav in the Czech Republic. The factory produced over 270,000 of the engines in 2008. The revised engine will be applied to other VW Group models over the next year.
