Volkswagen’s twincharger petrol engine could be on its way out, according to well placed insiders.

The company’s 1.4-litre engine, which mixes turbocharging and supercharging, is said to be too complex and expensive to produce.

Instead, VW engineers now believe that new turbocharging technology can achieve similar results at a much-reduced cost.

The popular twincharger engine, found in numerous VW Group models, won the coveted Engine of the Year award in 2009 and 2010 and was described as “a masterstroke of downsizing technology and a real engineering showcase".
