After weeks of extensive road testing, several motoring journalists have reported a suspicious noise coming from under the hood of the new EV from Volkswagen. While many happy owners suspect a minor mechanical flaw, several experts have voiced a surprising, unexpected theory: to extend the EV's range, the car occasionally switches on a hidden diesel engine.

The majority of journalists and motoring enthusiasts do not believe the allegations, claiming that a company like Volkswagen would not dare to deceive their customers and governments.
