After getting caught cheating on emissions testing by means of software, Volkswagen could face up to $18 billion in fines, reports USA Today. That number is based on the company being assessed the maximum penalty of $37,500 per affected vehicle. That's not the only bad news for Volkswagen, which has halted sales of its 4-cylinder diesel cars; the linked article reports that the violations "could also invite charges of false marketing by regulators, a vehicle recall and payment to car owners, either voluntarily or through lawsuits. Volkswagen advertised the cars under the 'Clean Diesel' moniker. The state of California is also investigating the emissions violations."
