For many years, diesel cars got a bad rep for being loud or stinky, and that reputation didn’t improve following the so-called ’emissions scandal’ a few years ago.

But the fact remains that diesel cars are cleaner and more efficient than they’ve ever been. What’s more, they can be a cost-effective option if you’re the sort of motorist who does a high number of miles every year, or drives long distances at once.
