Diesel engines still have quite a potential, much more than petrol engines. The problem is the German carmakers have been careless: caring more about profit margins than proper eco tech. They know the tech, they know the solution but they don't use it because the cars will be a bit more expensive to make (decreasing corporate profit margins below the beloved 8%), and the power performance will be a bit worse.
Now they don't know what to do in this transitional period towards fully electric cars: to go for really clean diesels, or to go more extensively petrol-electric (hybrid).
