Final paragraph from a stark VW assessment; also see The Real Winner in the VW Diesel Scandal? Hybrid Cars (Wired)

"Even if other makers of diesel vehicles have not resorted to the same level of deception as VW, the scandal could mean that these cars struggle to meet standards applied rigorously to both types of emission. Some fear that this may be the “death of diesel”. So be it. There is still scope to improve the venerable petrol engine; and to switch to cleaner cars that run on methane, hydrogen and electricity, or are hybrids. A multi-billion-dollar race is already under way between these various technologies, with makers often betting on several of them as the way to meet emissions targets. If VW’s behaviour hastens diesel’s death, it may lead at last, after so many false starts, to the beginning of the electric-car age."
