It's all thanks to a venerable Cummins inline-six turbo-diesel…

...the idea that modern diesels are part of the solution rather than problem is gathering pace, the arguments now backed by the results of the new, tougher-than-ever WLTP test regime that has been rolled out across Europe and which - even attackers of ‘old’ diesels are starting to admit - are proving the significant gains that have been made.
To my thinking, getting from where we are today to where we want to be in 2040 requires a glidepath, powered by improving technology. The fastest way to reduce emissions is to get newer vehicles on the road, and the knock-on benefit of that is that car makers will have more money to invest in newer, cleaner technology. The happy aside for government, meanwhile, is that a buoyant car industry is a hugely profitable one for its own coffers, especially as far as VAT on new car sales is concerned.
Diesel - sold wisely, used well - can be part of that solution.
