In Europe, diesel cars have received a lot of bad press because of the impact of their emissions on urban air quality compared with their petrol counterparts.
But for some people, those who drive a lot of miles, the higher fuel economy of diesel makes diesel powered cars cheaper, over the long term, to run. Higher fuel economy means CO2 emissions from a diesel car are lower too. So the incentive was there to clean up diesel and give consumers a viable choice that was better for their health, the planet and their pocket.
Regulators, quite rightly, also responded and set tighter emission limits to protect our health. Meeting these posed a technical challenge… exactly the sort of thing that JM loves best!
JM has applied its science and successfully reduced NOx emissions by a further 50%. In doing so, we have developed the most advanced catalyst system for diesel vehicles yet. Auto makers agree and have made it their number one choice. As a result, JM’s market position has increased by some 20 percentage points, to around 65%.
This all means a new diesel car in 2019 can run just as clean as its petrol equivalent. So consumers no longer need to choose between economics and the environment.
