Interesting twist of events, seems the French are interested in phasing out diesel fuel...

"In France, we have long favoured the diesel engine. This was a mistake, and we will progressively undo that, intelligently and pragmatically," Valls said.

never mind the cost driven motivations for those choices, typical socialist idealizing or are they actually onto something progressive?

It's also an opportunity to increase taxes!

New Diesel engines generates low emissions. Problem exist with old Diesel cars, without any filter or catalysator.

We will see how that goes for them. Man, France loves to tax things.

Diesel has issues, particularly particulate emissions. Gasoline engines are getting pretty close in terms of fuel efficiency, and have them beat for particulates and oxides of nitrogen by a lot.

Diesel produces about 10% more co2 per gallon burnt. When diesel was kicking the butt of gasoline engines in mpg, that didn't matter. With variable valve timing and gas direct injection bringing that difference down, it does.

The NOx and particulate issues contribute heavily to smog and are generally carcinogenic.

Add in the near future, diesel doesn't have a lot of options for improvement. Gasoline has variable displacement and camless engines on the horizon.

Then of course there is electric.

Odds are they want to stop incentivizing diesel and start incentivizing plug in series hybrids and EVs.

I've heard GDI engines are kicking out even more particulates than your average diesel.

It's true. From September 2014, all Diesel cars are Euro 6 compliant. Particulate emissions from actual GDI engines exceeds Euro 6 Diesel limits.

I can tell you that I can't stand to be behind a car/pickup with a diesel engine and quickly close my vents & windows if I happen to get behind one. The smell just rubs me the wrong way. At least the big rigs dump the exhaust up high so it isn't noticeable in an ordinary car.
