Renault Study Shows Cars Far Greener Than France

Facelifted 2013 Fluence electric sedan

relatively few electric vehicles on the drawing direct comparisons regular gasoline and diesel is surprisingly difficult—not many are sold with all three The Ford Focus is one, and Fluence sedan is another.

reports Autoblog Green . the automaker has revealed findings a study to determine which is over the vehicle’s lifecycle.

the electric Fluence Z.E. out on top, ahead of its gasoline and counterparts—though not without a few caveats.

The findings stem from an Renault study published in 2011. It’s based on production variants of each model—gasoline, diesel and electric—and on a vehicle lifecycle of 93,205 or a nice round 150,000

Both the 1.5-liter diesel and 1.6 gasoline model are relatively for their type. Although against the optimistic European cycle, the diesel’s 4.4 liters/100 km translates to 53.5 mpg, CO2 emissions of only 115 g/km.

A number-juggling converts the Fluence efficiency figure of 0.14 into 22.5 kWh/100 than that of any electric car in the U.S. (a Leaf uses 29 mi) but once again, this is based on the European drive so isn’t comparable to the EPA’s

Quantifying impact

The Fluence’s assessment (LCA) was measured in six Global warming 100-year acidification potential, photochemical creation potential, eutrophication abiotic resource depletion and primary energy demand. of these was then measured the four periods of a car’s well-to-tank, use, and recycling.

all sounds rather complicated you can read how each is measured at Car Congress ) but the upshot is that all but one of the six LCAs, the Fluence Z.E. was than its combustion cousins, so on a couple, including global potential. Here, it’s around 60 percent that of the and less than half of the gasoline model.


Where the electric car didn’t so highly was in the acidification potential This was mainly down to the Z.E.’s production stage, results in higher oxides of and sulfur dioxides.

Given each car in the study is a Renault the discrepancy is down to production of the lithium-ion battery pack, than other differences the models.

While of the numbers are unsurprising and back up of similar studies. Renault’s also illustrate how important a grid is to an electric car’s cleanliness.

This is illustrated in comparison between each of the factors in France, to those of a average and to the coal and gas-heavy Britain (GB) market.

largely nuclear-powered grid has 70 percent of the global warming of Europe as a whole, while GB is 140 percent of Europe. With impact pegged level the board, the vast majority of difference is down to the well-to-tank in each country.

An independent review of Renault’s revealed them to be fairly

While some factors missing from Renault’s into electric vehicles, the also pointed out that emissions from internal vehicles are often significantly than Renault’s +15% to swing the charts heavily in of the electric vehicles.

Ultimately, electric cars are already than their combustion in most key areas, even on grids. But run them in a country France—or run them from own renewable sources—and there’s to touch them.
