Taking the Austrian electricity mix, the two electricity have caused in the test 31 or 33 g CO2/km - very good. In Germany, there were 111 or 122 grams - electric cars are so only as clean as the electricity used to charge.

But even under the worst generating conditions electric cars are still cleaner than gas cars--especially as the gas cars age and become out of tune.
This isn't true.
That's weird. I've seen other reviews that say ~80 km (50 miles) of range real world range on Fluence ZE vs ~100km (60 miles) on the Leaf under the same circumstances:
http://driving-dutchman.com/renault-fluence-ze-review/The battery package delivers 95 hp and has a capacity of 22 kWh, yet the Fluence Z.E. uses 23 kWh every 100 km (60 miles). The average distance during normal use and with a full battery has proved itself to be around 80 km (50 miles). This is not even half of the 185 km (115 miles) Renault promised in the specs of the Fluence Z.E.
The Nissan Leaf http://nissan-leaf.net/for example has an average drive distance of 100 km (60 miles) measured under the same circumstances.
Each kWh of energy produced by a coal power plant emits about 2.17 lbs (0.984 kg) of CO2.
Each gallon of gas burnt creates about 19.4 lbs (8.800 kg) of CO2. A gallon of gas produces about 5.4 kWh of useful work, or 3.59 lbs (1.628 kg) of CO2 per kWh produced.
Similar gas and electric cars use the same amount of power to move at any given speed so replacing gas cars with electric cars would reduce the amount of CO2 pumped into the atmosphere. Exactly how much depends on the mix of coal to other energy sources. But even with 100% coal it's still an improvement.
More importantly, the amount emitted from power plants is stable and controllable without using rare earth elements as catalytic converters do. Yes, they only use a few grams, but a few times millions becomes a big number.
Finally, electric cars can be cleaned up by replacing coal power plants with clean nuclear and other power sources. It only takes political will (and money). A gas car is as clean as it will ever be when new, and deteriorates over time.

This isn't true.
These results are not achieved on the same day. Look the date of Fluence review. Winter is not good for EV.
Look this other comparative, at same date, same temperature. Nissan 94 km, Fluence 119 km:
Nissan Leaf contre Renault Fluence Z.E. Expression - Match d'avenir? - Essais - L'Automobile Magazine
And Zoe is better than Fluence. The choice in Europe is clear.
"Because the air resistance and engines that run faster than 130 km / h (the ZE is designed for 135 km / h max and the Leaf to 145 km / h) in a zone scheme where their yields are deteriorating, drive up consumption sharply on motorways.
This limits their autonomy frankly: 67 km to the Leaf, and 76 km for the Fluence ZE, which operates 22 of 24 kWh total capacity of the battery, against only 20 kWh used in the Nissan. And distrust with which the Leaf alert late on the limited autonomy. The first beep occurs when there are only 6 km! (20 km for the Fluence). On the road, according to our measurement protocol ISO 9001, the range of the Japanese is 85 km, while that of the French climbs to 108 km. Finally, downtown, the Nissan will travel 94 km before requesting a refill, while Renault will grow up to 119 km."
So the emissions in this case are 142g/km.
This compares with (for example) 89g/km for a regular Prius under the same conditions. Even allowing for 17% refinery loses, there are many similar size cars that come in under 142g/km.
Range:
Fluence, 135 km
Leaf ,126 km
C30, 106 km
