The CLTC testing regime is ridiculous. They put the car on a dyno and then have it spin the speedo up to 50kph, 80kph, and 110kph for like 15km indicated on the odo to compute the range.

It's incredibly easy to show excellent range when there is no wind resistance to worry about and you don't have to accelerate the car's actual mass around. It's basically a test of rolling resistance. Not quite a perfectly spherical horse oscillating in a pure harmonic motion, but much closer to that then an actual road test. A good rule of thumb is to cut the CLTC figure in half to estimate actual range, cutting it even more if the car is especially brick like.
