The Ampera is here as an example of technology that's managing to sneak under the social radar and win the green game by stealth. It combines a load of realistic green technologies to produce a car that's practical and easy to use (this really could be your only car), at a price - £29k - that's easy(ish) to swallow. It's a plug-in - with an EV-range of 50 miles, so it may never need to see a fuel station. But it's also an ER-EV, or Extended Range Electric Vehicle, so the 1.4-litre petrol engine is never connected to the wheels - it's there to drive a generator, just like the Fisker on p140, and allow for an all-up range of 310 miles on one tank.
The battery is guaranteed for 150k miles or 10 years. With a full charge, it'll do the equivalent of 175-odd mpg and 40g/km CO2. So this is exciting new tech in a normal, useful package. An EV without the range anxiety. A green car without the sense of self-righteous anger. The future's bright. The future's quite subtle.
