Like magic! How to make high vehicle CO2 emissions simply disappear

Ask people on the streets in Germany who they think is the most famous magician ever, and the name you would probably hear most is David Copperfield. Almost everyone knows him and is fascinated by... On June 26, the BMVI finally published the CO2 measurement results we had been waiting for. But in the interim the Ministry re-tested 29 of the original vehicle models. Only a subset of those...

What EU cars’ CO2 emissions have in common with supermarket prices

When you think back to your most recent stop at the supermarket, you will probably recall that most of the price tags you saw ended with the digit "9". Maybe 99 cents for a chocolate bar and 49 cents... It’s about 15 times more likely that the official CO2 emission level of a new car sold in the EU is something-"9" g/km than something-"1”. And there’s a remarkable correlation between that...

Estimating the costs of vehicle efficiency: Will the European Commission incorporate lessons from experience?

Earlier this year, I wrote about estimating future vehicle technology costs, to make the observation that in reality meeting CO2 reduction targets has consistently ended up being cheaper than... Draft vehicle technology cost curves for post-2020 CO2 standard were presented to the European Commission in late July. Here's how they look in light of earlier (not always accurate) estimates.
