We all know greenhouse gases are all in the news the last decade or so. On top of that, fuel dependency gets a lot of airplay. Those two things drive a lot of the decision making for car fuel economy standards. In the US, that’s translated into a rather arcane system called the CAFE (Corporate Average Fuel Economy) standards. Jalopnik has a pretty good breakdown explaining the logic and implications behind CAFE standards. CAFE regulations have had a huge impact on car development around the world, particularly in the US. Ever wonder why small trucks like my personal favorite, the VW Rabbit Truck aren’t made anymore? Completely counter to logic, it’s actually the CAFE standards that have driven these more efficient vehicles out of production. Ever wonder why modern small cars go from pristine to ‘totaled’ even in relatively small wrecks? Again, CAFE standards drive much of this. Yet most people really don’t understand how and why CAFE standards work.
If you’re even remotely interested it either fuel economy, greenhouse gas issues, or cars, check out the link for a great breakdown. It’s really worth your time.
