A few numbers I found interesting below...
14 CR technology = 6.0%
Improved Lubricating Oil 5W-20 = 0.5%
Weight Reduction by 5% = 3.3%
Weight Reduction by 10% = 6.5%
Weight Reduction by 15% = 9.6%
Rolling Resistance Reduction by 10% = 2.2%
Rolling Resistance Reduction by 20% = 4.4%
Drag Reduction by 10% = 1.8%
Drag Reduction by 20% = 3.5%
Alternator Improvements = 0.5%
Electric water pump = 0.5%
Idle Stop (advanced) = 2.5%
Fast engine warm-up = 0.5%

Interesting paper. Looks like (nothing new) that the US industry are years behind the EU and Japaneese car producers.
In the numbers you list above, I have to question the low % from drag reduction and the high % fra weight reduction, as we ecomodders again and again has proven that areo thrumps weight when it comes to FE.
We do they end up with the total opposite (and wrong) conclution?
