1% on brake drag, huh?

Power steering is next to nothing now that hydraulic systems have been replaced by electric.

it's different on the hybrid model of the same SUV shown, as there is still some DIY improvements on the hybrid model that could take it down to 0.30 from 0.34 (the one shown is 0.367 or 0.38) considerable improvement over the previous model design which is 0.45 and the model design before that was 0.55 or higher (think square box shape)... the 2015 models are 0.34 as well as the 2021 model .


the 2015 only had a 2mpg gain going from the 2014 to the 2015 model.... and that gain is from the 8 or 10 speed transmission mostly..

I should watch an EPA cycle someday. 10% braking on the highway is absurd. Only time I touch the brakes on the highway is if someone cuts me off.
