I see aerodynamic improvements, more efficient drivetrains and the proliferation of EVs as very notable changes in the last ten years. Many of these are similar to what Ecomodder members have been experimenting with in their own garages and detailing in posts on this website. Sometimes it feels like the big auto manufacturers are listening in. Fastback rooflines are becoming cool again.
We recently traded our 07 Grand Cherokee CRD and 11 A3 TDI for a 2017 Audi Q5 3.0T. The Q5 has a roofline that follows the "template", belly pans producing an almost totally flat undercarriage and an eight speed DSG transmission. I could only get about 24 mpg from the CRD turbo diesel on the highway, which I figured was pretty good for a heavy, four wheel drive vehicle. However, even with a gasoline supercharged three liter V6 the Q5 has been returning 30 mpg on the highway at 60 mph for a similar size, weight, towing capacity and all wheel drive. Amazing.
I have enjoyed being part of the Ecomodder community and have learned a great deal. Keep up the good work. I am looking forward to many more decades of innovation.
