Hi All!
So I had a 60KW loaner the other day and enjoyed comparing the differences between a newer production (15XXX) 60kw to my slightly older s85 (60xx). One thing I found interesting is that the 60 was getting far better w/mi. than my s85.
I take the same route and know what my numbers pretty well since I have put over 10,000 miles on my 85. I can say conclusively, where my s85 would average about 350 w/mi the 60kw would average about 315 w/mi. Even when driving the 60 harder than I would the 85, cuz it's a loaner, I could not get the 60 over 320 w/mi.
I have a lifetime average of 349 w/mi on the s85 and it is my guess that I would average about 310 w/mi on the 60.
The 60 had 19" wheels, pano roof, and thats it. No tech, no fog lights, etc.
My s85 has 20" staggered wheels (8.5 front, 9.5 rear) loaded.
I'm thinking the wheels are some of the difference, but the weight and limited power output of the 60 might be the rest.
Thats a pretty big difference! About 10%+.
FWIW, The 60 felt a bit lighter, which it is of course, and quick, but it lacked the more neck snapping acceleration that my s85 has.
Any thoughts???
