I just returned my 2017 leased Bolt EV to my original dealer on Tuesday with 44,640 miles and started driving my new 2019 Bolt EV for Uber on Wednesday.
After two days of full time Uber driving, I can report this model has MUCH better battery efficiency.
While my results are still short term and anecdotal, yesterday I drove 224.5 miles on 53.3 KWh with 30 miles reported as remaining on the GOM and 12% of the battery shown as remaining on the MyChevy app.
The days driving was a mix of rush-hour bumper to bumper freeway driving (LAX to Ontario - 2-1/2 hours!), street driving and full throttle freeway driving when conditions permitted it on the way back to Los Angeles.
I NEVER achieved this kind of performance on my 2017 Bolt EV, even when it was new!
On a side note, it took my Clipper Creek 240v, 20 amp L2 charger 13 hours to complete a full charge, when in the past, under like conditions, it would usually do it in 11-12 hours and the GOM and MyChevy app is claiming 263 miles available!
