There was some discussion/comparison between the 2020 CR-V hybrid and 2020 RAV4 in the following thread - https://www.gen3insight.com/forum/521-general-automotive/3362-honda-crv-hybrid-coming-us-early-2020-a.html2020 CRV -hybrid is here....Plug Hybrid Toyota RAV4....what is the mpg? Better then our insight in the highway @70mph?
CR-V Hybrid = 43 city | TBD highway | 40+ combined (estimated)
RAV4 Hybrid = 41 city | 38 highway | 40 combined
Both are AWD drivetrains (and 20+% heavier vehicles), which makes the fuel efficiency lower than the Insight's FWD. Highway mpg for the CR-V hybrid is expected to be a little better than the RAV4 Hybrid, netting a slightly higher combined mpg.
EPA testing for all cars defines "highway" as 60 mph, so most manufacturers optimize their results for this speed. Fuel economy at >60 mph doesn't benefit a manufacturer in this reporting/results, so generally isn't a focus.
