Honda has been using Auto Idle Stop on Pilot for several years to improve 1 MPG on EPA ratings. BMW 5 Series has been using similar feature to Mazdas i-stop for many years. Id think by implementing i-stop on CX-5, itd get similar increase on EPA ratings at least for city driving.I think that if the US EPA MPG testing loop included more stop and go, it would be implemented here as well.
Remember 2018 CX-5 with added cylinder deactivation gets only 1 MPG gain for FWD and 0 MPG gain for AWD on combined EPA fuel economy ratings.
If I were Masamichi Kogai, Id choose proven i-stop and i-ELOOP instead of cylinder deactivation implemented on US 2018 CX-5 if my goal is to improve 1 MPG on EPA rating!
