Actually I totally agree with you that compact CUVs are gradually replacing sedans in the car market and I've been saying the same thing in another
thread. The reason I use Mazda6 and Camry comparison is 2019 Mazda6 has EPA fuel economy estimates available for both SA-G 2.5L and 2.5T so that we can easily to see the penalty on the same vehicle for more power. 2018 Camry has new 2.5L I4 and 8-speed step-automatic where 2019 RAV4 is going to have. EPA FE improvement on 2.5L from 2017 to 2018, 27/24/33 to 34/29/41, on Camry L is 26% which is unheard of. And this also comes with more power to boot, form 178 hp to 203~206 hp, a 14% increase! BTW these're all done by not using any thing fancy such as turbo、CVT、cylinder deactivation、or Homogeneous Charge Compression Ignition (HCCI). Now 2019 RAV4 is going to have these significant improvements both on power and fuel efficiency, added with industry-first "Rear Driveline Disconnect" and true off-road capabilities on its AWD system, I'm afraid even SkyActiv-X CX-5, which is a brand-new technology and several years away, can't compete with new RAV4 in these areas.
