That is an unfair comparison given the huge frontal area of CX-5. That said, my CX-5 gets same city MPG as my 2007 Civic. My CX-5 gets 32MPG in mountain drivng which is far better than my 2007 Civic. The Civic beats the CX-5 in high speed highway driving due to huge wind resistance.
A fair comparison would be your 2002 Inginiti G20 to a 2015 Maxda3 /w skyactiv.
Mazda3 has over 30% better MPG and more power too.
2002 Infiniti G20 2.0L w/4-speed Auto____ 2015 Mazda3 2.0L /w 6-speed Auto
Horsepower: 145 hp @ 6000 rpm________ Horsepower: 155 @ 6000 rpm
Torque: 136 lb-ft @ 4800 rpm__________ Torque: 150 lb-ft @ 4000rpm
Compression Ratio: 9.5 : 1____________ Compression Ratio: 13:1
EPA MPG: 23/30_____________________ EPA MPG 30/41
Curb Weight: 2961 lbs _______________ Weight: 2918 lbs.
Mazda3 with 2.5L engine only loses 2mpg, but gains 185hp/184lb-ft. Infiniti G20 is fuel eating slug in comparison.
Skyactiv is a huge gain over competitors too. 15% more power, and 15% better MPG due to figuring out a way to run 13:1 compression with 87 octane gas. No one else can do that. The hybrid six speed transmission with low speed torque converter and use of wet clutches above 5mpg preserves the fun factor while increasing MPG. Others have resorted to CVT for efficient transmission, but horrible driving experience.
I really wonder how much difference the better aero and that slick 6-speed auto over the 4-speed slush box makes.
However, I did not take into account FRONTAL AREA of the SUV. I bet the SUV is "slicker" than the G20, but you can't argue with frontal area.
I am quite happy with my CX-5, I guess I just don't appreciate everything since it's not actually fast, etc. but when you break it down like such, I can see the engineering working for me somewhat. I would point out though that the RAV-4 doesn't use a CVT and it makes similar power, and in AWD trim only gets 1-2mpg less (it is also a 3500#-ish 6-speed auto with AWD and similar aero, if I had to guess). It also runs on 87 octane. So, all-told, it looks like all that technology is worth about 10hp, and 2 mpg. Not bad, honestly. I'll take it!
