The CX90 inline 6 will be hot garbage especially after the warranty ends. Its more complicated than any german invention I have ever seen, and the manual of repair on it...requires disassembly of the entire front clip and removal of the engine. How fun! This is straight from mazda's mouth too lol.Still dreaming here....and it has to do with being a car enthusiast imho.
If GM comes out with a refreshed Tahoe in 2025 that still has a V8 that supposedly gets redesigned to be more efficient, why not just jump off that cliff and get it (as a GM owner I have experienced the below average reliability and poor dealer network and attitude)...or it's Escalade sibling...we only live once. I've written off the CX90--the cargo space simply doesn't cut it for something so expensive....
The only way to make a v8 efficient will be to downsize and use cylinder deactivation, or hybridization, and use a good flow head and well designed intake plenum to manage air flow on the low end. I think something like valvetronic would do wonders for V8's to allow for precise air control while cruising. That and adding more gears.
Lets do a quick comparison. The Lexus RCF 5.0 V8 with the 8 speed gets 16/24 MPG (city/hwy), where as the same engine in a heavier weighted car but with a 10 speed (the LC500), gets 19/25. Gains are gains.
I think a lot of it has to come from using new techniques of engine management, as well as transmissions and tuning. The v8 will always have a special place in my heart, but it seems that everyone went towards the "cut cylinders" mentality instead of innovation. The corvette is pushing the limits, the stingray gets 15 city and 27 highway. And the E-ray Exists, and would be an awesome concept, to mesh a v8 into a hybrid system for better fuel economy.
But, there is always a but...WEIGHT...
