Its just easier to market "turbo" compared to "hybrid" even if a hybrid offers the same if not better results. Ironically the name "hybrid" is a dirty word with tons of people. People think "turbo" they think fast, technology, Porsche 911 Turbo etc....
Case in point, my old GS 450h was the most understood Lexus I ever owned. It was clearly obvious over my time owning it that people still had no idea had hybrids worked and were oblivious Lexus offered them. I can't imagine how tough of a hill climb it is for Lexus to sell that car, thus why its now special order only. Back then it was 339hp getting 23 MPG average which was pretty impressive, today it has the same hp rating but gets over 30MPG!
Obviously cost is another reason they don't sell well. Not sure how Lincoln worked the numbers but their hybrid offering is the same price as the gas model so that helps make the choice easier.
Many of us know Brian, he is as good as it gets in the business and he's right. Currently the word "turbo" is attractive to consumers. All the issues the Germans had didn't sway public opinion.
Again though, my concern being deep in car culture, will Lexus let us tune these new engines. The Germans keep them open source and it is hugely, HUGELY appealing to enthusiasts. Imagine being able to tune your Lexus with some software updating that remaps the ECU and boom, 50-100 more hp. Unfortunately I doubt it
I posted a picture of the car because it looked like any GS except for the small h badge ( I replaced the grill with an aftermarket one) and people would be stunned to know its a hybrid. I really miss the car, the blend of power and MPG was really nice to have. It was really rare especially a modified one.
Turbo has lost a bit of coolness since it is now so mainstream. Even the base Porsche's are now all Turbo's.
