Just got a T6 over the weekend. Couldn't justify paying double for a Model X and already have a Model S. In 3 years when the lease is done, maybe things will be different.
The XC90 replaces the minivan, so it is a huge improvement there. Without getting into a full review, I got the ICE T6 instead of the T8 for the reasons already stated above as to how the electrical power is being apportioned, extra weight, price, etc. The styling inside and out, I find, is ultra sophisticated and modern. Interior space is pretty huge, which you can't tell from the outside. I have the coil suspension and think it does just fine in suburban roads with great comfort and handling. Because of the small 4-cylinder engine (super and turbo-charged), this is a light SUV and find the lack of huge weight transfer on cornering to be refreshing compared even to my Model S. Of course, performance of the T6 is good compared to even V6s, but cannot be in any conversation with a Tesla. The Sensus system is a nice second best to Tesla's.
Overall, I'm happy: we have a stylish, capable, family hauler; the wife and kids are cocooned. I stopped short of going full-on green again, but hey, I gained about 3 mpg compared to the minivan [emoji12].
