It is. I was planning on getting the "long range" which is supposed to get 340 miles and 0-60 in 4.2. When I saw the "performance", I pulled the trigger pretty much immediately. 300 miles, 0-60 in 2.9. Took just under two months from order to pick up.
So far I absolutely love it. It makes my other car feel like a dinosaur. I still need to get used to the screen and the menus. I thought I'd hate not having a turn signal stalk or gear selector but it hasn't bothered me at all. The turn signal is "smart" and turns off on its own after you change lanes or turn.
It's really fast, it's really quiet, and it feels solid. Ride is better than I expected for a sporty car with big wheels and low profile tires. Already used the remote cooling feature to keep it at 72 while parked in the sun.
