The male in the back left of the pic is 6'1", the female, 5'9". Front seat left female 5'10", driver 6'1". Notice the helmet clearance. It ran quicker than well over 3/4 of the sports cars (mostly light 2 seaters) at a tight Autocross (closed course time-trial roadrace, tight track), and even dusted a 2017 Chevrolet Corvette and Subaru STi WRX.

The mystery car has 110 cubic feet of interior cabin space, is AWD/AWS, weighs 4400lb, and gets >27 mpg highway at 75-85 mph (EPA highway 26 mpg). It has a 3 liter engine. Testing was done with babysitters "ALL OFF". No TC, No SC. Wearing treadwear 500, all-season tires, full depth, set at factory settings. Driver is an intermediate level skill driver. The electric version was a disappointment. I'm ashamed of the mfr. They could have made the PHEV version a World Beater but did not.
