Over the last 5 years in my Model S, I've gone 70,147 miles, consuming 6,001 kWh, which averages 333 Wh/mi. I've found that the Tesla figures show battery Wh and not the wall Wh - I add 20% for charging overhead. Your utility bill should show you your local cost per Wh so you can get the figures for cost/mi.
I figure I'm paying about 25% of the cost of gasoline. (Though I use solar and get the advantage of an EV electricity rate plan and only charge at off-peak rates).
Tesla has both 2-wheel drive & 4-wheel drive (D designation for Dual motors or 4-wheel drive).
The story I heard (again 5 years ago) from one of the T engineers who was testing the 4-wheel drive car was that while testing up in the Northern states the T engineering asked the Controls vendor why he wasn't seeing any requests for reverse power from the anti-skid controller. That engineer said there was too much delay for the transmission, drivetrain, etc to give a good response. T engineer said he could give 100% reverse power as fast as forward power (i.e. instantaneous). Controls guy spent his nights rewriting the code to ask for 100% reverse. Tesla got what no other company had for 4wd. The 4wd model is more efficient than the 2wd model because the front & rear drivetrains use different gear ratios and the Tesla electronics decide the best one to use.

Also just got a Model 3 and it is more efficient than the S. Don't have a valid sample to say how much more efficient yet. The M3 4wd is due out late 2018.
