Mustang 500 GT, Camaro SS, Corvette, Charger and any other will beat it. It's not a fast car.
Well, firstly, we're comparing an american muscle car to a luxury electric saloon with autopilot, auto parking, auto lane changing and auto steering- so straight from the bat it's not exactly a good comparison. In specs, the top of the range 2015 Tesla Model S P90D has:
-532HP
-713LB/FT torque
-2.8 Sec 0-60MPH
For a base price of a 2015 model it is: $119,200
For the full fat balls to the wall super duper space ship version it's: $134,200
Virtually silent, very nice interior- it's a luxury vehicle.
And then the 2016 Mustang 500GT (This is the unreleased 5.2l version):
-526HP
-429LB/FT torque
-4.5 Sec 0-60MPH
For a base price it is:
-$36,395
-Unkown full fat price, not released
So, on paper, the Model S is a better performing, more luxurious car, however is more expensive- which is expected, since it includes carbon fiber everything.
I cannot find any drag races between the two that are fair. In the ones I did find, the Tesla was not the highest specced one, and the Mustangs were all highly modified. In those ones, the Tesla smoked the Mustang for the first 3/4 of the track, and then the mustang just pulled in front in the last second. This is due to the fact that the Tesla has nearly 300lb/ft of torque more, it is electric, and they have more instant torque, end of.
The Tesla is a fast car, it beats most if not all american stock muscle cars due to it's torque, however it is a luxury saloon, and is more expensive. It's not a fair comparison or a useful one. Although, for the value, the mustang is an amazing car and sounds better than the tesla any day- so personally I'd choose that, however also have the tesla as a long journey car.
I'm also not sure what two 8000+HP Top Fuel Drag cars burning 20 Gallons PER mile have to do with trying to prove how bad a 2-3HP 60MPH 1 foot long RC car is...
