e: however, if Dom reached the maximum speed of the Hypersport at 245mph then L becomes 60,211 making a 50 foot jump potentially plausible! Hope he made a few laps around the top floor before he ploughed through the window!
Did you just say a car will take off and fly if it reaches 245 mph? Woah.

Physics goon here. Haven't seen the scene, but jumping a car without a ramp is a real bad idea. When your front wheels leave the surface, the car starts rotating, since it's only supported by the back wheels. By the time the back wheels clear, the car has acquired a significant angular momentum. While in flight it will continue rotating until it lands. Depending on how long the flight is, this can be A.) bad or B.) really bad. Since it was horizontal initially, it will be tilted forward when it lands, and therefore land radiator-first instead of on its wheels. Assuming you make it into the other skyscraper at all, which you probably won't because skyscrapers don't have enough space to get up a good speed, you're gonna crash your car.
The car is rear engined and has aero meant to place a moment on the car rotating backward so I'd be more worried about turning upside down and entering the next building rear end first.

Ballistic is the first thing to look at to see what is even the realm of the problem. Depending how fast you think he got it going, you are looking at 1/2 to 2 seconds of free fall if its only 50 ft between buildings. That's like 5 ft dropped best case, or 60 or so ft worst case. A story is generally what, 10 feet? In the movie it drops a handull of stories so its on the realm of made up but probably thought about for 5 minutes.

Nah it's just at that point it'd probably be going fast enough to cannonball between the skyscrapers after dropping however many stories. Probably not going to land upright though!
You calculated pounds force acting on the plane of the cars bottom though. If its greater than pounds force weight, also perpendicular to the plane of the cars bottom, by simple vector addition its going to fly. Its almost like a lift calculation doesn't fit the problem statement...

I drive a poo poo car so that means I get 30 seconds to be free. Seems like the better end of the deal.
