Powertrain and Battery
The Roadster 2 will be rear-wheel-drive only, a departure from Tesla’s track record of all-wheel-drive EVs. Two motors will deliver over a megawatt of power (1,341 horsepower) and over 1,400 newton-meters (Nm) of torque, meaning this car will have more torque and power than a three-motor Plaid. But all of that power goes through just the rear wheels.
The car will be light, at “just under 1,700 kilos” (under 2 tons), according to Moravy, not significantly heavier than the original 1,300-kg (1.4-ton) Roadster, despite a larger size.

Sucking Fans
At a 2013 auction, Elon Musk bought the iconic "Wet Nellie" Lotus Esprit S1 submarine car from the 1977 James Bond film The Spy Who Loved Me for just shy of $1 million. Musk is so taken with his Bond memorabilia that it apparently inspired one of the Roadster 2's key abilities.

That submarine Bond car has four propellers at its rear, so Tesla decided to ape this with four 20-kilowatt fans on the Roadster 2. Moravy says these fans break the laws of tire physics and dramatically increase the EV's traction by becoming what Tesla calls the car’s “sucker system.” Four independent replaceable skirts drop down on the sides of the car, allowing the Roadster 2 to stick (or suck) to the road at lower speeds where its aerodynamic wings aren't yet contributing to downforce. Moravy claims the system can produce over 2 g's in a corner when accelerating, even below 50 mph.

This type of aerodynamic manipulation also appears on the McMurtry Spéirling Pure, which uses two high-speed electric fans spinning at up to 23,000 revolutions per minute to actively suck air from underneath the chassis, generating up to 2,000 kg (around 4,400 pounds) of downforce.

This extreme suction lets the Roadster 2 drive up the vertical ramp at the Texas demonstration and hold onto the surface even when upside down.

Rocket-Powered Thrust
So how does the Roadster 2 hover, correct itself, and dampen its fall? That's thanks to what Tesla calls the car’s “SpaceX system,” referring to Musk’s aerospace company, which helped with this part of the car’s development.

Originally, the Roadster was meant to have a 2+2 cabin. Now it’s a two-seater because behind the seats sits a 200-liter carbon-overwrapped pressure vessel (COPV) that holds up to 10,000 PSI to supply the car’s cold gas thrusters, which use expansion of pressurized nitrogen gas to generate thrust, a tech predominantly used for spacecraft stabilization. Cold gas thrusters are the simplest manifestation of a rocket engine.

This combination of suction system and thrusters helps the car hit 0 to 60 mph in supposedly under a second. In this launch mode, Moravy says the rear thrusters produce more than 80 kilonewtons of thrust, which, staggeringly, matches the Dassault Falcon 10X jet. Tesla has seemingly cracked the sub-second race, while the aforementioned McMurtry Spéirling Pure can only manage this feat in a bowel-clenching 1.3 seconds. During this astonishing acceleration, the driver will endure up to 5 g's.

The Roadster 2's Performance model will feature the sucker system and no thrusters, so 0 to 60 will take a touch longer at 1.6 seconds and a top speed of 210 mph. The Thrust model gets the whole package and a top speed of 230 mph.

This “flight system” also requires six extra thrusters: one in each corner, plus two at the front to yaw.

Bursting the Balloon
Unlike in space, where cold gas thrusters provide consistent levels of thrust until the last drop of fuel is used, on Earth the “flight system” will lose thrust as the compressed gas depletes.

Apparently, refilling the 600-liter nitrogen tanks takes Tesla six to seven hours, but the company is supposedly working on a system to dramatically reduce this to 30 minutes.

The current Roadster 2 prototypes are being used for further development, and production won’t begin until 2028—but remember that Musk previously said Roadster deliveries would begin in 2020, so take this with a very large pinch of salt. That's without talking about how the Federal Aviation Administration will react to this "flying" car.

A lot of uninformed chatter on the interwebs that it is just a hollowed out prop that doesn't even qualify as a car.
