BullishTesla’s new Roadster technology revealed in detail. Tesla Vice President of Vehicle Engineering Lars Moravy has publicly shared, for the first time, a comprehensive look at the highly anticipated new Roadster’s core technical details! This supercar abandons conventional design thinking, using a range of cross-disciplinary aerospace technologies and a groundbreaking powertrain layout to push the boundaries of what the market imagines electric vehicles can be.
Here are the key highlights:
1. Ditching all-wheel drive in favor of “dual-motor rear-wheel drive” + a dedicated 4680 battery
* Dual-motor rear-wheel drive: Instead of a tri-motor/all-wheel-drive setup, it uses a dedicated dual-motor rear-wheel-drive layout. Total power exceeds 1 megawatt (about 1341 horsepower), with torque topping 1400 N·m. An 8.4:1 planetary gear set independently drives the rear wheels.
* Lightweight, at just 1700 kg: The target vehicle weight has been reduced to under 1700 kilograms (it was previously planned to weigh 2000 kilograms).
* Custom 4680 battery: It uses an aluminum casing and titanium-alloy top cover, along with a double-sided, one-way cooling thermal management system to ensure performance doesn’t fade during 25-30 minutes of intense track driving. It supports an 800V-1000V high-voltage platform, with a target of completing a 15%-80% fast charge in under 10 minutes.
2. Active ground-suction system: cornering G-forces exceed 2g
* Underbody suction fans: Four 20kW fans powered by high-pressure compressor motors are fitted beneath the car. Working with four retractable skirts, they firmly “suck” the vehicle to the ground at low speeds, filling the aerodynamic blind spot.
* Active aerodynamic components: The front splitter contains adjustable 80° flaps. The rear-wing actuator directly borrows the leg actuator from the Optimus humanoid robot, enabling extremely precise downforce control.
3. Co-developed with SpaceX: cold gas thrusters (CGT)
* High-pressure nitrogen propulsion: Uses nitrogen gas at 10000 psi (about 689 bar) as the working fluid; it is non-toxic and non-flammable.
* Capable of short-distance flight off the ground: The top-spec Rocket version is equipped with a 600L compressed-gas tank and 6 thrusters, producing nearly 90 kN of thrust. This could help the vehicle briefly lift off the ground and correct its attitude midair!
In summary: The new Tesla Roadster is more than an electric supercar—it brings together Tesla’s advances in materials science, thermal management, robotic actuators, and SpaceX aerospace propulsion technology. There are already 4-5 prototype cars, and a large-scale test fleet is expected to get underway early next year.
