Tesla Roadster: reservation price at 212,000 or 1,022,000 zlotys. RWD drive (!), 200-liter fuel tank behind the seat for ONE flight

Technical details about the new Tesla Roadster are coming to light, along with the option to reserve the vehicle. The total cost (down payment plus interest confirmation fee) is 212,000 zlotys for the Performance version and 1,022,000 zlotys for the Thrust version, of which 22,000 zlotys must be paid immediately while the remainder is to be transferred within 10 days. These are not yet the final prices for the Tesla Roadster II, as they have not been announced — potential customers are being tested to see how much their wallets can handle.

New Tesla Roadster, Technical Details

Among the models listed, only the Performance version promises road homologation, at least in the United States. The Thrust variant with additional rear thrusters cannot be legally used on roads, and the Rocket edition featuring bouncy handling and jumps (currently without a price) is available only by invitation:

The Tesla Roadster Performance sticks to the road thanks to a total of four fans (Image 1) that draw air under the car and blow it out at the rear. Each fan has a power output of up to 20 kW, working together with four additional flaps located on the edges of the car. When the electric vehicle first drove onto the ramp, the gauges showed a downforce of 4.7 tons, which is over 46,000 newtons (Image 2).

The noise was intense; a child present at the presentation pressed their earbuds tightly against their ears despite being far away from the ramp. According to Lars Moravy, the fans are capable of generating up to 2 g of downforce, so we can estimate that the weight of the demonstrated version of the Tesla Roadster is up to 2.35 tons. The target weight is intended to be below 1.7 tons.

The power of the Tesla Roadster, generated by two engines driving the rear wheels, is “over 1 MW,” which equals over 1,360 horsepower, with a torque of 1,400 Nm. There are no engines in the front, and it would likely be difficult to fit one there since the cabin, battery, and radiator end near the front axle. Speaking of the battery: it is built using specially designed 4680 cells (46 mm in diameter, 80 mm in height), which are cooled from both sides to prevent the battery pack from overheating and reducing performance.

To reduce the weight of the cells and speed up heat dissipation, their casings are made of aluminum – and this seems to be the first innovation that could also be applied to Tesla Model 3 and Y. The architecture is 800-volt. The cooling system is also quite unique; the fluid flows through the battery only once, without circulation, before returning to the radiator (second innovation). Charging from 15% to 80% should take 10 minutes, which is an extraordinary achievement in the world of cylindrical cells (third).

These few minutes of downtime should be enough for 20-25-30 minutes of driving on the track.

The jet nozzles installed at the rear (Thrust version) are powered by a 200-liter tank located just behind the cockpit. It’s likely possible to borrow this from hydrogen vehicles, as the pressure seems familiar: around 70 MPa. Inside is gaseous nitrogen (other sources refer to it as “air,” which is essentially the same). The total thrust exceeds 80 kN, equivalent to that of one engine in a typical military jet. Thanks to this, the Tesla Roadster’s 0-97 km/h acceleration can take just 0.55 seconds, after accounting for rolling resistance. In Europe, it would be around 0.75 to 0.85 seconds to reach 100 km/h.

Filling the two tanks with a combined capacity of 600 liters—the Rocket version has an additional larger tank in the passenger seat area—takes 6-7 hours.

This tank holds 200 liters of fuel and is sufficient for exactly one acceleration from 0 to 97 km/h in less than 1 second. Or for up to five seconds of thrust assistance from the fuel. Refilling it takes several hours (c) Hagerty
