The Tesla Roadster has seen significant improvements in reducing drag, which helps it move more efficiently through the air. For the Roadster 3.0, Tesla aimed to lower the drag coefficient (Cd) by about 15%, from 0.36 to around 0.31, using modern computational methods and a retrofit aero kit 🚀. This reduction in drag helps the car use less energy, allowing it to travel further on a single charge.
The original Roadster had a range of about 245 miles, but with these improvements, the Roadster 3.0 can travel over 400 miles 🚗. This is a big increase, showing how important aerodynamics are for electric vehicles. By making the car more aerodynamic, Tesla was able to make it more efficient and capable of longer trips without needing to recharge.
In addition to aerodynamics, Tesla also improved the rolling resistance of the tires, which helps the car move more smoothly on the road 🛣️. This, combined with better aerodynamics, makes the Roadster 3.0 a more efficient and powerful vehicle.
The new Tesla Roadster, announced more recently, takes this efficiency even further with its sleek design and advanced technology, allowing it to achieve a range of up to 620 miles 🌟. This shows how much Tesla has learned about making cars efficient and powerful over the years.
