The?Tesla?Roadster is receiving battery power upgrade which will allow the performance car to get nearly even more far without recharging.
“There’s a simple couple of speeds and driving conditions where we’re able to confidently drive the Roadster 3.0 over 400 miles,” Tesla said inside a statement.
The Tesla Roadster 3.0 package involves three main improvement areas:
Batteries: The Roadster battery was the initial lithium ion battery used in production in any vehicle. It was cutting edge in 2008, but cell technologies have improved substantially after that. Tesla claimed it has identified a fresh cell who has 31% more energy compared to original Roadster cell. By using this new cell Tesla has created a battery pack which offers roughly 70kWh inside the same package as being the original battery.
Aerodynamics: The main Roadster were built with a drag coefficient (Cd) of 0.36. Using modern computational methods Tesla plan to develop a 15% improvement, dropping the entire Cd down to 0.31 which has a retrofit aero kit.
Rolling Resistance: The initial Roadster tires possess a rolling resistance coefficient (Crr) of 11.0 kg/ton. New tires for the Roadster 3.0 contain a Crr of roughly 8.9 kg/ton, regarding a 20% improvement. Tesla can also be making improvements within the wheel bearings and residual brake drag that further reduce overall rolling resistance with the car.
Tesla expects the mix of them improvements to supply a 40-50% improvement on range between the main Roadster and Roadster 3.0. There’s a simple number of speeds and driving conditions this agreement Tesla says it could confidently drive the Roadster 3.0 greater than 400 miles.
Tesla shows the enhanced range for the new Roadster in the drive from Bay area to New york in the early weeks of 2015.
Tesla also said no new Model S battery or major range upgrade is anticipated in the near term.
