Tesla Motors Announces Version 3.0 Of Its Electric Roadster Model With A Range Of 650 Kilometers
|   Sunday, January 11, 2015
With an advertised autonomy of 650 kilometers (400 miles), the new version of the electric two-seater convertible from Tesla will allow holders to travel long distances close to those reached by gasoline powered models.

The Tesla Roadster, the first model produced by the American manufacturer of pure electric models, Tesla Motors, has received substantial improvements in the technological level, the most important of which is linked to the traveled range allowed by the batteries that power the electric motor.


According to a press release announced by Elon Musk, chief executive, the 3.0 version Tesla Roadster offers its owners the opportunity to run no less than 640 kilometers between recharges. This is the best performance provided by an electric car in 2014 and the absolute record for Tesla Motors.

According to the American company, technological developments in recent years make the Tesla Roadster, a model released in 2008 and based on the Lotus Elise's chassis, to benefit from a 30 percent increased autonomy compared to its predecessor, a model which people at Tesla phased out of the range three years ago.

This happened to concentrate sales on the Model S sedan which raised the Californian brand from being a promising brand to being a global manufacturer. At this time, Tesla has factories on two continents and showrooms in the most important cities around the world. Now, the increased range for Tesla's Roadster is about 55 percent compared with the previous generation, thanks to further improvements in the aerodynamic kit, new tires, and an improved set of brakes.

So, to summarize, the Roadster 3.0 package is made of 3 main areas:
Batteries: a new cell was discovered which holds 31 percent more energy than the initial cell Roadster. The lithium-ion battery which was equipped initially on the Roadster was the first battery to go into production. It was the best in 2008. But since then cell technology has improved substantially. Using this new cell a battery was made that provides approximately 70 kW within the same casing as the original battery.

Aerodynamics: Thanks to modern calculation methods we will see an improvement of 15 percent. The drag coefficient (Cd) will reach 0.31 with an aero rehabilitation kit. This drop is remarkable, seeing that the first Roadster had a Cd of 0.36.

Rolling Resistance: New tires have a rolling resistance coefficient (CRR) of about 8.9 kg / ton, a 20 percent improvement over the original Roadster, which saw tires with a CRR of 11.0 kg / ton. Improvements in wheel bearings were also made which further reduces overall rolling resistance of the car.

Tesla Motors announced it will demonstrate the abilities of the improved version in a test. This test will be carried out on the west coast of the United States. A car will have to cover the distance between Los Angeles and San Francisco (650 kilometers) without recharging along the way. The test will take place in early 2015.
According to statements made by Elon Musk, the Model S will also benefit from an improved battery, but this is "not going to happen very soon."
