It has been a long journey, but it looks like the Tesla Model S all-electric sport sedan is one step closer to series production as the California-based automaker announced it is moving on to the final road tests. The first phase called Alpha, which began in 2010, includes both computer simulations and test-drives of prototype vehicles. There will be a Beta phase as well.
�The first Alpha is amazingly agile for a car of its size. It has great handling balance and poised ride with communicative steering. Just goes to show what combining a low center of gravity with a very stiff body structure can achieve�, said test drive Graham Sutherland.
According to Tesla, Alpha cars will be tested in the coming months in all sorts of climatic conditions, which should help engineers improve the EV�s driving dynamics.
Tesla�s second model after the Roadster offers seating for five adults and two children. The Model-S' drivetrain consists of an electric motor coupled to a single-speed transmission and a floor-mounted lithium-ion battery pack. Customers will be able to specify their cars with one of three available battery packs offering a driving range of up to 160, 230 or 300 miles (258, 370 or 483 kilometers).
Roughly the same size as a BMW 5-Series, the Model S sprints to 60 mph (96 km/h) in 5.6 seconds and can reach a top speed of 130 mph (209 km/h). Production is set to begin in 2012 and Tesla is currently taking orders, with the base price set at US$49,000, including a US$7,500 Federal tax credit.
