Tesla Motors, in response to a blog post that claims that Roadster batteries could fail if the car is ever totally discharged, said that this is an “irrational” concern. On Tesla’s Web site, it said that there’s a rumor started by a blogger (named Understatement) about its electric vehicles becoming a “brick” -- a totally immobile vehicle that can’t be started or pushed down the street.
Tesla said that this rumor stems from an unreasonable fear based on “limited information and a misunderstanding of Tesla's battery system." The blog said that a $40,000 battery pack replacement may be required if the car turns into a “brick.” Tesla is preparing for the start of production for its electric Model S sedan, its first wholly U.S.-built vehicle, beginning in July.
Earlier this month, Tesla had unveiled a prototype of the Model X. This is an electric crossover vehicle that will arrive in 2013. At the close Friday in New York trading, Tesla’s shares dropped by 2.3% to $33.75. So far, the shares have gained 18% this year.
David Friedman, a senior engineer for the Union of Concerned Scientists, an environmental advocacy group, said that for this to be a problem, the vehicle has to be not in use for an extended period of time.
The Tesla Roadster Sport accelerates from zero to 60 mph in just 3.7 seconds, an improvement from the 3.9 seconds of the standard Tesla Roadster. The car features a hand-wound stator and an increased winding density for higher peak torque and lower resistance. Aside from Yokohama's Ultra High-Performance tires, Roadster Sport has an improved suspension with anti-roll bars and adjustable dampers that will be tuned according to your preference.
The Tesla Roadster Sport’s price starts at $128,500 in the U.S. and at €112,000 (not including VAT) in Europe. Tesla will start deliveries for the car in late June 2009.
Michael van der Sande, Senior VP for Global Sales, Service & Marketing at Tesla, says that the Roadster Sport can beat almost anything within its price class, but it is twice as efficient as other compact hybrid sedans. According to him, the Roadster Sport is the only option for those who refuse to compromise when it comes to the environment or when it comes to performance.
Additionally, the car is the first ever derivative of the San Carlos, Calif.-based electric carmaker’s proprietary, patented powertrain. Tesla plans to start producing its all-electric, zero-emission Model S 5-passenger sedan in 2011.
So far, the company has already delivered to customers more than 150 Roadsters, and about 1,100 are on the wait list. Those who have not received delivery can upgrade to the Roadster Sport.
Tesla CEO, Chairman & Product Architect Elon Musk says that the Roadster Sport embodies the company’s spirit of continuous improvement. According to him, the Tesla Roadster has been a huge success, yet no one at the company stays contented with the status quo.
