The cooling and battery management system keeps the temperatures and voltages within specific limits. A full recharge to 53 kWh requires about 3 + 1 ⁄ 2 hours using the "High Power Wall Connector", which supplies 70-amp, 240-volt electricity. Tesla said in February 2009 that

1650-522: The ESS had expected life span of seven years/100,000 mi (160,000 km), and began selling pre-purchase battery replacements for about one third of the battery's price today, with the replacement to be delivered after seven years. Tesla says the ESS retains 70% capacity after five years and 50,000 mi (80,000 km) of driving, assuming 10,000 mi (16,000 km) driven each year. A July 2013 study found that after 100,000 mi (160,000 km), Roadster batteries still had 80%–85% capacity and

1716-611: The Lotus Elise as a base for the Roadster was a poor strategy because the Elise was incompatible with the intended AC Propulsion technology and was modified so extensively only 7% of the Elise remained in common with the final production Roadster. Tesla's cumulative production of the Roadster reached 1,000 cars in January 2010. The Roadster is considered an American car though many carry a Vehicle Identification Number beginning with

1782-514: The Roadster Sport, the first derivative of Tesla's proprietary, patented powertrain. The car accelerates from 0 to 60 mph (0 to 97 km/h) in 3.7 seconds, compared to 3.9 seconds for the standard Roadster. Changes for the 2010 model-year cars included: All of these features, except for the motor, were available either as standard or as add-on option for the non-sport model. Beginning mid-March 2010, Tesla, in an effort to show off

1848-461: The Roadster in January 2012. Subsequent to completion of the first production car, the company announced problems with transmission reliability. The development transmission, with first gear enabled to accelerate 0 to 60 mph (0 to 97 km/h) in 4 seconds, was reported to have a life expectancy of as low as only a few thousand miles. Tesla's first two transmission suppliers were unable to produce transmissions, in quantity, that could withstand

1914-771: The Roadster one of the least expensive cars with an entirely carbon fiber skin. Several prototypes of the Tesla Roadster were produced from 2004 through 2007. Initial studies were done in two development mule vehicles based on Lotus Elises equipped with all-electric drive systems. Tesla then built and tested ten engineering prototypes (EP1 through EP10) in late 2006 and early 2007, which led to many minor changes. Next, Tesla produced at least 26 validation prototypes, which were delivered beginning in March 2007. These final revisions were endurance and crash tested in preparation for series production. In August 2007, Martin Eberhard

1980-481: The Roadster's battery-to-wheel efficiency as 110 Wh/km (17.7 kWh/100 mi) on an unspecified driving cycle—either a constant 60 mph (97 km/h)) or SAE J1634 test—and stated a charging efficiency of 86% for an overall plug-to-wheel efficiency of 128 Wh/km (20.5 kWh/100 mi). In March 2007, Tesla reported the Roadster's efficiency on the EPA highway cycle as "135 mpg [U.S.] equivalent, per

2046-451: The acceleration from 0 to 60 mph (0 to 97 km/h) in under 4 seconds and an improved motor limit of 14,000 rpm to retain the 125 mph (201 km/h) top speed. In the interior the gear selector is similar to a push-button automatic with buttons labeled P, R, N and D. Some earlier models have a gear lever similar to that in cars with manual transmission. The Roadster's 0 to 60 mph (0 to 97 km/h) acceleration time
