In late January, DailyTech brought you news that Telsa would end the production of its current all-electric Roadster in 2011. The information regarding this development was found within the company's SEC filing for an IPO. The company explained that sales would stop "due to planned tooling changes at a supplier for the Tesla Roadster."

The company then added, "we do not currently plan to begin selling our next generation Tesla Roadster until at least one year after the launch of the Model S, which is not expected to be in production until 2012."

It now appears that Tesla Motors is changing its tune and has made arrangements for its suppliers to continue providing parts for the Roadster through 2012 according to Autoblog.

"Responding to customer demand, Tesla has negotiated agreements with key suppliers that will increase total Roadster production by 40% and extend sales into 2012," said Telsa in a company newsletter.

It's quite interesting that Tesla was able to not only get production extended, but also a boost in production as well for the Roadster. There must have been some serious negations going on to get its suppliers to go from "we're cutting you loose" to "sure, we'll make room for 40 percent more capacity" in just over a month.

By extending the sales of the Roadster into 2012, that gives Tesla time to bring its four door Model S sedan to the market during the same year without having a lull in vehicle sales. According to Tesla's SEC filing, the next generation Roadster will debut in 2013.
