Tesla Roadster 3.0 package prototype announced with 400-mile possibilities

Once a car company ceases to manufacture a particular model, it is relegated to history, largely forgotten by its maker. Sure, warranties are honored and recall-worthy items are (hopefully) taken responsibility for, but post-production improvements are left up owners and the aftermarket. With the announcement of the Roadster 3.0 package, Tesla once again reminds us it is not most car companies. Following a heads-up given by CEO Elon Musk last week on Twitter, the company has now shared some details of a new upgrade it will be making available for its electric sports coupe sometime in 2015. For a yet-to-be-disclosed price, owners can opt to have their cars upgraded with a 70-kWh battery, some aerodynamically-optimized body bits and low-rolling resistance tires. Together, the enhancements should offer a 40-50 percent range improvement and give Roadsters a 400-mile range under certain conditions. Originally, it came with a 56-kWh unit and was rated for 245 miles on a charge. Tesla tells us that "this is a retrofit package currently in its prototype phase", and so it still isn't clear whether the changes will allow Roadsters to be compatible with the Supercharger network, or whether the body kit will affect the outward appearance. We do know that this automotive augmentation does not also apply to the Model S, though it does give hope that those cars will also be on the receiving end of similar upgrades in the future. The California company plans to put its 3.0 package to the test sometime early in the new year, with a road trip from San Francisco to Los Angeles. Interestingly, it says that this will not be the last time it offers improvements for its original model. You can get more details on the update below. Roadster 3.0 The Roadster 3.0 package applies what we've learned in Model S to Roadster. No new Model S battery pack or major range upgrade is expected in the near term. Battery technology has continued a steady improvement in recent years, as has our experience in optimizing total vehicle efficiency through Model S development. We have long been excited to apply our learning back to our first vehicle, and are thrilled to do just that with the prototype Roadster 3.0 package. It consists of three main improvement areas. 1. Batteries The original Roadster battery was the very first lithium ion battery put into production in any vehicle. It was state of the art in 2008, but cell technology has improved substantially since then.

How four states are trying to woo Tesla Motors' gigafactory

And they're off! Arizona, Nevada, New Mexico and Texas are all in the running for Tesla Motors' gigafactory, USA Today says. And the politicians are already talking big, which is the operative word for a factory that could cost $5 billion, require 1,000 acres, take up 10 million square feet and support 6,500 jobs. Oh, and build battery packs for a half-million EVs a year. New Mexico Gov. Susana Martinez earlier this week said the state was considering a special legislative session to work up an economic package for a possible Tesla factory. The governor is playing up how the state recently cut corporate tax rates and says New Mexico's in talks with the electric-vehicle maker, though she's hush-hush about the details, the Albuquerque Journal says. Meanwhile, Arizona this week proposed a bill that would allow Tesla (which has a showroom in Scottsdale) to sell its vehicles in the state without a third-party dealership network. There are politicians claiming such a law wouldn't be a carrot of sorts to lure the company's new battery plant, according to AZ Central, to which we say "yeah, sure." The bill, which would need Arizona Senate approval, would put the state diametrically opposite Texas, which has been the most steadfast about retaining the age-old third-party dealer system that Tesla's been trying to subvert. Taking it one step further, Tucson Mayor Jonathan Rothschild said the city has identified a suitable site and is willing to pony up tax incentives over and above what the state will offer, according to the Arizona Daily Star. And Nevada? Well, it has Vegas. Of course, Tesla itself has encouraged a bit of March Madness-style guesswork by posting a forum on its website in which readers and writers can hypothesize on where the factory will end up. Stay tuned.

Panasonic has an idea to be Tesla's one and only gigafactory partner

Samsung? Who's Samsung? That's what Panasonic is asking as the electronics conglomerate makes it clear it is looking to secure its position in Tesla Motors' plans to build a huge car-battery factory over the next three years. Panasonic is now saying it expects to be the only battery manufacturer partner for Tesla's so-called gigafactory, Reuters says, citing comments from Panasonic senior executive Yoshio Ito. Ito says his company has been in talks with Tesla about its construction plans, and while Samsung started supplying Tesla's batteries last year, Panasonic, which makes Tesla's lithium-ion cells, is looking for solo billing once the $5-billion factory goes live in 2017. All Tesla CEO Elon Musk has said so far is that he expects Panasonic to be the main partner in the gigafactory. Tesla, when contacted by AutoblogGreen, declined to comment on Ito's comments. Last fall, Panasonic and Tesla reached an agreement in which Panasonic would increase its supply of battery cells to Tesla by a factor of 10 within the next three years, and Panasonic says its already doubled its battery-production investment this year largely because of the California automaker. That said, Panasonic president Kazuhiro Tsuga said in March that there was significant risk involved in any investment in the gigafactory and hadn't committed to any investment as of that time. So Ito's comments may merely be a negotiation ploy. Tesla is looking for partners to shoulder about $3 billion of the $5 billion gigafactory cost. Earlier this month, Lux Research estimated that Panasonic has a 39-percent global market share for plug-in and hybrid batteries. NEC has 27 percent and LG Chem has nine percent.
