Too good to be true? Yes, probably, but that’s what a Tesla Model S owner on Craiglist is claiming. While we will have to disagree with the owner’s definition of “minor dents and dings”, it’s not impossible to imagine how this Model S would still be able to drive – though its salvage status is evidently still well-deserved. expand full story

For the most part, Tesla’s Gigafactory has looked the same from the outside since the beginning of the year. The first phase consists of 4 sections of about 475,000 square feet for a total of 1.9 million square feet. The final version of the building, which should be completed by the end of the decade, is expected to have 13 million square feet of manufacturing and work space. It should be enough to become the biggest building on earth by footprint and Tesla plans for the factory to produce at least as much battery capacity as the entire world production of li-ion cells.
Now we learn that Tesla is planning to add a new section to the plant with an estimated completion date by the end of the year, according a building permit recently issued to Tesla. expand full story

Last year, Tesla had some troubles with the way it calculated the power output of its electric vehicles. The company had to go in mediation with over hundred of its customers in Norway and eventually changed the advertised horsepowers of the Model S P85D from 691 hp to 463 hp.
The issues mostly revolved around defining electric power in terms of horsepower and the power output being dependent on the state of charge of the battery pack feeding the car’s two electric motors. The issues have been mostly resolved after Tesla updated its advertised numbers, but since the introduction of the Model X and the ‘Ludicrous mode’, things have been more complicated again… expand full story

‘Lithium’ battery capacity degradation is one of the main concerns of electric vehicle buyers and potential buyers. Since the resurgence of electric cars is relatively recent, meaningful long-term data on large battery packs is fairly rare. Only Tesla has battery packs with a capacity higher than 30 kWh on the road in any significant number and they only have been in operation for a few years (Roadster aside).
But a few Tesla owners have accumulated impressive mileage on their vehicles and the data provides an interesting look into potential battery capacity degradation. expand full story

SolarCity published its earnings for the fourth quarter and full year 2015 yesterday. The company’s stock price fell 25% following the results, mainly because of lower than expected guidance for the first quarter 2016 and a miss in installed solar capacity following its exit from Nevada, as well as difficulties completing a few commercial projects on the east coast.
On a more positive note, we learn from the company’s SEC filing that it more than doubled its battery pack business with Tesla Energy in 2015 versus the previous year, despite the market for home energy storage only being in its infancy. expand full story

Last month we reported on comments made by BMW CEO Harald Krüger about the BMW i3 getting a new battery pack with more range in 2016. Now we learn through an article coming out of Autocar yesterday that sources close to BMW are saying that the new battery pack should enable “up to 124 miles of range on a single charge” and be available as a retrofit to current i3 owners – something Krüger hinted could be possible.
Autocar’s Greg Kable didn’t say on what he is basing his “124 miles” figure, but he compared it to the current range of the i3 which he said is “just under 100 miles”. This means he is working with the New European Driving Cycle (NEDC) which is not very accurate in predicting real world range. expand full story

Acciona, a Spanish conglomerate in renewable energy and infrastructure, created last year the first team to compete at the Dakar rally with an electric vehicle. Unfortunately, they didn’t last long, but they are coming back for Dakar 2016 and they feel more confident than ever after coming out of the Morocco Rally last month as the first team to finish it with an electric vehicle.
The company seriously upgraded the vehicle this year with a focus on efficiency and a brand new battery pack. At Dakar 2015, Acciona’s car could achieve 125 miles (200 km) on a single charge with a 140 kWh battery pack under the race’s difficult road conditions. The upgraded car has a 150 kWh pack, which is only a 7% increase, but the team says it can now travel 217 miles (350 km) on a single charge under the same racing conditions, which is a 75% increase. expand full story

Tesla builds its own battery packs, but imports the several thousands battery cells needed per pack from suppliers, mainly Panasonic. The automaker is heavily investing to change that by building the Gigafactory, in partnership with Panasonic, to manufacture both the cells and battery packs in the Nevada desert east of Reno.
But the planned output of the factory is 35 GWh in battery cells and 50 GWh in battery packs, meaning the Gigafactory will need to import 15 GWh of battery cells. Tesla already confirmed its intention to source the cells from more than one suppliers “potentially including Panasonic”, and today we learn through a new report from Asia Nikkei that the company is reportedly in the final stages of negotiations with LG Chem. expand full story

The so-called “poaching war” for top automotive engineering talent between Tesla and Apple gathered quite a few headlines in the past months, especially after Tesla CEO Elon Musk called the Cupertino company the “Tesla Graveyard” for hiring people he claimed were “fired” by the company. But after looking closer into the recent hires between the two companies, it looks like Tesla has little to fear from Apple’s recruiting effort, at least if we compare it to Faraday Future’s.
Faraday Future took a small step out of ‘stealth mode’ earlier this summer to announce that it is looking for a location for a manufacturing facility to build an electric vehicle. In the months since, the 1-year old startup ramped up its hiring effort and now has over 400 employees with an impressive percentage coming from Tesla. expand full story

As we recently mentioned, there’s been some confusion in the media about the price of the Tesla Model X. The confusion even spread to Wall Street where analysts have been reducing their target price on Tesla’s stock because of the expensive $132,000 price tag circulating in the media.
To be clear, $132,000 is the starting price of the Signature Model X which is already sold out. The Signature comes standard with the performance package (P90D) and several options which increase the price. For example, a maxed out Tesla Model S cost $138,000, but the base version starts at $70,000. Yesterday Elon Musk confirmed at a Vanity Fair conference that the Model X will have a similar price structure starting next year (when Tesla can actually catch up to demand). expand full story

Charging is still the primary concern of any new potential electric vehicle buyer. They want to know where they can charge the car and how long it takes. Now with the numerous charging standards and the difference between car models and battery pack sizes, it can be a difficult landscape to navigate. The bigger the battery pack, the longer it takes to charge, but at the same time, you can get an higher charging rate.
Netherlands-based charging station start-up Fastned is making the (safe) bet that battery packs will soon get bigger and, more importantly, they will be able to take higher charge rates. expand full story
