Tesla Model S renews the range: more power, more autonomy, less … – International Business Times Italian

You can not really say that Tesla is among the companies in the automotive industry, among the most stingy of news: CEO Elon Musk announced three major developments for the car range California electric company , and although once again (betraying the expectations) was not told anything regarding the Model X and Model 3, what has been revealed is more than enough to capture ‘ attention.

First, The Model S70 is now the “entry level” of the range with a reduced price of $ 5,000 : to buy the sedan US are now required “just “$ 70,000, which could further decrease due to sales incentives available in many countries. “In addition, not having to buy gasoline and as an electric car has isogno less maintenance, there is a savings of about $ 2,000 per year, or $ 10,000 less than the national average for car ownership in a period of five years, “says Musk.

The Tesla Model S70 rear-wheel drive has a 332 horsepower engine, is able to sprint from 0 to 60 miles per hour (or by 96 km / h) in 5.2 seconds, and has a respectable range of about 370 km before needing to be recharged , free of charge, in one of the Supercharger made available by Hawthorne.

Just looking at the battery, Tesla has also thought of those who own or want to buy a Tesla and want to get as far away: this is now possible thanks to upgrade the battery pack, which went from 85 to 90 kWh : this means roughly 6% of battery life in addition, that on the highway at a speed of 105 km / h will travel up to 483 km. The upgrade is available for both new customers and for those already in a garage 85D (which compared to the S70 is equipped with all-wheel drive), although for the latter Musk suggests buying the refurbished battery pack only if their normal profile Usage touches already the maximum range.

One of the most interesting technological developments in the Tesla range is related to performance, increased thanks to a new fuse “smart” batteries for electric cars of ‘US company : “Instead of a standard fuse that simply melts once past a certain amperage, which requires a big gap between the normal operating current and the maximum, we have developed a fuse with its electronics and a small battery lithium-ion battery, “says Musk. “The current is constantly monitored at the level of milliseconds, and is pyro-activated to cut the energy with extreme precision and security.”

This has allowed us to increase the amperage from 1,300 to 1,500 amperes, and in this way were also increased performance : an acceleration from 0 to 96 km / h in 2.8 seconds, a time on the quarter mile (402 meters) 10.9 seconds and a top speed of 250 km / h. The incredible acceleration was described as “Ludicrous Mode” (“Absurd mode”), and is even higher than what Tesla had already begun offering in recent months with the “Insane Mode” (“Insane Mode”).

Try the satisfaction of acceleration from supercar (just to give you a comparison: we are at the level of a McLaren P1) it will not be cheap: the new battery fuses with “smart” will cost $ 10,000 for new customers, while those who already own a P85D will pay only $ 5,000 plus installation costs.
