Note: Tesla Motors has strictly announced a new battery. See a sum below.
Electric vehicles currently don’t magnitude adult to gas-powered cars and trucks on copiousness of counts—but a largest emanate holding behind a electric-car marketplace is a operation offering between charges. Going on a highway trip? Better make certain there are charging stations each 200 miles or so.
On Friday, Tesla Motors is approaching to announce that a new epoch is here for electric vehicles—with a new battery container that offers a 400-mile operation between charges. That’s a longer strech than many gas vehicles (though it still can’t hold a operation of diesel cars like a Volkswagen Passat driven 1,600 miles on a tank of gas, behind in 2012).
To start, a new battery container will be offering for a Tesla Roadster (Tesla’s strange vehicle), CEO Elon Musk tweeted on Christmas. They’re set to eventually make their approach into other Tesla electric vehicles.
Roadster ascent will capacitate uninterrupted transport from LA to SF — roughly 400 mile range. Details tmrw. Merry Christmas!

The battery-pack ascent Musk mentioned is expected to meant battery deputy for 2,400 existent Roadsters on a highway today–although those sum aren’t nonetheless transparent clear. In any event, longer-range batteries are eventually designed for a flagship Model S, that now takes drivers 265 miles on a charge.
Should discuss that a battery container ascent is not entrance shortly for a Model S, though it apparently *will* occur long-term.

If Tesla vehicles unequivocally do get 400-mile operation out of a new battery, this would be a really large impulse for electric vehicles.
Update: Tesla only put out a official announcement, observant that a association has detected a new form of battery dungeon record and done other improvements to a Roadster.
If a speeds and pushing conditions are right, “we can quietly expostulate a Roadster 3.0 over 400 miles,” Tesla said. “We will be demonstrating this in a genuine universe during a uninterrupted expostulate from San Francisco to Los Angeles in a early weeks of 2015.”
The proclamation doesn’t contend privately when or how a new batteries will be done accessible as upgrades for existent Roadsters.
Here’s a full announcement:
Battery record has continued a solid alleviation in new years, as has a knowledge in optimizing sum automobile efficiency. We have prolonged been vehement to request a training behind to a initial vehicle, and are anxious to do only that with a antecedent Roadster 3.0 package. It consists of 3 categorical alleviation areas.
The strange Roadster battery was a really initial lithium ion battery put into prolongation in any vehicle. It was state of a art in 2008, though dungeon record has softened almost given then. We have identified a new dungeon that has 31% some-more appetite than a strange Roadster cell. Using this new dungeon we have combined a battery container that delivers roughly 70kWh in a same package as a strange battery.
The strange Roadster had a drag fellow (Cd) of 0.36. Using complicated computational methods we design to make a 15% improvement, dropping a sum Cd down to 0.31 with a retrofit aero kit.
3. Rolling Resistance
The strange Roadster tires have a rolling insurgency fellow (Crr) of 11.0 kg/ton. New tires that we will use on a Roadster 3.0 have a Crr of roughly 8.9 kg/ton, about a 20% improvement. We are also creation improvements in a circle orientation and residual stop drag that serve revoke altogether rolling insurgency of a car.
Combining all of these improvements we can grasp a likely 40-50% alleviation on operation between a strange Roadster and Roadster 3.0. There is a set of speeds and pushing conditions where we can quietly expostulate a Roadster 3.0 over 400 miles. We will be demonstrating this in a genuine universe during a uninterrupted expostulate from San Francisco to Los Angeles in a early weeks of 2015.
We are assured that this will not be a final refurbish a Roadster will accept in a many years to come.
