Can Gas Vehicles Survive Elon Musk’s Next Announcement?

Tesla Roadster.

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.

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.

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.

 

1. Batteries
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.

 

2. Aerodynamics
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.

 

Summary
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.
