Heres how Chevrolet built a practical electric vehicle with the 2017 Bolt EV

Chevrolet said it was going to bring an affordable, long-range electric vehicle to market and it did, with the 2017 Bolt EV. I visited Palo Alto to find out more about the Bolt EV, and the techbehind it, speaking to the cars lead engineers and designers.

The Bolt itself was present, too, of course,an impressive car currently shipping to customers that offersan equally impressive drive (more on that in a forthcoming post). Also strangely present in absentia was Tesla, which is the company that has yet to make good on a similar promise to deliver affordability and range in an EV package.

Chevrolet was quick to point out than in Canada at least, its outselling Tesla two to one when it comes to electrified vehicles, before the Volt has even launched. Thats if you count theVolt, Chevys hybrid electric with a 53-mile pure electric range and gas-powered extend range of 420 miles total. We are the leader in the electrification of vehicles, a spokesperson told a room of journalists at the Bolt first drive event.

The Bolt EV does feel like a vehicle capable of leading the industry; the cars 238-mile range from its 60 kWh battery is better than the 210 mile EPA rating on Teslas 60 kWh Model S(though the 75, 90 and 100 kWh options all offer better estimates than the Bolt), and it costs less than half the price of the lowest-specced Tesla. So how did Chevrolet get here?

The Bolt EV is the product of a lengthy design process that involved Chevrolet rethinking car construction and power supply from the ground up, according to Bolt Vehicle ChiefEngineer Mike Lelli. Hewalked us through the cars use of materials, which balances structural rigidity where it needs it most, with flexibility and weight savings where it can afford it, to help maximize interior space without compromising onbattery mileage.

That battery is also uniquely designed, with continuous rectilinear shape that undergirds the vehicle, making it possible to have a low, flat continues floor throughout the car while distributing battery weight evenly and helping create a low center of gravity.

Lelli says that all the hard word that went into designing the Bolt EV as a vehicle tailor-made for balancing range and comfort has paid off, and the evidence is the shipping car itself, which manages to sneak under the $30,000 threshold in the U.S. with incentives (and only just exceeds $30,000 in my home province of Ontario after credits andincentives).

The motor, too, is an exercise in elegant simplicity. It actually only has one physically engaged gear, so to speak: Park. Theres a latch that will ensure it cant move when in park, but otherwise speed is adjusted by changing the rotational velocity of the axle within the motor.

Heres the thing: Chevrolet has succeeded at its initial goal, but the Bolt EV is still going to face a big test in terms of its ability to appeal to general consumers. Other automakers will be watching closely to see if the Bolt does well, and thatll inform their own decisions to pursue a similar path twitch models of their own. GM, too, will likely change its strategy regarding EVs considerably depending on the outcome of the bolt.

Leaving aside the tech within, and the stakes, however,Bolt is also just a fun car to drive: Stay tuned for a deeper drive into how it performs in practice coming up shortly on TechCrunch.
