Chevrolet plans on showcasing a 1977 K5 Blazer converted over to all-electric propulsion for SEMA360, foreshadowing the Electric Connect and Cruise package General Motors hopes on selling in the latter of 2021. But it would first like to take the public’s temperature on the concept by surveying SEMA attendees interested in building their own electric projects before finalizing its “eCrate” offering.

That makes the modified Chevrolet Blazer-E a proof of concept to help customers realize what kind of projects might be possible and get the creative juices flowing — something which never seems to carry over when it comes to naming EVs.

GM has been doing the electric conversion concepts for a while now and noted that the 2018 Chevrolet eCOPO Camaro and 2019 E-10 pickup helped the manufacturer decide how best to tackle its Blazer project. Chevy decided to keep as much of the SUV stock and attempted to make any swapped components hassle-free, adding that 90 percent of the new parts installed for the eCrate package came directly factory components used on the Chevrolet Bolt.

From GM:

To convert the 1977 K5 Blazer, the team first removed from the Blazer the original 175-horsepower 400 cubic-inch V-8, three-speed automatic, fuel system and exhaust. Then, the team installed a Bolt EV electric motor, delivering 200 horsepower and 266 lb-ft of torque, paired with a Chevrolet Performance electronically controlled four-speed automatic. The rest of the Blazer drivetrain remains untouched, including the transfer case, driveshaft and axles.

Power is supplied by a 400-volt Bolt EV battery pack with 60 kilowatt-hours of usable energy installed in the cargo area. Using production controllers and wiring harnesses preserves many Bolt EV features, including shock protection, battery heating and cooling, battery-overcharge protection and even regenerative braking.

Excuse the editorializing, but this is exactly the kind of thing that had me geeked about EVs in the first place. Most electrically powered vehicles haven’t spoken to me (with a handful of exceptions). But the possibility of installing an e-powertrain into a vintage and otherwise-normal-looking automobile is genuinely intriguing. Imagine chucking a pair of torque-rich electric motors into a 1992 Mitsubishi Mirage and living in a sleeper’s paradise.

It’s easy to see where Chevy’s going with this and it’s nice to see them keeping things simple, even if it probably had a lot to do with the pandemic keeping everyone away from whatever garage they used to piece the Blazer-E (again, awful name) together.

Additional aftermarket components are said to include an electric power steering kit, electric pump providing vacuum to the stock brake system, and an electronic controller to drive inputs to the vintage Blazer gauges (allowing the original fuel meter to display the SUV’s current state of charge). Understated and slick but it’s all in service of Chevrolet Performance hawking the eCrate.

As of now, the plan involves certifying as many service centers and aftermarket companies to install the system and selling them the necessary tools. Afterward, they’ll be eligible to install the initial eCrate offering — which includes a 60-kWh battery pack, 200-hp electric motor, wiring harnesses, cooling pumps, and the obligatory DC-to-AC power inverter and converter.

Assuming it’s a success, Chevy said it would entertain the possibility of a “wider range of aftermarket applications” that included high-performance applications and larger battery packs.

SEMA has gone virtual this year to keep people from coughing near each other. But GM said customers could follow all the action on the Chevrolet Performance YouTube page, which currently features a glut of electric conversions and LS swaps.
