Chevrolet Performance K5 Blazer-E Powertrain Intro


At SEMA360, Chevrolet showed off its latest electric vehicle: a 1977 K5 Blazer. It was, of course, a conversion. The all-electric K5 Blazer-E is their functional proof of concept of the upcoming Electric Connect and Cruise package Chevrolet Performance plans to sell in the second half of 2021.

Chevrolet showcased a 1977 K5 Blazer converted to all-electric propulsion at SEMA360. The new K5 Blazer-E retains as much of the stock Blazer as possible and approximately 90 percent of the new parts installed for the eCrate package are factory components from the Chevrolet Bolt EV.

Building the K5 Blazer-E

Before the Blazer could show off its new upgrade, the old 175-horsepower 400 cubic-inch V-8, three-speed automatic, fuel system, and exhaust had to go. That made room for the new Bolt EV electric motor, delivering 200 horsepower and 266 lb-ft of torque. It’s 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.

The aftermarket components include an electric power steering kit, an electric pump providing vacuum to the stock brake system, and an electronic controller to drive inputs to the vintage Blazer gauges – such as displaying the battery’s state of charge on the original fuel gauge.

To prepare for the eCrate launch, Chevrolet Performance is certifying Electric Connect and Cruise installers. Participating Chevrolet dealers and aftermarket companies will receive the training, tools, and equipment needed to work with high-voltage systems and charging stations to service customers’ vehicles.
