Mack is ready to attack the electric truck segment.

The Volvo-owned automaker has announced its first all-electric medium duty model at The Work Truck Show in Indianapolis.

The Mack MD Electric is a 4x2 straight job that will be offered in five chassis lengths in Class 6 and Class 7 configurations.

It will be available with either two or three 240 kWh battery packs that will provide 150 miles or 230 miles of range, respectively.

"Mack established itself as an electrification leader with the heavy-duty Mack LR Electric refuse vehicle, and we're excited to add the MD Electric to our zero-tailpipe emissions lineup," said Martin Weissburg, global president of Mack Trucks. "This is another important step in our efforts to drive decarbonization and a more sustainable future, and we plan to continue investing in technologies that help improve the environment and society."
