Terraline, a California-based company formerly known as Solo Advanced Vehicle Technologies (Solo AVT), has announced the Tangra LH1, a human-operated battery-electric Class 8 truck that the company says will have over 500 miles of range. The company had been working on autonomous technologies, but the newly-named company says the LH1 is designed with human drivers in mind. Terraline plans to deploy test vehicles with customers this year.
