Colorado-based electric vehicle manufacturer Boulder Electric Vehicle recently delivered a truck to its very first paying customer—a local plumbing company. The truck, named the DV 500, is an electric delivery truck that the company has had in development for 18 months.

Boulder’s truck is not cheap, coming in at about $70,000, but the company says one of their models only costs seven cents a mile to operate. Taking into account maintenance, fuel costs and vehicle life, that could save a business owner about $5,000 to $8,000 dollars per year, per truck.

So just what will a Boulder customer get for the money? The Boulder is powered by a lithium-ion phosphate battery that spins an AC motor. That combo provides customers with a top speed of 65 mph and the choice of a truck capable of 40, 80 or 100 miles of range, depending on battery selection.

The truck’s 21-foot-long chassis is composed of a lightweight aluminum composite while the body is made up of a rust-proof unibody composite. Inside there is 4,000 pounds of payload capacity and 864 cubic feet of cargo space. And for a delivery truck, the Boulder has some surprising features, including inside LED lighting, a built-in tire pressure monitoring system, electric-assisted power steering, forced air heating and cooling in the cab as well as a side entrance into the cab, which makes for a safer environment for the delivery driver.

Even though the Boulder looks a bit retro from the outside, the company says they have invested heavily in the truck’s aerodynamics to provide efficiency and aid stability in gusty conditions. To that end, the truck also features easily replaceable flat glass windshields.
