Weeks before Tesla was supposed to shock the world by revealing their battery-powered semi-truck, Mercedes has once again one-upped the Silicon Valley darling by beating them to the punch.  As Bloomberg points out, earlier today Daimler revealed their E-Fuso Vision One prototype, an electric semi-truck that can carry 11 tons of cargo some 220 miles before having to recharge. 

Daimler AG is jumping the gun on Tesla Inc. by showing off a battery-powered heavy-duty truck weeks before the California electric-car maker's own planned unveiling, in a sign of the growing rivalry between the companies.

The E-Fuso Vision One prototype can carry 11 tons of cargo as far as 350 kilometers (220 miles) before recharging, the world's largest maker of commercial vehicles said Wednesday in a statement. The truck, which would be geared to shorter intra-city trips, could go on sale within four years in Europe, Japan and the U.S.
