Unveiled at last year's Frankfurt Motor Show, the Mercedes-Benz Concept B-Class E-Cell Plus was meant to be a preview of the German automaker's first range-extended electric vehicle. Along with a battery pack to power it for 100 kilometers (62 miles), it was also to feature a 1.0-liter three-cylinder turbocharged gasoline-burning engine to give it an additional 400 kilometers (248.5 miles). Indeed, a production version was to be shown this past April at the New York Auto Show.
Reports of Mercedes-Benz and Tesla building an electric A-Class together are nothing new. In fact, a fleet of 500 A-Class-based E-Cells was built for Europe. Most recently, a Tesla earnings report revealed that Tesla was still working on an all-electric powertrain for an unnamed EV for Daimler, the evolution of a deal that began when Daimler invested in the Silicon Valley automaker in 2009. The two automakers also worked together on the Smart ED.
