The E301 was designed by ESORO in early 1991 and presented at the 1993 Geneva Motor Show. With its well-balanced overall concept, a wealth of technical innovations and a convincing design, it caused a sensation and set a new standard for efficient lightweight electric-driven cars but also for compact vehicles in general. Its drag coefficient of 0.195 is, even today, an absolute record value for a four-seater vehicle and its consumption of 9 kWh/100 km from the mains means that the E301 is still the record holder in its category. Safety, efficiency and comfort were combined for the first time with lightweight construction, a modular bodyshell concept and an open system for three different drive concepts - electric, hybrid and small IC-engine.

A self-supporting safety passenger cell, contrasted in a light or dark colour and consisting of only a few parts, formed the structure of the vehicle. The panelling, window and tinted plastic bodyshell components allow maximum flexibility. Design copyright was applied for in 1992 for this concept. Different of today's cars feature this concept in modified form.

The self-supporting composite bodyshell allows modular modifications to the rear body sections without major effort: the ESORO E301 can be designed as required as a coupé, high-back, mini pick-up or convertible. The arch of the safety passenger cell made of plastic and which is emphasised intentionally in this design ensures a high recognition value for the marque.
One other innovation of the E301 is its semicircular, patented swivel windows and double-hinged doors.
