ZENN (Zero Emission, No Noise) is a 2-seat battery electric vehicle currently in production and built by ZENN Motor Company designed to qualify as a Neighborhood Electric Vehicle. It has a range of up to 40 miles (56 km) and does not exceed 25 mph (40 km/h). On earlier production models, there was an option of a 'Discovery Pack' which increased the ZENN's range a few miles. It now comes standard.

The vehicle is based on the Microcar (brand) MC2,in production in France since the early 2000s, and produced under license from Microcar's parent company Beneteau Group. The Microcar MC2, and the short wheelbase MC1, are sold in Europe with diesel engines.

Electric power is stored in six 12V lead-acid gel batteries, which has a recharge cycle of 8 hours. Valve regulated (low maintenance) lead-acid wet cells are available at extra cost.

Also optional are a retractable fabric sunroof, air conditioning, audio entertainment center, and AC motor, stated to be better for hill climbing. The 2008 model has a standard AC motor.

On January 16, 2007 EEStor, Inc. announced plans to ship 15 kilowatt-hour Electrical Energy Storage Units (EESU) to ZENN Motor Company by end of 2007 for use in the ZENN electric vehicles. This will make the ZENN the first production vehicle to use EESU. As of April 30 2007 ZENN Motor Company owns approximately 3.8% of the equity of capacitor developer EEstor, after an investment of $2.5M US.

Licensing agreement with EEStor

EEStor was founded in 2001 by Richard D. Weir and Carl Nelson, former senior managers in disk-storage technology at IBM and Xerox. The Company maintains a low profile, but others in the automotive and CleanTech communities are calling their storage technology ‘game changing'. Such a breakthrough has the potential to transform the energy sector and the automobile industry in particular.

The following is how the EESU will compare to other batteries used for electric cars

ZMC entered into an agreement with EEStor dated August 24, 2004 (with subsequent amendments dated November 26, 2004, September 30 2005, August 8, 2006 and January 22, 2007) to acquire in perpetuity the worldwide exclusive rights to use EEStor's EESU in the following markets:

All-electric 4-wheeled personal transportation uses for vehicles with a curb weight up to , net of the battery weight, and For golf carts and similar-styled utility vehicles, and The aftermarket conversion of any internal combustion passenger vehicle to electric drive

The EEStor Technology Agreement also provides ZMC with non-exclusive, worldwide use to manufacture higher horsepower and heavier vehicles.

City ZENN

The cityZENN is planned to be a fully certified, highway capable vehicle with a top speed of and a range of . Powered by EEStor, the cityZENN will be rechargeable in less than 5 minutes, feature operating costs 1/10th of a typical internal combustion engine vehicle and be 100% emission-free at the point of use. The Zero Emission, No Noise cityZENN will be designed to meet the transportation requirements of a large percentage of drivers worldwide. It is due to be launched in Fall 2009. Also according to Ian Clifford a normal household outlet with 110 volt supply can fully charge the EESTor powered CityZENN in 4 hours for a range and a normal household outlet with 220 volt supply can fully charge the EESTor powered CityZENN in 2 hours for a range. CityZENN target price is around $25000 - $30000.
