Torrance, Calif.-based Enova Systems Inc. delivered four incremental 120kW drive systems to U.K.-based Optare Plc for integration into their Solo Electric Bus. Optare has chosen Enova as the production drive system supplier for their all-electric buses.

Optare designs, manufactures and sells single deck and double deck buses and mini coaches. Its buses operate in the UK, Continental Europe and North America.

Based on the award-winning Solo low-floor bus, of which over 4,000 are in service worldwide, the Solo EV produces zero tailpipe emissions. The model is based on a standard 27-seat Solo, but the technology can be used on other models in the Optare range with higher passenger capacities. The Solo EV has been designed to perform exactly like a standard diesel-powered bus, except that it is smoother, quieter and cleaner. It is completely traffic compatible, with good acceleration and hill climbing capabilities.

Commuters and bus passengers across England will see more eco-friendly buses on the roads, congestion reduced and services upgraded, thanks to a new multi-million dollar package of improvements approved by Local Transport Minister Norman Baker. Five bus manufacturers will benefit from orders for their eco-friendly hybrid, electric and gas buses, including Volvo, Wrightbus, Optare, MAN and Alexander Dennis Ltd.
