Lightning eMotors announced that Lightning customer ACE Parking’s San Diego Airport fleet of ZEV4 and ZEV5 shuttle buses has surpassed one million all-electric, zero-emission miles, according to the company's news release.

“ACE Parking’s San Diego Airport fleet is a success story not just for Lightning, but for fleet vehicle electrification, and it’s been an honor to be ACE’s chosen partner in this important deployment,” said Kash Sethi, Lightning CRO. “It’s always such a point of pride — and a testament to our shared commitment to providing clean, safe, and sustainable transportation — to see one of our fleets pass the one-million-mile mark. We’re looking forward to many more miles with ACE.”

Lightning delivered 16 Class 4 ZEV4 and 8 Class 5 ZEV5 electric shuttle buses to ACE Parking in 2020. Since deployment, the fleet has transported more than 1.5 million passengers over one million miles and mitigated over 1,050 tons of CO2 emissions from the atmosphere. The fleet is supported by Lightning Insights, Lightning’s EV-specific telematics service that monitors vehicle location, efficiency, charge status, and more in real time.

The ZEV4 and ZEV5 zero-emission shuttle buses have averaged 41.1 and 34.4 MPGe.

“Lightning has been a good partner for us, providing strong service and support throughout the deployment despite ongoing gen1-technology hurdles,” said Steve Burton, president of ACE Parking. “We’re very happy with the environmental benefits of our Lightning fleet, while our drivers and passengers enjoy the quiet, refined performance only an EV can deliver.”

Lightning is now delivering the third generation of its ZEV4 shuttle bus with additional benefits, such as the batteries fully contained between the frame rails, redundant parking brake, push-button shifting, and more.

The ACE Parking vehicles participated in the California Air Resources Board’s (CARB) Hybrid and Zero Emission Truck and Bus Voucher Incentive Project (HVIP).
