Lightning eMotors introduces new generation 4 Lightning Electric Transit Class 3 Van; battery-electric and fuel cell electric variants Lightning eMotors has announced a new model of its Class 3 Lightning Electric Transit Van. The new, longer-range Lightning Electric Transit Van is the fourth generation of its battery-electric and fuel cell electric platform, based on the Ford Transit 350HD chassis. The Gen 4 powertrain, with new battery technology and up to 105 kWh of battery capacity, has up to 40% more range than the Gen 3’s 120-mile range as a battery-only vehicle, with fuel cell configurations extending the range to 250 miles (based on EPA-certified dynamometer testing) and new pricing that provides a compelling total cost of ownership versus a gasoline van.
