The Myers Motors NmG (formerly the Corbin Sparrow) was a single-passenger, three-wheeled, battery electric vehicle designed specifically for commuting and city driving, produced from 1999 into the early 2010s. It was initially produced by Corbin Motors, and subsequently after 2005, by Myers Motors. It is a personal electric vehicle (PEV).
The Sparrow is powered by a 20 kW (continuous) 156-volt DC or 3-phase AC electric motor and has a range of 32 to 64 km (20 to 40 miles) and a top speed of 112 km/h (70 mph). Fuel efficiency is approximately 130 W·h/km (4.8 mi/(kW·h), which is equivalent to 162 mpg (US) or 194 mpg (UK) (1.45 L/100 km) using the DOE conversion.
Two models were produced: the original "jelly bean" model and then a hatchback model, which was nicknamed "pizza butt" because it was designed for use by Domino's Pizza. Several Sparrows were featured in the feature films Austin Powers in Goldmember and Looper.
In June 2008, the website listed a price of $29,995 without taxes or shipping. In 2009, the NmG began to use lithium batteries which Myers Motors claims doubled its driving range to 60 miles (97 km) between charges.
The Sparrow electrical system in a Corbin Sparrow VIN28 is composed of three isolated sections. "Defanging" is the process of changing the circuit to disconnect the high voltage from the low voltage.
- Line voltage
- 110 / 220 V AC
- Battery charger (on-board charger made by Zivan). It can be replaced by a Manzanitamicro PFC-20 or PFC-30
- Line voltage sensor
- High voltage
- 156 V DC
- A 20 kW (continuous) 156-volt DC traction motor (Advanced DC Motors 8-inch (203 mm) diameter, part #203-06-4004) 
- Motor controller (Zark VIN 28, DCP or KiloVac EVCL controllers)
- Energy is supplied by a battery pack composed of thirteen 12-volt deep-cycle lead-acid Optima batteries.
- Low voltage
- 13.5 V DC
- DC to DC converter
- Accessories: this includes cigarette lighter outlet, radio/CD player, ignition switch, cabin fan and heater, speedometer, horn, turn signals, automotive lighting (headlamps, taillamps and backup lamps), door switch, seat belt, brake alarms, power windows and windshield wiper.
