7.12.1.Henney Kilowatt
In 1959 an electric car called the Henney Kilowatt was produced for the National Union Electric Company (the producer of Exide Batteries).
The 1959 models ran on a 36-volt system that consisted of 18 sequential two-volt batteries. The 36-volt cars had a top speed of 40 mph (64 kph) and a maximum range of about 40 miles (64 km).
A 72-volt system was fitted to the 1960 model. It employed 12 sequential six-volt batteries. The 1960 Kilowatt had a top speed of nearly 96 kph (60 mph) with a range of over 96 km (60 miles).
It is thought that only 47 cars were built. 24 were sold as 1959 models and 8 as 1960 models. None of the 1960 models being sold to the public due to the high cost of the 72-volt system.
The last cars may have been sold as late as 1962.
7.12.2.General Motors
In about 1964 General Motors produced an experimental electric car called the Electrovair 1.
It was built to prove the feasibility of electric drive for passenger vehicles pending the availability of a practical high energy battery.
The electric car was a modified 1964 Corvair and was powered by zinc-air batteries. The drive system consisted of a 120 lb, 12,000 rpm, 3-phase induction motor, capable of producing 115hp.
In 1966 GM produced the Electrovair II. Twenty-two years later, in 1988, GM funded research to build a practical consumer electric car.
The resulting vehicle became known as EV1 and was based on a prototype vehicle called the Impact.
A modified EV1 prototype set an electric vehicle land speed record of 183.8 mph (294 kph) in 1994.
Between 1996 and 1999 GM produced 1,117 EV1 cars, which were only leased, never offered for sale.
The car had a top speed of 80 mph (128kph) and accelerated from 0 to 30 mph in under 3 seconds and 0 to 60 in under 9 seconds.
The EV1 cars were originally fitted with lead acid batteries and had a maximum range of 75 miles (120 km), which later increased to 100 miles (160 km) when fitted with 26 12V Panasonic lead-acid batteries.
By 1999 the cars were fitted with 26 13.2V Nickel Metal Hydride (NiMH) batteries and had a maximum range of 150 miles (240 km).
Towards the end of 2003 GM cancelled their EV1 program.
7.12.3. Sebring-Vanguard
A two-door, two-seater electric car called the Vanguard Citicar was produced from 1974 to 1976. It had a top speed of 44 mph (70 kph) and a typical warm weather range of 40 miles (64 km). Check the top speed figure.
It was fitted with 8 x 6V lead acid batteries. About 2,200 cars were produced.
In 1977 the company producing the car was sold and the new owner started to build a new version of the car, whilst maintaining the original shape. The original 3.8hp motor was replaced by a 5hp one.
The improved car was called “ComutaCar”. In about 1986 the ComutaCar Company ceased trading.
7.12.4. Chevrolet
About 500 Chevrolet Electric S-10 vehicles were produced between 1997 and 1999.
The S-10 EV was powered by a 114hp, three-phase, AC induction motor. The lead acid power pack consisted of 27 batteries. In 1998, lighter weight NiMH batteries were also available.
The car had a max range of 60 miles (96 km) and a top speed of 70mph (112 kph).
7.12.5. AC Propulsion
The Tzero was an electric powered sports car produced by the AC Propulsion Company. Three prototypes were built between 1997 and 2003.
The 2003 version was powered by 6,800 lightweight lithium-ion cells. It had a range of 300 miles (480 km) and accelerated from 0-60 mph in 3.7 seconds.
The car had a top speed of just over 140 mph (225 kph), although it was never run at greater than 105 mph (169 km/h).
7.12.6.Ford
The Ford Ranger EV was a battery powered electric vehicle that was produced between 1998 and 2002/3. 1,500 were produced.
The vehicle was fitted with NiMH batteries and had a range of about 65 miles (104 km).
7.12.7 Solectrica Corporation
The Solectria Sunrise was an electric car designed and built in the 1990s. It did not go into production and only a few prototypes were built.
In 1996 it achieved a range record of 375 miles (600 km) on a single charge.
