Electric Car tzero

The tzero is a hand-made electric sports car that was manufactured in limited numbers by the U.S. company AC Propulsion. The tzero on the Piontek Sportech kit car, built from a fiberglass body on a reinforced steel space frame with double-wishbone independent suspension and rack and pinion steering composed. AC Propulsion drivetrain has the AC-150, a single-speed electric system with a total length ratio of 9:1. Launched in January 1997, only three prototypes were built and plans for the commercial production were dropped mid-2003. The name comes from t 0, the mathematical symbol for a starting point in time.

A second prototype was built in August 2003, operated light of 6.800 Lithium-ion batteries that are similar to those that make up the batteries of laptop computers, giving it a 300 miles (480 km) range. Lighter than the original version of 700 pounds (320 kg), is the 2003 edition of 0-60 km / h in 3.6 seconds. The only translation limits of the cars top speed of just over 140 miles per hour (230 kph) at 13,000 rpm with the correct orientation, but it was never more than 105 miles per hour (169 km / h test). The basic price of the car was USD $ 220,000.

AC Propulsion also produced a portable engine-driven generator on a trailer like the Long Ranger, which is mounted behind the car and feed power to the batteries could become known, moved during the trip. The trailer used a 500 cc Kawasaki engine with 9.5 U.S. gallons (40 liters) fuel tank and achieved 30 to 35 mpg highway via at least 20,000 miles. It is rated at 20 kW DC output and can maintain 60 to 80 mph video footage of the backtracking function that enables drivers to easily return to a trailer through a set of slalom cones, can be viewed here.

The original version of the roadster runs on 28 Optima Yellow Top producing lead-acid batteries ft 150 kW (200 hp) and 177 · lbf (240 Nm) torque at 336 volts (this is 28 * 12-volt battery-equivalent) that the 1040 kg car rockets from 0 to 60 km / h in 4:07 seconds. The only translation limits of the car at speed limit 90 miles per hour (140 km / h min) at 12,000 rpm, although it is said that the early prototypes could be equipped with multiple ratio hit 155 miles) per hour (249 km / hr too with the single ratio, lead-acid models are the final quarter mile (400 m) drag race in 13:24 seconds can. The expected range per charge of the tzero with lead-acid batteries from 80 to 100 miles (130 up to 160 km) due to the consumption of only 180 Wh per mile (895 J / km) (DC) on the highway and through regenerative braking. Within an hour, the car can be calculated from 0-95%. The base price was this version USD to have $ 80,000.
