Prius travels 400,000km in 24 months

When it comes to stop-and-go traffic, hybrid vehicles are at their best in fuel efficiency. Traditional internal combustion engines (ICE) run constantly in traffic and as a result consume fuel and emit pollutants into the atmosphere.

Hybrids, on the other hand, operate on battery power when at a standstill. True hybrids like the Toyota Prius and Ford Escape Hybrid can travel at moderate speeds around town under full electric power -- as long as the battery is charged.

The reduction in fuel consumption and greenhouse gas emissions were enough for New York City Mayor Michael Bloomberg to declare that all yellow cabs would be hybrids by 2012.

"There's an awful lot of taxicabs on the streets of New York City obviously, so it makes a real big difference," said Bloomberg in late May. "These cars just sit there in traffic sometimes, belching fumes; this does a lot less. It's a lot better for all of us."

When it comes to the Toyota Prius, a Vancouver cab driver has shown that the mid-sized hybrid is up to the task of taxi duty. Andrew Grant and his partner operate a 2004 Prius that roams the streets 22 to 24 hours a day.

According to Grant, the Prius just surpassed the 400,000 kilometer (248,548 mile) mark. The Prius accomplished this feat by consuming just 10 to 15 liters of gasoline per 12-hour shift as opposed to 35 to 55 liters for traditional ICE taxis.

Over a 24-month period, the Prius had one-third less maintenance costs and there were no failures of the hybrid powertrain during 400,000 kilometers of driving. The lower maintenance costs coupled with a fuel savings of roughly 1,500 liters per month means that the Prius paid for itself in less than 24 months.

Grant's 2004 Prius is now the highest-mileage second generation Prius on the road. Not surprisingly, Toyota is interested in checking out the vehicle so it will soon be shipped to Toyota's Japanese headquarters for research.
