The Toyota Prius may be one of the efficient hybrid vehicles to operate but the production process of the popular gasoline-electric hybrid can be a dirty job. Toyota recently studied the car’s total environmental impact from factory to junkyard and found that the Prius was better than average in its segment in lifetime emissions of carbon dioxide, nitrogen oxide and sulfur oxide.
However, it was slightly on the bad side than average in emissions of nonmethane hydrocarbons and particulate matter. The Japanese automaker says this is case because manufacturing hybrid-only parts such as motors, inverters and nickel-metal hydride batteries consumes more energy and creates more emissions.
The Prius as in fact worse than the class average across all five emissions categories when looking at the “materials manufacturing” phase.
Toyota used the life cycle emissions assessments on 8 of its models in 2009 and used the findings to redesign such models as the Prius, Lexus RX 450h and HS 250h.
Refresher: Power for the 2011 Toyota Prius continues to come from a 1.8L 4-cylinder engine making 98-hp / 105 lb-ft of torque. Total output with hybrid system ““ 134-hp. That allows for 0-60 mph to come in 9.8 seconds with a top speed of 112 mph. EPA-rated fuel-economy comes in at 51/48 mpg.
