Hybrid & Electric Technology

Hybrid cars are powered by combined fuel technologies. Learn more about the technology behind these newer types of vehicles.

  • Quiz Yourself: Electric Cars  
      
    They may look similar from the outside. But there are many significant under-the-hood differences between an electric-powered car and a car that makes use of an internal combustion engine. How much do you know about electric cars?
  • Quiz Yourself: Hybrid Cars  
      
    With the constantly fluctuating -- and sometimes skyrocketing -- price of gasoline, more people are looking into hybrid cars. How do hybrids get such great mileage?
  • How Hybrid Cars Work  
      
    How does a hybrid car improve your gas mileage? And more importantly, does it pollute less just because it gets better gas mileage? Learn how hybrids work, plus get tips on how to drive a hybrid car for maximum efficiency.
  • How Electric Cars Work  
      
    Electric vehicles, especially EVs powered by fuel cells, are a compelling alternative to gasoline-powered cars. Find out how today's electric cars work to get you where you're going without gasoline.
  • How Plug-in Hybrid Cars Work  
      
    ooking for ways to further improve fuel-economy, manufacturers are exploring enhancements to the basic hybrid concept. One promising avenue is the plug-in hybrid car. Learn all about plug-in hybrid cars including their many benefits.
  • How Electric Car Batteries Work  
      
    Electric vehicles have been around since the first half of the 19th century; however, until recently, no reliable, mass-producible batteries were manufactured that could make electric cars competitive with gas-powered vehicles. That's beginning to change.
  • How Air-Powered Cars Will Work  
      
    Have you been to the gas station this week? If you have, you've surely decried the expense of gasoline. But in a few years we could see cars running on compressed air.
  • How Diesel-fueled Hybrids Work  
      
    Most people know gasoline-powered hybrid cars provide fantastic fuel economy. When you consider that the newest diesel engines are cleaner, more powerful and reliable, wouldn't it be great if an automaker built a diesel hybrid?
  • How Hydraulic Hybrids Work  
      
    Flying down the highway, a hydraulic hybrid isn't much different from a regular car. But in traffic, the vehicles can increase fuel economy 40 to 70 percent. How do they do it?
  • Are some hybrids just greenwashed?  
      
    With consumers hungering for fuel-efficient hybrids, carmakers are pumping up their models' green reputations -- sometimes to the point of greenwashing. Could the greenest thing about your hybrid be its color?
  • Is there a way to create an all-electric car you don't have to plug in?  
      
    Don't be fooled: Even all-electric cars have a carbon footprint. How do they pollute? And how close are we to developing one that's truly a friend to the environment?
  • Will I get shocked if I drive an electric car through a big puddle?  
      
    Both hybrid and electric vehicles use battery packs to power electric motors. Some systems are capable of generating 300 volts or more. Isn't it dangerous to drive these high-voltage cars through deep puddles?
