Despite the technological intricacies of the Blade, it’s actually just a simple looking cylindrical device that fits over your tail pipe. The blade increases fuel efficiency by decreasing the duration of “cold start” operations — that time where your vehicle emits the greatest amount of pollution — and increasing the volumetric efficiency—a fancy term that means the amount of air that an engine ingests relative to its theoretical maximum. The result is a carbon emissions reduction of up to 12 percent. The device’s filter also pull out particulate matter, little nasties that dirty air and water as well as your lungs.

 

 

Here are some of the results on gas mileage increases that the Blade’s Web site touts:

According to Sabertec, the Blade's laboratory fuel economy and emission testing were conducted by a California-based independent testing laboratory licensed by the California Air Resources Board. However, it’s important to note that fuel-saving devices similar to the Blade have not always lived up to their green claims. Check out this informative Popular Mechanics article to see what we mean.

 

If you really doubt the Blade’s claims to fame, we at MNN recommend cutting carbon emissions the old-fashioned way, no independent testing required. Try carpooling with someone to work, walking to the grocery store instead of driving, or even just avoiding car idling when you’re waiting in line at the drive thru. You’ll save money, gas and hey, maybe even the Earth.
