On my way to work this morning a pulled up to a stoplight directly behind what I thought was a hybrid Chevrolet Tahoe. Upon closer inspection, I discovered it was instead their flex fuel model. I’d seen the Flex Fuel logo/badge thousands of times on a handful of SUVs but I’d never researched how they compared to other cars in terms of cost and fuel economy. I wasn’t exactly sure what “flex fuel” even meant or how these models differed from conventional engines and hybrids. Knowing that you can purchase all three options in the 2010 Chevy Tahoe, I decided to take a closer look to compare and contrast the benefits of each.
