Forbes released their annual list of the 2011 Worst Cars On the Road. There's no surprise about the vehicles listed, if you sat there and thought about it before you saw the list, you could easily guess half.

Cadillac Escalade

Chevy Tahoe Hybrid

Chevy Colorado

Chevy Aveo

Chrysler Town and Country

That leads me to wonder what exactly is their logic behind this list. So I did a little digging. Usually when outlets release their opinions on the Worst Cars on the Road, they usually look at it from one angle- either the MSRP or the MPG. According to Forbes they said that they "started with the lowest-rated vehicles from six reliability and performance studies conducted this year. Those studies are all from Consumer Reports: The Most Reliable Cars Report; Best and Worst Values Report; Highest Cost of Ownership; Best and Worst Safety Performance Survey; Best and Worst Fuel-Economy; and the CR overall scores for 2011 vehicles.
Any car, truck or SUV named among the worst in at least three of those six total studies made the final cut to be on the "Worst-Made" list".
