1: Chevy Tahoe Hybrid
The 2008 economic recession had everyone on edge, and the first automotive segment to get hurt was full-size SUV models. Back before crossovers were all the rage there were only the full-size dinosaurs that roamed the roads. The Tahoe in particular got horrible gas mileage and was the furthest thing from being fuel efficient (via Car and Driver).
What was their answer? Slap a hybrid drive-train into the Tahoe and call it economical. The problem with this theory was that the Tahoe Hybrid was not much more fuel efficient than the regular models. The hybrid drivetrains back in 2008 were not as advanced as they are now, and the Tahoe Hybrid was a much more limited vehicle. Nowadays, this SUV is sort of a collector’s item. You’ll still see them on the road from time to time but it’s a rare sight.
