Buying a hybrid is a responsible environmental move but, given their premium over standard cars, they aren't always a money-saving purchase. A study by CarGurus showed that gas would have to top $7 a gallon to make most hybrids the purely economical choice compared to standard models.
Hybrids command, on average, a 17-percent markup over their standard-powertrain counterparts, which stunts their economy at the pump. The $7-a-gallon break even point is an average. For some cars, the break-even is point is even higher. For a Cadillac Escalade Hybrid to make you money, gas will need to climb to $15 a gallon.
On the lower side of the scale are the Toyota Camry Hybrid and Ford Escape Hybrid. The Toyota's break-even point came out to $4 a gallon, while the Ford bucked the trend, breaking even at $2.50 a gallon.
