Toyota Prius Plug-in
- Mpg: 51 city/49 highway
The Toyota Prius Plug-in Hybrid is the biggest gas saver in the Prius lineup. The standard model starts at $32,000, and the advanced model begins at $39,525.
The Plug-in gets its power from a 1.8-liter, four-cylinder gas engine combined with an electric motor system, as does the standard Prius. Combined they put out 134 horsepower, Edmunds says. The Plug-in uses a 4.4-kilowatt, lithium-ion battery instead of the nickel-metal hydride found on the standard Prius.
Prius says the Plug-in EV Mode will take you 11 miles on a full charge. After that, the electric and gas engines work together until the battery runs out. That gives it a combined 95 mpge and a combined 50 mpg with just gas, according to the EPA.
The Toyota Prius C also made the EPA's list, with the base model starting at $18,950. The C is the smallest in the Prius lineup and gets a combined 50 mpg, according to the EPA.
Starting at $24,000, the standard Toyota Prius is also in the lineup of energy-efficient cars. EPA ratings put the combined mpg at 50, the same as the Prius C. But the 51 city mpg of this Prius is a slightly lower than the C, and the 48 highway mpg is slightly higher.
