With today’s ever increasing gasoline prices, a question must be asked: which cars, currently sold in the United States, are the most fuel efficient? In other words, which top five gasoline powered cars (including hybrids but not plug ins) provide the most bang for you buck? It should be noted that this list excludes electric cars which tend to be the most efficient. Therefore, if buyers are strictly looking for efficiency, electric cars should take priority. However, if range is also important, this list will be very helpful.
1. 2018 Hyundai Ioniq Blue (Hybrid) - 58 MPG combined
This is the number one, most efficient car currently for sale in the US. Its price starts at around $22,000. This is the lowest available trim level for this model. This models amazing fuel efficiency is mostly due to its incredibly low weight. It also features an extremely low drag coefficient of just 0.24 an ultra low weight 12V battery and regenerative braking. All this is supported by a 1.56 KW lithium polymer battery pack.
2. 2018 Toyota Prius Eco Hybrid - 56 MPG combined
Starting price for this model is $26,165. The Prius is the forerunner of hybrids and by far the most famous and popular model, which at least partially explains its higher price range.
3. 2018 Hyundai Ioniq Hybrid — 55 MPG combined
Another top five entry is from Hyundai. Pricing for this model starts at $23,950. This is basically a more feature rich version of the Hyundai Ioniq Blue, adding a bit more luxury and connectivity, while retaining most of the efficiency features.
4. 2017 Toyota Prius Prime — 54 MPG combined
This model starts at $27 100. It is a plug in hybrid vehicle (PHEV) which includes a heavier battery and on board charging system. The gas engine is DOHC 16-valve Atkinson-cycle 1.8-liter inline-4, 95 hp, 105 lb-ft. The electric motor used is permanent-magnet synchronous AC motors with an 8.8 kWh lithium ion battery pack. It should be noted that this efficiency rating, for the purposes of this list, does not take into consideration the plug in option. Using PHEV would basically turn this car into an electric car, which is not part of this list.
5. 2018 Hyundai Ioniq PHEV – 52 MPG combined
This is a similar model to Toyota Prius Prime in that it is also a plug in hybrid vehicle (PHEV). If this feature were taken into consideration, the efficiency would be even higher. This model feature a massive 8.9 kWh battery pack. The gas engine is DOHC 16-valve Atkinson-cycle 1.6-liter inline-4, 104 hp, 109 lb-ft , whereas the electric motor is permanent-magnet synchronous AC motor, 60 hp, 125 lb-ft. Starting price for this hatchback is $27,000.
