Hyundai IONIQ EV is the most efficient car on sale

Hyundai already announced that its electric car with a 28 kWh battery gets a 110 miles (177 km) EPA range. But now Hyundai has released its efficiency EPA figures. While city and highway efficiency rates are still unknown, the combined MPGe is 125.

The 125 MPGe (16,75 kWh/100 km) makes it the most efficient car tested by the EPA that is currently on sale.


These are the EPA top 5 most efficient cars:


  1. 2017 Hyundai IONIQ electric: 125 MPGe (16,75 kWh/100 km)
  2. 2017 BMW I3 BEV (60 Ah battery): 124 MPGe (16,88 kWh/100 km)
  3. 2017 Chevrolet Bolt EV: 119 MPGe (17,64 kWh/100 km)
  4. 2016 Chevrolet Spark EV: 119 MPGe (17,64 kWh/100 km)
  5. 2017 BMW I3 BEV (94 Ah battery): 118 MPGe (17,83 kWh/100 km)


Obviously the most efficient cars are also electric. Also important is that EPA measures the energy consumption for electricity from wall-to-wheel, this way the charging efficiency matters.


We’re still disappointed with the low battery capacity and the high price. But, Hyundai IONIQ EV does have some advantages. Its efficiency and fast charging rate.

Hyundai says that this electric car can charge from 0 to 80 % in just 24 minutes at a DC fast charger, that’s 56 kW in average, while the max charging rate surpasses 60 kW.


In late 2017, if Hyundai increases the usable battery capacity from 28 to 42 kWh while maintaining the weight, the EPA range can increase from 110 to 165 miles (265 km). In 2017, a 40 kWh battery is the minimum acceptable for electric cars that cost more than 30.000 € before government incentives.


Thanks Ralf K for the heads up.

My interest in electric transportation is mostly political. I’m tired of coups and wars for oil. My expectation is that the adoption of electric transportation will be a factor for peace and democracy all over the world.

It is frustrating. Had Hyundai wanted to, it could have had one of the strongest players on the market next year. Instead, they chose to announce a product that is obsolete already before it goes on sale. With 40 kWh useable it would have been a real contender, and with 50 kWh it’d be hard to beat. But at 28 kWh gross capacity it is a bad joke.

This proves Hyundai made an excellent EV but decided in the end to castrate it with a low capacity battery. To be serious they should release it with a minimum of 40 kWh battery and a fair price.

The higher range Hyundais are yet to arrive later. Current plan in: 200 miles in 2018; 250 miles in 2020.

For reference:

Hyundai could probably offer multiple (at least two) battery choices, a bigger one for range and a smaller one for affordability. I’m confident, they will react to the market demand that they experience.

I took part to a marketing research for the Ioniq and it was pitted against the Prius and and the Auris, both hybrids. The EV seemed to be just there to test waters.
