EPA Rates Them All; Finds Plug-ins Best;
100 MPGe May Be The New 40 MPG.
The federal Environmental Protection Agency spends a good portion of its time and manpower compiling a guide that compares like vehicles’ fuel economy, spaciousness (interior space) and engine technology. The result for 2014 vehicles (cars and trucks) is now available on www.fueleconomy.gov and has a new benchmark – the Top 10 fuel economy cars all feature a plug. Some are pure electrics and others are plug-in hybrids. The fuel economy numbers are astronomical by historical standards, but are setting the new benchmark for what a modern automobile needs to achieve to be considering a state-of-the-art environmental leader.
The side story to this list is that being a high-mileage hybrid or diesel (or gas-powered car) is fine, but it doesn’t set you apart as a true leader in the fuel economy department anymore. Not that long ago we were talking about
Spark EV-King of the HIll
40 MPG being the floor for an efficient vehicle; already, it looks like 100 MPGe (equivalent to gasoline miles per gallon on an energy basis) is now the ticket to be among the leaders.
Here are the Top 10 for 2014, with some commentary about each. Of course the biggest caveat is that these fuel economy numbers by design are miles per gallon equivalent, since some of these cars use no gas at all and others are capable to running for a significant amount of time without any petroleum.
1. Chevy Spark EV – 119 MPGe – Chevy’s spunky little electric car takes top honors in the fuel economy race with its efficient electric powertrain. When we tested it, the Spark EV lived up to its billing.
2. Honda Fit EV – 118 MPGe – Honda comes close to Chevy with its slightly larger Fit EV, though neither car has scored significant sales this year. Price cuts brought buyers into the showroom, but sales are still averaging less than 50 per month.
3. Fiat 500e – 116 MPGe – Right in the mix (after all, what a few MPGe’s when you’re into triple digits) is the fun little Fiat electric car. We gave it a spin and came away very impressed with the Italian approach to the EV.
4. Nissan Leaf – 115 MPGe (2013) – Even though it’s the best selling pure electric car, the Leaf was not included in the EPA listing for 2014 models since its 2014 model doesn’t launch until next month, but it is unlikely its
Best-seller and Top 4 MPGe
MPGe will change so we’ve included the 2013 numbers. We have spent plenty of time in the Leaf and find it to be well-suited to the task of almost replacing your internal combustion car.
5. Honda Accord PHEV – 115 MPGe – Honda’s engineers have scored a very impressive feat by producing a plug-in hybrid that turns in fuel efficiency numbers on par with pure electrics. Well received in the marketplace – and just named Green Car of the Year – we were impressed when we first had a chance to drive the Accord.
6. Mitsubishi i-MiEV – 112 MPGe (2013) – Another model missing from the 2014 EPA listing is Mitsubishi’s quirky electric car. As is the case with most plug-ins, it has struggled to find customers (although selling twice as many as the Fiat 500e or Honda Fit EV), which led to a price drop in the new model.
7. Smart fortwo ED coupe/conv – 107 MPGe – The diminutive Smart has a couple things going for it – it’s the only convertible electric car on the U.S. market right now, and it’s on its third generation and shows the lessons learned from earlier iterations. The zippy two-seater is primarily found in car-sharing programs.
8. Ford Focus Electric – 105 MPGe –
9. Ford Fusion Energi PREV – 100 MPGe –
10. Ford C-Max Energi PHEV – 100 MPGe (2013) – We can close out the Top 10 with a triumvirate of Ford models – its pure electric Focus and two plug-in hybrids (dubbed Energi), the Fusion sedan and C-Max wagon. having three models gives Ford the most variety of any automaker in the high-MPG stakes, although even with three models its cumulative sales still trail the single model sales of the segment leaders – the Leaf, Chevy Volt and Tesla Model S. That said, they are competent vehicles and have been building sales. They also represent a piece of Ford’s strategy that has the plug-in models offered along with non plug-in hybrids.

Bubbling under the Top 10: While the task of being in the Top 10 in MPG (or MPGe) is getting more difficult every year, three models that are right below the No. 10 cutoff can claim other marks that may be even more impressive. They represent three of the top four best-selling plug-in cars (the other is No. 4 Nissan Leaf) of the most recent month (October 2013), a mark that in some ways is more impressive than their still-hefty fuel economy numbers. The three are:
- Chevy Volt – 98 MPGe
- Toyota Prius PHEV – 95 MPGe
- Tesla Model S 60/85 – 95 MPGe/89 MPGe (2013 numbers)
BMW’s i3 will probably land in the Top 10
Two more to keep an eye on: Two vehicles (with three models) appeared to have not made the testing deadline for inclusion in the EPA guide, but can be expected to be in the mix as soon as their numbers are finalized. BMW’s new i3 (which will have a pure electric as well as a range-extended version with a small gas engine) will probably make it into the top 10 and bump out one of the Fords. Cadillac’s ELR coupe, since it is based on the Chevy Volt architecture, will probably turn in similar numbers to its four-door cousin so not crack the Top 10.
Missing in action: Gone from last year top fuel economy list are the Scion iQ electric, Coda sedan and BYD e6. None of the three made much of an impact although the latter two did represent the first Chinese cars on sale in the country and BYD is still likely to return with more models later in the decade.
Two new cars for 2014 that didn’t have reported numbers in the EPA guide and probably won’t make the Top 10 are exotic hybrids – the McLaren P1 and Porsche Panamera S E-Hybrid. Both are wonderful examples of technologies but are unlikely to have the efficiency of the more mundane models on the list. The price for the Porsche starts at $100,000 while the McLaren will run a staggering $1.15 million.
