What is the Difference Between MPG and MPGe?

Since the release of the first hybrid vehicle over 20 years ago, the car market has added more and more electric power as the years pass by. In the present day, almost every auto manufacturer has at least one vehicle with some form of electric power in their lineup, whether it be hybrid, plug-in hybrid, or all-electric. With the rise of electric power, there needed to be a way to measure a car's efficiency. That's why the phrase MPGe was born, standing for miles per gallon equivalent. With Jeep's release of the new 4xe plug-in hybrid powertrain, we'd like to give you some information about MPGe to help you better understand it. Continue reading below to learn more!
What is MPGe?
As was mentioned above, MPGe stands for miles per gallon equivalent, meaning it is the electric equivalent of how far you can travel on a gallon of gasoline. The Environmental Protection Agency created MPGe in 2010 when they decided a measurement of efficiency for vehicles that use alternative energy sources, including electricity, was necessary. Of course, electric vehicles don't use gallons of gas; they use kilowatts of electricity, so the measurement could not be the same. But drivers still wanted to know how efficiently their car was running. MPGe isn't an exact one-to-one comparison, but it gives drivers the most accurate estimate of their hybrid or EV's efficiency. If you're interested in a plug-in hybrid electric vehicle (PHEV) like a Jeep 4xe, you may notice that the window sticker has both MPG and MPGe ratings. This is because PHEVs gives drivers the option to choose between gas-only, electric-only, or hybrid power.
How is MPGe Determined?
To measure a car's miles per gallon, the EPA simply measures how far it can travel on a gallon of gas. Getting the electric equivalent of that is a bit more complicated. First, they had to figure out how many kilowatts of electricity were the equivalent of one gallon of gas. This was determined to be 33.7-kilowatt hours (kWh). Therefore, if you see that a car gets 56 MPGe on a window sticker, this means that it is able to travel 56 miles on 33.7 kWh of the battery's charge. Something besides the MPGe to pay attention to when shopping for a PHEV is the range. When speaking about electric vehicles, you'll hear the word range tossed around a lot. An EVs range is how far it can drive on a full charge. While shopping for a PHEV, you'll see two ranges. One is the total range, which is how far you can drive on a full tank of gas and a full charge. The other is the electric range, which measures how far you can travel solely on electric power with a full charge.
Jeep 4xe Information
Beginning in the 2021 model year, Jeep revealed the 4xe PHEV system, which marked the first step in their "Zero Emissions Freedom" pursuit. While Jeep has stated the 4xe system will be available for the entire lineup by 2025, it is available for the Grand Cherokee and Wrangler heading into the 2023 model year. The 4xe powertrain features a 2.0-liter turbocharged inline-four cylinder engine gas-powered engine, an EV battery pack, and a pair of electric motors. The first electric motor is placed in front of the engine in place of the traditional alternator. Meanwhile, the second sits inside the transmission, taking the place of the conventional torque converter. The 4xe system gives both the Grand Cherokee and Wrangler 375 horsepower and 470 lb-ft of torque. For efficiency numbers, the Wrangler 4xe gets 49 MPGe, a 21-mile all-electric driving range, and 370 miles of combined driving range. Meanwhile, the Grand Cherokee 4xe offers 56 MPGe, 440 miles of total driving, and 25 miles of emissions-free driving.
