![]() What is Consumption % difference EPA vs.CarBuyer – Revolutionizing The Online Car Marketplace In Singapore A positive percentage (in green) means Edmunds exceeded the range estimated by the EPA, while a negative percentage (in red) means a vehicle fell short of its EPA range during our test. This figure is the difference between the EPA's range estimate and the range tested in Edmunds' real-world testing. This process takes into account charging losses in the Edmunds tested consumption number. The kilowatt-hours used from plug-in to a full charge are tracked and then we calculate the consumption based on the miles traveled (less the remaining range). What is Edmunds tested consumption?Īfter a vehicle completes its road loop and the battery is nearly empty, it's charged back to full capacity. We prefer to use a higher percentage of city road driving because we believe it's more representative of typical EV use. (We target 10 miles of remaining range for safety.) The miles traveled and the indicated remaining range are added together for the Edmunds total tested range figure. What is Edmunds tested range?Įdmunds begins with full battery charge and drives an electric vehicle on a mix of city and highway roads (approximately 60% city, 40% highway) until the battery is almost entirely empty. The recharge energy includes any charging losses due to inefficiencies in the manufacturer’s charger. The energy consumption is then determined mathematically from the recharging energy, the energy-discharge data from the vehicle, and the distance traveled for each cycle. ![]() In EPA testing, once a vehicle battery is depleted, it is recharged using the manufacturer-supplied charger for that vehicle. So a vehicle that uses 20 kWh/100 miles is more efficient than one that uses 30 kWh/100 miles. Unlike mpg, however, where a larger number is better (for example, a vehicle that gets 30 mpg is better than one that gets 20 mpg), a smaller number is better in kWh/100 miles because you are using less battery energy per mile. This value tells you how much energy in kilowatt-hours a vehicle would use to travel 100 miles. A battery stores energy in kilowatt-hours much like a gas tank stores fuel in gallons. ![]() What is EPA estimated consumption?Īkin to miles per gallon (mpg) for fuel-burning vehicles, this metric represents electric vehicles' energy consumption in kilowatt-hours per hundred miles (kWh/100 miles). So what's the real-world version? That's where Edmunds' EV range testing comes in. In short, there's certainly a method to the EPA's madness, but the process is laboratory-based, and EV owners don't drive their cars in a lab. The value of this correction factor, which is always less than 1 but greater than 0, is determined by the number of drive cycles a vehicle is tested on. The total distance traveled is then multiplied by a correction factor that the EPA has determined will more accurately reflect what drivers can expect to achieve in the real world. The following day, the vehicle is driven on a dynamometer - it's like a treadmill for cars - over successive simulated city and highway routes until the battery is depleted. In short, this is the approximate number of miles that a vehicle can travel in combined city and highway driving (using a mix of 55% highway and 45% city driving) before needing to be recharged, according to the EPA's testing methodology.īut what exactly is that methodology? First, the vehicle is fully charged and parked overnight. Manufacturer recommends a lower battery charge level for daily use to preserve battery life. *Range tested at maximum battery charge to align with EPA estimates. 2022 Lucid Air Grand Touring (19-in wheels)Ģ021 Ford Mustang Mach-E California Route 1Ģ021 Ford Mustang Mach-E Premium Ext Range RWDĢ022 Ford F-150 Lightning Platinum Extended RangeĢ022 BMW i4 eDrive40 Gran Coupe (19-in wheels)Ģ022 Porsche Taycan 4S Cross Turismo (21-in wheels)
