EPA Requires Audi, Bentley, Porsche and Volkswagen to Correct Fuel Economy Labels for a Number of 2013-2017 Gasoline Powered Vehicles
Contact Information: EPA Press Office (email@example.com)
WASHINGTON (August 30, 2019) — The U.S. Environmental Protection Agency (EPA) is revising estimates for a number of 2013-2017 Audi, Bentley, Porsche and Volkswagen vehicles to ensure consumers are given accurate fuel economy values. EPA is also requiring the Volkswagen Group to forfeit emissions credits under the greenhouse gas (GHG) emissions standards for light duty vehicles to account for under-reporting emissions.
In the course of the investigation concerning defeat devices in Volkswagen’s diesel vehicles, the EPA and the California Air Resources Board discovered that the company employed software to manage vehicle transmissions in gasoline vehicles. This software causes the transmission to shift gears during the EPA-prescribed emissions test in a manner that sometimes optimizes fuel economy and greenhouse gas (GHG) emissions during the test, but not under normal driving conditions. The company employed this software in roughly one million gasoline, light-duty vehicles from model years 2013 through 2017 sold by Volkswagen in the United States under the brand names Volkswagen, Audi, Porsche, and Bentley.
The EPA required Volkswagen to estimate the emissions and fuel economy impact of the software through extensive testing and other methods. Based on these investigations, Volkswagen found that, deactivation of the software resulted in an impact to fuel economy on roughly 98,000 vehicles of approximately one mile per gallon.
Just as Volkswagen over-stated the fuel economy of these vehicles, the company under-stated greenhouse gas emissions by approximately 220,000 metric tons. To account for these discrepancies Volkswagen will forfeit approximately 220,000 GHG emission credits under EPA’s light duty GHG emissions standard program. Volkswagen will also forfeit credits in the federal Corporate Average Fuel Economy program. The exact amount of credits will be subject to approval by EPA and the National Highway Traffic Safety Administration.
EPA’s National Vehicle and Fuel Emissions Laboratory conducts fuel economy testing on vehicles each year to ensure that their performance matches the mileage and emissions data automakers submit to EPA. These audits are part of the oversight program that helps ensure all carmakers are following the same procedures for calculating mileage estimates. The oversight program also helps the EPA verify that vehicles on the road meet national tailpipe emission standards to protect public health and the environment.

I got your special software right here...[h=1]Volkswagen Used Special Software to Exaggerate Fuel-Economy Claims, EPA Says[/h]
Well, today comes a new scandal with a new engine, the EA288 (english coverage), which was designed to replace the EA189. Internal VW documents acquired and reviewed by SWR over the course of a Dieselgate lawsuit relate to the vehicles’ new AdBlue (urea) injection system, which is used to reduce emissions. According to the documents, the software for the engine was designed to detect the NEDC emissions testing, and if so, increase the amount of AdBlue it would inject, but otherwise reduce it in order to reduce AdBlue consumption to levels acceptable to consumers.
Volkswagen denies that its new engine contains any defeat software. “We investigated this topic since 2015 and the results of all investigations and measurements confirm to our current knowledge, the realization that the use of driving curves in the EA288 engine have no impact on compliance with emission limits.” Yet the internal documents lay out a detailed cheat plan, from how to detect the cycle to the exact dosings of AdBlue if detected vs. if not detected.
The EA288 engine is found in hundreds of thousands of cars, including the Golf, Tiguan and Passat.
The current case related to the EA288 is still active, vs. the previous EA189 scandal which was confirmed in the judgement of the court, and which Volkswagen is appealing. These revelations come at a bad time for Volkswagen, who since Dieselgate has pursued a strategy of focusing on statutes of limitations to avoid liability to customers who sued the company over its former defeat devices. Since the recent incidents would comprise new cheats, their presence has the ability to reset the clock on the statute of limitations.
