La agencia ambiental de Estados Unidos (EPA) acusó ayer al Grupo VW de haber instalado un software para falsear datos de emisiones contaminantes en sus motores V6 TDi (3.0 turbodiesel). El organismo asegura que estos motores salieron de fábrica con una trampa similar a la que tienen los EA189 (turbodiesel de cuatro cilindros).

Sin embargo, mientras que con los EA189 la automotriz alemana admitió de inmediato su responsabilidad, con los V6 TDI reaccionó de manera diferente: negó por completo la presencia de cualquier software engañoso.

Los V6 TDi se encuentran entre los turbodiesel más potentes de los modelos Passat y Touareg. También son utilizados por modelos de Audi y Porsche. Además, este impulsor es el que está siendo ensayado para una posible V6 de la Volkswagen Amarok (leer más).

En la Argentina, Volkswagen ya notificó a todos los propietarios de los modelos con los motores EA189 que tienen el software que engaña a los ensayos de emisiones contaminantes (ver listado por número de chasis).

El Grupo VW se puso a disposición de EPA para aclarar esta nueva acusación por los V6 TDi.

A continuación, se reproducen los comunicados de prensa de EPA, Volkswagen y Porsche sobre esta nueva acusación.

Comunicado de prensa de la Environmental Protection Agency EPA, California Notify Volkswagen of Additional Clean Air Act Violations

WASHINGTON – Today, EPA is issuing a second notice of violation (NOV) of the Clean Air Act (CAA) to Volkswagen AG, Audi AG and Volkswagen Group of America, Inc. This NOV is also being issued to Porsche AG and Porsche Cars North America. These five companies are collectively referred to as Volkswagen (VW). The NOV alleges that VW developed and installed a defeat device in certain VW, Audi and Porsche light duty diesel vehicles equipped with 3.0 liter engines for model years (MY) 2014 through 2016 that increases emissions of nitrogen oxide (NOx) up to nine times EPA's standard. The vehicles covered by today's NOV are the diesel versions of: the 2014 VW Touareg, the 2015 Porsche Cayenne, and the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L, and Q5.

EPA and the California Air Resources Board (CARB) have both initiated investigations based on Volkswagen's alleged actions. The NOV covers approximately 10,000 diesel passenger cars already sold in the United States since MY 2014. In addition, the NOV covers an unknown volume of 2016 vehicles.

These alleged violations are in addition to the NOV issued on September 18th and the ongoing investigation by EPA alleging a defeat device on certain 2.0 liter engines for MY 2009-2015 vehicles.

"VW has once again failed its obligation to comply with the law that protects clean air for all Americans," said Cynthia Giles, Assistant Administrator for the Office for EPA's Enforcement and Compliance Assurance. "All companies should be playing by the same rules. EPA, with our state, and federal partners, will continue to investigate these serious matters, to secure the benefits of the Clean Air Act, ensure a level playing field for responsible businesses, and to ensure consumers get the environmental performance they expect."
