Mercedes, Bosch emissions lawsuit OK’d for U.S. class action

A federal judge in New Jersey allowed a class-action lawsuit accusing Mercedes-Benz USA and Robert Bosch of diesel-emissions cheating to proceed, denying motions by the defendants to dismiss the case.

The lawsuit alleges Mercedes teamed up with Bosch to program its BlueTEC vehicles to release illegally high, dangerous levels of emissions via a “defeat device,” similar to the that used by Volkswagen Group that sparked its 3-year-old emissions-cheating scandal.

Such defeat devices turn off or limit emissions reductions during real-world driving conditions but not during vehicle-emissions tests. A defeat device allows a vehicle to pass government emissions testing while exceeding pollution standards under real-world driving conditions.
