Opel - NHTSA Investigation closed

Rüsselsheim. On Friday the National Highway Traffic Safety Administration in the United States decided to close its investigation into the safety of the Chevrolet Volt which is similar to the Opel Ampera.

 

The NHTSA investigation concluded that “no discernible defect trend” existed and that “the vehicle modifications recently developed by General Motors reduce the potential for battery intrusion resulting from side impacts”. The decision by NHTSA is consistent with the results of GM’s internal testing and assessment.

 

Last year the Ampera already received the maximum five-star safety-rating from Euro NCAP. The enhancements developed by GM include modifications to the vehicle structure and the battery coolant system, which would provide the battery system with additional protection in a severe side impact.

 

  • Strengthening of an existing portion of the vehicle safety structure
  • An additional sensor in the reservoir of the battery coolant system to monitor coolant levels
  • A tamper-resistant bracket to the top of the battery coolant reservoir to help prevent potential coolant overfill

 

The enhancements are being incorporated into the Ampera manufacturing process as production resumes this month. Cars produced earlier will be retrofitted in Europe, before delivery to customers.

 

Opel plans to begin delivering the Ampera to customers from February onwards
