Chevrolet Volt battery safety tests prompt more fires, further investigation

2012-Chevy-Volt-Driver-SideEarlier this month, we reported that the National Highway Traffic Safety Administration was investigating potential safety issues related to electric car batteries — specially, the Chevrolet Volt — after a routine crash test resulted in a fire. While the agency hadn’t been able to replicate the incident at the time, subsequent tests of three Volt battery packs have resulted in three more incidents.

According to Automobile Magazine, the trio of lithium-ion battery packs were tested between November 16-18, and all three tests involved rupturing the vehicle’s coolant line and damaging the compartment that housed the battery. While the fire test didn’t result in a fire, there was a temporary increase in temperature reported the following day. The second battery caught fire seven days after testing, while the third began to smoke and emit sparks within hours of being damaged in the test.

In all three tests, the battery packs were impacted and then rotated to simulate a side-impact collision and roll.

The NHTSA and General Motors are now working to determine the cause of the fires, and there’s no word yet on whether there will be a recall. So far, the NHTSA hasn’t raised any concerns about electric vehicles other than the Volt, and there have been no fires reported by Volt owners.

Performance versions of ordinary cars have been a staple of the auto industry for decades. But while we’ve already seen some variants of EVs boasting more power and more impressive stats — think Tesla Model S Plaid or Lucid Air Sapphire — the 2025 Hyundai Ioniq 5 N is the first to truly apply that format to an EV.

Maserati is adopting electrified vehicles with open arms, and while that could potentially signal an identity crisis for the luxury Italian brand, that’s probably a good thing in the long run.

The company recently took the wraps off of the new Maserati GranCabrio Folgore, which is essentially a convertible version of its already released GranTurismo Folgore electric car. The new EV is its third go at electrified vehicles so far, and it flew us out to Rimini, Italy, to witness the big reveal in person.
