The Mercedes E-class sedan has 9 deaths, hence should not be on the list. AWD is an option, not a new model. Or you must split Model S's by drive configuration.
The Volt stat might include the crash where a M235 BMW driven by a 20-year-old with 4 recent prior high speed offenses (faster than a normal speeding ticket), hit the Volt broadside at very high speed. The BMW was traveling 115 mph in a 45mph zone, but reduced it's speed to 75 mph at time of impact (instead of trying to avoid the impact) when it tore through the Volt and launched into the air. It killed 3 people in Volt immediately and maimed the survivor. The BMW driver was not seriously injured. He is was sentenced to 30 years but will probably be out in time for Christmas 2019, since they suspended 18 years of the sentence, and you only need to serve 25% of your sentence, so 10%. This occurred in a residential zone directly in front of a busy school while there was an event being held there.
The convict will be able to regain his driver's license shortly after his release. He will probably get the felony expunged. Maryland, gotta love it. Could even get the Ted Kennedy Driver of the Year Award.
Cliff Notes: The Volt did not catch fire even though taking a direct 75mph lethal hit on the battery's most vulnerable surface.
