Autocrossing A Chevy Bolt EV?

Autocrossing a Chevy Bolt EV? As some of you are aware, last Saturday I completed my "Drive 313 miles on a single charge across the state of MD" journey successfully. By engaging in light hypermiling techniques and with some elevation help, I was able to stretch the Bolt's range over 31% past its official 238 mile EPA range number! What could I possibly do to follow up such a feat? Doing the polar opposite and entering my Bolt in an autocross event! For those of you not familiar with autocross, these types of events are usually held in empty parking lots with a track consisting of a series of tight turns marked by cones. As you can guess, handling, acceleration (and sticky tires) are the keys to the game in autocross as opposed to raw straight line speed in a drag race. Vehicles such as a Dodge Challenger Hellcat need not apply. Instead, modded Corvettes, Miatas, Scion FR-S's, Subaru BRZ's and the like rule the roost. And in my event's case, one helluva souped up '99 Dodge Neon! So what was I thinking entering my totally stock 2017 Bolt EV Premier in the event?


While the Bolt has the low end acceleration needed for autocrossing, its rather hefty weight (over 3,500 pounds) and unconventional shape (for an autocross event) are a couple of negatives. Racing on the Bolt's LRR OEM tires was also a huge disadvantage, as most everyone else was at a minimum running performance tires. The only preparation I did before the event was to wash and wax my Bolt (hey, it should at least LOOK nice) and empty out any random junk that was laying around inside the car. I aired up my tires to the max (as someone recommended) and I was off to Blue Crab stadium in Waldorf, MD! As the drive was 50 miles to the event location, I didn't need to charge before the event. If it's nice and shiny, it'll go a little faster right? After arriving at the autocross location and checking in, I drove to the "paddock" area where all the other drivers were prepping their cars. I quickly found out that I was the only electric car entered in the event.


When I went through tech inspection, one of the inspectors popped the hood, stared at the Bolt's "engine" bay for a few seconds, then went "I have no idea what I'm looking at!". Since nothing was loose that he could see, he passed the Bolt with a shrug of the shoulders. There were a total of 118 entrants in the event, and 3 heats scheduled consisting of A and B groups. As I had registered rather late in the process, I ended up in Heat 3, group B, so I ended up watching the other drivers make their runs. Before the actual event, drivers get a chance to walk the course to try and memorize the layout before making their runs. I also chatted up an owner of a 2016 Ford Focus ST. It turned out it was also his first time to an autocross event. I wished Abdullah luck, and I went off to watch some more runs.


The format for the event was fairly straightforward. There were 3 total heats consisting of A and B groups. While group A was making their runs, the B group was out on the track to call in missed turns and replacing hit cones. Numerous cones were sent flying during the day. After group A made 3 runs, group B went to their cars while group A replaced them on the track. When Heat 3 started, I was assigned to a section of track with 2 other guys. One of them asked me what I was driving, and I replied a Bolt EV. He then went "Oh, so you're the guy in the Bolt!". I asked them if they see any other EVs at these events, and both (including the guy that owned 6 cars total including a Miata he entered) said they had never seen an electric car at an autocross before. I asked about Teslas, but one guy responded they are too heavy for this type of event, so he had never seen one.
