Students learn quiet NASCAR skills at electric car event – Anniston Star

Students learn quiet NASCAR skills at electric car event – Anniston Star
26 Jan

OXFORD — As Oxford High School student Ashley Paulson,16, was drafting another electric car in the inaugural Oxford Green Prix — an electric car competition at Choccolocco Park Saturday morning —  she heard a loud bang.

“The tire just popped. I was driving the car and trying to follow along with the 777 car and get some speed off of them and it just popped, I must have hit a bump or something,” said Paulson.

Paulson’s black car, No. 888, limped back to pit row where the Oxford High pit crew feverishly fixed the flat and she was back out on the one-mile course which snaked around baseball fields to compete with the other schools.

The electric cars, competing in the two-day event, are a modern and updated version of traditional soap-box derby cars, according to Drew Sparks, president of Greenpower USA. 

Greenpower USA not only sells the cars and accessories but it is also the sanctioning body for races, according to Sparks.

“We’ve got 33 teams from across the Southeast competing in the Greenpower USA electric car competition. Today the teams are trying to see who can go the farthest distance in 90 minutes,” said Sparks.   

The whir of the electric motors and the sound of the rubber tires rumbling on the pavement were the only sounds the cars made as they whizzed by spectators with a top speed of 25 mph. 

“All of these cars are run off two 12-volt lead acid batteries so everybody is on the same power source, everybody has the same motor,” said Sparks. 

Sparks said that teams can change tire composition, tire pressure, gear ratios and add electrical components to make the car more efficient as long as they stay within the rules for that category.

“This is the modern day soapbox derby, we added a little more ‘umph’ to it with battery power but it’s very similar to those events,” Sparks said. “I think that’s one thing that gets a lot of the kids interested because they’ve heard all the stories from their parents about the soapbox days and now this their version of that.”  

During the 90-minute race each team must have three different drivers.

“It’s almost like a true pit change like you see in NASCAR minus changing all the wheels and tires,” said Sparks.

Another similarity to NASCAR is the points system for each category which are stock, modified and custom.

“You get bragging rights for being at the top. and Oxford High School is at the top of their category,” Sparks said. 

Sparks said there are 400 teams across 20 states and the participation is growing. Last year there were 14 events and this year 21 events are scheduled according to Sparks. 

“The program is growing, it’s really exciting to see what the kids are doing,” said Sparks.

The cars, in kit form, are available from the Greenpower USA at a cost of $5,000. 

Drivers, pit crews and supportive parents were all bundled up to stay warm Saturday morning as temperatures were in the 30s and 40s. 

Dave Frederick, engineering teacher at James Clemens High School in Madison and the team’s coach, said the cold weather on Saturday actually helps the cars run better. 

“In hot weather the motors tend to overheat causing higher resistance and slows the cars down a little bit,” said Frederick.

When the cars take off from the pit row members of the pit crew have to “push” the car off to help it get going.

Joseph Lane, 16, from Harlem High School in Georgia, pushed his team’s car during a pit change.

“We’re going four years strong right now with that same car, it’s a modified car, we’ve gone to Indianapolis Motor Speedway once, we got first place there,” said Lane.

Angie Rowe, from Oxford, was there to watch her son during Saturday’s action.

“I think that it is absolutely amazing to watch these kids. They’re given a kit and they’re given dimensions and a list of things they can and can’t do…I think it’s phenomenal,” said Rowe.
