With a lifelong desire to become a race car driver, Combs' record-setting run was made on the Oregon Alvord Desert, a 13 mile long dry lake bed, on October 9, 2013. When it comes to competitive driving, Combs feels right at home in the driver seat, Jessi is the fastest woman on 4-wheels. The vehicle used to break the record is the North American Eagle Supersonic Speed Challenger producing 52,000 hp. The land speed record vehicle started life as an F-104 Lockheed Starfighter. 

Interestingly, when the land speed vehicle was actually a jet fighter it served as a chase plane for the X-15 experimental jet and the SR-71 Blackbird. The jet car weighs 13,000 pounds and is 56 feet long from nose to tail and 7 feet across at its widest point. Power comes from a GE LM-1500 turbojet engine.

The jet engine sucks down 40 gallons of fuel per minute at idle and when running full bore requires 80 gallons of fuel per minute. With the afterburner activated, the land speed record vehicle needs 90 gallons of fuel per minute. The vehicle was originally developed to achieve much higher speeds and was modified to be run as a "car" with four wheels under FIA rules for Combs' run.

The vehicle was fitted with four wheels made from billet aluminum. Ultimately, the vehicle hopes to break the overall land speed record of 761 mph sometime in 2014 as a three-wheeled vehicle. Combs also plans to chase the overall female speed record of 512 mph. 

Jessie Combs is also a 2014 Ultra 4 Spec Class National Champion with Falken Tire. In 2016 she took 1st place in King of the Hammers with the Savvy Off Road team in the EMC Modified Class and a 2017 12th place finish in the Unlimited Class driving the same Stock Mod car. In 2004, she graduated from WyoTech in the Collision & Refinishing Core Program, as well as the Street Rod Fabrication and Custom Fabrication and High Performance Powertrain programs, all at the top of her class.

While her chosen career path didn't initially include time on television, from October 2011- October 2014 Jessie Combs served as one of the hosts of All Girls Garage on Velocity. The basis of the show is females repairing and upgrading new and classic automobiles. Her on-screen personality  took shape as she honed her skills as a TV host while maintaining her integrity as a metal fabricator, builder and industrial artist. In May, 2012, Combs became a co-host and a guest fabricator with Chris Jacobs for the new sixth season of Overhaulin's re-launch on the Velocity and Discovery Channels. The training associated with her film career has allowed Jessie to become a performance driver for the film and commercial industry. Jessie is also working towards starting her own metal fabercation shop.
