Racer and television host Jessi Combs — known as the “fastest woman on four wheels” — died in a fiery crash while attempting to beat her own land speed record, officials said Wednesday.

Combs, 39, was barreling through a dry lake bed in Oregon’s Alvord Desert on Tuesday afternoon inside a 56-foot-long, 52,000-horsepower “jet car” when the “horrific accident” happened, her team said.

Police officials told The Post on Wednesday that investigators were attempting to recover laptop computers that were on board the high-powered vehicle — dubbed the North American Eagle Supersonic Speed Challenger — so they could determine what went wrong.

“They’re waiting for the team to recover the [engine and systems] information stored on the inboard computers,” said Lt. Brian Needham of the Harney County Sheriff’s Office.

He said “there was a fire involved” but was unable to say whether Combs’ car hit something to cause the blaze.

Combs, a South Dakota native, spoke about the risks of land speed racing on social media, most recently in a post on Aug. 24.

“It may seem a little crazy to walk directly into the line of fire,” she tweeted, along with a picture of her jet car.

“Those who are willing are those who achieve great things. People say I’m crazy. I say thank you.”

The former “Mythbusters” and “Xtreme 4×4” host had competed as a member of the North American Eagle Supersonic Speed Challenger team, which she joined in 2013.

Combs’ family and teammates released statements Wednesday remembering her.

“Combs was one of the rare dreamers with the bravery to turn those possibilities into reality, and she left this earth driving faster than any other woman in history,” her family said.

“Surrounded by her family and friends at the time of her passing, Jessi lived fearlessly and her legacy lives on in the countless lives she touched.”

Combs was declared the “fastest woman on four wheels” after she piloted the North American Eagle at a speed of 398 mph in 2013 — a record at the time.

She wound up beating it three years later with a 440 mph run, — and then again two years after that with a speed of 483 mph.

Her boyfriend and teammate Terry Madden called her “the most amazing spirit” he had ever known in an Instagram post on Wednesday.

“I have never loved or been loved by anyone as much as this amazing woman,” Madden said.
