She's officially the fastest woman on Earth.

Race car driver Jessi Combs was posthumously awarded the fastest land speed record by a female this week when Guinness World Records posted it that it counted her speed, meaning she officially broke the record.

Combs, 39, died last year in an accident on the day of the attempt in the Alvord Desert in southeast Oregon.

Combs broke the record by clocking a speed of 522.783 mph in a jet-powered car. She's the first person to break the record in more than 40 years, Guinness said.

Stunt driver Kitty O'Neil, who in 1976 reached 510.710 mph at the same spot, held the previous record.

CNN reached out to Guinness for comment but did not immediately receive a response.

Terry Madden, Comb's partner, wrote in a long Instagram post that he doesn't know how to feel about the achievement, "as no record could ever be worth her not being here."

"But it was a goal that she really wanted - and as hard as it is for me to even look at the car without crying. I'm so proud of her," he added. "She woke up that morning to an alarm saying 'lets make history' and we had an absolutely amazing day."

That run was supposed to be her last attempt at the record, Madden said on Instagram.

The accident occurred when the front wheel assembly failed as she decelerated at the end of the run, coming apart, Madden explained. Combs had done everything right.

Combs was a legend in the automotive industry. Her resume was full of firsts: the first woman to place at any Ultra4 event; the first woman to compete in The Race of Gentlemen event.

She was dubbed the "fastest woman on four wheels" in 2013 when she set a race record of 398 mph at the North American Eagle Supersonic Speed Challenger.

 
 
 
 
 
 
 
 
 
 
 
 
 

#rememberthetime I was woke up Monday by a reporter from the London Times telling me that @guinnessworldrecords would be releasing today that @thejessicombs had officially broke her world landspeed record. I really don’t know how I feel about this at all as no record could ever be worth her not being here, but it was a goal that she really wanted - and as hard as it is for me to even look at the car without crying. I’m so proud of her. She woke up that morning to an alarm saying “lets make history” and we had an absolutely amazing day. On the morning run she broke her previous top speeds and we went back to the trailer and had a long heart to heart - she had a few things that were bothering us safety wise and I told her I would support her no matter what she decided to do. That afternoon we booked a house in Lake Tahoe for the next night, and she decided she was going to run that one last afternoon run to back up her record and then walk away from it for good and let her back up driver go for the overall world record instead of her. That was to be the last time she ever got in that car. It has torn me apart that all I had todo is say let’s go and we would have left before that run, she asked my opinion and I told her Togo for it if it was what she wanted. That conversation has torn me apart everyday since the accident. . On her final record run- the front wheel assembly failed and as she decelerated just past the end of the run, it came apart and went up into the electronics/mechanical bay behind her seat and caused the accident. There was nothing that she could do and she did everything perfect. I don’t know that this is anyone’s business and it has been hard for me to talk about, but I have been asked about several false narratives lately that she had done something wrong and I can’t live with anyone saying that anymore. I was in the safety vehicle beside her as she was slowing down when the accident happened, I watched the accident live as well as the onboard footage that was recovered. I can 100% tell you beyond any doubt that she did everything exactly as she was supposed to. . #missyababe #myjessi #landspeed #jessicombs #worldrecord #guinness
