The series went to the wire where Cerruti had to settle for second in the championship.
After steadily improving over the previous four rounds, on the eve of the NZGP at Manfeild, Cerruti let slip some pretty impressive news. She had been told the deal had been done and she was now a works BMW driver.
"Three official BMW Italy cars were racing in the Superstars Series last year and I was not bad racing against them, beating them quite a few times," said Cerruti.
"Most people thought I had a fast car and because I was a girl, it was not possible to go fast. So they offered me a test in a BMW M3 and it went very well as I did the same lap times as one of their already official drivers.
"They then said they were going to do an official BMW GT3 programme in Italy and wanted me to drive for them."
Not only are BMW quite happy to have a fast lady in one of their works cars, they've also got her pencilled in for a couple of real big tin-top races. Cerruti will also be racing the Z4 GT3 in the Total 24 Hours of Spa, the Monza 3 Hours and the Barcelona 12 Hours.
"We are doing all the Italian GT3 championship from April until November as well as some very important endurance races," she said.
There are very few women racing at the sharp end of world motorsport and there's no discernable reason why they shouldn't be.
Most hi-tech modern race cars now have power steering, paddle shifts and sophisticated suspension so there is no need to be physically strong any more. Sure, you have to be physical and race fit, but not the size of a small house and able to throw engine blocks around.
"I don't really know why more women don't race. It might be because women are thought not to be able to go fast or have any talent for racing," said Cerruti.
"Many people have said I only win or finish on the podium because I'm lucky.
"They don't seem to think it might be because I have some talent.
"When I won in Monza the driver ahead out braked himself and ran off the track.
"It's not my fault he made a mistake and I think I'm the better driver because I didn't make a mistake. There's no luck in being able to drive fast and stay on the track," said Cerruti.
She went on to tell a story how a former FIA world champion (who she wouldn't name) was so frustrated at not being able to pass her that, on entering a corner, T-boned her - sending her flying across the circuit.
"It was crazy. Not only for me, because to do something like that is very dangerous. But he did it front of everyone else and they could all see he made such a big fool of himself.
"He was very nervous that I was in front of him and he couldn't get past - not because I was slow - he just couldn't get past. It was a bad show in front of everyone and I think he crashed into me because I was a woman. It was though, so good for me because he was such a s**t in front of everyone," said Cerruti.
The young Italian finished the 15-race TRS series in 16th place, out of 21 drivers, many of whom had raced in numerous single-seater categories all around the world.
Cerruti was one of the few drivers over the championship who accumulated points in every race and didn't bend the car. Just goes to show, if you keep the car inside the white lines you can beat anyone and if you drive with your brain, rather than your heart, you'll do all right.
