"What this team has achieved over the past year is unbelievable".
An emotional Schumacher hugged his team after finishing on the podium for the 13th time in 29 races this season. "I'm absolutely delighted, I still can't quite believe it" said Schumacher, whose first win came at his father's favourite Spa circuit in Belgium.
That was trimmed to 39 points on Saturday morning after he finished 12th despite fighting his way up the field after a clash early in the race with his Prema teammate Marcus Armstrong saw both drivers head to the pits for repairs.
The presence of the German teenager with the famous name generated huge media interest in F3 this season.
Schumacher had been a picture of concentration in the final laps to hold second and secure the title, but punched the air after crossing the finish line.
Victory at the half-way stage heralded a remarkable run when Schumacher finished on the podium in nine of the next 12 races. The 19-year-old has been tipped by many to trace his father's footsteps in F1.
In December 2013 however the sporting icon suffered a major head injury while skiing in the French Alps and was put in a medically induced coma after undergoing two life-saving operations at Grenoble Hospital in France.
The German was undoubtedly the standout driver of the second half of the season.
That's one more racing title for the Schumacher family.
With the spotlight permanently aimed at young Schumacher, he was fiercely guarded from reporters' questions by Sabine Kehm, his father's manager.
It also qualifies him to race in Formula One next season, although there are few vacant seats available and the next obvious step would be Formula Two.
