An aerodynamic upgrade introduced for the San Marino Grand Prix brought the pace of the car to approximately level with the Renault. At the United States Grand Prix, in Indianapolis, Ferrari were dominant all weekend, resulting in the first Ferrari one-two finish since the same race 12 months beforehand. This seemed to represent a genuine turning point for the car's competitiveness. Modifications throughout the season continued to improve the car's performance, to the point where it was considered the fastest package of all for the remainder of the season – the car won 7 of the last 9 races of the season. Massa claimed his maiden win at the Turkish Grand Prix and later won his home race in Brazil. As a result of the car's improved form, Ferrari and Schumacher were able to close the gap to Renault and Fernando Alonso in their respective championships. However, Schumacher suffered an engine failure while leading the Japanese Grand Prix which effectively ended his title hopes and Ferrari eventually lost out on the Constructor's title by only 5 points to Renault. The 248 did give Schumacher his final Formula 1 win in China.
