Feb.6 (GMM/Inautonews.com) Sauber on Monday joined the growing ‘stepped nose’ club by revealing its C31.

The Swiss team’s new Ferrari-powered car – boasting a modified grey, white and red livery – was revealed at Jerez before its initial laps “for filming purposess” ahead of the opening pre-season test.

Like most other cars revealed so far in 2012, the Sauber features the controversial ‘stepped wing’ solution.

Also spotted at Jerez was Toro Rosso’s new car, which has a stepped nose as welll. The Ferrari-powered TR7 will be launched later on Monday, as will Red Bull’s title-defending RB8.
