Mercedes, Pirelli to face tribunal hearing over `secret` tyre test

London: Mercedes might face quitting Formula One if the International Tribunal decides that the team is guilty of getting a secret in-season tyre test conducted with Pirelli.

While Mercedes` expulsion from F1 is deemed unlikely, the case hearing in Paris where both Mercedes and tyremaker Pirelli will be inquired, could hit the team with a fine, a points deduction, a race ban or exclusion from the championship, the Sun reports.
