For three seasons since 2010 RBR, McLaren and Ferrari have been well above other teams in the constructors' championship. In 2012 Lotus got close, but it wasn't enough to make a change. For how long will this trio keep holding the stranglehold of F1, sharing race wins between them? In 2010 and 2011 those three teams won all races, 2012 was a messy year but no other team bar those three got more than a single win.
Let's recall the past and similar status quo's.
2007-2008 had Ferrari, McLaren and BMW Sauber at the front. 2009 rules changed it and BMW pulled out.
2005-2006 had Renault, McLaren and Ferrari in top3. But with the disappearance of Michelin Renault dropped backwards.
2000-2003 Ferrari, McLaren and Williams were consistently at the top. From 2000 to 2002 they shared all wins between them. It took 2004 and truly underwhelming cars from Williams and McLaren to finally see them dropping out of top3 in constructors.
1994-1997 Williams, Benetton and Ferrari were top3. From 1994 to 1996 they shared all race wins between them except the bizarre race at Monaco in 1996. It took 1998 rule changes and Newey-inspired design for McLaren to break this group decisively.
