Weekend review and results round-up from the European Grand Prix

Despite expectations that the engine mapping rules tweak/clarification (depending on your view) might give Red Bull a few headaches in Valencia, Sebastian Vettel ultimately took one of his most comfortable victories yet - in the least exciting grand prix of the year so far

Form-wise, the only change seemed unrelated to the regulations situation, as Ferrari closed in on Red Bull, while McLaren - temporarily, it hopes - dropped back.

While Formula 1 did not deliver much action on the Valencia streets, GP2 and GP3 certainly did, as the feeder series' topsy-turvy seasons continued, typified by Romain Grosjean winning on Saturday in GP2 then having a messy first-lap crash on Sunday.

Elsewhere, the big non-F1 news of the weekend was that nearly five years after his first IndyCar Series race win, Marco Andretti returned to the top step of the podium with a brilliant win in a very hard-fought Iowa race, while in NASCAR Kurt Busch turned his speed into a result and triumphed in the Sprint Cup Series' first road course appointment of the year at Sears Point.
