Teams and drivers head to the Sochi Autodrom this week for round 15 of the 2015 Formula one World Championship, The Russian Grand Prix.
In 2014, the Russian Grand Prix was something of a novelty: the new race on the calendar, filled with challenges unknown. A year on, the novelty is diminished but the challenges remain: the Sochi Autodrom is a highly technical circuit and difficult to get right.
The circuit is characterized by hard braking into low speed corners. Last year it proved to be a a power track, at which traction was a key performance consideration. It proved a tough circuit on which to follow another car closely, and thus overtaking opportunities were rare. Grid position and a strong opening lap are considered vital.
