It's tough to drive a Formula 1 car around the streets of Monaco. Taking a car lacking in downforce around the tight two-mile circuit is one of F1's greatest challenges, and hence the round is usually accompanied by a burst of aerodynamic appendages to capture a little more grip.
As top speed around Monte Carlo is usually an irrelevance, the aero devices that crop up are usually creators of 'dirty downforce', from which the cost of drag is a lot greater but that is less of a hindrance when considered against other circuits.
Red Bull has brought the most visible changes to Monaco, dropping its nose scoop for a more conventional design to clinch a little more front-end stability, while the floor also got an overhaul with a selection of multi-faceted fins. But there were other additions on show further down the field.
