Circuit de Monaco is a street circuit laid out on the city streets of Monte Carlo and La Condamine around the harbour of the principality of Monaco. It is commonly referred to as "Monte Carlo" because it is largely inside the Monte Carlo neighbourhood of Monaco.

The circuit is used on one weekend in the month of May of each year to host the Formula One Monaco Grand Prix. Formula One's respective feeder series over the years — F2, F3000 and today GP2 — also visit the circuit concurrently with Formula One.

History

The idea for a Grand Prix race around the streets of Monaco came from Anthony Noghès, the president of the Monegasque car club and close friend of the ruling Grimaldi family. The inaugural race was held in 1929 and was won by William Grover-Williams in a Bugatti.

Characteristics

The building of the circuit takes six weeks, and the removal after the race another three weeks. The race circuit has many elevation shifts, tight corners, and a narrow course that make it perhaps the most demanding track in Formula One racing. Despite the fact that the course has changed many times during its history, it is still considered the ultimate test of driving skills in Formula One. It contains both the slowest corner in Formula One (the Loews hairpin, taken at just 50 km/h (31 mph)) and one of the quickest (the flat out kink in the tunnel, three turns beyond the hairpin, taken at 260 km/h (160 mph)).

Due to the tight and twisty nature of the circuit, it favours the skill of the drivers over the power of the cars. However, there is very little overtaking as the course is so narrow and dangerous. Nelson Piquet likened racing round the course to "riding a bicycle round your living room". Prior to 1987, the number of cars starting the race was limited to 20, compared to 26 at other circuits. The famous tunnel section (running under the Fairmont Hotel, marked in grey in the circuit diagram above) is said to be difficult for drivers to cope with due to the quick switch from light to dark, then back to light again, at one of the fastest points of the course. As a result, race outcomes tend to be decided by grid positions as well as pit strategies.

Several attempts have been made to improve cramped conditions in the pit garages. In 2002, a substantial amount of land was reclaimed from the harbor to slightly change the shape of one section of the circuit; this left more space for new pit garages, which debuted in the 2003 event.

The circuit is generally recognised to be less safe than other circuits used for high profile events. If it were not already an existing Grand Prix, it would not be permitted to be added to the Formula One schedule, for safety reasons.<ref>In the Driving Seat p. 32, Lines 8-10 Stanley Paul & Co. Ltd.

In January 2009, the circuit was voted top of the "Seven Sporting Wonders of the World" in a poll of 3,500 British sports fans.<ref>{{#if: Monaco tops Seven Sporting Wonders

A lap of the modern day circuit

The lap starts with a short sprint up to the tight St. Devote corner. This is a nearly 90 degree right-hand bend usually taken in first or second gear.<ref>Reliant Motors Formula 1 Grand Prix Annual 1995 Page 144, Line 1 Words On Sport Ltd. ISBN 1-898351-25-2</ref> This corner has seen many first lap accidents, although these are less common since the removal of the mini roundabout on the apex of the corner before the 2003 event, making the entrance to the corner wider. The cars then head uphill, before changing down for the long left-hander at Massenet.

Out of Massenet, the cars drive past the famous casino before quickly reaching the aptly named Casino Square. The cars snake down the next short straight, avoiding an enormous bump on the left of the track, a reminder of the unique nature of the circuit. This leads to the tight Mirabeau corner, which is followed by a short downhill burst to the even tighter Loews Hairpin. It is a corner which has been used for many overtaking manoeuvres in the past. However it would be almost physically impossible for two modern F1 cars to go round side by side, as the drivers must use full steering lock to get around. It is so tight that many Formula 1 teams must redesign their steering and suspension specifically to negotiate this corner.

After the hairpin, the cars head downhill again to a double right-hander called Portier before heading into the famous tunnel, a unique feature of a Formula One circuit. (Until 2009 only one other circuit, Detroit USA in 1982-88, featured a tunnel, but the F1 series now includes racing at the Yas Marina Circuit in Abu Dhabi, which presents a shorter tunnel at the exit of the pit lane.) As well as the change of light making visibility poor,<ref name=Seat>In The Driving Seat, Page 42</ref> a car can lose 20-30% of its downforce due to the unique aerodynamic properties of the tunnel.<ref name=Seat/>

Out of the tunnel, the cars have to brake hard for a tight left-right chicane. This has been the scene of several large accidents, including that of Karl Wendlinger in 1994, and Jenson Button in 2003. The chicane is probably the only place on the circuit where overtaking can be attempted. There is a short straight to Tabac, a tight fourth gear corner which is taken at about 195 km/h (120 mph).<ref name=Driving>In The Driving Seat Page 43</ref> Accelerating up to 225 km/h (140 mph),<ref name=Driving/> the cars reach Piscine, a fast left-right followed by a slower right-left chicane which takes the cars past the swimming pool that gave its name to the corner.

Following Piscine, there is a short straight followed by heavy braking for a quick left which is immediately followed by the tight 180 degree right-hander called La Rascasse. This is another corner which requires full steering lock; it will be remembered for a long time as the location of one of the most suspicious maneuvers in recent Formula One history after the 2006 season when Michael Schumacher appeared to deliberately stop his car in qualifying so as to prevent Fernando Alonso and Mark Webber — who were both following and were on flying laps — from out-qualifying him. The Rascasse takes the cars into a short, adversely-cambered, straight that precedes the final corner, Virage Antony Noghes. Named after the organiser of the first Monaco Grand Prix, the corner is a tight right-hander which brings the cars back onto the start-finish straight, and across the line to start a new lap.

Mechanical adaptations

Monaco's street circuit places very different demands on the cars in comparison to the majority of the other circuits used during a Championship season. The cars are set up with high downforce, not as is popularly believed to increase cornering speeds, as many of the corners are taken at such a low speed to negate any aerodynamic effect, but instead to shorten braking times and keep the cars stable under acceleration.<ref>http://www.formula1.com/news/features/2009/5/9363.html [aerodynamics section]</ref> Many teams use special wing assemblies incorporating extra active planes in addition to those in use for other circuits. The Jordan and Arrows teams tried to use new mid-wings in 2001. The Arrows wing was similar in design to a normal rear wing, but smaller and suspended above the nose cone. Jordan had a small wing suspended on a short pole just in front the driver. Both were designed to improve downforce, but, after testing them during Friday practice, the FIA banned both.

Brake wear is not a problem during a race in Monaco. Instead the low speeds mean the issue is keeping the brakes up to working temperature. The only heavy braking points are at the chicane after the tunnel, and to a lesser extent into the Ste Devote and Mirabeau corners. With a lack of temperature brake bite becomes a problem, as the surface of the carbon brake disc becomes smooth as glass, reducing friction between the pads and the disk, hence lessening braking power. To combat this, in 2006 Juan Pablo Montoya adopted discs with radial grooves that increase the bite rate between disk and pads, increasing the average temperature of the brakes.

Conversely, cooling the cars' engines is a major concern. Formula One cars do not incorporate any form of forced cooling, relying solely on air moving over the car to remove heat from the radiator elements. In the past many teams used to adjust the radiator intakes to allow for extra airflow, creating the once-common "Monaco nose". Teams also use a closer ratio gears, as there are hardly any long straights in Monaco and acceleration is at a premium. Some Formula One teams use other specifically designed components for this circuit.
