A well thought-out track, with some properly demanding corners not far from one of the coolest small cities in America adds up to a winning combination for all concerned.
The steep rise up to Turn One is unique, the sweepers through Turns Three and Nine pose a challenge similar to - if not quite as extreme as - Silverstone's Becketts, and after a fiddly 'stadium' section, the penultimate corner, Turn 19, is a tricky, downhill, off-camber left that always provides action.
An intimate paddock and gorgeous Texas skies add the final ingredients for an event that is hard to fault. The only cloud on the horizon is the forthcoming return of the Mexican Grand Prix. Twinned with Austin next year, how many of the Texas track's spectators will it take away, and at what cost to the US Grand Prix's viability? |
Circuit Layout
The Circuit of the Americas, which runs anti clockwise, is a wonderful mixture of many of the most famous circuits on the F1 calendar; it has more corners at over 250 km/h than Spa and more below 100kph than Hungary, which is quite a combination!
It has one very long straight with a hairpin at either end. There were a total of 55 overtaking moves during the 2012 race, but only 18 in the 2013 edition.
Austin: On board with Lewis Hamilton in the Mercedes simulator!
Weather Forecast
The forecast for the weekend is for warm weather, with temperatures of 24 to 26 Centigrade.
Likely tyre performance
Pirelli tyre choice for Austin: Soft (yellow markings) and Medium (white markings) This combination has been used six times already this season.
For the last two seasons, Pirelli has brought the medium and hard tyres to Austin and it has led to one-stop strategies. This year they have gone for the soft and medium tyres, but that is because the 2014 compounds are harder than last year’s. So we could have one or two stops as the preferred strategy, Pirelli thinks two.
Tyre warm up has been a factor at this race track in the past as it can be very cool, in the mornings especially.
In the 2012 race drivers found themselves doing five lap runs in qualifying to set a fast time. The track is now three years old so the surface will have matured and there should be more grip.
The big question mark will be the difference in performance between the two compounds; we have seen some significant differences, for example in Russia the soft tyre was clearly a second a lap faster than the medium, which meant that in the first part of the race, none of the runners on the soft were in any hurry to make their pit stop for the medium. At other venues the pace difference has been closer. The main limitation is front inner shoulder wear from sliding.
Number and likely timing of pit stops
Friday’s practice session will be vital for working out whether one stop or two is the faster race strategy. The pit lane is of average length at 395m and it takes around 21 seconds to make a stop, so there is no discouragement there from making an extra stop.
A typical one stop strategy is to start on soft tyres and pit around lap 20 for a new set of medium tyres.
Two stops would mean starting on the soft tyre, taking another set of softs around lap 15 and then a set of mediums around lap 37. Alternatively, two stints on the medium tyre if the wear on the soft was marginal and the medium had good pace.
Race Strategy Briefing Updates for the week
There will be only nine teams participating in the Grand Prix after Caterham and Marussia went into administration. This means that the FIA is likely to change the format of qualifying with four cars dropping out at the end of Q1 and four cars at the end of Q2.
There is some debate about whether Vettel will take part in qualifying in Austin. He needs to take a 6th power unit and wants to take one with all the new components, which means starting from the pit lane. But the FIA is believed to have told the team that he can still use some of the other components from his original allocation of five for the season together with a new Internal Combustion engine, in which case he will have to go out and qualify on Saturday and then take a grid penalty.
