Preview

The 6 Hours of Circuit of the Americas was confirmed as part of the FIA World Endurance Championship's 2014 schedule in an FIA Endurance Commission meeting in Paris in January 2014.

An agreement was reached by circuit officials, the Automobile Club de l'Ouest (ACO) and International Motor Sports Association (IMSA) to run the race on the Saturday. WEC used the Circuit of the Americas' 20-turn Grand Prix layout.

The minimum weight of the LMP1 privateer cars was reduced to from the Le Mans limit of as the CLM P1/01 and Rebellion R-Ones received a four percent increase in maximum fuel flow rate and a fifteen percent break in fuel energy per lap to increase their performance. In the LMGTE category the commission added an additional of ballast to the Aston Martins to lower their performance.

Practice

There were three practice sessions—one 90-minute session each on Thursday afternoon and evening and a one-hour session on Friday afternoon—preceding Saturday's race. The first practice session took place in overcast and cool weather conditions. The No. 2 Audi R18 e-tron quattro driven by Fässler led with the fastest lap time of the day, at 1 minute and 51.136 seconds, one-tenth of a second quicker than teammate Kristensen in second whose best lap was recorded late in the session. Brendon Hartley's No. 20 Porsche 919 Hybrid was third-fastest after leading the session in its opening minutes and both Toyota TS040 Hybrids rounded out the top five in LMP1-H. Davidson stopped his car near the exit of pit lane in the closing minutes of the session with a systems problem but continued after he restarted his vehicle. Olivier Pla was first to lead LMP2 but Dalziel ended as the fastest driver with a lap of 1 minute and 58.111 seconds. Pla fell to second and Howson was third. Darren Turner's No. 97 Aston Martin was the quickest car late on in LMGTE Pro while Stanaway helped the British marque to be fastest in LMGTE Am.

The second practice session was delayed for an hour because of an electrical thunderstorm that caused localised flooding around the circuit and it also prevented trackside marshals from taking up their posts due to local bylaws governing safety. Once the rain had abated enough to allow for cars to circulate the track, the session commenced and several drivers reported aquaplaning over the multiple heavy puddles that had formed on the circuit. The first red flag came out after seventeen minutes when Rigon beached the No. 71 AF Corse Ferrari off course between turns 17 and 18. The car was recovered back to the pit lane. After the restart, the rain let up and Davidson's No. 8 Toyota recorded the best lap of the session with a time of 2 minutes and 1.333 seconds. Kristensen placed the No. 1 Audi in second and Wurz's No. 7 Toyota was third. In LMP2, the No. 47 KCMG of Bradley was fastest with a time of 2 minutes and 17 seconds. Makowiecki topped the LMGTE Pro time sheets in Porsche Team Manthey's No. 92 and the No. 95 Aston Martin of Stanaway paced the LMGTE Am category.

In the final practice session, Kristensen put the No. 1 Audi at the top of the time sheets and Duval improved on his co-driver's form with a lap of 1 minute and 49.480 seconds. The No. 2 Audi of Fässler was second fastest and Toyota's No. 8 car of Davidson was third. The fastest Porsche was fourth courtesy of a lap from Neel Jani's No. 20 entry. Pla in the No. 26 was again the fastest driver in LMP2 with a lap of 1 minute and 56.601 seconds, eight-tenths of a second faster than Bradley's No. 47 KCMG vehicle. In LMGTE Pro, Aston Martin's No. 99 Vantage driven by Fernando Rees was quickest by four-hundredths of a second from the sister No. 97 entry of Stefan Mücke. Aston Martin was also the fastest manufacturer in LMGTE Am with Pedro Lamy's No. 98 Vantage from Paolo Ruberti in second place, driving the No. 90 8 Star Motorsports Ferrari.
