Round 1: St. Petersburg

Takuma Sato sat on the pole, but he lost the lead at lap 30 to Will Power. On a restart on lap 82, leader Will Power was bringing the field back to green when an "accordion effect" saw the field check-up on the main stretch. Marco Andretti and rookie Jack Hawksworth made contact and crashed into the inside barrier.

Power led the most laps, and held off Ryan Hunter-Reay and Hélio Castroneves for the victory. Polesitter Takuma Sato finished 6th.

Round 2: Long Beach

On lap 56, a controversial crash took out six cars, including the drivers running 1st–2nd–3rd. During a sequence of green flag pit stops, Josef Newgarden inherited the lead. Ryan Hunter-Reay, James Hinchcliffe, and Will Power were running nose-to-tail in 2nd–3rd–4th. Newgarden completed his pit stop, and came out on the track just ahead of Hunter-Reay, momentarily holding on to the lead. Going into turn 4, Hunter-Reay attempted a risky pass for the lead, and he made contact with Newgarden, sending both cars into the wall. Hinchcliffe was collected, as was three other cars in the huge melee that nearly blocked the track.

Late in the race, Scott Dixon led, followed by Mike Conway and Power close behind. Dixon ran out of fuel, and had to pit with two laps to go. Part timer Conway held off Power and Munoz to win his second Long Beach Grand Prix.

Round 3: Barber

Heavy rain and lightning delayed the start of the race. Will Power took the lead at the start and led the first 15 laps. But he spun out in the turn 5 hairpin on lap 16, giving up the lead to Ryan Hunter-Reay. Hunter-Reay went on to lead 40 of the race's 69 laps and ultimately won the race; two weeks after creating a stir and raising tempers around the paddock at Long Beach.

Due to the late start, the race was changed to a 100-minute timed race but finished under caution when rookie Mikhail Aleshin had a heavy crash into the tire barriers, littering the track with debris.

Round 4: Grand Prix of Indianapolis

The month of May at Indianapolis opened with the Inaugural Grand Prix of Indianapolis on the Speedway's road course. With the field lined up for a standing start, polesitter Sebastián Saavedra's car stalled. A huge crash resulted, involving Saavedra, Carlos Muñoz, and Mikhail Aleshin, showering debris along the frontstretch and into the pit area.

Late in the race, Simon Pagenaud led Ryan Hunter-Reay. Both drivers were low on fuel, and trying to nurse their cars to the finish. Hélio Castroneves, who had pitted for fuel, was charging through the field, and looking to run down the leaders. Pagenaud held off the challenge, and crossed the finish line just ahead of Hunter-Reay and Castroneves. Pagenaud's car ran out of fuel on the cool down lap. Series rookie Jack Hawksworth, who earned his first front-row start, led a field-high 31 laps and finished seventh.

Round 5: 98th Indianapolis 500

Indianapolis resident and now oval only driver Ed Carpenter won the pole position for the 98th Indianapolis 500.

The race started with a long green flag run of 149 laps. Charlie Kimball and Scott Dixon suffered single-car crashes, then James Hinchcliffe and Ed Carpenter tangled on a restart. The red flag halted the race with 9 laps to go for a crash involving Townsend Bell. After the restart, Ryan Hunter-Reay and Hélio Castroneves dueled for the win, followed closely Marco Andretti. Hunter-Reay won the race by 0.06 seconds, the second closest finish in Indy 500 history.

Round 6: Detroit (Sat.)

Will Power took the lead with 11 laps to go, and held off Graham Rahal over the final 10 laps to win Race 1 of the Dual in Detroit. Indy 500 winner Ryan Hunter-Reay finished 16th after he spun into a tire barrier on the last lap.

Round 7: Detroit (Sun.)

Hélio Castroneves won Race 2 of the Dual in Detroit, sweeping the weekend for Team Penske. Will Power finished second, charging from the back of the pack after an early drive through penalty. After spinning out a day earlier, Ryan Hunter-Reay had another bad day, dropping out with electrical problems.

Round 8: Texas

During the final round of pit stops – on lap 213 of 248 – Ed Carpenter and Will Power were running first and second, but Power was penalized for speeding as he entered the pit lane. After a drive-through penalty, Power dropped to sixth. A late caution on lap 241 bunched the field and allowed Power to close in. Carpenter and second place Juan Pablo Montoya stayed out during the yellow to maintain their track position, but Power and others chose to pit for new tires. The green came out with two laps to go, and Carpenter got the jump on the restart. With fresh tires, Power charged through the traffic, passing Montoya for second in the final corner, and just held him off as Carpenter cruised to the victory.

Round 9: Houston (Sat.)

Colombian drivers Carlos Huertas, Juan Pablo Montoya, and Carlos Muñoz swept the podium in the first race of the Houston doubleheader. Rain soaked the race, which was shortened from 90 laps to a timed race of 1 hour and 50 minutes. Huertas took the lead with about seven minutes remaining. Under a late caution, the field was coming to a restart with one lap to go. Fourth place Graham Rahal ran into the back of third place Tony Kanaan, sending Kanaan spinning. Muñoz was promoted into third after Rahal received a 30-second time penalty post-race for avoidable contact. Huertas' victory marked the first time a rookie had won an IndyCar race since Rahal at the 2008 Honda Grand Prix of St. Petersburg.

Round 10: Houston (Sun.)

Simon Pagenaud led the final 43 laps to win the second race of the Houston doubleheader, for his second victory of the season. Pagenaud's teammate, rookie Mikhail Aleshin, finished second giving Schmidt Peterson Motorsports its first 1–2 finish in IndyCar competition. Points leader Will Power was running third in the closing laps, but a broken suspension with less than two laps to go, dropped him to 11th at the finish.

Round 11: Pocono

Juan Pablo Montoya, who returned to Indy car racing after six seasons in Formula One and seven seasons in NASCAR, won his first Indy car race since the 2000 CART season. Montoya led a total of 45 laps, and assumed the lead for the final time with three laps to go. In the closing laps, most of the leaders needed one final pit stop for fuel, but both Josef Newgarden and Tony Kanaan tried to stay out and gamble for a late yellow. Neither were able to make it to the finish, and Montoya assumed the lead when Kanaan ducked into the pits on lap 197.

Montoya's Penske teammate Hélio Castroneves finished second, and left the race in a tie for the points lead with Will Power. Power led 69 laps, and was in the lead group, but two blocking incidents – the first clipping off Montoya's wingplate, and the second a double move on Castroneves – earned him a drive-through penalty and took him out of contention. The race went caution-free for the first 158 laps, with the only incident a spin by Graham Rahal exiting the tunnel turn. The average speed of 202.402 miles per hour (325.734 kilometres per hour) set the record for the fastest 500 mile race in Indy car history.

Round 12: Iowa

Tony Kanaan dominated the race, leading 247 laps, but Ryan Hunter-Reay took the victory, after passing Kanaan with two laps to go. With Kanaan leading and Ganassi teammate Scott Dixon running second, Juan Pablo Montoya tangled with Ed Carpenter on lap 281, bringing out the final caution. Montoya accused Carpenter of turning down on him while he was attempting a pass in turn three. Carpenter, who was suffering handling difficulties, admitted to taking a low line, but officials did not issue a penalty for the incident.

With under 20 laps to go, Kanaan stayed out on the track under the yellow, while Hunter-Reay, Josef Newgarden, and a handful of other cars pitted for fresh tires. When the green came back out, Hunter-Reay quickly charged through the field, and took the lead with two laps to go. Newgarden followed suit, climbing up to second. Kanaan's loss was the latest in a series of disappointments in 2014. Power fell from 4th to 12th during the final six laps after brushing the wall, which caused a tire to lose air pressure.

Round 13: Toronto (Sat. & Sun.)

The first race of the Toronto doubleheader was scheduled for Saturday afternoon. Rain and standing water on the course prompted officials to postpone the race until Sunday morning. Sébastien Bourdais won his first Indy car race since 2007, and his first as part of the IndyCar Series.

Round 14: Toronto (Sun.)

The second race of the Toronto doubleheader was held late Sunday afternoon. Mike Conway was the winner. Tony Kanaan had two podium finishes on the same day. He finished third in the morning race and second to Conway in this race.

Round 15: Mid-Ohio

Scott Dixon won at Mid-Ohio for the fifth time in eight seasons. Dixon became the tenth different winner in 2014, and the race was the first win of the season for Ganassi Racing. Polesitter Sébastien Bourdais led the early stages of the race, and Dixon, who started last after spinning out during qualifying, worked his way to the front off-sequence in pit stops from the other leaders. Dixon capitalized on an error by Josef Newgarden during his final pit stop. Newgarden ran over an air hose, tripping a crew member, and was penalized for hitting pit equipment. Tony Kanaan suffered another disappointment, spinning out in the first turn after nearly tangling with other cars at the start. He spun around, and collected Marco Andretti.

The points leader going into the race, Hélio Castroneves, suffered throttle problems on the grid, and joined the race four laps down, and finished a lowly 19th. Will Power departed the race as the new points leader by four points over Castroneves. Third in the standings, Ryan Hunter-Reay, was unable to make up much ground in the championship race after a penalty for speeding in the pits, and later spinning out into the tire barrier.

Round 16: Milwaukee

Polesitter Will Power dominated the race, leading 229 of 250 laps, taking the victory, his first at Milwaukee. Mired in heavy traffic over the final several laps, Power was able to maintain a two-second lead over teammate Juan Pablo Montoya, who came home second. Tony Kanaan, among the leaders most of the afternoon, rounded out the podium in third place — still win-less on the season. Power departed with a 39-point advantage over Hélio Castroneves in the championship standings with two races remaining.

Round 17: Sonoma

The morning of the race, an earthquake occurred in the region, but did not alter the schedule for the race. Polesitter and points leader Will Power jumped out to the lead at the start. In turn two, points contender Hélio Castroneves, was involved in a multi-car tangle, requiring a lengthy pit stop for repairs. Power led early, but later suffered a spin in turn seven, and eventually wound up finishing 10th.

Mike Conway passed Tony Kanaan on a restart on lap 40, and led for 19 laps. Towards the end of the race, the leaders were trying to stretch their fuel to the finish. With Conway in conservation mode, Graham Rahal came to the lead, with Scott Dixon and Ryan Hunter-Reay now running third and fourth. Rahal was forced to the pits with three laps to go, handing the lead back to Conway. Going into turn one, Scott Dixon blew by Conway for the lead, and won his second race of the season. Conway ran out of fuel and finished 14th.

Will Power stretched his lead over Hélio Castroneves in the championship standings to 51 points. With one race remaining, four drivers were mathematically in contention for the title; Will Power, Hélio Castroneves, Simon Pagenaud, and Ryan Hunter Reay. Power could clinch the championship by finishing sixth or better at Fontana.^[52]

Round 18: Fontana

The season concluded with the MAVTV 500 at Auto Club Speedway. Double points were awarded, per new rules for all 500-mile events. Four drivers started the race mathematically alive for the title; Will Power, Hélio Castroneves, Simon Pagenaud, Ryan Hunter Reay. Very early in the race, Pagenaud was forced to make unscheduled pit stops due to handling problems, and quickly was out of the title picture. The championship at that point became a three-man battle between Will Power, Hélio Castroneves, Ryan Hunter Reay.

Juan Pablo Montoya led much of the early going, with both Power and Castroneves holding steady in the top ten most of the day. The race was slowed by only one yellow, caused by a spin on lap 175 involving Ryan Hunter-Reay, after that it came down to a two-man race for the championship between Penske teammates Will Power and Hélio Castroneves. Scott Dixon finishes the season 3rd in points, 67 points out of the lead. Juan Pablo Montoya finishes the season 4th in points, 85 points out of the lead. Tony Kanaan finally got his first win of the season, after so many losses, he gets his first since the 2013 Indianapolis 500. With Kanaan comfortably in the lead, the championship battle between Power and Castroneves came down to the final 30 laps. As the leaders cycled through their final green flag pit stops, Castroneves was penalized for an improper entry into pit lane. He was assessed a drive-through penalty, and fell a lap down. Power was able to cruise to the finish line, and his ninth-place finish clinched the drivers' championship title. For the second year in a row, Castroneves finishes the season runner-up and comes home 62 points out of the lead.
