The Chevrolet Cruze 1.6Ts continue to be the benchmark cars, retaining their 40 kg maximum ballast to set them at 1,190 kg. The Honda Civic WTCCs gained 10 kg after their strong showing in the United States to take them up to 1,170 kg. The Honda of Takuya Izawa was set at the base weight of 1,150 kg on its first appearance of the season, this was the test car previous used by Tiago Monteiro in 2012 which was homologated under 2012 Scandinavian Touring Car Championship regulations. Both the SEAT León WTCCs and BMW 320 TCs dropped to the minimum weight of 1,130 kg, the same as the Lada Granta WTCCs. The Chevrolet Cruze LTs and the BMW 320sis making their first appearances of the season started on the base weight of 1,150 kg.[3]
Muller led Pepe Oriola at the end of the first test session on Friday which saw a number of red flags. Souza spun his China Dragon Racing Chevrolet at turn eight, Mikhail Kozlovskiy was the next to get stuck in the gravel while Norbert Michelisz put his Zengő Motorsport Honda also ended his session in the gravel traps.[12]
Monteiro headed a Honda 1–2 in free practice one with Izawa second fastest, championship leader Muller was third. Marc Basseng was black flagged having been towed out of the gravel trap at Turn 8.[13]
Muller was on top in free practice two, Alex MacDowall was second having led the session earlier on. Tom Chilton had a near–miss with his RML teammate and had to go off the track onto the grass to avoid collecting Muller.[14]
Qualifying
The four Honda cars led by Gabriele Tarquini were the first out on track at the start of Q1. Chilton was fastest earlier on in the session with MacDowall third. Monteiro went to the top of the times 8 minutes in before he was deposed by the fellow Honda of Michelisz. Muller moved to the top of the times with 3 minutes remaining, James Thompson moved into the top 12 at the expense of Charles Ng. Izawa was outside the top 12 and made a last attempt to get through to the second part of qualifying but a trip out onto the grass meant he failed to improve his time, ensuring Robert Huff in 12th was safely through to the next session.
Early on in Q2, Michelisz led the RML drivers in the times while Thompson opted not to go out straight away. At the halfway point of the session all the drivers were it the pit lane, Oriola and MacDowall went out before Thompson went out for the first time with just under four minutes left of the session. Oriola looked to be setting a quick lap but failed to improve in the last sector, MacDowall went up to second with Thompson on his first timed lap did not improve from 12th. Muller had a slide at turn one while Tarquini went off a Turn 3 and narrowly avoided the tyre wall. At the end of the session Michelisz stayed on top to secure his first pole position of the season, MacDowall in second was the best placed independent driver while Mehdi Bennani finished tenth to take pole for race two.[15]
Warm-Up
Michelisz was fastest in the warm–up session on Sunday morning with Monteiro second.[16]
Race One
Michelisz got away from pole position well to keep MacDowall behind him while Monteiro leapt up to third. At the end of the first lap Monteiro attempted to pass MacDowall but ran wide and dropped back behind the RML cars. On lap 4 Pepe Oriola tapped the back of Tarquini, as the Honda driver tried to regain control Nash went up the inside and moved up ahead of Oriola. Lap 8 saw Yoshimoto run wide at Turn 1. At half distance, Michelisz had built up a healthy lead over MacDowall who had the close company of Muller and Chilton; there was a gap to the rest of the field behind them led by Tarquini. Monteiro was right behind Oriola on lap 19 and trying to take seventh place, he tapped the back of Oriola who recovered but then Monteiro tried to go up the inside of Oriola at Turn 7, crashing into the tyre stack on the apex. At the same time Tarquini went off the track with a left–front puncture which released Nash into fifth place. Monteiro went into the pits for repairs as Oriola was issued with a drive–through penalty for squeezing Monteiro off the track. Oriola failed to serve his penalty; he returned to the pits where he retired his car. Michelisz claimed the victory while MacDowall held on to second after defending from Muller and Chilton on the last lap. Muller secured his fourth World Drivers' Championship title with third place.[17]
Race Two
Bennani lined up on pole position for the 200th race in the history of the WTCC. Bennani held the lead while contact further back between Michelisz and Muller flung Muller off into the wall and out of the race, Michelisz suffered a broken front left suspension. The incident left polystyrene on the pit straight. With the yellow flags out in the first sector, overtaking opportunities were limited as the leading pair of Bennani and Coronel pulled away from the Hondas of Tarquini and Monteiro. Tom Boardman tried an overtake up the inside of Kozlovskiy at Turn 1, Kozlovskiy was tapped and ran wide and Boardman went through. Coronel also tried a move on Bennani at the first corner shortly after and then again on lap 10 with no success. Mak went off into the gravel in the second sector while Monteiro got past his teammate. On lap 13 Kozlovskiy and Oriola were issued with drive–through penalties for jump starts. Charles Ng was defending from Robert Huff who made a move on the pit straight and went onto the grass to complete the move into the first corner. On lap 17 Coronel went into the lead, passing Bennani at the first corner when the Proteam Racing driver ran out wider than usual. Two laps from the end, MacDowall went off at Turn 1 and dropped from 9th to 13th when he returned to the track. Coronel claimed his third victory in Japan, Bennani was second and the independent winner.
After the race, Basseng was given a 30–second penalty for a move on Thompson, which dropped him out of the points to 12th.[18]
