Wittmer was born from a racing family, preceded by his grandfather, father, and uncle competing in local rallying events in their home province of Quebec. Wittmer received his first ATV at age three, before competing with both ATVs and in motocross at the age of seven. When Wittmer was 15, he attended a racing school at Circuit Mont-Tremblant, beginning his circuit racing career.[2]
In 1999, he began competing in the Canadian Formula Ford Championship, and claimed the series' Rookie of the Year honors at season's end.[3] A brief stint in the Atlantic Championship followed, before Wittmer returned to Formula Ford competition and karting in Quebec over the next few years.[4] In 2002, Wittmer secured his first career championship title in the Quebec Sedan GT Championship.[5] A year of Formula Renault competition followed, before Wittmer transitioned to touring car competition in 2004 with Canada's Honda Michelin Challenge. He won the championship in 2005, taking five wins and six total podiums nine races.[5]
Touring car competition (2006–2009)
In 2006, Wittmer began competing in the Pirelli World Challenge, continuing his relationship with de Sigi Autosport, the team with whom he'd competed in the Honda Michelin Challenge over the past two seasons. After a quiet first season, Wittmer linked up with RealTime Racing for 2007, competing with the team he had "been looking up to since the age of 15." He scored a TC-class pole position on home soil at Toronto, and scored his sole podium during the final round of the season at Laguna Seca.[6] He finished third in the championship behind Jeff Altenburg and Randy Pobst.[7] Wittmer also supplemented his 2007 campaign with a part-time drive in the then-Koni Sports Car Challenge for Georgian Bay Motorsports.
Wittmer returned to RealTime in 2008, and would claim his first career World Challenge victory during the TC class' second round of the season at VIR. He would claim two further race victories, at Lime Rock and Mid-Ohio,[8] and finished the season with five total podiums to his name. The season concluded with another third-place championship finish for Wittmer. He also stepped up to a full-time drive in the Koni Sports Car Challenge's ST class, finishing third in the championship for the i-Moto team. Wittmer embarked on his final TC season in 2009, returning to the RealTime stable for the third consecutive season. He scored just one victory that season, on home soil at Mosport,[9] en route to a sixth-place championship finish.
Wittmer began his relationship with Dodge in late 2009, when he took on a one-off World Challenge drive for Woodhouse Performance in the GT class. The following year, Wittmer began competing full-time in the GT class, driving an SRT Motorsports-prepared Dodge Viper Competition Coupe. After finishing sixth and fifth in the double-header at St. Petersburg, Wittmer claimed his maiden GT-class victory during the ensuing round at Long Beach, leading lights-to-flag and setting a new track record during qualifying.[10] Wittmer followed that up with a second-place finish during the next round at Mosport,[11] but would be forced to wait until the final round of the season at Utah Motorsports Campus to return to victory lane. He finished the season runner-up in the GT class, just under 200 points behind Pobst.[12]
Wittmer shifted to a test driver role for 2011, in advance of the LM GTE-class SRT Viper GTS-R program coming online in 2012. Wittmer completed a one-off drive in the ADAC GT Masters series,[13] as well as taking on a single race in the one-make Dodge Viper Cup. Later that year, he set a production car lap record at Utah Motorsports Campus in a Dodge Viper ACR,[14] and worked with the SCCA to develop technical regulations for its new B-spec regulations for 2012.[15]
Wittmer made his American Le Mans Series debut at Mid-Ohio in August 2012, giving the GTE-class Viper its first outing in official competition.[16] Wittmer's #91 entry, which he shared with Dominik Farnbacher, finished tenth on debut.[17] Another top ten followed at Road America, before the team registered their season-best finish of eighth at Petit Le Mans.[18]
The program expanded to a full-time effort in 2013, as Wittmer jumped to the #93 car alongside Jonathan Bomarito for the full season, with Tommy Kendall joining for the endurance rounds.[19] In January, it was confirmed that the program would make its debut at the 24 Hours of Le Mans that year, marking the Viper marque's return to the race for the first time since the early 2000s.[20] Wittmer remained entered in the #93, marking his own debut at the event, which he called "a dream come true."[21][22] After starting 11th in GTE Pro,[23] Wittmer's entry came home ninth in class, five laps behind the sister #53 entry and 14 laps behind the class-winning Porsche 911 RSR.[24]
After a quiet start to the ALMS season, which saw Wittmer and Bomarito finish no higher than sixth in class over the first four races, Wittmer's home race at Mosport provided the entry's first podium finish of the season. After starting on pole at the hands of Bomarito, the duo finished third in class behind the sister car and the race-winning #4 Corvette.[25] Bomarito took pole for the next race at Road America,[26] but the entry would fade to a sixth place finish. Wittmer claimed his second and final ALMS podium later that season at COTA, where the #93 finished second in class.[27] At the end of the season, Bomarito and Wittmer were classified ninth in the GT class championship.
Ahead of 2014, Wittmer's FIA Driver Categorisation ranking was downgraded from Platinum to Gold.[28] This came despite a continuation of his factory drive with SRT Motorsports, as he returned for the full United SportsCar Championship campaign with the team, joined again by Bomarito for the full season.[29] After a sixth-place finish at Daytona, Wittmer came up just short of his first victory at the 12 Hours of Sebring, placing second.[30] He returned to the podium at Watkins Glen, claiming a third place finish. As such, the following round at Mosport carried particular weight for Wittmer, as he felt the team was poised for a breakthrough victory in the championship.[31] He claimed pole in GTLM,[32] and would finish the race second behind the #3 Corvette.[33]
Shortly thereafter, Wittmer took part in a one-off Pirelli World Challenge appearance to mark the launch of the Viper GT3 customer racing program at Toronto.[34] He finished second overall on Saturday, and scored the race victory on Sunday.[35]
Wittmer claimed his maiden IMSA victory at Indianapolis in late July, the first of the year for SRT Motorsports.[36] Following another podium at Road America and a fifth-place at VIR, Wittmer returned to victory lane as part of a Viper 1-2 at COTA.[37] With both Bomarito and Wittmer in contention for the drivers' title at Petit Le Mans, the duo were split for the championship decider, with Wittmer drafted into the #91 alongside Marc Goossens and Ryan Hunter-Reay.[38] A podium finish for the #91 was enough for Wittmer to secure the title, making him the inaugural United SportsCar Championship GTLM champion.[39]
Less than 48 hours after his title was confirmed, Chrysler shuttered the factory-backed Viper program for 2015, leaving Wittmer without a ride.[40]
Later career
Prior to the 2020 Michelin Pilot Challenge season, Wittmer joined AWA Racing's McLaren entry in the Grand Sport class.[41] Wittmer took pole in his first race with AWA, with a half-second advantage over Tyler McQuarrie in second.[42]
In August 2023, Wittmer announced his official retirement from professional racing.[43]
