SRT Motorsports and driver Kuno Wittmer will make a surprise entry into the upcoming Pirelli World Challenge Championship Series doubleheader race weekend in Toronto in a Dodge Viper SRT GT3-R that will compete in events this weekend.

Wittmer, a native of Montreal, will pilot an all-new No. 92 Dodge Viper SRT GT3-R prepared by Riley Technologies in the ninth and 10th rounds of the sports car championship on the downtown Toronto street circuit in an effort to promote the SRT Motorsports’ customer Viper GT3-R racing program.

“It’s going to be a lot of fun to have Kuno step into the Pirelli World Challenge and test his skills in the Viper GT3-R against the top class in the series,” said Ralph Gilles, CEO of SRT Motorsports, Chrysler Group LLC.

“This is a test Viper that Riley Technologies prepared and we see this race as an opportunity to showcase our customer program. We’ve had success in the series with Dan Knox taking the Viper to the winner’s circle during the Detroit race weekend and we want to continue building momentum with our Viper GT3-R program.”

Knox, who competes full-time in the World Challenge in the No. 80 Dodge Viper SRT GT3-R, ranks third in the GT-A class standings and claimed the Viper GT3-R’s first series victory in a May race on Detroit’s Belle Isle circuit.

Wittmer will compete in the World Challenge’s GT class in Toronto one week after racing at nearby Canadian Tire Motorsport Park (Mosport) for a TUDOR United SportsCar Championship event in the No. 93 Dodge Viper SRT GTS-R, his full-time ride, on July 13.

The native of Canada has tallied three podium finishes in six starts in the TUDOR Championship in 2014 and won the pole position for the Mosport race.

“I believe that the Viper GT3-R is a benchmark car across the world,” said Wittmer. “The Viper has a lot of potential and this is a great opportunity to showcase the car in the GT class.”

Wittmer previously competed in the World Challenge from 2008 to 2010 and tallied six victories in the series, including two Viper wins in Salt Lake City and Long Beach, Calif.

SRT’s Matt Bejnarowicz will serve as the lead engineer for the No. 92 Viper GT3-R entry. Bejnarowicz currently serves as the lead engineer for Wittmer’s IMSA TUDOR Viper and the pair previously worked together in the same roles in the World Challenge in 2009 and 2010.

“I spent a lot of time in the World Challenge as a race engineer and for me it’s like going back home,” said Bejnarowicz. “That’s where Kuno and I met and he had a lot of talent and potential. We ended up getting paired up, cut our teeth together and we’ve been together since. It will be like the old days – a lot of fun and we’re going to try to put the Viper up front.”

The Toronto race weekend is the only scheduled appearance for Wittmer and the No. 92 Viper GT3-R entry in the World Challenge. Knox will continue to run the full series schedule in pursuit of the GT-A class championship for Lone Star Racing and the Viper GT3-R racing program.

“Since his first race with us in 2006, we have enjoyed watching Kuno race. We look forward to seeing him racing on the Toronto street course,” said Scott Bove, president and CEO for Pirelli World Challenge/ WC Vision.
