Kwasniewski, 18, will make his series debut in the season opener at Daytona International Speedway on February 22.
"I'm thankful for Harry Scott and Steve Turner for giving me this opportunity, as well as Rockstar for moving up with us," Kwasniewski said. "The test session earlier this month at Daytona taught us a lot and it's good to enter Daytona with a level of confidence. Racing in the Nationwide Series is going to present a lot of challenges and it won't be easy, but I look forward to taking it all on, learning from the other competitors and hopefully winning some races."
Kwasniewski, a native of Las Vegas, will bring Rockstar Energy Drink with him to the Nationwide Series. Rockstar, headquartered in Las Vegas, has partnered with Kwasniewski since 2009.
"Everyone at Rockstar is proud of the investment we have made in Dylan Kwasniewski," Jason May, executive vice president marketing for Rockstar Energy Drink stated. "He has demonstrated that he has the potential to become one of the best drivers on the planet and his transition into the NASCAR Nationwide Series at such a young age is proof of that. Rockstar is fortunate to be aligned with such a strong brand ambassador with an incredibly bright career in front of him."
Kwasniewski made his TSM debut last season and became the first driver ever to capture both the K&N East and West championships. In 14 starts, he earned six wins, eight top-five and 10 top-10 finishes, three poles and led 394 laps. He also was selected for the NASCAR Next program, an initiative to spotlight the sport's up-and-coming stars, for the second-consecutive year.
"Dylan is a great kid and has unbelievable talent," Harry Scott Jr. said. "Steve and I are thrilled that he is taking the next step in his career with us here at TSM. The sky is the limit for Dylan and this Rockstar team. He showed us what he's capable of last year and while he's making a big step, we know Dylan can achieve great things this year."
The Rockstar Energy Drink team will be led by veteran crew chief Pat Tryson. Tryson first joined TSM in August 2013 as crew chief for Nelson Piquet Jr. In 527 combined NASCAR Sprint Cup, Nationwide and Camping World Truck events, he has led his teams to 10 wins, 66 top-five and 141 top-10 finishes and four poles.
Before competing in his first-ever Nationwide Series race next month, Kwasniewski also will compete in the ARCA Racing Series Lucas Oil 200 at the 2.5-mile superspeedway on Saturday, February 15.
