Ryan Sieg

In 2019, Sieg returned to the Truck Series for the JEGS 200 at Dover, driving the No. 33 Chevrolet for Reaume Brothers Racing. After starting last in 32nd, he finished 16th.

In September 2019, Sieg finished 14th in the Rhino Pro Truck Outfitters 300 at Las Vegas, but was disqualified after his car failed post-race inspection for not meeting the minimum ride height. Nevertheless, he qualified for the Xfinity playoffs and the disqualification did not affect his points standing.

On January 24, 2018, Sieg announced another full season with RSS Racing. After a sixth-place run at Talladega Superspeedway in the spring, Sieg qualified for the Xfinity Series Dash 4 Cash at Dover International Speedway after Spencer Gallagher's eligibility was stripped. A pit road penalty during the race prevented Sieg from making it any farther in the D4C. Sieg's efforts received a boost in 2018 with the addition of two start and park cars that RSS Racing also fielded to help fund Sieg's efforts in the No. 39.

On December 27, 2018, Sieg announced another full Xfinity season with RSS Racing, with the goal of making the playoffs for the first time since 2016. After scoring his second top-five of the year at the spring Richmond Raceway event, Sieg sat ninth in the point standings. He credited new crew chief Shane Wilson and new cars from Richard Childress Racing as catalysts for the uptick in performance.

In June 2017, Sieg recorded his best career Xfinity finish of second at Iowa Speedway. Later in the season, Sieg's Xfinity throwback car for Darlington Raceway honored Ryan's brother Shane Sieg, who had died two weekends prior.

In May 2017, Sieg was signed by BK Racing to drive their No. 83 Toyota Camry in the Monster Energy NASCAR Cup Series at Dover International Speedway for the AAA 400 Drive for Autism, his MENCS debut. A month later, he replaced Gray Gaulding in BK's No. 23 Camry for the FireKeepers Casino 400 at Michigan.

In 2015, Sieg returned to the Xfinity Series with new sponsor Uncle Bob's Self Storage at the season opener at Daytona. He finished 38th after being involved in the first big one. Sieg had a consistent season with finishing many races under 20th, including an 8th-place finish at Kansas, finishing 11th in points. Sieg lost the sponsorship from Uncle Bob's for 2016 but a number of sponsors filled the void. Some highlights of the season included almost qualifying for the Dash 4 Cash at Dover International Speedway, running in the top five at Daytona International Speedway, and qualifying for the inaugural Xfinity Series Chase before being knocked out after the first round.

In February 2014, RSS Racing announced that Sieg would run the full Truck Series season and at least the first five Nationwide Series races in 2014. He finished in the 9th spot in the season-opening DRIVE4COPD 300 at Daytona International Speedway, his first top 10 in the Nationwide Series. After Fontana, it was announced that Sieg would focus his efforts on the Nationwide Series for the remainder of the season, running for Rookie of the Year. Sieg then earned fame himself at the July race at Daytona when he drafted Kasey Kahne past teammate Regan Smith to his first Nationwide victory since 2007. In doing so, he also scored his first career top 5 finish with a 3rd-place finish, enough to put him in the first of four races in the 2014 Nationwide Dash 4 Cash event the next week at New Hampshire. Sieg was rather impressive in 2014, having some other solid runs to go along with the two top 10s to finish the season 16th in points.

Season still in progress Ineligible for series points Sieg started the 2014 season running for Truck Series points but switched to Nationwide before Fontana.

In 2013, in addition to running the full Camping World Truck Series season, Sieg substituted for Jeremy Clements in the NASCAR Nationwide Series during the latter's suspension. Later in the year he ran at the Indianapolis Motor Speedway in the Indiana 250 for his own team.

For 2012, Sieg led six laps at the Charlotte Motor Speedway race after staying out on a pit stop during a caution. He ran the final three laps in 3rd position before finishing in 15th after running out of fuel on the last lap at Michigan International Speedway on August 18, marking his best final-laps position in the Camping World Truck Series. He would later score a 6th-place finish at Phoenix.

On June 10, 2011, Sieg finished 7th in the WinStar World Casino 400K at Texas Motor Speedway, marking his best career finish in his 44th start in the Camping World Truck Series. He also led ten laps earlier after staying out on a pit stop. At the September 2 Truck Series race at Atlanta Motor Speedway he piloted his No. 39 RSS Racing Chevy to a 15th-place finish.

For 2010, Sieg and his brother Shane both planned to run the full Truck Series schedule in the No. 39 and No. 93 trucks, respectively. Despite having no major sponsorship, Sieg was able to run the entire season, finishing 21 of the 25 races and earning two top-10 finishes, including an 8th at Kentucky Speedway and a 9th at Dover International Speedway.

Sieg made his NASCAR debut in 2009, competing in the Camping World Truck Series Kroger 250 at Martinsville Speedway. Driving the No. 21 Dodge for GunBroker Racing, Sieg started 16th but finished 34th due to an ignition problem. At The Milwaukee Mile, he would start a partial schedule for his family-owned race team. In nine races, Ryan recorded six top-20 finishes including a finish of 9th at Gateway International Raceway.

Ryan Shane Sieg (born June 20, 1987) is an American professional stock car racing driver and team owner. He competes full-time in the NASCAR Xfinity Series, driving the Nos. 39/93 Chevrolet Camaro for RSS Racing. He is the younger brother of former driver Shane Sieg.
