Strong Start for BimmerWorld at Sonoma


After a long but hectic off season, the BimmerWorld haulers made their way into Sonoma last week to kick off the 2022 SRO Motorsports America season. Out rolled three beautiful BMWs ready for battle, including our first entry into the world of GT3 racing, the No. 94 TACenergy / OZIUM BMW Motorsport M4 GT3 piloted by Bill Auberlen and Chandler Hull this year in the GT World Challenge America Presented by AWS series. The M4 GT3, which BimmerWorld took delivery of only the week before this race weekend, and two M4 GT4s were prepped, stickered up, and rolled through tech Wednesday afternoon. Drivers made last-minute checks to their seating positions, and the cars were put to bed until the first test session the next day.

With all the anticipation and anxiousness leading up to the beginning of this season, it was slightly anticlimactic to arrive at the track Thursday morning to rain. The forecast said it would rain on and off throughout the whole weekend. Rain tires were mounted up and the crew and drivers dug right in and got to work.

Friday was sunny, clear, and dry and allowed the team to really start finding its groove with the new GT3 while Auberlen and Hull exchanged notes.

James Clay and Charlie Postins, drivers of the No. 36 OPTIMA Batteries / Lifeline USA M4 GT4, were busy getting comfortable with driver changes while James Walker, Jr. and Devin Jones, drivers of the No. 82 Red Line Oil / Veristor M4 GT4, poured over data to find a tenth here and there to make the most of Sonoma, which in the past has never been the best track for the BMW.

With rain sprinkling on and off throughout all qualifying sessions, the goal was equally about surviving as it was about finding speed. With the largest GT4 field on record at 41 cars, there wasn’t a lot of open track and plenty of close calls while everyone scrambled to put down their best lap.

The forecast was finally dry and sunny for both race days.  Auberlen and Hull had a solid Saturday running in the top-three the entire race and finishing on the podium in third. Sunday they had a tougher time getting to the front and finished seventh. In a car that was delivered only a handful of days prior, the team was very pleased with the results.

The pair of M4 GT4s took to the track, and the No. 36 of Clay and Postins started on the pole and took the win for Saturday by less than two tenths of a second! Sunday they managed to stay up front once again and grab another podium with a second-place finish. The No. 82 of Walker, Jr. and Jones was in the thick of battles every lap and managed to dodge many offs, crashes, contact, etc. to keep the car clean and intact. After the dust settled, they came home with a top-10 finish in the incredibly competitive field of over 20 Pro/Am entries in GT4 America SprintX both Saturday and Sunday.

Starting off with three podiums out of four races is an excellent kick off to the season, and we’ll be rolling this momentum right into the next race at Ozarks International Raceway on the weekend of May 20-22.

BimmerWorld Racing 2022 SRO Season Announcement

BimmerWorld Racing is proud to announce its return to the SRO Motorsports America series. The team will be bringing two new BMW M4 GT3s to compete in Fanatec GT World Challenge America powered by AWS and a BMW M4 GT4 to compete in Pirelli GT4 America for the 2022 season.

With the highly anticipated arrival of the BMW M4 GT3, team principal James Clay had his sights set on making the jump from the GT4 class to GT3 for 2022. In November of 2021 Clay was selected as one of five drivers to pilot the very first M4 GT3 on American soil which gave him a first look at the amazing machine that BMW Motorsport created and some very valuable seat time. “The M4 GT3 is a very well thought out and designed car,” Clay explained. “It was intuitive to drive and nicely composed. I can’t wait for our team to dig in and really start learning the new machine!”

Clay will be piloting the No. 36 OPTIMA Batteries BMW M4 GT3 alongside Ari Balogh, a familiar face to BimmerWorld Racing. Balogh previously raced with BimmerWorld in 2017 and is no stranger to sports car racing. “Ari was last with us in BimmerWorld-built ST cars, so the GT3 is obviously a different thing,” Clay continued. “Ari has been busy in GT4, GT3, LMP3, LMP2, and a range of other equipment and series, so I know he’s well-prepared for his first GT3 season, and I’m thrilled to have him back with us and as my co-driver for the first time.”

Bill Auberlen and Chandler Hull will be returning to SRO America with BimmerWorld Racing for their third and fourth seasons respectively in the No. 94 TACenergy / OZIUM BMW M4 GT3. “Bill obviously has a wealth of experience in BMW cars, including several previous GT3 generations, and was at the American rollout of the M4 last year, which will be super helpful as we develop the new car,” Clay added. “Chandler has also gained tremendous experience already this year in the M4 GT3 in the Creventic Dubai 24H and the four Asian LeMans series races, so I think everyone is really well-prepared to make this inaugural season a great one.” While Clay, Auberlen, and Hull finished off the 2021 season with a GT4 class win at the SRO Intercontinental GT Challenge Indianapolis 8-Hour Endurance Race for the second year in a row, this will be the first year that Auberlen and Hull share the same car throughout an entire season. 

Devin Jones and James Walker, Jr. will be behind the wheel of the No. 82 Red Line Oil / Veristor BMW M4 GT4 in GT4 America SprintX. The 2022 season will be Jones’ first in SRO but follows his long history with BimmerWorld Racing in IMSA including a ST class championship in 2018 and co-driving alongside Clay in the No. 82 M4 GT4 for two seasons with multiple wins and podiums.  This will be Walker, Jr.’s third season returning to the SRO GT4 America series where he has collected four wins with previous teammate Bill Auberlen. “I love both of these guys and am excited to have them together in a car for the season,” said Clay. “They have both been successful with BimmerWorld and the M4 GT4, and they are both important to the continuity and culture of our team.”
