Not all teams announce their weekly race chassis'. Here is a list of those teams that do reveal the chassis in the teams race preview:
#1- Jamie McMurray - Manion and the No. 1 McDonald’s team will bring Chassis #1208 to Kentucky this weekend. This chassis has raced this season at Las Vegas, Kansas and Charlotte finishing eighth, 14th and 21st respectively. Most recently, this chassis raced at Michigan International Speedway, finishing 14th.
#2- Brad Keselowski - The No. 2 Miller Lite Dodge Charger team will race chassis PRS-822 during Saturday’s Quaker State 400 at Kentucky Speedway. Keselowski last drove this chassis to an 11th-place finish at Kansas Speedway in April.
#5- Kasey Kahne - Crew chief Kenny Francis has selected Hendrick Motorsports Chassis No. 5-717 for Saturday’s race at Kentucky. Kahne has recorded a pair of top-10 finishes in this car, crossing the line eighth at Kansas Speedway in April and ninth at Dover (Del.) International Speedway in June.
#9- Marcos Ambrose - The No. 9 RPM team has prepared chassis No. 693 for this weekend's NASCAR Sprint Cup Series Race at Kentucky Speedway. This Mac Tools Ford was run previously this season in the All-Star Race at Charlotte Motor Speedway.
#10- David Reutimann - Reutimann will pilot chassis No. 356, purchased from Richard Childress Racing in the off-season. Teammate Blaney drove the chassis last at Pocono Raceway. Reutimann drove the chassis at Las Vegas Motor Speedway, Auto Club Speedway, Texas Motor Speedway, Kansas Speedway and Dover International Speedway this season. He had his best showing in the chassis at Texas Motor Speedway when he drove from the 31st starting spot to finish in 26th place. His best qualifying effort was at Kansas Speedway where he qualified in the 16th spot.
#14-Tony Stewart - Chassis 14-640. This car debuted in May 2011 at Darlington Raceway where it enjoyed a solid outing, qualifying ninth and leading six laps before finishing seventh. It spent time in the wind tunnel afterward and made its second career start at Pocono Raceway in June. There, it qualified 15th and moved its way into the top-five by lap 124, only to be felled two laps later when Stewart reported that he had lost third gear. The balky transmission prevented Stewart from getting up to speed quickly on restarts, which conspired to leave Chassis No. 14-640 in 21st place when the checkered flag dropped. The car returned to Pocono in August where it rallied from its 28th-place starting spot and a flat left-front tire on lap 92 that at one point had Stewart a lap down to finish on the lead lap in 11th. Chassis No. 14-640 broke through in the first race of the 2011 Chase for the Sprint Cup at Chicagoland Speedway in Joliet, Ill., when it started 26th and led four times for 35 laps en route to the win. The car received a new body during the offseason and participated in a Goodyear Tire Test Feb. 7-8 at Texas Motor Speedway in Fort Worth. Its first race of 2012 and fifth overall came at Las Vegas Motor Speedway in March, where Stewart drove from seventh to lead three times for a race-high 127 laps to score his first Sprint Cup win at Las Vegas. Chassis No. 14-640 raced at Texas in April, but unlike its past performances at intermediate tracks, the car struggled, qualifying 29th and finishing two laps down in 24th. Numerous trips to the wind tunnel, along with a single-day test June 14 at Michigan International Speedway in Brooklyn, have the car better prepared for its seventh career start Saturday night at Kentucky.
#16- Greg Biffle - Primary Chassis: RK-803 Last ran All-Star – finished 22nd; Backup Chassis: RK-786 Last ran Homestead – finished 35th
#17- Matt Kenseth - This weekend at Kentucky, Kenseth will pilot the No. 17 Fifth Third Bank Ford Fusion. The primary chassis is RK-741. Last ran at Charlotte.
#22- A J Allmendinger - Allmendinger and crew will be racing their "PRS-823" Shell-Pennzoil Dodge Charger this weekend at Kentucky. This car made its debut for the team in Kansas back in April. Dinger won the Coors Light Pole Award and led 44 laps before secondary linkage woes put him 10 laps down and relegated him to a 32nd-place finish. The "PRS-819" chassis will serve as the backup Shell-Pennzoil Dodge for this weekend. This was the car Dinger drove to a second-place finish in the April Martinsville race.
#24- Jeff Gordon - Gordon and the #24 team will race HMS chassis 24-712 at Kentucky. The car finished 26th at California, fourth at Texas, 35th at Darlington and 13th at Dover in 2012.
#27- Paul Menard - Paul Menard will pilot Chassis No. 328 from the Richard Childress Racing NASCAR Sprint Cup Series stable. This No. 27 Chevrolet was last utilized in competition at Charlotte Motor Speedway in May where Menard started ninth and finished 15th. This chassis was also used at Phoenix International Raceway in March.
#29- Kevin Harvick - Kevin Harvick will pilot Chassis No. 381 from the Richard Childress Racing NASCAR Sprint Cup Series stable in this weekend's Quaker State 400. Harvick drove this Chevrolet to a 13th-place finish at Texas Motor Speedway in June of 2011. It was also driven earlier this season by Brendan Gaughan at Las Vegas Motor Speedway as a No. 33 RCR Sprint Cup Series entry.
#31- Jeff Burton - Jeff Burton will race chassis No. 367 from the Richard Childress Racing NASCAR Sprint Cup Series stable. This No. 31 Chevrolet, originally built in 2011, has been utilized twice during the 2012 Sprint Cup Series season at Kansas Speedway in April (started-12th, finished-22nd) and in the Coca-Cola 600 at Charlotte Motor Speedway in May (started-22nd, finished-19th). This chassis has seen significant track time in 2011 including visits to Indianapolis Motor Speedway (started-13th, finished-35th), Atlanta Motor Speedway (started-27th, finished-13th) and Kansas (started-31st, finished-21st). Burton also tallied a top-10 finish at Homestead-Miami Speedway, finishing 10th after starting 31st with this Chevrolet.
#36- Dave Blaney - Blaney will drive the No. 293 chassis, which he drove four times this season and five times during the 2011 season. The Harford, Ohio native’s best start with the No. 293 chassis was 17th at Richmond and best finish was 23rd at Phoenix this season. TBR purchased the chassis from Richard Childress Racing, where Jeff Burton drove the chassis prior to its debut with TBR.
#39- Ryan Newman - In six previous starts, Chassis No. 39-686 has one-top five and three top-10 finishes. The chassis already has five starts this season, including most recently in the Pocono 400 at Pocono (Pa.) Raceway. At Pocono, Newman had a strong car and looked to be a lock for at least the top-10. But a wild restart just 30 laps from the end of the race saw Newman drop from sixth to 11th place, which hampered his efforts in the closing laps. He finished 12th. In the non-points-paying All-Star Race at Charlotte (N.C.) Motor Speedway, Newman finished 10th after battling with a loose-handling car throughout the 90-lap event. Prior to the non-points race, Newman used Chassis No. 39-686 at Kansas
Speedway in Kansas City and at Las Vegas Motor Speedway. At Kansas, Newman ran in the top-15 for most of the race but, with less than 70 laps to go, he was forced to the pits for an unscheduled stop with what he thought was a deflating tire. He exited the pits one lap down to the leaders, ending his shot at a top-10 finish and relegating him to 20th place. At Las Vegas, Newman qualified a disappointing 18th but made a strong drive into the top-10, where he ran for most of the race. He drove from eighth to a solid fourth-place finish in the final four laps at the 1.5-mile oval. Last season, chassis 39-686 made two starts at intermediate racetracks during the 2011 Chase for the Sprint Cup Championship, which resulted in one top-10 finish. The chassis made its debut in the Bank of America 500 at Charlotte in October, where Newman started sixth, led six laps and finished a solid 10th. In the second start for the chassis, at the AAA Texas 500 at Texas Motor Speedway in Fort Worth, Newman recovered from a loose wheel and came back from two laps down to finish a respectable 16th.
#42- Juan Pablo Montoya - Crew Chief Chris “Shine” Heroy and the No. 42 Target team will bring Chassis #1205 to Kentucky this weekend. This chassis raced to a 12th-place finish at Kansas this season and a 20th-place finish in the Coca-Cola 600 at Charlotte Motor Speedway
#43- Aric Almirola - The team has prepared chassis No. 783 for the Kentucky race. Almirola earned the pole position in this car at Charlotte in May, and also ran the chassis at Texas and Las Vegas earlier this season.
#48- Jimmie Johnson - Chassis No. 714 serves as the primary for Johnson at Kentucky. Chassis No. 669 serves as the backup. #714 last ran at Charlotte finished 11th. It also ran at texas, finished 2nd.
#51- Kurt Busch - Chassis No. 557: Saturday night’s Quaker State 400 will be the second race of the 2012 season for Chassis No. 557. The team last used this chassis in May at Darlington (S.C.) Raceway, where it competed in the top-10 for the majority of the event before a late-race issue relegated it to a 21st-place finish. The team also used this chassis during the mid-April tire test at Dover (Del.) International Speedway. Prior to the 2012 season, the car was used as a road-course car. Hendrick Motorsports built this chassis with a universal clip, which allows for greater adjustments with the geometric points on the chassis. As such, the team converted the car from a road-course car to an intermediate track car for this season.
#55- Michael Waltrip - CHASSIS: 722 - Brian Vickers finished fifth at Bristol in this chassis while Mark Martin finished 21st in the All-Star race in Charlotte. Backup - 708 - has not raced in 2012.
