  • XFINITY Qualifying procedure for 2015: In the NASCAR XFINITY Series, cars starting in positions 1-33 will be determined by their fastest single lap during qualifying in descending order with the fastest qualifier starting first. The next six positions will first be assigned to the highest ranking cars in owner points that have attempted all of the races, have not already earned a starting position through qualifying and have entered the event by the posted entry deadline. The final starting position will be awarded to the most recent eligible past champion driver. If there is no eligible past champion driver, then a seventh car will make the field based upon owner points.
    Prior to this enhancement, the top 30 cars in owner points were guaranteed a starting spot in each event. Now, a maximum of seven cars will be locked into a given NASCAR XFINITY Series race. If a qualifying session is cancelled because of inclement weather, the field will be set per the rule book with starting lineups determined by practice speeds.

  • Notes: Teams in both the NASCAR Sprint Cup and Xfinity Series will run the same tire set-up at Fontana this week . . . while this is the first time these teams have run this left-side tire code (D-4636), they have run this right-side code (D-4408) at this track since 2011 . . . compared to what was run at Fontana last year, this left-side tire features a slight construction change, and a compound change to enhance grip . . . Goodyear held a tire test at Fontana last October 28-29 . . . teams and drivers participating in that test were the No. 6 Roush Fenway Ford with Trevor Bayne, No. 42 Chip Ganassi Racing Chevrolet with Kyle Larson, No. 55 Michael Waltrip Racing Toyota with Brian Vickers and No. 78 Furniture Row Racing Chevrolet with Martin Truex Jr. . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Fontana . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.


    Kyle Larson Returns To Auto Club Speedway To Defend Win

    Last season, Kyle Larson put on a performance of mastery in the closing laps of the NASCAR XFINITY Series race at Auto Club Speedway. The young driver made daring passes in the final laps and fended off the pursuits of veterans Kevin Harvick and Kyle Busch to claim his first ever series victory and in turn thrust himself into the NASCAR limelight.  

    Now running full-time in the NASCAR Sprint Cup Series, Larson has been deemed by his fellow competitors as the ‘next big thing’ and his winning of the 2014 NSCS Sunoco Rookie of the Year honors confirms their assumptions.

    Despite his ever growing schedule Larson still makes time for Saturday races and this weekend he will strap into HScott Motorsports with Chip Ganassi’s No. 42 Chevrolet. Don’t be surprised if Larson contends for the win again this season, in two starts at Auto Club his average finish is 3.5. He also leads the series among active drivers in pre-race Driver Rating at ACS with a 113.7.

    Solid Start To Season Has Ty Dillon Opening Up Points Lead

    Following his fourth consecutive top-10 finish to open the season, Ty Dillon now commands a 14-point lead over second-place Chris Buescher, the biggest points margin following the first four races since 2013 when Sam Hornish Jr. led Justin Allgaier by 22 points.

    Dillon’s steady hand has him leading the pack and his Loop Data backs it up. In the first four races he has an Average Running Position of 7.608, has run 97.5% of his laps completed in the top 15 and 97.8% of his laps run on the lead lap - all three are best among series championship contenders. Dillon season-to-date Driver Rating is 102.9 - second only to his brother Austin Dillon (122.2).

    On the final leg of the West coast swing, Ty Dillon will lead the series to Auto Club Speedway for the 300 on Saturday, March 21 (FOX Sports 1). Dillon made his series debut at Auto Club last season where he started third and finished eighth. 

    2014 Series Champ Chase Elliott Continues To Climb The Standings

    After kicking the season off with a 28th-place finish at Daytona and burying himself in the points (20th), Chase Elliott has been on a mission climbing back up the standings. In the subsequent three races Elliott has jumped 16 spots to now fourth in the standings, 25 points back from Ty Dillon.

    Elliott turned red hot last season from the second to the eighth race on the schedule when he strung together seven consecutive top-10 finishes including his two wins at Texas and Darlington. This season he is looking to do the same and his last three consecutive top 10s have him on track to do just that.

    Expect Elliott’s consistency to continue this weekend at Auto Club Speedway; in his series debut at the 2-mile track he posted a solid sixth-place finish.

    Elliott’s season-to-date Loop Data supports his recent comeback. He leads the series championship contenders in Green Flag Speed, and has fourth-best Driver Rating (98.9) among championship contenders.

    Heavy Hitters Stack Auto Club Speedway Entry List

    The level of competition will be fierce this weekend at Auto Club Speedway especially with popular NASCAR Sprint Cup stars like Kevin Harvick, Brad Keselowski, Denny Hamlin, Austin Dillon, Kyle Larson and Sam Hornish Jr. touting the entry list. 

    When it comes to big names in NASCAR, nobody has flashed across headlines more this season than 2014 NASCAR Sprint Cup Series champion Kevin Harvick. Harvick will pilot the No. 88 JR Motorsports Chevrolet this weekend at Auto Club Speedway. Harvick has made 18 starts at ACS posting 15 top 10s and an average finish of 6.9. Harvick has yet to win at the 2-mile speedway.

    Team Penske has tapped Brad Keselowski to command the owner points leading No. 22 Ford this weekend. Keselowski’s teammate Joey Logano won last weekend at Phoenix catapulting car owner Roger Penske to the owner standings lead by six points over Richard Childress’ No. 33 team. Keselowski has made 12 starts at Auto Club Speedway posting four top fives and five top 10s.

    It will be Austin Dillon’s job to reclaim the owner points lead for his grandfather in the No. 33 RCR Chevrolet - which could be a possibility. Dillon has made two starts at Auto Club Speedway and both times he finished fifth. Dillon has been impressive in his stint in the No. 33 this season; he leads the series in season-to-date Driver Rating (122.2), Average Running Position (5.466) and Percentage of Laps Run on the Lead Lap (99.4%).

    Denny Hamlin will be substituting for the injured Kyle Busch in the No. 54 Joe Gibbs Racing Toyota. Joe Gibbs Racing has won nine of the last 10 races at ACS: Kyle Busch (six), Joey Logano (two) and Tony Stewart (one). 

    Sam Hornish Jr. will be in the No. 98 Biagi Bros. Ford for car owner Fred Biagi. This will be Hornish’s third series start at Auto Club Speedway where he has posted one top-five finish.

    I Wish They All Could Be California ... Drivers?

    California natives have been some of the most successful drivers in NASCAR national series history.

    You might recognize names like 6-time NASCAR Sprint Cup Series champ Jimmie Johnson (El Cajon) or 4-time NASCAR Sprint Cup Series champ Jeff Gordon (Vallejo) to name a couple. Since the NASCAR XFINITY Series inception in 1982, a total of 69 different drivers from the state of California have competed in at least one series event. This weekend, four drivers from California will compete in the NASCAR XFINITY Series race at Auto Club Speedway the 300: Kevin Harvick (Bakersfield), Kyle Larson (Elk Grove), Ryan Reed (Bakersfield) and Stanton Barrett (Bishop).

    Of the four entered Reed is the only driver that is running full-time for a NASCAR XFINITY Series title.

    “Being only a couple hours from where I grew up, Auto Club is a track I really want to do well at and I would love to get a win there,” said Ryan Reed. “I’m really excited to see all my friends and family this weekend and hope that we have a strong run in our Lilly Diabetes American Diabetes Association Ford Mustang.”

    Young Driver Brigade Continues to Impress

    For the fifth week in a row the NASCAR XFINITY Series points standings top five is dominated by drivers under the age of 24. The youthful group occupying the top five in points has an average age 21.2.

    The elder statesman of the youth contingent is points leader Ty Dillon who just turned 23 years old on Feb. 27th. The second and third positions in the standings belong to Roush Fenway Racing’s Chris Buescher (22 years old) and Ryan Reed (21 years old). The youngest of the group is fourth-place Chase Elliott at the age of 19. And last but not least, Sunoco Rookie of the Year candidate Darrell Wallace Jr. is at the ripe age of 21.   

    Sunoco Rookie Update: Wallace The Man To Catch

    Darrell Wallace Jr. continues to hold court in the Sunoco Rookie of the Year standings and this past week he extended his lead by seven points over second-place Daniel Suarez. Suarez moved ahead of Ross Chastain to the second spot in the rookie points following his career best series finish (11th) last weekend at Phoenix.

    This will be all three driver’s (Wallace, Suarez, Chastain) series track debut this weekend at Auto Club Speedway.
