Microsoft to sponsor Kahne at Sonoma

This weekend at Sonoma Raceway, Kasey Kahne will pilot the #5 Windows 10 Chevrolet SS.

The northern California track marks the first time the major technology partner of Hendrick Motorsports has adorned the #5 Chevrolet SS.

In just his first seven starts at the wine country track, the Enumclaw, Washington, native earned two pole awards - 2008 and 2010 - and one win. Kahne won the 2009 race by leading 37 laps and taking the checkered flag with a 0.748-second margin of victory over Tony Stewart. Each of his last four starts at Sonoma have resulted in top-10 finishes, most recently a ninth-place result in last year's race at the 1.99-mile track. In total, Kahne has led 41 laps throughout two races in his NASCAR Cup Series career at the 10-turn road course, which ranks him ninth among current drivers.

According to NASCAR's loop data since 2005, Kahne ranks second in green-flag passes with 718 and quality passes with 311. Quality passes are the number of times a driver passes another car that is running in the top 15 while under green-flag conditions. He's fifth in laps in the top 15 with 786 and ranks sixth in the fastest laps run category with 45. He's 10th in driver rating with a high rating of 132.4. The driver rating is a formula that combines wins, top-15 finishes, average running position while on the lead lap, average speed under green, fastest lap, most laps led and lead-lap finishes.

Mechanic Charley McDonell, a longtime member of Kahne's team, is the only California native on the #5 Windows 10 team. He hails from Cottonwood, California, which is located approximately three hours north of Sonoma Raceway.
