Each week during the season, About.com NASCAR Expert Matt Weaver will provide a power rankings list for the top-15 drivers in NASCAR.
The Fast 15 is a list of intangible qualities, based on momentum, attention and overall success in NASCAR over the past several weeks. That means it's entirely possible that a driver from the Camping World Trucks and Xfinity Series could appear alongside one of their Sprint Cup Series counterparts.
Don’t agree with the list? That’s okay! Just let Weaver know on Twitter at @MattWeaverSBN.
Kyle Busch
The defending Sprint Cup Series champion is at the top of his game right now. Busch led 352 of 500 laps on Sunday at Martinsville and completed the first-ever weekend sweep of the Truck and Sprint Cup Series at NASCAR's oldest track. These victories were also his first at the paperclip.
Jimmie Johnso
Even though he's still viewed as one of the Big Three at Martinsville, he just hasn't been a major player over the past couple of races in Virginia.

10 Best Teams in the History of Baseball
He was consistent on Sunday but still only finished ninth. On the positive side, this was his fourth top-10 of the season and he's second in the standings with a league leading two victories. They're likely the favorites this weekend at Texas.
Kevin Harvick
Martinsville was the first mulligan of the year for the 2014 champions and the first race they did not post a top-10 finish. They kind of hovered near the top-10 but just didn't catch the right breaks. They should be contenders at Texas this weekend.
Carl Edwards
Edwards has always struggled at Martinsville so credit has to be given to the No. 19 team for getting him a sixth place finish.
Joey Logano
At this point, Logano has to feel as though Martinsville is finding creative new ways to bite him. The Team Penske youngster won his third straight pole at the short track but is still looking for his first win. They just missed the set-up and spent the afternoon chasing both the car and the field.
Brad Keselowski
The 2012 Sprint Cup champion finished fifth but did it on the merit of his team's decision to pit for tires with 12 laps to go. His battered car looked closer to a demolition derby winner than one deserving of a Sprint Cup winner's sticker.
Denny Hamlin
On Friday, the five-time Martinsville winner declared himself the man to beat as long as he didn't beat himself on Sunday. He then proceeded to beat himself with a pit road penalty and then making a mistake under braking that sent him hard into the Turn 1 and 2 wall.
Dale Earnhardt Jr.
NASCAR's most popular driver was spun early after David Ragan hopped the curbing into his No. 88 but eventually rallied into the top-5. In the madness of the final restart, he was shuffled to 14th but said he had fun and that's all that mattered.
Austin Dillon
The No. 3 is supposed to run well on short tracks and that's what happened as Austin Dillon piloted his Richard Childress Racing entry to fourth on Sunday at Martinsville. Dillon and Slugger
Kurt Busch
Like many of the usual contenders, Busch's 13th is more indicative of the nuances of short track racing than what to expect for the rest of the season. That first win is right round the corner, perhaps as soon as Texas.
Martin Truex
Furniture Row gets a pass for finishing 18th at Martinsville but this is a team that really needs to get back on track at Texas, given some lackluster performances in recent weeks.
Chase Elliott
While it wasn't as bad as his Sprint Cup debut at the track last spring, Elliott spent much of Sunday off the lead lap and didn't immediately inherit the No. 24's ability to automatically contend every time it rolls into South Virginia.
Matt Kenseth
The nightmarish start to the 2016 season continued for Kenseth whom spent the majority of the day in the top-5 but sunk to 15th by the finish when he restarted from second and on the outside line.
Ryan Blaney
Not even a 19th place finish could dampen the coolness of seeing the No. 21 Wood Brothers team back at their home track.
AJ Allmendinger
While a second place at Martinsville can be easily dismissed as a short track fluke, the entirety of his season thus far can not. Through six races, Allmendinger and JTG-Daugherty are 12th in the standings with a average finish of 14.8. This team is legitimate.
