NASCAR Sprint Cup Series
 
        === Multi-car wreck interrupts day two of testing at Daytona ===
 
 Daytona Beach, FL (Sports Network) - Several Sprint Cup Series teams had their
 pre-season testing at Daytona International Speedway cut short on Friday due
 to a multi-car wreck during the afternoon session.
 
 The accident occurred when Marcos Ambrose spun around in a pack of 18 cars
 after Dale Earnhardt Jr. was attempting to bump draft Ambrose on the
 backstretch at this 2.5-mile superspeedway. Twelve of the 18 cars riding in a
 pack were involved in the accident.
 
 The other drivers in the incident included: Jeff Gordon, Kasey Kahne, Jamie
 McMurray, Joey Logano, Kyle Busch Greg Biffle, Carl Edwards, Regan Smith, Aric
 Almirola, who is Ambrose's teammate, and reigning Sprint Cup champion Brad
 Keselowski.
 
 "I guess I just got caught on the edge of the bumper there, and with the
 shaped noses and the tires, just spun me out," Ambrose said. "It was hardly
 even a bump. It was just enough at the wrong angle, wrong time and just went
 for a spin. I feel bad for everybody because quite a few cars were torn up
 there."
 
 Earnhardt Jr. did not suffer any significant damage to his No. 88 Hendrick
 Motorsports Chevrolet and will continue with his test session, which concludes
 on Saturday.
 
 "We were just out there running around, and I felt like Marcos was backing up
 to me in (turns) one and two to get a run down the back," Earnhardt Jr. said.
 "I was just going to give him a push down the back straightaway and see if he
 could get the lead. I was trying to eventually get the lead myself. We got off
 the back straightaway and were just kind of pushing him along there and our
 cars sort of just didn't match up very well. I got him hooked into the fence."
 
 Teams are at Daytona this week to familiarize themselves with NASCAR's new
 sixth generation or "Gen 6" race cars for the 2013 season and prepare for the
 Feb. 24 Daytona 500. Most of the teams involved in the wreck did not have
 backup cars since the redesigned vehicle is currently in short supply.
 Keselowski was one of those drivers who was forced to head home earlier than
 expected.
 
 "I saw cars smoking and wrecking in front of me," Keselowski said. "I think I
 ran into the back of the 43 (Almirola) and someone ran into me. That is just
 the way this deal is. It is unfortunate but sometimes you have to wreck them
 to learn."
 
 Each of the three auto manufacturers in NASCAR's top series -- Chevrolet, Ford
 and Toyota -- have designs on the new cars that are different from the most
 recent ones used in the sport from 2007-12. Drivers have noticed a significant
 difference in the designs while bump drafting.
 
 "Definitely the drafting is not like it used to be," Earnhardt Jr. said. "You
 can't really tandem certain cars. Certain cars don't match up well. Our
 bumpers on the Chevy have a little bit of a point. It makes it a little bit of
 a challenge to get into guys and kind of help them. We definitely weren't
 doing that in the corner at all, because it was pretty hairy trying to do it
 on the straightaways."
 
 During the first day of testing on Thursday, most drivers did single-car runs
 while some did up drafts of up to four cars. There were no incidents during
 the morning or afternoon sessions.
