Mercedes drivers Lewis Hamilton and Nico Rosberg have been told that they risk being ordered how to drive by their teams if they collide again.Hamilton, the defending F1 champion, and Rosberg crashed on the final lap in a dramatic end to the Austrian Grand Prix last weekend.The incident happened when Hamilton was chasing race leader Rosberg and trying to find enough room to pass him.Rosberg refused to give any ground and the crash cost him valuable points, as Hamilton took his third win of the season and Rosberg finished fourth.It is the second time this season that they have crashed, following a similar incident on the first lap at the Spanish Grand Prix -- although both drivers went out so neither gained any points advantage.We have therefore strengthened our Rules of Engagement to include much greater deterrents to contact between our cars, Mercedes said Thursday in a statement following a team meeting. If the drivers do not honor the revised Rules of Engagement, we may impose team orders as a solution of last resort.Under team orders, team management can effectively order a driver by radio to drive a certain way by slowing down or not taking risks. A driver can also be told to allow his teammate to pass.Mercedes hopes the new rules will prevent further incidents between the pair, who grew up racing karts against each other and have a history of feuding at Mercedes.With these in place, we will trust our drivers to manage the situation between them on track. Their destiny is in their own hands, Mercedes said. The drivers were also reminded that we may issue instructions during the race to protect against a potential loss of constructors points.Rosberg, who has five wins so far this season, has seen his overall lead over Hamilton slashed to 11 points -- having won the first four races of the season. At one stage the German driver led Hamilton by 43.He blamed Hamilton for the crash in Austria, although replays appeared to show that Rosberg -- whose tires were almost worn out -- did not give Hamilton enough room. Hamilton was jeered on the podium by a section of the fans.Two seasons ago, it was Hamilton who was left fuming as Rosberg clipped his car and sent him crashing out of the Belgian GP, and earlier that season Rosberg crashed late in qualifying when under no pressure at all, bringing an end to the session with Hamilton poised to beat his leading time and get pole position.Hamilton and Rosberg also tangled on the first lap at the Canadian GP this season.In the past five races, there have been three incidents which have cost us over 50 points in the constructors championship, Mercedes said.Still, for now, Mercedes are not imposing team orders the way Red Bull did when Sebastian Vettel and Mark Webber were competing for the title. Webber and Vettel had a tense relationship and sometimes ignored their own team orders during a race.Hamilton and Rosberg will resume their title tussle at this weekends British GP at Silverstone.

The speculation went into meltdown mode, of the golden nugget variety. Orlando Cepeda Jersey . Vettel was 0.168 seconds faster than Red Bull teammate Mark Webber around the Suzuka circuit. Mercedes driver Nico Rosberg was two tenths of a second off Vettel. "The car balance is decent, but I think we can still improve," Vettel said. http://www.sfgiantsrookiestore.com/ . JOHNS, N.

CONCORD, N.C. -- Kyle Busch has shown repeatedly he can win at Charlotte Motor Speedway on the Nationwide and Truck series. The question remains whether he can capture that elusive first Sprint Cup victory. Busch dominated Saturday, racing to his sixth Nationwide Series victory of the season and record seventh career win at the 1.5-mile track. He also was Truck Series winner at the track last week, his fifth victory in that circuit at Charlotte. On Sunday, he looks to make it a clean sweep of all three series events with a win in the Coca-Cola 600. Busch has finished in the top eight in 10 of the last 11 Sprint Cup races at CMS but has never won -- a clear source of frustration. "Definitely" Busch said. "I have been close here so many years. Two years ago at the fall race I led a ton of laps and then Matt Kenseth passed me with like eight laps to go. Ive certainly had some devastating moments here at this race track." He thinks he has a "top five" car for Sunday. There was no doubt he had the top car Saturday. Ten years and a day after his Nationwide debut, Busch won for the record 57th time in the series. And he did it in dominating fashion. Busch started on the front row and led 186 of the 200 laps. Thats the most laps led at this race since Dale Earnhardt led 194 in 1986. Busch managed several late restarts to break a tie with Mark Martin for the most Nationwide victories at the track. "Mark is really, really good in the Nationwide series and theres a lot of things Im beating him at, which is cool," Busch said. "This is cool for us and great for thiss team.ddddddddddddIts fun to come to Charlotte. Its my favourite track." With 13 laps to go Busch beat Kasey Kahne off the restart and was never challenged the rest of the way with the clean air helping him cruise to the finish line. "I got to the outside and just didnt get the run," Kahne said of the final restart. "It was over at that point. Kyle Busch is tough to beat in this series." Busch actually stole a page from Kahnes book late in the race, noticing his primary competitor had found success -- and was gaining ground on him -- when he moved up to the top of the track. "I hadnt been up there all day, so it was a little scary," Busch said. Once Busch made the move his lead began to expand over Kahne. Four of the top five finishers were Sprint Cup drivers as Kahne was second, followed by Joey Logano, Kyle Larson and Kevin Harvick. "We have to find a way to beat that Kyle Busch guy, but hes pretty good," Logano said. Nationwide Series points leader Regan Smith was 10th. Former X Games star Travis Pastrana endured a scary moment late in the race when the back of his No. 60 Ford hit the outside and spun across the track and hit the infield wall head-on. But Pastrana was able to get out of his car and walk away. He said he felt fine, a testament to some of the safety measures NASCAR has installed over the years. "I was fighting for that lucky dog spot," Pastrana said. "But our car was free at the beginning of the run." Michael Annett, racing for the first time since his crash at Daytona in February, finished 17th. ' ' '
