Mercedes is looking to be the first team in recent times to maintain an advantage through a major rule change when Formula Ones aerodynamic regulations get overhauled this winter.The last two seismic changes to F1s technical regulations have put an end to periods of dominance for certain teams and brought about new eras of dominance in the sport. Big changes to the aerodynamic regulations in 2009 saw 2008s title protagonists Ferrari and McLaren flounder and Brawn GP emerge as champions with an innovative double diffuser concept. Once the double diffuser concept was copied by rivals and eventually banned, Red Bull emerged as F1s dominant force and win four consecutive titles until the last big regulation change in 2014. At that point Mercedes unlocked the most performance from the current V6 turbo engine regulations and has dominated F1 ever since.Rivals are hoping the 2017 rule changes -- which will see wider cars, wider tyres and revised aerodynamic regulations -- will finally crack Mercedes F1 hegemony, but the world champions engineering director Aldo Costa sees an opportunity to buck the F1 trend.Of course, as you said, the regulation change will be pretty vast, on a lot of car aspects, he said in Monza. We know we have in front of us this big, big challenge. We would love to be the team that is breaking exactly that rule -- that with the new rules there are new leaders. We would like really to break this rule, but it is tough.Although the chassis regulations are changing dramatically, the engine regulations remain unchanged, meaning Mercedes should retain its power unit advantage. At the Belgian Grand Prix Mercedes brought another upgrade to its already class-leading power unit and, although it still has the scope to bring further updates under F1s engine token system, Costa said its V6 turbo is already a good basis for further development next year.We are evaluating further development [this year]. We are not yet finally decided on what to do, but we are working hard to find new items to develop for this year, with an engine that is anyway a very good base for next years championship.

With the amount of money given to players by their clubs these days, it is a wonder that so many of those teams allow the sport to continue to take away many of their assets so they can play for a different team in the middle of their season.

PITTSBURGH -- Pittsburgh Steelers coach Mike Tomlin understands the negativity associated with a four-game slide and stressed his underachieving team would do its best to absorb it and move forward.Its a path theyll have to travel without Cam Heyward. The defensive end and co-captain is out for the rest of the season with an upper-body injury suffered in Sundays loss to Dallas.Heyward posted a message on Instagram on Tuesday afternoon indicating his 2016 season is over.My role will change as I can not play but it will not change the goals the team has set out, Heyward wrote .Maybe, but the loss of their most consistent defensive player will make achieving those goals far tougher.While Heyward didnt specify the exact nature of the injury, Tomlin described it as a pectoral or chest problem. Heyward was examined on Monday and received a second opinion on Tuesday before making the announcement.My patience will be tested, but I look forward to 2017, Heyward wrote. My hand will remain in the pile no matter what!The loss of Heyward deals Pittsburghs already struggling defense with another significant blow. He missed the first two games of his six-year career in October when he tweaked his left hamstring in a win over the New York Jets on Oct. 9.The Steelers run defense collapsed without Heyward, giving up 204 yards to Miamis Jay Ajayi and 127 to New Englands LeGarrette Blount , games that started a midseason swoon.Heyward returned against Baltimore on Nov. 6 and the defense seemed to make significant strides against the Ravens and held Dallas rookie Ezekiel Elliott largely in check last Sunday before giving up a pair of touchdown runs in the final two minutes of a 35-30 setback that left Heyward fuming and led quarterback Ben Roethlisberger to call out some of his teammates for a lack of discipline.Not exactly the kind of chatter the Steelers expected to be generating in mid-November.Tomlin understands the frustration of his players. At the same time, he believes emotions are not as important as results.Were not doing enough of the good things well enough to win on a consistent basis, Tomlin said. Weve got to change that. We still feel very comfortable that were capable of being a good football team. But those (hurt) feelings are lesss important .dddddddddddd.. than wins.A feeling the Steelers havent experienced in more than a month. While a potential reprieve awaits at winless Cleveland (0-10) on Sunday, the way Pittsburgh has played of late -- particularly on the road, where it is 1/3 -- doesnt exactly have Tomlin brimming with optimism.This is the third losing streak of at least four games during Tomlins tenure. The Steelers dropped five straight in 2009 and four straight in 2013. Both years Pittsburgh failed to make the playoffs.Missing out on the postseason seemed farfetched during a 4-1 start, but the Steelers have been so lifeless, careless or both recently that sitting at home in mid-January has become a very real possibility.The tape says there are not enough people doing the right things on a consistent basis, Tomlin said.A couple of his stars included. Though wide receiver Antonio Brown caught 14 passes for 154 yards and a touchdown against the Cowboys, he also was meekly pushed out of bounds at the Dallas 20 on the games final play rather than flipping the ball back into the field hoping for an unlikely score.Tomlin understands the odds of the ball somehow winding up in the end zone following a series of laterals are slim. Slim, though, is better than none.At the end of the game Id like to see us stay inbounds and see us fight and claw and scratch, Tomlin said.Something Pittsburgh will try to do without Heyward, who has embraced the role as the vocal leader of a defense in transition. Its telling both of Heywards effort and Pittsburghs issues getting to the quarterback that his 3.0 sacks lead the team even though he missed two full games and the part of another.My support for this team will only grow, Heyward wrote, and I look forward in watching this team grow and fight on.Game notes LB Steve Johnson (ankle) was placed on injured reserve. Pittsburgh added linebacker L.J. Fort to the 53-man roster. ... WR Darrius Heyward-Bey (foot) is out against the Browns. ...
