Mercedes and Ferrari insist F1s engine manufacturers have gone out of their way to devise more cost-effective regulations - despite Christian Horner claiming the sport is nowhere on the matter. After a 2015 season in which engine politics dominated the off-track agenda as Red Bull threatened to quit F1, the FIA charged the sports four manufacturers - Mercedes, Ferrari, Renault and Honda - to come up with proposals to tackle four key areas of concern in time for 2018 at the latest.These were a reduction in the cost of customer supplies, a guarantee to supply all teams, performance convergence, and improving the noise of the engines. In January, in exchange for keeping the current hybrid technology in place until 2020, the manufacturers agreed to lower the price customer teams pay for their engine supplies to €12m. The FIA said significant further progress had been made and placed a deadline of April 30 for the plans to be formally agreed.However, less than a fortnight before the new rules are supposed to be signed off, Red Bull boss Christian Horner cast down on the chances of agreement being reached.As we sit here now, we are not anywhere near having met any of those criteria and I think unfortunately what will happen, as is often the case with these things, time will run out at the end of the month and nothing will be achieved and nothing will change, Horner said at the Chinese GP. There is one more attempt in the Strategy meeting and the Commission meeting at the end of the month to discuss and table the concerns and where were at, but failing that regulations will inevitably stay as they are.However, Mercedes and Ferrari - who between them supply more than half the grid with power units - have countered Horners claimsFerrari chairman Sergio Marchionne told Sky Sports F1: We have gone miles in terms of engine supply.We have found a way in which the four engine manufacturers can continue to supply the sport on a way that may not be the most economically advantageous, but it does provide continuity for the other teams and I think thats important. So hopefully that will get through. Mercedes chief Toto Wolff suggested Horners comments were a bit of a one dimension and insisted the German manufacturer had gone further than they would have ideally liked to on the issue of supply guarantees in particular.Weve offered much cheaper engines and actually met the targets we set ourselves, the Austrian told Sky F1. We have structured an obligation to supply - which we dont like particularly, but we have offered it to not run into a Red Bull situation again - and all that is on paper.But then it comes down to the detail of the contract and obviously not everybody is happy. He [Horner] isnt happy, but its about finding a compromise.In an attempt to push the manufacturers towards agreeing concessions, Bernie Ecclestone and FIA president Jean Todt controversially proposed the introduction of an independent budget engine for 2017, which would use simpler technology and be made available at a fraction of the cost of the current V6 turbo units.Marchionne says all the engine manufacturers are in agreement that the existing technology should remain the basis for future regulations. Ted Kravitz analyses the 2016 Formula 1 Chinese Grand Prix from Shanghai International Circuit On the larger issue of simplifying the powertrain, I think we need to be careful that we dont end up turning the sport into something that its not supposed to be, he said.This is supposed to be the leading edge of automotive experiences and so the powertrain needs to reflect the development of the industry itself.I am happy with the way in which the powertrain has developed today, it doesnt meet everyones objectives - Red Bull has got a different view - but we are of the view that we need to continue in this fashion and its a view thats shared by the other engine manufacturers.Meanwhile, on the issue of making the current engines louder, Wolff confirmed: We are working on various concepts and have made it one of the key points in order to find solutions.Dont miss the F1 Report on Wednesday at 8:30pm on Sky Sports F1 for full analysis of an action-packed Chinese Grand Prix at the Shanghai International Circuit.

PITTSBURGH -- His first real game in 11 months finally at hand, LeVeon Bell expected a few jitters. Or maybe a least a small sliver of rust.Nope. Maybe because the Pittsburgh Steelers running back was too busy providing a needed reminder of what he can do when hes healthy and -- perhaps just as importantly -- not in trouble with the commissioners office.His feet jitterbugging through the Kansas City Chiefs defense with alarming ease, Bell rolled up 178 yards of total offense in a 43-14 romp on Sunday night that showcased just how dangerous the Steelers can look when all of their remarkably talented parts are on the field at the same time.Its the `Juice, wide receiver Antonio Brown said. Anytime we have LeVeon out there on the field, we know the problems hes going to present to the defense.One the Chiefs (2-2) had no answer for, not after quarterback Ben Roethlisberger lit them up for four first-half touchdowns (five in all) and then let Bell get to work behind an offensive line that dominated the line of scrimmage.I was in the flow of the game, Bell said. I wasnt even thinking about (being rusty).Lining up all over the field in a variety of formations, Bell caught five passes for 34 yards and ran for 144 yards on 18 carries, including a 44-yard zig-zag in the fourth quarter that highlights Bells unique combination of patience and agility.We asked him to do a lot, Roethlisberger said. Not just be a running back and run the ball. But we put him in motion. We put him at wide receiver. We threw screens to him. We did a lot. And thats the confidence and faith we have in him and his ability.Considering he missed the second half of 2015 with a torn MCL in his right knee and the first three games of this season while serving a suspension for violating the leagues substance abuse policy, Bell wasnt exactly going to be picky about how he was used. Simply being out there and looking like the player who was an All-Pro in 2014 was enough.I just missed it, Bell said.And the Steelers missed him, recovering from a 31-point loss to Philadelphia the week before by handing Kansas City its worst setback in Andy Reids three-plus years on the job.Any time you get blown out, you want to respond, Brown said.STAR WATCH: Roethlisberger was held in check in a 34-3 meltdown at Philadeelphia.dddddddddddd A week later, he had as many touchdown passes as incompletions while going 22 of 27 for 300 yards and a quarterback rating of 152.5. Two of Roethlisbergers passes went to Brown while Markus Wheaton, Darrius Heyward-Bey and Jesse James caught one each.When you have a Hall of Fame quarterback, it looks good like that, center Maurkice Pouncey said.Brown boosted his career touchdown reception total to 42 and paid tribute to legendary golfer Arnold Palmer (a western Pennsylvania native) by wearing a pair of cleats that featured Palmers image.SLOPPY SLOPPY: A week after forcing the New York Jets into eight turnovers, the Chiefs got careless with the ball. The game turned in the first quarter when Spencer Ware fumbled in Kansas City territory to set up one touchdown and Smiths ill-advised screen pass was tipped and picked off to set up another.That game got out of hand early, Smith said.Kansas City will have plenty of time to figure out what went wrong. The Chiefs are off next week before traveling to Oakland on Oct. 16.Hats off to (the Steelers) for bouncing back after getting their tail whipped, Kansas City tight end Travis Kelce said. We have to do the same thing here over the bye. Tonight it was rough to go through this.GANG GREENE: Pittsburghs struggling defense received an impassioned pregame pep talk from Hall of Fame linebacker Kevin Greene, who was given the Ring of Excellence during a halftime ceremony. Whatever Greene said worked. The Steelers finished with four sacks -- three more than they had in their first three games combined -- and harassed Smith up and down Heinz Field.COSTLY WIN: While Kansas City escaped with just one players status uncertain after running back Knile Davis was evaluated for a concussion, the Steelers will prepare for a visit from the Jets with the status of several starters to be determined. Right tackle Marcus Gilbert (foot) and linebacker Jarvis Jones (ankle) left and did not return. Wide receiver Heyward-Bey is dealing with a shoulder problem and reserve linebacker Anthony Chickillo exited with a left knee injury.---AP NFL website: www.pro32.ap.org and http://twitter.com/AP-NFL ' ' '
