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.

Custom New York Mets Jerseys . -- Cam Newton pranced into the end zone, placed his hands over his chest and did his familiar Superman pose. NEW YORK -- J.R. Smith left Anthony Bennett standing still and Tristan Thompson on his backside. The New York Knicks didnt just beat the Cleveland Cavaliers, they embarrassed them. Carmelo Anthony and rookie Tim Hardaway Jr. each scored 29 points, Smith had 19, and the Knicks won 117-86 Thursday night for their fourth straight victory. The Knicks wrapped up a 10-6 January after going just 9-21 through the end of December. They have rebounded from losing the first three games on their franchise record-tying, eight-game homestand and can finish it with a winning record if they beat Miami on Saturday night. "It is starting to feel a lot better here on our home court to win basketball games," Anthony said. "Were just trying to keep it going." Anthony scored 18 in the first quarter, only two off his total from his franchise-record, 62-point game Friday night. But he sat nearly half of the second quarter to fall well off the pace, as he had 37 points at halftime that night. He still scored enough to become the 50th player in NBA history to surpass 19,000 points. Hardaway had a career high in points and tied the Knicks rookie record with six 3-pointers. "I knew that if I could shoot the ball very, very well at the next level, then I should be able to help the team out," he said. But the dazzling plays were provided by Smith, who had to keep himself from laughing when he crossed over Thompson so bad that the forward fell down as Smith was making a jumper. Smith was starting for Iman Shumpert, who was out with a sprained right shoulder. The Knicks were also missing Andrea Bargnani (left elbow ligament), Kenyon Martin (sprained left ankle) and Amare Stoudemire (sprained left ankle), who are all starters or key reserves. Even without them, they cruised to their third easy victory during their winning streak. "These are the bright spots you want to have, especially playing at home," Smith said. "Youve got your teammates on the bench going crazy, guys on the court are excited and love to play the game and theres nothing better than that." Kyrie Irving scored 24 points for the Cavs on a day in which his long-term commitment to Cleveland was again questioneed.dddddddddddd "Theres just so much negative attention. I mean I know were struggling, but I mean its just not about me. Its about our team," Irving said. Bennett, the No. 1 overall pick, was coming off a season-best 15 points in his last outing. But this one was another of the forgettable performances that have made up his season: four points on 1-of-6 shooting. He came in a little more than 4 minutes into the game, and the Knicks immediately began attacking him. Smith had the ball in the corner and blew by him along the baseline before pulling the ball down while in the air and then pulling it back up before slamming it in. Anthony had the ball near the free throw line on the next possession, easily went by the rookie and laid it in to make it 26-9. The Knicks doubled the Cavs up at 58-29 when Anthony made two free throws with 4:23 remaining in the half, and New York led 60-36 at halftime. The Cavaliers have lost three straight and five of six. General manager Chris Grant said Wednesday that the Cavs "lack of effort is just not acceptable," but they were so bad so fast in this one that it was hard to tell if the effort was any better. But the bigger concern for Cavs fans may have come earlier in the day, when an ESPN.com writer wrote that Irving, the 2011 No. 1 pick, was already telling people privately that he wanted out of Cleveland. He said it was too early to say if he would sign an extension this summer, but said he enjoyed playing for the Cavaliers. "Im still in my rookie contract and Im happy to be here and Im pretty sure that Im going to be here for a long time," Irving said. "Im not saying anything to foretell the future, but Im pretty sure the relationship I have with (owner) Dan Gilbert and management extends off the court and I enjoy being here." Dion Waiters had 21 points for the Cavs, who played without Anderson Varejao (bruised left knee) and allowed the Knicks to shoot 57 per cent from the field. NOTES: The crowd included Denver Broncos defensive back Champ Bailey and NBA Commissioner David Stern, who is retiring Saturday. The Knicks honoured Stern with a video narrated by former Knicks star Bill Bradley, a member of both of New Yorks championship teams. ' ' '
