As the gateway for the European leg of the season after the opening flyaway rounds, the Spanish GP typically sees more upgrades and car changes than any other event on the calendar. So heres what to look out for Barcelona this weekend… Having retained their F1 superiority at the start of this season, Mercedes unsurprisingly have not strayed from their tried-and-tested development policy. Its modest improvements, but thats always been Mercedes modus operandi, says Sky F1s Ted Kravitz. The most noticeable change on the W07 at Barcelona is a more pointy nose, while there are also tweaks to the cars engine cover, rear wing and mini monkey seat wing at the rear of the car. We have two new front wings and we tested them across the cars during P1, confirmed team technical chief Paddy Lowe.Meanwhile, Lewis Hamilton is running a new MGU-H unit in his Mercedes - his fourth such component of the season - after his breakdowns in China and Russia. This is an improved design following the failures experienced in China and Russia, the team stated. We have just one example available owing to the limited time since Russia ad it has been a superhuman effort to ready it. McLaren billed their upgrade for Barcelona as significant with a new aerodynamic configuration - including our second front wing iteration of the year - to be tested in practice on Friday.The wing arrived mid-way through practice and Ted Kravitz described the multi-element layout as the most intricate front wing Ive ever seen. It has grown an extra set of cascade wings, like an extra set of fingers sprouting out. It is brilliant, he said. The other new bits for McLaren are new brake ducts, a new floor, new diffuser and a new rear wing as well.Yet, despite its introduction and their double-points finish in Russia, the team have also cautioned against any expectation that the changes will dovetail with an equally-significant move up the field.The next race in Barcelona will be reasonably difficult for us, Jenson Button has warned. It certainly wont be easy. While well be evaluating upgrades to the car in Barcelona, so will many other teams, added team boss Eric Boullier. In their own words, Force India are looking for a luck upgrade as well as a car upgrade this weekend.A new front wing headlines the changes to the VJM09, which Ted Kravitz describes as more of a cutting edge design now, absolutely 2016 standard. There are also changes to the diffuser and rear wing too.Sergio Perez said that the front, rear, and floor of the car have been changed, as well as everything to improve flow quality. He added that rather than lap times, the team were looking for more drive-ability in the VJM09. Renault will be working overtime to right the wrongs of their dismal start to 2016. For the race weekend, their new car will be fitted with new front and rear wings while Jolyon Palmer will drive the new chassis, which debuted at last weeks filming day at Silverstone.But its their work at next weeks test which is likely to prove even more significant given it will impact both the works outfit and Renaults sole existing customer, Red Bull.Having spent only one development token so far this season, Renault will use the two-day meet to test out a new B-spec engine, which is forecast to reap a 30bhp improvement. Three points finishes from their opening four races have given Haas an unexpectedly strong basis from which to bolt developments on to the VF16.After racing their new front wing for the first time in Russia, the American team are adding a new-look rear wing for their package in Spain. Like fellow premium Ferrari engine customers Sauber, Haas will also use the Scuderias updated engine for the first time. However, team boss Guenther Steiner has stressed the team are adopting a piecemeal approach to 2016 development:We wont have big changes on a set schedule, Steiner said. Well introduce new parts when we feel weve made enough gains. New parts from our development will trickle in every few races, just like every other team does. A new car, let alone upgrades of significant note, were unattainable for Manor in 2015, but the situation is rather different this year and the MRT05 will feature a number of revisions for Barcelona.The package is extensive and includes new bodywork, floor and front and rear wings, in addition to other tweaks here and there as they aim to join the back of the midfield. Harshly illustrating the depths of the teams current struggles on and off the track, Sauber will not be introducing any new car upgrades this weekend - and with none in the pipeline either, the team will also sit out next weeks test.The only change for the C35 will be to the engine with suppliers Ferrari providing a power unit upgrade.

Oscar Klefbom also scored for the Oilers (13-27-9), who have won three of their last four and now sit four points ahead of last-place Buffalo. The Oilers are now 6-5-2 since interim head coach Todd Nelson took over as full-time head coach.Nelson, who has spent plenty of time watching Landers progress in the American Hockey League, is thrilled to see him start to shine at the NHL level.Thank goodness Anton Lander had the game that he did tonight. He was exceptional, by far the best player on the ice, Nelson said. I think he feels really comfortable and more confident when he looks behind and sees me. Ive been working with him every year since he came over from Europe, so I think that helps. Hes really improved his game. He has earned the opportunity. I thought he was outstanding tonight.Lander shrugged off his personal best three-point performance.I think we played all right, we can still get better, he said. You dont have to play great all the time, but if you get a win thats the most important thing. Its nice to get wins here the last couple of games. Its a good thing we have going on now, we have to keep it going.Tyler Myers and Rasmus Ristolainen replied for the Sabres (14-31-3), who have lost a franchise-worst 13 games in a row and only have one win in their last 18.The defence were involved, but it wasnt a 60-minute effort for all of us, said Sabres centre Torrey Mitchell. We play the first two periods well or we score the first goal, and get off to good starts and we just cant build on it right now.It is clear the frustration level is running very high for the Sabres at the moment.We had our chances, said Buffalo head coach Ted Nolan. With this team we need everyone, we cant afford two or three guys not playing well or not giving what they have to give. It seems like the same ones over and over again, but we only have 20 players, who else are you going to put in?I think we need to stay positive and just keep approaching every game like were going to win the game, added goalie Jhonas Enroth.dddddddddddd We cant go into every game thinking were going to lose the game. We have to stay positive and still believe that we can win games.The Sabres started the scoring just 2:22 into the first period as Mitchell won a battle behind the net and dished the puck out in front to Myers, who slipped a shot under the arm of Ben Scrivens— on a play the Oilers goalie would likely want to have a second chance at. It was Myers second goal of the season.Edmonton tied the game 1-1 with seven-and-a-half minutes left in the opening frame when Lander fed a puck from behind the goal line to Fraser, who beat Sabres starter Enroth with a slap shot for his sixth of the year.The Oilers surged ahead with five minutes to play in the first as Lander sent a backhand pass to Klefbom at the top of the circle and the young defenceman blasted his first goal of the season into the Sabres net.Scrivens was forced to make a couple timely kick saves in an otherwise uneventful and scoreless second period.Edmonton outshot Buffalo 24-16 through 40 minutes.The Oilers were down a defenceman six minutes into the third period as Buffalos Zemgus Girgensons directed Nikita Nikitin into the boards and the Edmonton blue-liner left the game clutching his shoulder.Edmonton took a 3-1 lead eight minutes into the third as a turnover allowed a two-man breakaway with Teddy Purcell feeding Lander for his first goal in 65 games- also giving him his first three-point game of his career. Fraser picked up an assist on the play, also giving him three points in the game.Buffalo closed to within a goal with 2:02 remaining as Ristolainen followed up on the play to bang home a rebound through Scrivens legs.However, the Sabres took a late penalty and couldnt complete the comeback, allowing the Oilers to run out the clock.
