Red Bull boss Christian Horner has conceded his team may have to endure a slow start to the new F1 season. The former world champions unveiled a revised car livery for the new season at a launch event in Londons Brick Lane on Wednesday, although their new RB12 car is being kept under wraps until the opening day of testing on Monday.Red Bull, after months of uncertainty and political wrangling, have ended up continuing with Renault engines for 2016, but Horner has previously warned they face a transitional season while the French manufacturers work on finding a breakthrough for their struggles. And asked at the launch if he still expected a transitional year, Horner replied: I believe it will be. We are going to start the year hopefully with some progress from the end of last year, but with our engine partners commitment to buying a team now, were hoping to see staged progress during the course of the year.We are hopefully going to see a steady rate of improvement, so probably the second half of the year is going to be more competitive than the first half. Red Bull have gone for a matt finish on their 2016 livery After salvaging second place to Mercedes in the Constructors Championship in the first year of F1s turbo regulations in 2014, Red Bull were also overhauled by Ferrari and Williams last year and Horner is again expecting 2015s leading teams to be strong.However, echoing Red Bull technical chief Adrian Newey, Horner also hinted that sister team Toro Rosso could pose an early threat too following their switch to Ferrari power.We know that Mercedes and Ferrari are going to be strong because even if they did nothing, theyre still going to be in good shape, Horner said. Red Bulls new 2016 look F1s former champions go aggressive in design of new livery Its difficult to know. How much have Williams found? What have Force India done? Weve just got to focus on ourselves.We know Toro Rosso, for example, will make a big step. Weve just got to focus on ourselves and do the best job we can.Despite the Red Bull-Renault relationship lurching to the brink of divorce in 2015, its continuation on revised terms for at least one more season means the short-term success of the Milton Keynes team is still largely wedded to the competitiveness of the French carmakers engine.But despite Renaults winter takeover of Lotus re-establishing themselves as an F1 constructor, Horner insists he is not worried his team will now receive inferior treatment. Red Bull have unveiled their new car for the 2016 season We know well get the same product from Renault that the works team will get, he said.Lets not forget, we won a World Championship when they had a works team in 2010 so Im not worried about there being a differentiation in treatment. The most critical thing is that theyve made progress with performance and that hopefully will happen throughout the year.With Renault having played down their own chances in 2016, Red Bulls aerodynamic package will again prove particularly key in their attempts to mix it at the front of the grid.Horner revealed the team had pushed the mandatory crash testing for the RB12 right up to the limit ahead of next weeks opening test.Were probably the latest team to do any of the crash tests, which have all been done this week, he said. They started on Monday and finished about an hour ago and were ready to go testing in Barcelona. Hats off to everybody in the team for having done a fantastic job.The first Barcelona test starts on Monday February 22 and the Sky Sports F1 Digital team will be providing live commentary from dawn until dusk on all four days of both Barcelona tests while Sky Sports News HQ will also deliver live updates from trackside.

LOUIS -- Heading into the final stretch of the season, the issues for the Chicago Bears banged-up defence only seem to be getting worse. FAYETTEVILLE, Ark. -- Dusty Hannahs hasnt experienced all that many shooting slumps in his life, but the Arkansas guard might just have found the answer to his early season shooting struggles by not starting.For a second straight game, the Razorbacks sharp-shooter came off the bench on Tuesday night -- scoring 17 points in 17 minutes as Arkansas (7-1) rallied from a halftime deficit for an 84-72 win over Houston.Hannahs was 6 of 11 from the field and has now hit 5 of 10 3-pointers in his last two games, coming after he was held without a 3-pointer in the two games before that. After leading Arkansas in scoring last season, the senior is now embracing whatever role Razorbacks coach Mike Anderson gives him.I just tried to stop thinking about (missing shots), even though it was impossible to stop thinking about it because I was just watching so many misses happen, Hannahs said. ... I was relaxed the last game and relaxed this game, and I think its smooth sailing from here on, hopefully.Hannahs had plenty of help as Arkansas won its fourth straight game, with first-year junior Daryl Macon adding 17 points on 5-of-9 shooting. Moses Kingsley added 14 points and eight rebounds, while Dustin Thomas finished with 11 points as the Razorbacks shot 59.3 percent (16 of 27) in the second half after trailing 35-34 at halftime.But it was Hannahs who provided the biggest spark, particularly in the first half when he scored 10 points in nine minutes.Look how efficient he is, Anderson said. ... I think the key is getting playing time. Like I said, hes still a starter in my mind.Rob Gray scored 22 points to lead the Cougars (6-2), whose two losses this season have both come on the road against Southeastern Conference opponents. Damyean Dotson had 15 points and 10 rebounds, while Galen Robinson had 14 points and Wes Vanbeck scored 10.Arkansas entered having won seven of its last eight games against its former Southwest Conference rival Cougars, who were making their first visit to Fayetteville since 1991.The two teeams also came in averaging more than 84 points per game, though Houston struggled early while falling behind by as many as 14 points in the first half.dddddddddddd The Cougars rallied, however, to take a 35-34 halftime lead -- with 32 of those points coming from the backcourt quartet of Dotson, Robinson, Gray and Vanbeck.The four finished with a combined 61 points, but it wasnt enough to overcome Arkansas hot second-half shooting.We still had a lead in the second half, Houston coach Kelvin Sampson said. ... This is a game we could have won, but youve got to play a little bit better defense and get a little more production out of our bigs in a game like this.BIG PICTUREHouston: The Cougars had the guards to run with the Razorbacks, but they had no answers off their bench -- which was outscored 34-14. Houston entered averaging 85.1 points, but it shot only 40 percent (14 of 35) in the second half.Arkansas: The Razorbacks failed in their first true test of the season, falling 87-71 at Minnesota on Nov. 22. On Tuesday, they played like the team coach Mike Anderson had in mind when he signed guards Macon and Jaylen Barford from junior college -- with an eye on immediately turning around following a 16-16 season. While Barford struggled with only two points, Macon was in control throughout, a positive sign for a team intent on returning to the NCAA Tournament after missing it last season.MISSING DAVISDevin Davis, averaging 12.7 points and 7.4 rebounds per game, played only three minutes for Houston and was scoreless after cutting two fingers on his right hand early in the game. The 6-foot-7 junior needed six stitches to stop the bleeding, and Sampson was forced to play a smaller lineup without him.UP NEXTHouston begins a four-game stretch at home by hosting Rhode Island on Saturday.The Razorbacks wrap up five straight games at home when they host North Florida on Saturday.
