Formula one teams meet in Spain in the midst of the excitement that the combination of KERS, DRS and Pirelli will provide an unusual level of overcoming the Montmelo circuit, which in the past has generated discrete races with relatively little traffic.
McLaren team boss Martin Whitmarsh has only one who believes that competition is to strengthen the technical success of 2011 were no changes to the rules.
"I'm especially curious to see how they affect Sunday Grand Prix," said Whitmarsh. "We have seen how DRS and influenced the hybrid KERS race so far this season, so we'll see how things go in Barcelona as the Spanish Grand Prix has shown few overtaking opportunities."
McLaren will be one of the teams making several important updates for this race - Director of Engineering Tim Goss reveals that they are over 10 - you just miss the mark with them in time for Turkey. "As usual, the relentless pace of modernization continues," he said. "We have a set of improvements made in Spain. It is a package of about 10 to 12, some of which are recognizable from the outside and others not.
"Our goal is to win races and championships and we need to close the gap on Red Bull. We just keep eroding the problem. We had a package of Turkey that was there. We're trying to always get the speed upgrade as fast circuit possible. Just before that Turkey had a minor problem that meant he was not convinced that the update would be sustainable over a race distance. So we pulled out of this at the last minute. We will re-evaluate all of our questions here Friday. "
Ferrari will also be a major upgrade, and after his podium in Turkey, Fernando Alonso believes he can still fight for the championship this year.
"You know I like playing with numbers - and I went back and forth between home, Maranello and Turkey, I made a comparison between my first four races last year and this year's Grand Prize for," he said. " What came out of this game is that compared to 2010, I'm running eight points (49 against 41) but in the same four races this year, I put 13 more points at home compared to last year (41 vs. 28 .)
"It is true that my current gap at the top of the drivers' championship is much higher (52 points) compared with what was after Shanghai 2010 (11 points), but I remember very well that after Silverstone 47 points away and had eight races remaining.
"Today, we still have a 15 Grand Prix events. This shows that you can see the same thing in two different, even completely opposite ways. The most important thing is results and we started to make the podium, we need to make up regular basis and, if so, I think we have the opportunity to re-fight for the title. "
Mercedes will have a revised aero package that the team of Ross Brawn believes that Michael Schumacher can boost their fight-back here, and Sauber, Force India and Williams. Lotus and hormone replacement therapy also major changes.
The primary goal during a second per lap is the progress of dollars that could put them firmly in the midfield, the latter will be run for only the second time in the house. "The Spanish Grand Prix is the perfect setting for the team to show fans that we can and hopefully make the next leap ahead of home crowd," said Colin Kolles team boss HRT.
Virgin-third of new players believe they have learned a lot about the update, took in Turkey after the recent drive in a straight line tester Adrian Quaife-Hobbs is aquaplaning in Spain.
Meanwhile, in general, Red Bull are convinced to stay the pace in 2011 the composers for the fifth Grand Prix in succession.
The main feature of the 4655-mile Circuit de Catalunya is the long pit straight, which also provides drivers with the longest second from the network in the first round. A 830 heavy thinking DRS will provide area detection point, shortly before the final turn and the activation area began shortly after, that we attempt to move a lot of cornering.
However, the combination of different parts of Barcelona, which highlights all aspects of performance of a car and is very hard on tires. Pirelli tires will be difficult for his new "money" that is a bit more durable race distances, with their "yellow", created easy option as this weekend.
Catalonia is a popular place and test equipment have tried all Pirelli products here on previous occasions, once last winter and two in the official pre-season testing. With the ongoing campaign of Pirelli test last month, this means that everyone has much more information on tire performance they did in the first four races.
The time at Montmelo usually sunny with few clouds predicts a high temperature of 24 degrees Celsius on Thursday and Friday to 23 on Saturday. Is expected to increase again to 25 on Sunday.
The Spanish track is nearly identical to Red Bull's Mark Webber won the 2010 race, the only significant changes greater advantage in times seven and eight have been installed for winter testing.
