Kimi Raikkonen has admitted that having a KERS system fitted to his Ferrari was no passport to success on the track at last weekend's Australian Grand Prix, but is hopeful that he can benefit more in Malaysia.

Those cars that ran the new technology in Melbourne - Ferrari, McLaren, Renault and Nick Heidfeld's BMW Sauber - struggled to make an impact on the race, as those teams that turned up with controversial diffuser designs dominated from the outset.

Even though he was subsequently in the hunt for a decent result before a mistake dropped him down the order in Melbourne, Raikkonen insisted that he had not gained that much from running KERS, which is supposed to provide a temporary power boost from energy scavenged under braking.

"It depends on many different things, it's not just that you get 80 horsepower and you are going to get around somebody or you can pass easily," he explained when asked why the KERS runners couldn't make up places on restarts.

"It's always [a case of] if your car is good or it's not good and if you get a good run on him, or he gets the jump on you at the restart. It's just not pretty straightforward thinking. At the start, it definitely helps but, at a restart, it's not so easy."

Former title rival Lewis Hamilton concurred, but offered one possible reason for the lack of effectiveness.

"The tyres are just the issue, I think," he revealed, "Getting heat back into the tyres is what stops everyone from overtaking.

"We used it every lap. It is the same for everyone else who has KERS - you use it as much as you can. There are some opportunities when you are behind sometimes to use it all in one lump, which does definitely give you a little bit extra end of straight speed to get a tow and have a better chance of overtaking, but it still ends up with you having to overtake at the end of the straight with a late manoeuvre. But who knows? Maybe here it will be even better with longer straights."

While Hamilton remained optimistic that he may have more to gain from KERS at Sepang, he was less positive about his chances of getting a good result to help begin the fightback after his post-Melbourne disqualfication.

"We are fortunate that it is reliable enough at the moment, but we definitely need to work harder to make it better," he confessed, "This weekend is going to be very tough again, and we don't have as quick a car as any of these guys, particularly here, but we are doing the best job we can with it."

Raikkonen, meanwhile, is more hopeful, knowing that he was to blame for the loss of points last weekend.

"The end result could have been pretty okay without my accident," he confessed, "Probably, the speed is not where we want to be right now, but this is a completely different place. It is more like a normal circuit compared to Australia, so we will see how we can do here. I still think that our car is not too bad, so we should be able to get good results once we get everything going well."
