Kimi Raikkonen doesn't think the 2014 F1 cars will be particularly different to drive

Kimi Raikkonen: Back in red

This season sees a greater emphasis placed on engine power and fuel management with a switch to 1.6-litre turbocharged engines and some drivers have already expressed concerns at how easy it will be to spin the rear tyres with the amount of extra torque available.

However, having sampled Ferrari's new car on their simulator last week, Raikkonen thinks the situation may have been exaggerated.

"My feeling is that it's not going to be as different as people think, but I might be wrong," the Finn told Ferrari's official website.

"Hopefully we'll find out that it's pretty simple. For sure it is difficult for all the technical people to make a new engine, new gearbox, all this stuff, but as a driver it's not affecting the driving so much I don't think.

"We have new buttons and new things to follow, but let's wait and see. It'll be much easier to say after the first test."

Raikkonen delivered Ferrari's last world title during his previous stint with the team and he is targeting immediate success on his return.

"It's the only thing that you try to do - to win the championships," he added. "Hopefully as a team we can do that.

"It's going to be a long and difficult season, especially with the new rules. It's hard to say who is where and how it's going to be, but there are a lot of good people in the team, a lot of knowledge. We have to do the best (we can) and see where we end up. But there's every chance that we can do very well."
