Martin Brundle - The championship battle

After four seasons of Sebastian Vettel/Red Bull dominance, Martin Brundle says the reset in regulations certainly has the potential to shuffle the established order.

"If they hadn't of changed the cars you'd think that Red Bull had such a momentum going that it would be easy to say that Vettel would win yet again. But it is a massive change, so who knows? None of us know," the Sky F1 analyst said. "The teams are beginning to understand what they've got but they don't know how that compares with what the other teams have been achieving. So it's really unpredictable at the moment."

And does he therefore think Lewis Hamilton has a better chance of the title? "Yes I do. He went to Mercedes thinking about 2014 and beyond and had a much better 2013 than he expected. But the works teams, like Mercedes and Ferrari in particular, I think will have a big head start with these really complex new power packs...and of course that plays beautifully into Lewis's hands."

Ted Kravitz - The rules revolution

F1 undergoes a technical revolution in 2014 as in the biggest shake-up since the 1980s sees complex V6 turbo engines and enhanced, environmentally-friendly energy recovery systems introduced. Ted Kravitz explains the changes and the effect they are likely to have on the look, feel and sound of the sport in the video above.

"This is really the biggest change in Formula 1 regulations in living memory," Ted explained. "In such an era when we're all trying to buy more fuel-efficient cars and save fuel, it's time for Formula 1 to be part of the solution rather than part of the problem."

Johnny Herbert - The driver line-ups

With just two driver line-ups to date remaining unchanged for 2014, there are a number of mouthwatering new match-ups on the grid. Johnny Herbert runs the rule over the strengths - and potential challenges - posed by the pairings at Mercedes, Lotus, McLaren and Force India, although admits it is the Alonso/Raikkonen pairing at Ferrari that fascinates him most.

"Fernando's in his team and is expecting to be the man in the team so it's going to be about how that dynamic actually works - and that's going to be the interesting thing," Johnny said. "They're not going to be friends because they are going to want to beat the other. But I think Fernando has the inner strength to take it to Kimi.

"The conflict could become quite intolerable for the team and it's something they're going to have to manage very well. I think there is a chance of it imploding on itself, but if they do get a good car and the results start to come that will help that situation out."

Anthony Davidson - The young guns

Two exciting reigning champions from the junior ranks, Kevin Magnussen and Daniil Kvyat, make the steps up to F1 this year while 24-year-old Daniel Ricciardo takes on the challenge of being team-mate to Sebastian Vettel at Red Bull. Anthony Davidson thinks there are no question marks over either of Magnussen or Ricciardo's fundamental speed, but both have much to prove.

On McLaren rookie Magnussen: "I've raced with his dad, Jan, in sportscars and if he's anything as good as him we're going to be in for a great show. I think he's going to give Jenson Button in the sister car a good run for his money. You've always got to give a rookie half a season before you really start judging them, but I think come the end of the day he's going to be right up there speed-wise."

And as for Ricciardo: "He's going to be in one of the best cars out there but up against a very strong team-mate in the quadruple World Champion Sebastian Vettel. But it's a different scenario because he has the experience. He's proven his speed in qualifying already in Toro Rosso so I expect great things from him in speed alone. But how does he cope with the pressure of having that constant pounding from such a good team-mate?"
