The pre-season winter testing is over, with the focus now firmly set on the opening Grand Prix weekend of the 2015 Formula One World Championship season.

Thousands of miles completed around the tracks of Jerez and Barcelona have put the majority of teams in good stead for Australia.

Mercedes look like they have maintained their competitive advantage from last seasons dominating 2014 machine. Ominously for the rest however they also appear to have improved upon their reliability issues.

The 2015 Formula One World Championship could come down once again to an inter-team rivalry between Lewis Hamilton and Nico Rosberg.

Williams have potentially closed the gap to Mercedes, powered by the same power-unit Williams will be hoping to achieve a Grand Prix victory in 2015 after showing impressive pace throughout testing.

It’s difficult to see just where both Lotus and Force India are with their cars. Lotus have clearly made a step forward after ditching Renault for Mercedes this year, but with a brand new car they will be playing catch-up.

As will Force India who have only had two-and-half days on track with their new car after missing the first two winter test sessions due to the late development of their 2015 machine. It has shown good reliability but hasn’t been able to show it’s performance.

Ferrari appear to have also vastly improved. Their engine and car looking quicker than last year with both Sebastian Vettel and Kimi Raikkonen enjoying the new car. They could prove to be well placed to fight for the best of the rest position alongside Williams.

Sauber also look to be benefiting from the new Ferrari power-unit and appear to be heavily involved in the mid-pack mix. They will be aiming to earn a point in 2015.

Red Bull Racing look to still be struggling with their Renault power and look likely to have slipped down the pack, behind both the Williams and Ferrari teams.

Sister team Toro Rosso are probably content with their current position, coming through winter testing with two new rookie drivers.

Both Max Verstappen and Carlos Sainz appear to be settling in well and have both impressed.

The 2015 grid looks set to be complete by the inclusion of Manor-Marussia, who have had their entry for the new season approved by the FIA.

The team still need to produce a car that meets 2015 regulations before they will be able to join the paddock in Australia.

With less than two weeks to go, let the countdown commence!
