Sergio Perez says every time he gets behind the wheel of the Force India VJM08 car he finds new improvements and is yet to understand the car's full potential ahead of the Malaysian Grand Prix.

The Mexican driver brought home his Force India car in tenth place at the Formula 1 season opener last weekend, despite having severely reduced testing time with the VJM08 due to the team's pre-season financial issues. The 25-year-old says it is a new learning experience each time he drives the 2015 car and believes the team can still do more to be competitive.

"I am looking forward to going racing again after our first run in Melbourne," Perez said. "We are still learning a lot about the full potential of the VJM08 and every time we hit the track we are going to find some improvements.

"We are aware of the work needed to make our car more competitive, but we also know it is going to take time. The car feels really promising but it needs development and I look forward to getting some upgrades soon."

In 2012 Malaysian Grand Prix the Mexican driver claimed his first career Formula 1 podium by finishing second while driving for Sauber. The 25-year-old holds the circuit as an important place in his racing career and is hopeful to enjoy more success in Malaysia.

"Malaysia is a very special place for me," It is where I got my first podium in Formula One, in one of the best races of my career in 2012, so I will always have happy memories about this circuit."

Perez is also aiming to banish the disappointing memories of last year's race when he failed to start the Malaysian Grand Prix due to a gearbox failure.

"The track is really interesting and the three sectors each have their own character," he added. "The track is physical but it has some very technical parts as well. You also have some very long straights at the end of the lap that offer a lot of opportunities for overtaking."

On top of the tricky circuit Perez is also wary of the adverse weather conditions Sepang can throw up and feels the team will need to be flexible with its strategy in case of any sudden downpours.

"The weather always makes it interesting," Perez explained. "When you are racing in Sepang it is something that is always in the back of your mind, because you know a sudden rainstorm can throw up some unexpected strategies and opportunities you can exploit."
