Nico Rosberg says he's aiming to maintain his winning momentum for as long as possible into this season but feels it was never something he expected off the back of his three wins at the end of last year.
The Mercedes driver has enjoyed a flawless start to the 2016 F1 World Championship having controlled to four wins in four races, plus two pole positions and two fastest laps.
Combined with his title rivals' troubles Rosberg holds a substantial 43-point lead on Lewis Hamilton – having further extended his largest-ever points advantage over his team-mate last time out at Sochi.
Despite Mercedes' dominance with the W07 on his side of the garage – and the ongoing reliability issues on Hamilton's car – Rosberg says the winning run isn't something he could have predicted and is keen to make it last as long as possible.
“It's not something I could have expected - winning the first four races of the year,” Rosberg said. “It's been a great start but I'm just enjoying the moment and the form I'm in, doing my best to keep it going and hoping I can carry it through to the end of the season.
“Sport is all about ups and downs and being mentally prepared to bounce back stronger when they come. With a season this long you have to just take things race by race. There are 425 points still up for grabs - and anything can happen yet.”
Rosberg's indifferent start to last season was righted with a first win of the season at the Spanish Grand Prix, his maiden victory in Barcelona, and is confident if he can rediscover the same feeling with the car from Russia he'll be targeting a fifth victory.
“Next up, it's Barcelona. I got my first pole and win at this circuit last year and I'm connecting really well with the car at the moment, which is great as it gives you this awesome confidence to push the limits,” he said. “So, I'm excited for the weekend and no doubt a big battle ahead.”
If Rosberg does finish on the top step of the rostrum in Spain he will extend his consecutive wins streak to eight, counting back to 2015's Mexican Grand Prix, which will give him the outright second-longest run in F1 history and one behind the all-time record set by Sebastian Vettel with Red Bull in 2013.
