World champion Sebastian Vettel says with sweeping rule changes in F1, he has no expectations going into the 2014 season.
The four time world champion joined new team mate Daniel Ricciardo on Tuesday morning at the first pre-season test at Jerez in Spain to launch the RB10 - the latest Adrian Newey creation to roll out of Tilbrook.
With new engines, aerodynamic rules and fuel consumption, Vettel is reserving his judgement for the season ahead until he has had more time in the car.
“It’s difficult to have expectations,” he said. “We just need to understand the car and what it needs.
“At the moment, expectations are low, but hopefully we have a good car, and we want to race where we have done in the last four years.
“It has been difficult to prepare for the unknown, but you try and understand as much as possible before you start.
“There’s some guessing, but we will find out after the first couple of tests and the first race.
“We will have to adapt our driving style, look after the car and the fuel. It’ll be different to what we’re used to, but it’ll take time to adapt.”
Ricciardo, who replaces Le Mans-bound Mark Webber, admits he wants to come away from his first season with Red Bull with victories under his belt.
He said: “I want to finish the year with some victories, but I want to leave everything on the table - that’s my aim.
“This season is going to be very challenging, but very exciting. It’s something I’ve been looking forward to for months - my whole life really. For me, it’s another big step in my career. It’ll be challenging for everyone, but we’re ready and excited.
It’s a good time to change team and come in with all the changes in 2014. It’ll level things out and give me the best chance possible to shine, I hope.
After Webber and Vettel’s fractious relationship fell apart last season, Ricciardo hopes to have a more peaceful time with his new team-mate than his compatriot did.
He said: “I’m really looking forward to racing alongside Seb. He’s achieved so much in so little time.
To be a four time champion is an amazing thing and I have a lot of respect for that and him.
“I want to try and get some success, but to do that, I have to respect him and go from there.”
The first race of the season gets underway in Melbourne, Australia, in March.
