Mark Webber has predicted that all the grand's prix this season could be 'pretty interesting'.
In addition to the arrival of Pirelli, as the sole tyre supplier, drivers and teams will also have to cope with the returns of KERS – Kinetic Energy Recovery Systems – as well as a moveable rear wing designed to aid overtaking.
Webber believes this should help spice up proceedings: "I think every grand prix this year has a chance to be pretty interesting," the Aussie told Reuters
. "We don't know quite yet how the races are going to unfold with strategy and how the rear wing's going to work and KERS (Kinetic Energy Recovery System) and that sort of stuff.
"When you get down to the nitty-gritty of actually what's going to happen on Sunday afternoon and how exciting it's going to be, we don't quite know yet.
"But all things we've seen so far are indicating it is going to be pretty unpredictable and for the neutral that's a good thing."
Meanwhile, Webber, who fractured his shoulder at the end of last year in a mountain bike accident, added he is in tip-top shape for F1 2011: "It's all good. I've been doing lots of (bike) riding, being out on the bike training and doing stuff.
"I'm in pretty good nick actually, not bad for an old boy, so ready to go again," added the Red Bull man.
