Vettel buoyed by progress
Red Bull's Sebastian Vettel believes he is seeing improvements in his car ahead of the Chinese Grand Prix this weekend.
The defending world champion competed in the practice sessions in Shanghai on Friday, as he looks for his first win of the season following a slow start.
Vettel dominated proceedings from the very first green light in Melbourne last term but has not had everything his own way in the current campaign, and he sits in sixth place in the World Drivers' Championship after two races.
The likes of McLaren and Mercedes have leapfrogged the Milton Keynes-based outfit in terms of qualification speed and now Red Bull are determined to make up ground.
Vettel has admitted his car still needs work but believes his team are making progress, as they go in search of their first win of the season this weekend.
The German told Sky Sports: "I think I felt a bit more comfortable today, a bit more together so we'll see. It's a bit tricky now to say if we're going to be competitive. It's fairly close but I think McLaren is still very quick in all conditions and on all fuel levels."
