Horner impressed by Lotus and Sauber
Forget the 'big three' -- Christian Horner has admitted teams other than Red Bull, McLaren and Ferrari made the "strongest impression" on him last week at Jerez.
"Lotus and Sauber left the strongest impression," the Red Bull chief said, according to Germany's Auto Motor und Sport.
"All the others are still difficult to assess," added Horner.
The German magazine's correspondent Michael Schmidt said the new grey Sauber had Nico Hulkenberg "smiling" all week as the opening test at Jerez unfolded.
"Eyewitnesses say the C32 is the best car in the field in fast corners," said Schmidt.
Swiss newspaper Blick's veteran correspondent Roger Benoit, meanwhile, quoted Hulkenberg as confiding to his Sauber colleagues: "Guys, this car goes like the devil."
