Haas team principal Gunther Steiner has praised Ferrari for what they accomplished in the first winter test at Barcelona.
Ferrari were the only team other than Mercedes to clock up over 2000km at the Circuit de Catalunya, with Sebastian Vettel and Kimi Raikkonen racking up 267 and 201 laps respectively over the course of the first four days of testing.
Haas, who have struggled massively with reliability in the past, finished fourth in the most laps completed standings with their Ferrari engine, and Steiner believes the Scuderia deserved plenty of credit.
“The engine and gearbox here, we had almost a flawless test with the same engine – we never changed engine,” said Steiner.
“We had twice an electronics problem but it was a software problem, nothing big mechanical. They [Ferrari] have done a fantastic job in my opinion.
“To come out here with a new engine, a complete new engine, and be this reliable, it is amazing. If you look at the other ones around, and they are no dummies, they have quite a few issues.
“So from last year to this year [Ferrari] stepped up a lot and it is very good.”
