Magnussen: Some things good, some things not so

Kevin Magnussen has revealed "some things were good, some not so" for Haas in the post-Spanish Grand Prix testing in Barcelona.

Magnussen finished in P7 in Barcelona at the weekend, where it mattered, and helped "gather a lot of data" for Haas in the in-season testing at the Circuit de Catalunya.

The Dane recorded a quickest lap-time of 1:18.101 and that was 2.3 seconds slower than the fastest of the day, but the Haas driver confirmed they were not taking part to set a best lap-time.

"I was happy to get a lot of laps on a test like this straight after a race weekend," Magnussen explained. "It's really useful to be able to evaluate everything back-to-back.

Magnussen went onto say how useful the two-day test was for the team, who secured a double-points finish at the weekend.

"Some things were good, some not so, but it's testing, so we're trying stuff that's not necessarily going to make you faster - you're just getting information to help you make progress," Magnussen concluded.
