Grosjean "laughing" about run of bad luck

The Haas driver had only just left the garage at the start of qualifying when smoke started pouring from the back of his Ferrari-engined VF-18.

He stopped immediately and was wheeled back to the garage, where his session ended before anyone had even set a laptime.

Haas described it as a "power unit failure" that was being investigated.

It means Grosjean, who along with Williams driver Sergey Sirotkin is yet to score a point this year, will start Sunday's race last while teammate Kevin Magnussen lines up 11th.

"I'm getting the bad luck for next season and maybe even [beyond]," Grosjean told Sky Sports F1.

"It's a tough series [of bad results], everyone is taking it as good as they can.

"We're laughing about it because at one point that's the only thing you've got to do."

Grosjean has endured a dismal season, which started with a retirement in Australia after a Haas wheelgun error denied him a possible top-five finish.

His car shed bargeboard parts in Bahrain, dropping him to 13th, and he finished 17th in China after an ill-timed safety car.

Grosjean then retired from successive GPs in bizarre fashion, spinning under the safety car in Azerbaijan before causing a big first-lap crash in Spain.

Haas was uncompetitive in Monaco after compromising performance by removing the fragile bargeboard components for the street race, while Grosjean's bizarre run continued when he hit a marmot in Friday practice in Montreal.

Grosjean said the failure in qualifying was "up there on the podium" for bad luck this year but said the performance of Haas's upgraded car in Canada was a silver lining.

"The positive is the car feels really good with the upgrade, we had a really good pace through practice," he said. "I knew I could be best of the rest today."
