Romain Grosjean is apparently becoming more and more frustrated with the situation at troubled Lotus this season.
Before the season, video footage circulated on the internet depicting the Frenchman slamming his hand on a tool bench as the serious problems with the new E22 car became clear.
Grosjean played that down. "It was a joke with the mechanic and a camera took the picture and it went everywhere," he explained at the time.

But now at the post-Bahrain grand prix test, after teammate Pastor Maldonado suffered Renault "power unit-related" issues on day one, Grosjean's mileage on day two was limited to just 16 laps, again with "power unit failure".
The 27-year-old is sounding increasingly frustrated.
"I hope Renault will improve in terms of reliability and performance," he is quoted by France's Auto Hebdo, "because today was not acceptable.
"We are expecting more," Romain Grosjean added. "Renault has said that in China and Barcelona there will be changes, so we wait."
