The “Fast & Furious 6″ Twitter account – no doubt staffed by Vin Diesel himself (ha!) – has released a suspiciously candid photo of director Justin Lin and stars Vin Diesel and Paul Walker on the Euro-set of the new sequel.

“I dunno, man, I gotta say, some spit in the coolant does make the car thermo purr”, says Diesel, as he glances Lin an all-knowing look.

“Your inane comments should be classified XXX – concealed forever, Vin”, Walker laughs, his short blonde locks dancing in the wind.

“When do we get paid again?”, Lin jumps in.

Dwayne Johnson, Gina Carano, Jordana Brewster, Tyrese Gibson, Michelle Rodriguez, Joe Taslim, and Luke Evans star in the gasoline-energized sequel to “Fast Five”, hitting cinemas next May.
