What they said
Force India
While Force India revealed the VJM11, they were quick to point out that their name, and therefore probably the name of the car, has a "greater than 50% probability" of changing before the opening race of the season next month in Melbourne.
Chief operating officer Otmar Sazfanauer said: "We haven't quite decided (the name) and it also needs to go through the formal approval progress. There is a probability it will change before the first race."
The team also revealed the cost of fitting the new-for-2018 halo device, which they reckoned was. "in the hundreds of thousands if not million-dollar mark."
"Expense-wise, it's huge, because we had to do a new chassis," Andrew Green, Force India technical director, explained. "We wouldn't have anticipated doing a new chassis this year, given the amount of changes that we made last year, which was huge for a new regulation change. For a team like us, we'd always look to try and get two years out of the chassis if possible.
"In that respect it cost us a huge amount to redevelop and redesign a new chassis, it's in the hundreds of thousands if not million dollar mark to put that halo on the car. It was a huge challenge; for a team like us it was massive."
