Formula 1's unplanned April calendar gap means Racing Bulls will bring an upgrade to the Miami Grand Prix that will then immediately be superseded after just one race of use, rather than the planned three.

The team was planning to bring its first major upgrade of the season to round four in Bahrain in mid-April, then introduce its next package for round seven in Canada in late-May.

The loss of both the Bahrain and Saudi Arabian races means that 'Bahrain' package will debut in Miami instead but then the Canada package remains scheduled for introduction just one round later.

"We had a pretty decent upgrade planned for Bahrain which, of course, we will see in Miami," explained team principal Alan Permane.

"We had another upgrade planned for Montreal, so we will have a sort of quick double hit there.

"There's no way to bring them both [to Miami]. The Montreal one we can't bring earlier, so it's a slightly strange situation where we'll bring a quite a decent upgrade and new component, and then almost replace it straight away. That's just the way the calendar has fallen."

The calendar change at least means Racing Bulls will have a more plentiful supply of the parts for its initial upgrade in Miami then would have been the case in Bahrain.

Having the cars back at base through April has allowed Racing Bulls to do "some unplanned work on the chassis", Permane added, though the "actual cycle of upgrades is pretty well planned".

Racing Bulls has scored points in every race so far this season - headlined by Liam Lawson's seventh places in both the sprint and grand prix in China - and is seventh in the constructors' championship, just two points behind senior team Red Bull.

"What I know we've got in the pipeline will lift us certainly a little bit more into that midfield battle, whereas at the moment, we're more to the middle-to-the-back of it," Permane said.

He reckons the car "works well" and "doesn't seem to have any particularly nasty traits about it".

"We just need more load, which is what we're bringing," he added.
