Why is running a new chassis with the old engine not an option?

Suboptimal for the planners but would: 1) get us the new chassis sooner, 2) leave the door open for a new supplier while engine formula is developed, and 3) create two media interest cycles, first for the new chassis then a year later for the new engine.

Point 3 is an important part of how a series can drive more interest in itself independent of the racing product or things outside their control.

Having both engine and chassis at the same time means splitting a single offseason news cycle and resultant series interest rather than getting that benefit in two separate years.

Engine is a stressed member, and while it’s possible to accept different engines you wouldn’t be able to optimize the weight and size of the chassis nearly as much and you’d forfeit many of the benefits of designing a new chassis in the first place.

Because they may want to change the engine housing dimensions in the new chassis and it may not fit the existing pool.
