How Automakers Decide What to Build Next

Ask someone why a car company does not build the car they want and you will usually hear something about cowardice, or bean counters, or a design committee. The real answer is duller and more interesting: the car was modelled, and the model said no.

Product planning is the discipline that turns a brand’s ambitions into a sequence of funded programs. It is part market research, part manufacturing logistics, and part capital allocation, and it runs on a clock that is wildly out of step with the news cycle.

The plan is a portfolio, not a list

Every automaker has more ideas than money. The planning function’s job is not to pick the best idea; it is to assemble a set of programs that, taken together, cover the segments the brand needs to be in, use the factories it has, share the platforms it has already paid for, and produce an acceptable return.

That framing explains a lot of behaviour that looks irrational from outside. A boring crossover gets funded while an exciting coupe dies, not because executives prefer crossovers, but because the crossover contributes volume to a platform that three other vehicles already use, and the coupe would need its own body shop tooling for a fraction of the volume.

The unit of planning is the program: one vehicle, one plant assignment, one launch date, one business case.

Segmentation, and the myth of white space

Planners divide the market into segments defined by size, body style, price band, and buyer intent. The classic opportunity story is “white space” — a segment with demand but no competitive product.

White space is real, but it is usually empty for a reason. Sometimes the reason is that the segment is too small to amortise tooling. Sometimes it is that the segment exists only at a price point where the product cannot be built profitably. Sometimes it is that the segment is an artefact of how the data is cut, and the customers actually shop one segment over.

The test a planner applies is not “is there a gap” but “can we occupy this gap at a volume that pays back the investment, at a price the segment will bear, without stealing sales from our own products”.

That last clause matters more than outsiders expect. Cannibalisation is a real cost. A new model that takes 60 percent of its volume from an existing model in the same showroom adds cost and complexity without adding much profit.

Take rate: the number that decides the options list

Take rate is the share of buyers who choose a given configuration — a trim, an option pack, a powertrain. It drives almost everything downstream: what gets built, what gets stocked, what gets engineered at all.

A feature with a 4 percent take rate is often not worth engineering, because the cost of validating and manufacturing a low-volume variant is spread over very few units. A feature with a 70 percent take rate is nearly standard equipment, and gets priced as such.

This is why the options list on a new car often looks arbitrary. It is not a menu designed for you; it is the residue of a set of forecasts about what enough people will pay for.

The gates

Programs move through staged approvals, and each stage releases more money. The names differ by company, but the shape is consistent: a concept or strategy phase, a pre-program phase where the package and the business case are fixed, an engineering phase where tooling is ordered, and a launch phase.

The important property of a gate is that it is a genuine option to stop. Companies are much better at killing programs at gates than journalists give them credit for, because the cost of continuing rises sharply at each one. Ordering stamping dies is irreversible in a way that a design study is not.

Two consequences follow. First, most cancellations happen early and quietly, so the public only ever sees the survivors and concludes that nothing is ever cancelled. Second, the further a program gets, the more expensive it is to change its proportions — which is why late-stage concepts look so conservative.

Why platforms decide more than brands do

A platform is a set of shared hard points: floor, suspension pickup points, powertrain mounting, electrical architecture, and the crash structure that ties them together. Everything a designer can do sits on top of those decisions.

That is why platform strategy is the real product strategy. If a brand’s next four vehicles share a platform, those four vehicles will have similar proportions, similar interior packaging, and similar cost structures. Differentiation happens in the surfaces, the calibration, and the trim — real work, but bounded work.

Electric platforms have loosened one constraint and tightened another. A flat floor and a compact drive unit give designers more freedom in proportion than an engine and a transmission ever did. But the battery pack is expensive, heavy, and shared, so the cost of a program is now dominated by a component that planners cannot style their way out of.

The arithmetic that kills good ideas

Put the pieces together and the pattern is clear. A program dies when the combination of segment volume, achievable price, platform amortisation, cannibalisation, and regulatory cost fails to clear the company’s hurdle rate.

None of those inputs is about whether the car would be good. A planner can believe a car would be excellent and still recommend against it, and be right.

Which is why the interesting question about any future product is never “do they have the guts to build it”. It is: which platform would it share, which plant would build it, what volume does the segment support, and what does it take from something else in the showroom? Answer those and the plan stops looking like a mystery.
