So, the arguments in the topic why Mclaren cannot become an engine manufacture are summarized as follows:
- It is too costly
- They do not have the expertise
Argument 1, costs.
I think it can be divided into two aspects:
1.1: costs to setup the facility, purchase the engineering equipment, hire the staff, build a factory etc etc. This expense is immense indeed.
1.2: costs for continuous R&D. Still a huge amount of money. I believe I read somewhere that Mercedes spent some 500 million euro's into R&D as of 2011-2014 to develop their engine. That amount will drop significantly of course, and a large sum should be covered by the customer teams who basically are paying now for this R&D.
Argument 2. expertise
They currently have no experience in building engines. As mentioned, Mercedes also outsourced the engine building for a part (?). Mclaren could acquire such a company which has experience (Costworth? etc). In addition, they can hire staff from Ferrari, Mercedes, Renault, Honda etc.. it is quite common in F1 to chase employees of competitors.
Concluding:
Expertise should not be an issue, there is expertise available in the market, or in other company's.
The conclusion then is that money is the obstacle. Although the budget's are tight now without a title sponsor for Mclaren, I do believe they have enough liquidity to fund big investments (just an assumption). With external investors, loans, etc etc, it should be possible to make such an investment. The question then is;
- What benefit does it bring from a competition point of view? Will their own F1 engine be competitive? And when? Would it take 4 years to develop?
- Can the incurred costs be compensated by benefits to their road-car section development, or perhaps even customer teams with a 'mclaren engine'?
If their engine proves to be good, I'm sure they can tie a know with a smaller team, also increasing their influence in F1, bigger bargoning power, perhaps some influence on one driver this team should hire (Vandoorne etc). It would also provide them with a strong source of income. I'm not sure how relevant the F1 R&D would be for their road car engines...
All in all it seems quite complicated, but on first sight, it seems to be a route Mclaren should want to explore to assess the idea.
