![]() Philippa,
I agree that the Fighter has a unique chassis and probably may have a uniquely configured air con system , but I suspect the air con will be based around off the shelf components matched to suit the requirements of the Fighter, not bespoke down to the ECU and sub components. That would be farcical economically and something simply not worth doing. Most large scale auto manufacturers use common components configured to their specific requirements but often shared amongst several brands/marques. A classic example (not air con) is the half shaft (drive shaft) off a Porsche 928. It is more than £450 off the shelf from Porsche and is a direct swap for the same item used on a Ford Granada of the same era (price £195). All made by GKN. Similarly air-con units largely come from 3-4 global suppliers. Bosch supplies so much to the auto industry one has to ask the question, what apart from body and chassis design do the car makers actually do (lots really). Even engines and gearboxes are routinely shared these days (Borg Warner / Getrag / etc, or Alfa/Fiat/Vauxhall/Saab with diesels or even BMW Mini/Peugeot/Citroen diesels to name a few). Everything from ABS and braking systems to other sub-systems are designed and produced by third parties. Indeed it is a strength that such outsourcing of common systems is used, especially for Bristol - makes it better for us who make the time and effort to keep them going. My 406 will have a latest model Dana Spicer rear axle and modern front disc calipers, plus other nice shiny 3rd party stuff added for convenience and ease of maintenance - including a fully integrated off the shelf air con unit. As to crash worthiness it is of great importance that energy is absorbed by the structure as much as possible instead of the people inside. Rather than blame the lack of available airbags (designed to help keep moving body parts from too much acceleration and impact damage), the issue you raise about a multiple car pile up is more related to the subsequent lack of impact (energy) absorption by an already crashed car by another impact. This is a catch 22 and unfortunate. Although having said that the basic cell structure of most moderns remains pretty strong even after front and rear impact absorption. Fewer deaths occur due to high speed (30-50mph) impact than say 20-30 years ago (pro-rata). Even better still are injuries due to impact of body parts inside the car. The Bristol (V8's) has excellent rear impact absorption (relatively weak (soft) structure) attached to a solid structure and similarly same at front above chassis line and before engine. Side impact is good too as long as the impact is below knee height until it hits the inner chassis rails. In any event, the guy in the heavier object always comes off (almost always) better than the guy in the smaller one. A V8 Bristol weighs in at 1700kgs about the same as a modern BMW 5 series or smaller 7 series. |
