Re: Another BMW marketing-engineering-legislation quandary - Pedestrian Protection
Just tell me: If a Honda or Merc hits a pedestrian at 90km/h, will it kill him? Or only a BMW will?
michaeltan said:I mentioned a quandary before, that BMW marketing for its inline-6 I suspect is compromising the packaging of their cars, where a V6 would have given them much more room and engine toughness (no need so long crankshaft) .... let's take a look at their overhangs now.
As you probably already know, the 3- (E90) 5- (E60) series have cored VERY badly in terms of pedestrian protection in event of collision.

So, many manufacturers, including Toyota (GS, Camry, IS), Honda (civic, Legend), Nissan, Renault, Alfa (new 159) have designed their new cars to improve on the pedestrian safety perspective, by:
1) increasing the length of their front overhangs to create a buffer zone for pedestrian protection in front of the car, and
2) by using a 4-cylinder or a low profile V6, they have created some space between their engine bonnet and the engine itself to create a buffer there also. (see footnote also, below)
But both these features are opposite to BMW's `virtues'.
1) They boast a short front overhang saying that it promotes handling, but it kills pedestrians since the pedestrian will hit the hard engine without the luxury of a buffer zone of a longer overhang.
2) they market their I6 engine as the greatest form of engine, but it kills pedestrians as a I6 engine is fundamentally taller, and it is impossible to create that buffer zone (eg. the M3 E46 actually had to tilt the I6 to fit their engine bay!)
How can they overcome the quandary? Or, will they continue to compromise pedestrian safety if they decide that their customer demographics do not care too much about pedestrian safety in relation to driving enjoyment? Or, hopefully, is there a link anywhere which will show us a preview of BMW's engineering principles they will employ to solve the problem?
