This subject came up in the comments underneath my review of the Bugatti T40. [If you haven't come across dogboxes before, they're explained (or at least chewed over) here.] Googling to shed some light on the debate, I came across this hair-raising video of BMW supercar with a straightcut dogbox eating up the competition, sounding like something out of Star Wars. My take is that while straight cut spur gear are weaker (in principle), they can be constructed to be enough bigger in the same space that they end up stronger (in practice). Perhaps TTAC’s Best and Brightest would care to comment?
