Curbside Classic: 1947 GM PD-3751 "Silversides" Greyhound Bus – The First Modern Diesel Bus

This GM bus revolutionized the industry, and set the template for all over-the road buses to come: forward control, rear transverse diesel engine, the famous fluted aluminum “Silversides” cladding, semi-monocoque construction, high floor and underfloor luggage compartments. But its wildest feature was not replicated: a four-on-the-tree shifter and its mechanical linkage back to the non-synchronized gear box; something had to be left to improve. Let’s check it out and delve into the history and workings of its legendary Detroit Diesel 6-71 engine, which first made its appearance here.

  • Sgeffe Bronco looks with JLR “reliability!”What’s not to like?!
  • FreedMike Back in the '70s, the one thing keeping consumers from buying more Datsuns was styling - these guys were bringing over some of the ugliest product imaginable. Remember the F10? As hard as I try to blot that rolling aberration from my memory, it comes back. So the name change to Nissan made sense, and happened right as they started bringing over good-looking product (like the Maxima that will be featured in this series). They made a pretty clean break.
  • Flowerplough Liability - Autonomous vehicles must be programmed to make life-ending decisions, and who wants to risk that? Hit the moose or dive into the steep grassy ditch? Ram the sudden pile up that is occurring mere feet in front of the bumper or scan the oncoming lane and swing left? Ram the rogue machine that suddenly swung into my lane, head on, or hop up onto the sidewalk and maybe bump a pedestrian? With no driver involved, Ford/Volkswagen or GM or whomever will bear full responsibility and, in America, be ambulance-chaser sued into bankruptcy and extinction in well under a decade. Or maybe the yuge corporations will get special, good-faith, immunity laws, nation-wide? Yeah, that's the ticket.
  • FreedMike It's not that consumers wouldn't want this tech in theory - I think they would. Honestly, the idea of a car that can take over the truly tedious driving stuff that drives me bonkers - like sitting in traffic - appeals to me. But there's no way I'd put my property and my life in the hands of tech that's clearly not ready for prime time, and neither would the majority of other drivers. If they want this tech to sell, they need to get it right.
  • TitaniumZ Of course they are starting to "sour" on the idea. That's what happens when cars start to drive better than people. Humanpilots mostly suck and make bad decisions.
