Sir Snipes Posted October 10, 2018 Share Posted October 10, 2018 ZX and its passive rear wheel steering. Unusual at the time: since adopted for many other models by several manufacturers iirc. I thought the ZX's sliding rear seat was a brilliant innovation too, but later found it was not a new thing.Passive rear steer wasn't so unusual, Porsche made a big deal of it with the 928 in the 70s. It's a part of just about any chassis design due to the inherent flex in rubber bushings, usually the intention for slight toe-in and negative camber under load. Makes me wonder what the earliest example of active rear steer was though? Link to comment Share on other sites More sharing options...
Guest Conan Posted October 10, 2018 Share Posted October 10, 2018 I also find BMW E36 rear brakes a bit of an odder than standard design, the rear calipers are pretty standard, but don't have a handbrake mechanism. Instead they use the inside of the disc as a drum handbrake, complete with shoes and all supporting drum hardware. My ex-Nissan engineer friend told me that all Nissan with rear disc brake had that arrangement until very very recently because the R&D didn't bother to learn the disc handbrake cable design.

Bianconeri Posted October 10, 2018 Share Posted October 10, 2018 Peugeot spark extenders, why not use a longer cable? The Renault 14 may have used those too, I remember you needed a very long spark plug socket plus the wretched things were miles over at the back of the engine due to way it was canted backwards.

The Reverend Bluejeans Posted October 10, 2018 Share Posted October 10, 2018 Alfasud. Tappets adjusted through a hole in the cam between two slim cam lobes operating on the same bucket - an Allen screw in the centre operated on the valve tip. Such an elegant solution making valve adjustment incredibly easy. spartacus, Barry Cade, Talbot and 1 other 4 Link to comment Share on other sites More sharing options...

quicksilver Posted October 10, 2018 Share Posted October 10, 2018 I’m sure junknsn will know it’s was used firsts is the 1907 crossly trumpet 7 side valve but the vr6 , v6 with a single cylinder head looks fucking weird to me. Even weirder than that, VW also made a VR5. Yes, a V engine with an odd number of cylinders. Renault 6 weirdness has already been mentioned but for one thing. It has a starting handle but we can't figure out where the heck it's supposed to go. Putting it in the front of the car would insert it into the gearbox, and for it to work on the front of the wrong-way-round engine it would have to be inside the car going through the bulkhead, which is too stupid even for Renault.

Lacquer Peel Posted October 10, 2018 Share Posted October 10, 2018 The VR design was cribbed from Lancia but even Lancia wasn't strange enough to try a 5 pot version. Barry Cade and cort16 2 Link to comment Share on other sites More sharing options...
andy18s Posted October 10, 2018 Share Posted October 10, 2018 We spotted an old racing car at Shelsey Walsh which had a huge brake disc on the back of the diff rather than brakes on the rear wheels. 48.pngreducing unsprung weight/halfing the weight with only 1 caliper and putting it on the the centre line of the chassis....very clever Link to comment Share on other sites More sharing options...
rml2345 Posted October 10, 2018 Share Posted October 10, 2018 So are we all in agreement that transverse leaf springs and drum in disc handbrakes aren’t unusual at all now ? Volvo used the drum in disc handbrake setup as well on 200/700/900/850 and probably more so no, pretty common I'd say... Speaking of Volvo 850s, the semi independent rear suspension seems quite odd.

quicksilver Posted October 10, 2018 Share Posted October 10, 2018 Not a car engine but the Commer TS3 was pretty weird. Two stroke, three cylinders, six pistons, no valves and a big supercharger.

AMC Rebel Posted October 10, 2018 Share Posted October 10, 2018 I can't find a thread for this... Cars with odd ways to do mechanics, engine, drivetrain, electrics etc. show them here. Let me start with Peugeot running a belt around the corner. Ha! saw this topic and my first thought was the Peugeot belts - I remember seeing one in a scrapyard and being amazed - and thinking it was a brilliant solution tho the transverse engine cooling issues that Minis etc al had. That was before electric fans made it easy of course. Link to comment Share on other sites More sharing options...

cros Posted October 10, 2018 Share Posted October 10, 2018 Roland LLoyd seemed to favour odd cylinder arrangements, theres usually an extra pot sticking out somewhere, even on the earlier 'single'. Lots of effort to avoid pre-mixing oil, but a feeble thing all the same. mercrocker 1 Link to comment Share on other sites More sharing options...
