BMW 507: engine and chassis

I started this one, partly as an easy build to relax while pondering the bodywork on the Alfa, and partly to enter a build-off for roadsters run by The New Modeler's Club Facebook page, which has an August 1 deadline.

 

A gorgeous car, with a lovely 3.2 litre aluminum V8; it was very advanced for its day but doesn't have the public recognition of its immediate competitor, the 300 SL. Hard to compete with those gulling doors, I guess.



The carbs in the kit are pathetic. I found a pair leftover from the Revell 283 Parts Pack kit; they are not quite right, with 2 bbl each instead of 1, and with smaller air filters, but they will do.



I added an aftermarket distributor and fuel lines. Fuel lines are excessively fat but that's OK.



The chassis, while using a solid rear axle, did have torsion bars front and rear, with a Panhard rod at the back; it is arguable that a well-located solid axle is at least as effective as the low-pivot swing axle Mercedes hung on to until the last of the 300 SELs in 1973 or so. 



The engine is a lovely little item; however it made less power than the smaller engine in the 300 SL. Not sure how that happened. In the end BMW lost money on every one of the 252 cars made, and barely escaped bankruptcy.



On to the interior and body. I am still working on paint; the 507 came in a range of colours and the usual red, white, black and silver are common. But there are pictures online of lovely '50s pastel greens and blues, which may or may not be original; and at least one car has wonderful deep burgundy leather. Stay tuned!
