I never thought I'd find it but I figured VW MUST have researched and prototyped a pushrod flat 6 sometime in their history. I've been googling on this subject for sometime, but never quite hit the right combination of keys until this morning (literally after a dream last night). For those of you who know all about this engine, please excuse this if it's redundant, but it's just too tempting to look at this engine as a potential VW swap.. afterall.. it's "Factory".
VW was developing the WasserBoxer 4 cylinder, and had a 6 cylinder variant also in the works. Market Research suggested that it was not worth the tooling/ development for the 6 cylinder, so VW sold the design to Oettinger. The Vanagon experts can chime in but as I understand it, Oettinger built a "Tuner" synchro Vanagon, and offered two versions of the six.

I can't speak to this much newer water cooled engine, but if I remember correctly Porsche design and test various prototype variants of a six cylinder engine for the original 911 six in the early 1960's including a pushrod version. I think there are photos of these in "Excellence Was Expected".

I think there are photos of these in "Excellence Was Expected". I've seen that engine which was a Porsche design, but this 6 was VW "proper". The power outputs were pretty low for the displacement (one was/is 3.7 liters, but under 200hp). I think they literally copied and pasted the 4 cylinder's head design with torque and emissions as the primary goals. |
