Added 3d render of crankshaft; removed reqdiagram Egmason (talk) 08:26, 18 May 2010 (UTC)[reply]
This is not representative of of a cross plane crankshaft in an S4 or V8. Typically, an inline four with a 90-crank uses two pairs of opposed big ends at 90º to each other. That is 0º, 180º, 270º, 90º. It's like two Triumph engines at 90º to each other. The YZF R1 which is mentioned in the text uses 0º, 90º, 270º, 180º - an opposed pair in the centre but firing like a pair of Ducati twins. Sir smellybeard (talk) 17:11, 4 December 2012 (UTC)[reply]

Porsche Flat 8

No mention is made of the Porsche 908 Flat 8 engine. Later variants of this used a crossplane crank to gain the same effect as a flat crank V-8.Sir smellybeard (talk) 17:19, 4 December 2012 (UTC)[reply]
