I was told that the amount of air polution created from producing one set of Hybrid batteries is more than a typical suv produces in 10 years!

Tell that to the tree huggers!  They are making the ozone worse one battery at a time!

Further to what Steve mentioned, I  don't know how accurate this is now, but I read a few years ago that one takeoff of a commercial airliner, created as much or more air polution as 900 cars being driven 24 hours a day for a week!

pcmenten, it says the W8 is two 15 degree V4s, with a 72 degree angle between them. Do you take this to mean 72 degrees between the insides of the V4s, or 72 degrees between the centers of the V4s ? Either way, it doesnt come out to an " even " angle overall.


Yes, I took that to mean that it was two 15 degree V4s. It would be a straight 4 ,but to get the cylinders closer together they offset the cylinders slightly, staggering them. Then they joined the two four cylinder engines at the crankshaft.

A V8 is two straight 4 cylinder engines joined at the crank at a 90 degree angle. The W8 is two 15 degree V4s joined at the crank at 72 degrees.

Here’s a picture of the cylinder layout for the W12 engine which is similar to the W8.  Just a different number of cylinders.  And also a picture of the W8 crankshaft with rods and pistons.

Looks like a pair of their narrow angle V6's on a common crank. Bet that's an interesting cylinder Head!

Short skirt pistons, looong connecting rods. It must have wedge shaped piston tops. That crank must look pretty strange.

Thanks for the pix, Ted. Now I see how they stagger them to make them fit a 15 degree angle.
