Doctor 540i or:
How I Learned to Stop Worrying and Love the V8
I used to look down my nose at this engine configuration.
Sure, my opinion of them was colored by my thoughts concerning the perennial American attachment to big whacking pushrod lumps (which are certainly effective, done correctly), but I was wrong to let my views on the evergreen Small Block Chevy engine taint my perception of V8s in general. There’s a reason many more automakers besides the Big Three cleave to or have gravitated toward the configuration.
I’ve always been an inline-six and rotary engine buff. I’ve been fortunate enough to have owned a few Mazda rotaries and a number of inline sixes from a variety of manufacturers (Nissan L24, Toyota 7M and 1JZ, BMW M30 and M50), so my predilection for those configurations’ inherent smoothness and refinement has been cemented for ages. I sneered at the V8’s less-than-optimal internal geometry that meant it could never be as naturally smooth as a fully-counterweighted inline-six. I adopted a kind of snobbish engineering puritanism.
But I’m happy to report that my month-and-a-half of life with my 1995 540i’s 4.0l M60 V8 (shown above) has helped me see the light. It’s a cross-plane design and very nearly as smooth as my old 525’s M50 in the upper rev range. The additional two power-pulses per cycle contribute to the feeling of refinement and give it a lovely noise. And it pulls like a freight train. I may not have completely “come to the dark side” and become an avid fan of the pushrod variation—they’re still too ubiquitous, and I like my cams up top, please—but as of this writing, send me my long-delayed V8 Fan Club membership card.
