Six pistons in a line—a wonderfully simple design that produced a well balanced, reliable and vibration free engine.

Although increased power requirements combined with constantly decreasing engine space have made the inline six cylinder engine a rare breed, we certainly haven't forgotten the I6.

I would be doing a great disservice to the Chrysler products I love if I didn't pick the 225ci Slant Six. Earning it's slant nickname because it was installed at a 30 degree angle, it didn't take long for Mopar's engine to earn a reputation for bulletproof reliability. The engine first appeared in some of my favorite "Forward Look" Mopars as the "30-D Economy Six" engine in 1960 and a version of the same engine lasted well into the 80s. They weren't the quickest engines, especially in a big car, but they were nearly bulletproof. Except of course for the one example I owned.
