in the wild Inline 6 (I6) engines have proved reliable and just going on regular maintenance

B58 (BMW) is super reliable & high performance

same as the I6 used in certain landcruisers & other Toyota cars etc

though now of course - with super cheap solar etc - if you can go electric go electric but if you've to buy an ICE car - yeah buy an I6 - fuel efficient & performance & reliable

This is an extremely popular layout in heavy duty applications.

In europe inline-fours are more popular. Cheaper and less fuel.

Well for Stellantis their fans rather want the Hemi V8 back, but they are offering a turbo charged inline 6 (Hurricane).

Badging a Mercedes as an AMG and asking the price for it and you just fit turbos on a 4 cylinder.

Great news!
