I have a red car
As far as I know, there has only been one US OHC inline six cylinder engine available as regular production in the last 60+ years
Yeah, and that's the GM 4.2L I6 Vortec all aluminum engine. Unfortunately it only enjoyed a short production run because it was too long and tall to be packaged into later GM models that required transversely mounted engines. AMC/Jeep did use an OHV straight six from 1964-2006 in various guises, with the venerable 4.0L in production from 1987-2006.
The straight six fell out of favor purely because it's easier to fit a V6 transversely under the hood to save space and lower the hood line. Otherwise the I6 is a far smoother engine than the V6, and BMW still use it to this day. In fact the same BMW turbocharged 3.0L I6 that's fitted to the BMW Z4 also appears in the new Toyota Supra.
So there you have it. Toyota has a new I6 that is actually German and is an awesome piece of work. Both BMW and Toyota have lied about their claimed HP/TQ numbers as chassis dyno tests have shown that the same engine in both vehicles produces more HP/TQ at the rear wheels than the manufacturers are claiming it produces at the crank!
The Ford 2.3L I4 Ecoboost tries hard but it couldn't hold a candle to the BMW I6 engine either. I can see the latter engine being swapped into many other vehicles in the future as Supras end up in wrecking yards, so don't be surprised if that engine also finds its way under the hood of a Mustang a la Fast & Furious 3 Tokyo Drift.
