I gave up on trying to correct the addled brains on this site long ago, but this thread hits new lows — and that is saying something, for LLN. Mention a Taurus or a Mustang in the same sentence, paragraph or even article as a BMW 5-series? Absolute IDIOCY. Moronic. Ignorance on an epic scale. No car minted on US soil will ever have the driving dynamics of a true European car, because Americans, as a whole, are not drivers. Americans drive cars, but they do not have a fine-grained sense of the experience, nor do they get even a tenth the driver education that other countries do. US engineers cut corners and shave at every opportunity, they build to use less steel, they design to mass-produce as cheaply as possible. The seat alone in a 5-series has more thought, engineering and detail in it than a tin box like the Taurus. As for the EcoBoost, it is real easy to brag about an engine that doesn’t exist yet, and that manages to accomplish nothing particularly interesting or novel — a twin turbo that makes barely 98hp per liter? That’s ****ing SHAMEFUL. There are a TON of motors from Subaru, Porsche, BMW, Audi, VW, Mitsubishi, etc. that have been making 120-140hp/liter for decades. Factory stock, with a 360cfm turbo and only 12lbs of boost (.87 BAR) my Subaru EJ20 motor made 118hp/liter and 100lbs torque per liter, in 2002, with a six-year-old boxer engine design. Now it makes over 150hp/liter with the same displacement and the same turbo, just methanol injection and a tune! NOTHING in the EcoHype motor is worth bragging about. Sticking it in a Taurus does not absolve the Taurus of being another unimaginative, primitively engineered US brick.

Back to our inline six: the inline six turbo from the BMW M3 series has been taken successfully to EIGHT HUNDRED HORSEPOWER with the STOCK BLOCK, valves and cams. Yes, 800. Check YouTube, there are plenty of videos. That inline six is a nearly unstoppable motor. EIGHT HUNDRED HORSEPOWER ON PISSWATER 91 OCTANE.

So, this inline six will do just fine, in one of the cars with the best handling dynamics and control of almost any car on the road within 30k of its price range.
