It's gotta be better than the Focus RS.
When it comes to fantasizing about possible production cars, it doesn't get much farther from reality than this. Though this render of a "Ford Taurus RS" looks pretty mean, it is based on the all-new, China-only Taurus. As such, it is not designated for the US market, nor is it likely to spawn a performance-oriented RS version anytime in the near future. That being said, what engine/drivetrain arsenal would you replace the production 2.7-liter EcoBoost V6 with to make a true RS-worthy killer sedan?
