I did drive the new Ford Taurus and thought it was worlds better then the Taurus's or 500s of the past. However, there was still significant wind noise, it gets about 21 mph and not as strong accelerating as advertised. The suspension made some noise going over bumps.
In comparison, any model camry or accord in the last 10 years is quieter, smoother riding and gets better gas mileage.
I would rather drive a 2003 Camry or Accord then a 2008 Ford Taurus.
Ford has improved greatly, but still lags far behind their Asian counterparts.
Ford Taurus=20 MPG average, not long lasting, lots of defects, still a rough ride, noisy
Camry or Accord= 26-28 MPG average, 15 year car, no defects, quite, smooth comfortable ride
