You have to be kidding!  The main flaw with this "comparison" is that the MKS is an AWD vehicle where the others, as tested , are not!!!  If you want a true comparison, test against the Mercedes E550 4matic and the Audi RS6 and even an AWD Caddy, and then see who is last. Even the RWD BMW should have been out gunned by a lesser powered AWD on this road.  Ive driven this pass hundreds of times over the past 30 years.,  Given the tight and frequent corners, a RWD car will spend lots of time waiting for traction!  The twin turbos are also an advantage at elevation, especially extreme elevation, as has already been pointed out numerous times.  What a shame these publications decided to be so biased!  Full disclosure should be required!!!  Sorry, just another toothy looking Lincoln.

LETHURIN: Yes, the EcoBoost would perform even better at sea level, but the increase in the performance of the naturally aspirated engines would be much greater. Dont act like you know it all and then reveal the depths of your ignorance.

Don't get me wrong, the MKS is a fantastic car with a fantastic motor, I just don't approve of the comparison they did.

So what if those are the performance stats for all the cars at sea level?  The point everyone is trying to make is that the MKS can get much closer to matching its "sea level" performance at 12,000 ft. than all the other cars can.  And maybe I'm young because I've never been called a parrot before.  And I really am a junior in mechanical engineering at Virginia Tech, sean.

Okay. Let's look at the facts at SEA LEVEL for all you gear head whiners!
60mph/ 1/4mi:
Lincoln MKS 5.2 sec/13.7 sec
BMW 550i 5.2/13.7
Jaguar XF 5.5/14.0
Maserati Quattroporte 5.3/13.9
Mercedes Benz E550 4.8/13.4
it will be interesting to see how that looks to you guys. But the MKS is pretty mid pack at sea level, too.
Also:
MKS has lowest power / weight ratio, compensated for by broad, linear torque curve
MKS has highest EPA highway fuel economy rating @ 25 mpg (vs. average of competitors @ 22 mpg, with Maserati @ 17 mpg = gas guzzler tax)
MKS has only full five star front & side NHTSA crash test rating
MKS is tied with Maserati with largest interior volume
MKS is tied with Jaguar with largest trunk volume
MKS is $10K - $72K less expensive
