Assuming that there are no actual faults affecting performance, the two
things that initially spring to mind are either a relatively tight,
low-mileage engine (if applicable?) or a more accurate speedo - or maybe a
combination of the two??

Alternatively, maybe slightly different gearing??

I belive that the new one is 150lbs heavier. More sound deadening,
thicker safety glass, bigger dimensionally. More mass=less speed!

Or a less accurate speedo - I just got a GPS system - I used it in a
Merc and checked the speedo on the motorway - It compared spot on with
the Merc.

In my 2 year Focus 2L Ghia, the speedo reads 34 when the gps tells me
that I am doing 30. The speedo consistently is 'fast' compared with
the GPS.

I tend to believe in the cesium clocks on the GPS than the speedo on
the car. HOWEVER, I use the car speedo if a police car tailing me!!!

Exactly, GPS should be correct concerning speed withing +/- 0.1
km/h. The speedo on my Focus shows about +5% more then GPS, a
pretty good value for some Ford speedometer. In addition it has
the annoying feature that it stops shortly before 220 km/h, while
revs are still going up.

the 

GPS vs. speedo comparison is similar in my experience too - speedo reads
4mph fast at all legal speeds compared to GPS, indicating it is actually a
pretty accurate unit with an in-built over-read that remains consistent. As
an aside, my GPS reads identically to these flashing roadside speed signs
that seem to be proliferating in this neck of the woods.

Just to clarify my earlier comments with regard to the OP, the more accurate
speedo reasoning relates to the newer car - if the one in the old car
over-read a lot and the one in the new car over-reads less, then this could
give the OP the impression that the new car is slower over his chosen
performance test (especially if the new car is also a bit quieter and
smoother to drive than the old one too)

Hi
I don´t know about the law in the USA, but here in Germany a speedo is
only allowed to over-read the real speed by about 10% of the max. speed
indicatable, but not a bit slower then the right speed.
This leads to speedos with a over-read of about 2-10 km/h, bad ones
until 15-20 km/h. About 5 is normaly.

While travelling on a straight road and at constant speed the GPS always
reports a road speed that is 10 percent below that reported by my 2001
UK (Geman) Focus speedometer (over the range 30 to 80 miles per hour)
