There are two listings, the European version, and the North American version for the models. There are also some differences for Canada.
Since I am here in the USA, here's the basic stuff, I won't go into the packages or too many details. I'm also not going to break it out for the 4-door vs. 5-door which have some MINOR differences(5-door has the rear spoiler standard).
S(only available in 4-door sedan):
2.0L DI engine delivering 160 horsepower(159 for PZEV)
5-speed manual transmission
Front wheel disc brakes, rear drum with Anti-lock braking System
15 inch steel wheels with silver painted covers
Blind spot mirrors
rear bench seat with tip-fold-flat feature
AM/FM Radio with single CD and 4 speakers
Tilt and telescoping steering wheel
Manual air conditioning
Power front windows with driver one-touch down.
SE has all the features of S plus:
16 inch steel wheels with silver painted covers
fog lamps with chrome surrounds
MyKey owner controls
Front and rear floor mats
Steering wheel with secondary audio controls
power front and rear windows with driver one-touch down
SEL has all the features of SE plus:
PowerShift 6-speed automatic with SelectShift manual control
4-wheel disc brakes
16 inch aluminum wheels
Body-color exterior mirrors with integrated turn signal indicators
6 speaker audio system
MyFord driver connect technology
SYNC voice-activated communications and entertainment system
Interior Ambient Lighting
Leather-wrapped steering wheel with cruise and secondary audio controls
dual-zone electronic automatic temperature control
60/40 split rear seats with tip-fold-flat feature
Power front and rear windows with one-touch up/down on all windows
Universal garage door opener
Titanium includes all features in the SEL plus:
17 inch sport aluminum wheels
Rear spoiler(on sedan, hatch has them standard)
Black fog lamp surrounds with chrome accents
Intelligent access with push-button start
MyFord Touch with 8 inch center stack touch screen
SIRIUS Satellite Radio
Sony Audio System with 10 speakers and subwoofer
HD Radio with iTunes Tagging
Note that the S only has the normal 6-speed automatic as an option, and there are NO other options for the most part.
The SE has the Convenience Package(Cruise Control, map lights, Perimeter alarm).
SE MyFord & SYNC package has SYNC elements with USB port, MyFord driver connect package(voice activated stuff), rear 12V powerpoint(lighter jack for car chargers and such), and the 6 speaker audio system.
On the SE, if you get 203A, that is both convenience package and MyFord & SYNC package...it adds SIRIUS as a bonus feature.
SE does have automatic as an option, moonroof, Winter Package(heated front seats and external mirrors plus all-weather floor mats). There are others as well, but the sport pack has some questions about the sport-tuned suspension and if it is included or not these days.
The SEL has MyFord Touch and Sony package(included in the base Titanium)
SEL Premium package(Rain sensing wipers, leather trimmed seats with power drivers seat, 17 inch aluminum wheels, reverse sensing system, auto-dimming rearview mirror, and rear armrest)
The SEL also has the winter package, plus voice activated navigation(requires MyFord Touch I believe), and the parking technology package(automatic parallel parking system).
The Titanium has the premium package as well(same as the SEL version but without the 17 inch wheels since they are standard on the Titanium), and adds a Titanium handling package which has 18 inch wheels with summer tires.
I hope this answers your questions. There are additional accessories such as the cargo net, all weather floor mats, and stuff like that available as well.
