Correct me if I am wrong but as far as I know this will be it:

New grill (like the coupé)
Newly shaped front bumper
The engine cover would have a slighthly new shape
The taillights will be different concerning shape and colour.
Headlights don't really look changed
Interior upgrades (but I can't really remember having seen interior pics nor specs)
Some new wheels (see the small pic on page 49)

Please feel free to complete or correct when required!
