I don't know about those other three packs but the limited edition stuff from what I've read is just a early unlock of two existing cars albeit with a added unique color scheme.
(For multiplayer.)

BUT THE 3 POWER PACKS = YOU DONT GET 3 MORE CARS

Power Pack (FOR EXAMPLE A SPECIAL STREET ENGINE)

Speed Pack (STREET TYRES)

Strike Pack (Optimized Aerodynamic Body)

SEE THAT

• 2 Limited Edition Vehicles – Get early access in online multiplayer to two of the World’s hottest cars complete with the exclusive Satin Black livery and the latest performance modifications.

• The ultimate in speed and style, there isn’t a more impressive piece of automotive engineering than the Maserati GranTurismo MC Stradale featuring these Limited Edition modifications:

o Racing Engine and brakes tuned for increased power and control.

o The Ground Effect Body increases down-force for better maneuverability.

• The powerful, lightweight and super responsive 2012 Porsche 911 Carrera S is perfect for ditching rivals at breakneck speed and comes equipped with these Limited Edition modifications:

o Optimized Aerodynamic Body reducing drag for maximum top speed.

o Efficient and sustained speed boost with the Nitrous Burn.
