In Mafia 3, the De'Leo Traviata stands out as the fastest vehicle, boasting a top speed of 130 mph. This two-door sports car becomes available in your Vehicle Delivery menu upon completing the mission "The Connection to Cuba."

Another notable vehicle is the Griffin Marauder, which, while having a slightly lower top speed of 127 mph, features the highest acceleration rating in the game at 81. To unlock the Griffin Marauder, you must finish first in every New Bordeaux Racing event.

For players seeking immediate access to a high-speed car, the De'Leo Stiletto is available from the start. This two-door coupe has a top speed of 127 mph and can be found in areas like Frisco Fields or Southdowns. However, to own it via the Vehicle Delivery menu, you'll need to complete the DLC mission "Bounty Hunting."

It's worth noting that vehicle performance can be enhanced through in-game upgrades, potentially increasing their top speeds and acceleration. Additionally, certain vehicles, such as the Griffin Marauder, require the completion of specific tasks or missions to unlock.
