It is now based on the GTA V Sentinel but features a carbon fiber fixed roof in place of the folding hard top and has different wheels. The Sentinel XS does have impressively faster acceleration than its normal counterpart with a higher top speed as well. Being a street racer style car, it is often seen speeding around the streets of Los Santos. Due to this, it is often hard to obtain unless you have a car that is good enough to catch it. The Sentinel XS mainly comes in 2 colors: Silver/Gray or Black.
