Saints Row

When you enter a vehicle, you'll notice in the bottom right of your screen that there is a special task for the vehicle that you can complete to unlock a "signature ability" for the car. Sometimes you'll need to sideswipe enemy vehicles, sometimes you'll need to do damage with a towed item. This achievement is unlocked when you unlock each type of signature ability. You do not need to unlock every vehicle's ability, just one vehicle of each type. You also do not need to activate the upgrade in a garage; fulfilling the unlock requirements is enough for achievement credit. There are eight signature abilities you can unlock and one special task that correlates with each one. To unlock the abilities, you must be driving the correct "type" of car. For example, an Ant has the "Super Air Control" signature ability, so you wouldn't be able to unlock the "Crab Steering" ability in the Ant.

Ball & Chain: This signature ability gives your car a wrecking ball that you can drag behind you. To unlock it, you'll need to smash 100 items with a towed object. You'll need to purchase the towing equipment upgrade from the garage and then find something to tow. The easiest thing to use is another car. Back up against the bumper of another car, press to tow it, and drive around swinging the towed car into things. Once you hit 100 objects or people, you'll unlock the signature ability.

This ability is available on the Dustrider, which is given as a reward for completing Castle Kraken's questlines. It is also available on Shafts (tow trucks) seen around the city or in Wuzyer's repo yard.

Crab Steering: This signature ability allows you to move your car from side to side like a crab. To unlock it, you need to sideswipe 8 enemy vehicles with your car. To get credit, the car you sideswipe has to belong to a police officer, a gang member, or a hostile civilian. You don't have to destroy the vehicle, just sideswipe it at least once. Do this eight times and you'll unlock the signature ability.

This ability is available on Rides, which is the type of car that Eli drives. You should have one in your garage early on in the game.

Kneecappers: This signature ability allows you to send spikes out from your tires to easily destroy a nearby vehicle. To unlock it, you'll need to earn a streak of eight near misses with your car. The best place to do this, in my experience, is a highway such as the long bridge that connects the eastern and western parts of the map. You'll need to drive close to another car and pass it without hitting it. These can be oncoming cars or just cars you speed past in the correct lane. Once you have a streak of eight, you'll unlock the signature ability.

This ability is available on Shiftys (go karts) or Hammerheads (muscle cars around Los Panteros territory).

Infinite Boost: This signature ability allows you to use infinite nitrous while in a vehicle. To unlock it, you need to use the full nitrous boost for a car three times. This means starting with a full nitrous meter, giving yourself boost, and not stopping until the bar is empty. You'll want to do this on a straight flat road to give yourself the best chance. I personally used an ambulance since they're slow and aren't too difficult to control while boosting. Once you deplete the bar three separate times, you'll unlock the signature ability.

This ability is available on Responders (ambulances) or Attraziones. You will receive an Attrazione after completing all of the chop shop missions at Jim Rob's garage.

Ejector Seats: This signature ability gives your car an ejector seat so that you can blast off into the air while driving. To unlock it, you'll need to deploy your wingsuit while driving. To do this, you'll want to find a straight road and build up some speed. Once you're at full speed, hold to get on top of your car and then press the button to deploy your wingsuit. Even if you die immediately from hitting a wall, you'll get credit and unlock the signature ability.

This ability is available on Olives (four-door sedans) which are found commonly near the church or near Marina Del Lago. You may have one in your garage at the start of the game with certain editions/pre-order bonuses.

Air Boost: This signature ability allows you to boost your car upward with nitrous while midair. To unlock it, you'll need to do three separate 360 spins. You'll need to hit a ramp with high speed and hold the left stick to the right or left until your car completes a 360 degree spin. Do this three times to unlock the signature ability. There are a ton of ramps in the graveyard near Jim Rob's garage that you can use.

This ability is available on Shields (Cadillac-style cop cars), which are driven by police.

Jump: This signature ability allows you to jump your car upward into the air while driving. To unlock it, you'll need to do three barrel rolls. You'll need to hit a ramp with high speed, hold and also hold the left stick to the right or left until your car completes a full barrel roll. Do this three times to unlock the signature ability.

This ability is available on Ridgelord (pick up trucks). You have one of these in your garage at the beginning of the game.

Super Air Control: This signature ability gives you greater control of the vehicle while midair. To unlock it, you'll need to do two back flips. As of writing this guide (8/27/22) you do not have to do a "double" back flip like the game says - you just have to do two black flips. These can be two separate jumps. You'll need to hit a ramp with high speed and hold the left stick down until your car flips backward. Do this twice to unlock the signature ability.

This ability is available on Ants (dune buggy that looks like an old-style racing Beetle), which are found in the desert/badlands. You may have one in your garage at the start of the game with certain editions/pre-order bonuses.

Note: There are some special vehicles in the game that have a unique signature ability, such as the Bowelrod car, but these don't seem to count toward achievement progress.
