The Grinder's 2.5 liter V6 is rather small, and only makes 124 horsepower in stock form. Acceleration is quite slow, even with upgrades applied, and the car's long wheelbase and soft suspension make cornering somewhat difficult compared to the other, much smaller cars in the same class. However, the Blocker's true performance shines when it is given a straight-line space to accelerate into, clocking out a top speed of 135 MPH, a speed that's comparable to higher-end Silver Class and even some Gold Class cars. However, ambitious players should note that reaching this top speed is relatively difficult without vast amounts of nitrous to use for acceleration. The Grinder is a relatively good racer, given its higher top speed and friendly handling, however, players should take note of the car's slow brakes and difficult turning compared to other vehicles in the class.
In demolition derbies, the Grinder is a decent performer, with good structural integrity and decent hitting ability. Drivers will do best if they avoid heavy fights in the demolition ring, and instead focus on attacking lighter, more defenseless cars that have stopped or slowed. Using the sloped sides of the ring as quick turning points is also very desirable, as is judicious use of the handbrake.
- The car's styling is very similar to that of the compact 1960's Plymouth Valiant/Duster muscle car, though with a much smaller engine. The hood also appears to be a nod to the Dodge Challenger, another Chrysler product.
- Making 205 horsepower when fully upgraded, the Grinder's power to weight ratio sits at 149 horsepower per ton, the second lowest in its class.
- The car's name was reused in the series later on for FlatOut: Ultimate Carnage, with its design being updated to resemble a 1980's Chevrolet Camaro. For information on this car, see Grinder.
