DesignThis car has a highly debatable design, however it takes many design cues from a Pontiac G6 (main styling/shape, and the bottom of the front clip), a 1999-2005 Pontiac Grand Am (the greenhouse/roof), a Saturn Ion (the shape of the back doors); although the headlights look close to the ones on an Ion, judging by the narrowness, they are closer to a 2006-2011 Honda Civic; the taillights look somewhat like that of a 2000-2005 Pontiac Bonneville (the reverse lights integrated on the strip with "IMPONTE" on it seems similar to the ones on 1995-1999 Chevrolet Luminas, the actual strip itself is closer to the Bonneville). The black-tinted roof and rear lights that run the length of the car are inspired from the Subaru SVX. The dashboard features red lighting, a Pontiac trademark.
Despite its near similar design, the DF8-90 is available in three different variants, each identifiable by the presence of a spoiler or the type of spoilers used, and their badges on the trunk lid. The base variant, which has no apparent indication of what engine it has, has no spoiler; the 3.8 liter Supercharged V6 Sport variant, however, features a basic spoiler, while the top-of-the-line 5.3 liter Supercharged V8 Turbo (Imponte Racing) variant features a larger curved spoiler. Otherwise, all three variants share the exact same body and range of body colors, and handling.
Acceleration is respectable, with 0-60 mph managable in 6.5 seconds, and is among the best in its class (RWD 4-door sedans). The high-output engine, coupled to a 5 speed gearbox with a smooth powerband gives the DF8-90 a high top speed of 192 mph (309 km/h). The powerful engines on all models make this car easy to slide/oversteer, and as a result can drift and powerslide very easily while being controllable.
Handling wise, although it sacrifices ride, it makes up for it by being very good with avoidance maneuvers and scores above average, not far in top speed to far more expensive vehicles. Accident deformation is good, considering it's rather sporty nature, but it isn't the best. The cabin holds up well and the same goes for the roof. The DF8-90 can sustain multiple frontal impacts before becoming un-drivable or catching fire.
A DF8-90 is requested as part of Stevie's Car Thefts, featuring a uniquely light blue body color, but may appear in the form of any of the car's three variants. As a new DF8-90 will re-spawn at the same spot until the player delivers one to S&M Auto Sales, the player can save one at their safe-house before delivering another.
- In GTA IV, the V8 Turbo DF8-90 shares its trunk spoiler with the Primo V8 Supercharged..
- This is one of the best vehicles to use when attempting the Swing Glitch.
- The two default radio stations in the DF8-90 are IF99 - International Funk and K109 The Studio.
- A glitch may sometimes allow for the blue DF8-90 required for Stevie's Car Thefts to continue spawning under Hove Beach even after all deliveries are complete. This one, however, will not retain its paint job after being resprayed.
- The DF8-90 shares its interior with the Bravado Feroci.
The DF8-90 can be spotted rarely in traffic, but has been known to spawn in:
- South Slopes, Firefly Projects, Firefly Island, Hove Beach, Beachgate, Beechwood City, Broker
- Westdyke, Alderney
- Alderney City, Alderney
- Lower Easton, The Triangle, Chinatown, Algonquin
- A parked DF8-90 without black-tinted roof can be found in a parking lot under the train tracks in the Hove Beach area in Broker as part of a stolen car delivery mission for Stevie. It sells for approximately $5,500 at Stevie's garage in Bohan.
- The DF8-90 also spawns in the driveway of Mikhail Faustin's mansion in front of the Turismo after you start a mission from him.
