The Turismo in Grand Theft Auto IV is based heavily on the Ferrari 360, and to a lesser extent, the Ferrari F430. The front fascia also heavily resembles the McLaren 12C, although the resemblance is coincidental. The rear fascia however, consists of a sleek taillight-radiator cluster, with four-sided taillights, as opposed to the 360's circular lights. The rims, which resemble three-piece OZ Racing Superleggera rims, are installed over cross-drilled brake rotors. The Turismo also lacks an external rod antenna.
The Turismo's interior features two bucket sport seats and full leather appointments finished in classic tan. The car also features a fully-carpeted boot in front of the cabin with ample space for luggage, which is revealed after significantly damaging the front of the car.
The Turismo will appear either with flat slatted grilles or with scooped intakes, both located on the rear fenders. On the Auto Eroticar website a unique Turismo with a spoiler is shown.
Handling of the car is arguably the best of all cars in IV, due to the Turismo's good brakes and near-perfect weight distribution. The car is almost never susceptible to burnouts during cornering due to excess torque, owing to its weight distribution and rear-wheel drive drivetrain. Thanks to its mid engine layout, the car can turn corners sharply. It is one of the easiest supercars to drive in the game. The mid engine layout also means that it is shielded from frontal impacts and mildly shielded from rear impacts making it a very durable car. Overall, due to its durability, speed and handling, it is well suited for all purposes. Just keep in mind that it does not do a good job of absorbing bullets, but shielded in the front and rear.
According to Autoeroticar.com, the Turismo's engine in GTA IV is a high-revving 4.0L Quad Cam V8 fitted to 5-speed manual transmission. Its engine model is roughly similar to that of the Infernus of the same game, with "GROTTI" printed on the cam covers. True to the website statement, it is coupled to a 5-speed manual gearbox in a rear engine, rear wheel drive layout. The website also specifies that the vehicle features ABS, which is somewhat complemented with the fact that the wheels rarely locks under braking pressure (only locks if the car encounters a significant bump on the road), as well as having good turning while braking it.
According to the game files, its speed is about the same as most sports cars in the game, such as the Comet or the Banshee.
