The Istante is a sports car made by Assoluto, available only in Rage Racer. It's first available as a Grade 4 car, powered by a 3.5 liter double overhead cam flat-12 engine, putting out 380 ps and enabling the car to reach a top speed of 296 km/h. An optional Grade 5 upgrade gives the car a new 4.2 liter engine, increasing the car's power and top speed to 450 ps and 310 km/h. Power is transmitted through a 6 speed gearbox.
- The car is said to resemble both the Vector W8 (on the front end and its angular styling) with bits of the Lamborghini Countach LP5000 QV on the rear.
- However the Istante makes more references to the Lamborghini Countach LP5000 QV as the car is powered by a twelve-cylinder engine (as opposed to the Vector W8's twin-turbo V8), has a similar rear wing, makes roughly similar power and the fact that it is a manual-only car (the Vector W8 has a three-speed automatic).
