The Jester Classic is mostly based on the Toyota Supra JZA80. The car is equipped with an inline engine sporting a performance intake manifold. Unlike the Supra, the Jester is front-wheel-drive, yet retains its sporty qualities. In acceleration, speed, handling, and braking, the Jester is inferior to most other sports cars and tuners in the game, superior only to the Euros. However, the vehicle still possesses good grip and braking, ideal for sharp cornering using the brake or handbrake. Like most tuners in the game, the body construction is poor, making the car susceptible to intense damage from high-speed impacts and heavy gunfire.
The turbocharged variant could achieve 0–60 mph in as low as 4.6 seconds and 1/4-mile (402 m) in 13.1 seconds at 109 mph (175 km/h). The turbo version was tested to reach over 285 km/h (177 mph), but the cars are restricted to just 180 km/h (112 mph) in Japan and 250 km/h (155 mph) elsewhere. European versions of the car also had an air intake or scoop on the hood. Drag coefficient is 0.31 for the naturally aspirated models and 0.32 for the turbo models but unknown with the rear spoiler. The twin turbos operated in sequential mode, not parallel. Initially, all of the exhaust is routed to the first turbine for reduced lag. This resulted in boost and enhanced torque as early as 1800 rpm, where it already produced 300 lb⋅ft (410 N⋅m) of torque. At 3500 rpm, some of the exhaust is routed to the second turbine for a "pre-boost" mode, although none of the compressor output is used by the engine at this point. At 4000 rpm, the second turbo's output is used to augment the first turbo's output. Compared to the parallel mode, sequential mode turbos provide quicker low RPM response and increased high RPM boost. This high RPM boost was also aided with technology originally present in the 7M-GE in the form of the Acoustic Control Induction System (ACIS) which is a way of managing the air compression pulses within the intake piping as to increase power.
