Overall performance levels are significantly higher than those of the 488 GTB, thanks to the increase in power, weight reduction and improved aerodynamic coefficient. That performance is also now accessible to a larger number of drivers thanks to vehicle dynamics systems that make driving on the limit an easier and more confidence-inspiring experience.
It allows its owner to experience a significant improvement in their ability to hold the car when it's closer to its performance limits thanks to the increase in power, weight reduction and improved aerodynamic coefficient.
Kwak and Heft averaged the [C.sub.D] values after reaching a stable range to obtain the exact aerodynamic coefficient [6, 15].
Halo said that Ogin's IEC-Certified wind turbine achieved the best aerodynamic coefficient of performance in the industry.
The "Evo II" featured the AMG PowerPack as "standard" but also came with a radical body kit that featured a massive adjustable rear wing, rear window spoiler, and 17-inch wheels, with the aerodynamic coefficient reduced to 0.29.
The aerodynamic coefficient curves of subconductor 2 varying with the wind attack angles under different bundle spaces are shown in Figure 10.
Aerodynamic coefficient in the velocity coordinate system is as follows:
[C.sub.a] = aerodynamic coefficient, can be derived from ship data the model of which was tested in an aerodynamic tube;
Rotary derivative [C.sub.mq] is the angular velocity derivative, which indicates the change of aerodynamic coefficient due to the increment of pitching angular velocity.
LES is not feasible for higher Reynolds number flow which is the case in this work and DES provides an accurate prediction of the dynamic change in the aerodynamic coefficient. Therefore, DES was used to investigate the influence of the barrier shelter on the vehicle aerody namics in gust wind.
