AERODYNAMICS

To improve aerodynamic performance, the following measures have been taken.

A large rain gutter has been provided in the front pillar to ensure a smooth airflow from the

front to the side.

The front edge of the hood and the area around the headlights offers a smooth shape with

minimal level differences for smooth airflow characteristics.

The under shape of the front bumper collects the flow of air under the floor.

The body line from the roof to the luggage compartment allows the air to flow smoothly from

the top of the roof to the rear.

To ensure a smooth airflow from the roof to the rear, the shape of the luggage compartment

door has been optimized.
