Included are black air intakes inside the bumper, optimized cooling airflow, sports chassis (body has been lowered by 15 mm) and elaborate under - floor panels and some special tires with
very low rolling resistance.
Research shows that fitting tires with
very low rolling resistance, combined with the right road surfacing, can provide just as much noise reduction as traditional noise barriers.
