termed the instrument panel in the automotive industry. Sometimes this term is confused with the instrument cluster, the group of speedometer, odometer and similar devices generally behind the steering wheel. K Kammback A car body style that calls for a body with smooth contours that continues to a tail that is abruptly cut. L Leafscreen Plastic clips onto the base of the windscreen under the bonnet to protect from leaves and flowers. Leafscreen retainer Bonded to the base of the windscreen to provide a mounting surface for the leafscreen N NACA duct A distinctively shaped inlet that is flush and begins with a narrow, shallow inset and becomes progressively wider and deeper. The duct was developed to introduce cooling air into aircraft engine nacelles, while increasing the drag of the nacelle only minimally. The duct was developed at the National Advisory Committee for Aeronautics (NACA). O Overhang The distance the car's body extends beyond the wheelbase at the front (front overhang) and rear (rear overhang). In car style design terms, this is the amount of body that is beyond the wheels or wheel arches. In general, the sum of the front and rear overhangs is equal to the overall length minus the wheelbase. Typically, the rear overhang is larger on rear-wheel drive cars, while the front overhang is larger on front-wheel drive cars. Journalist Paul Niedermeyer has proposed an overhang ratio, computed as . Obscuration band Black graphite printed onto the glass to hide unsightly areas and improve aesthetics. P Phaeton An open vehicle, usually with 4 doors, with a removable and/or retractable cloth top and a windshield characterized by the lack of integrated glass side windows. Contemporary uses of this name do not always follow this original description or apply to an open vehicle. Pillar A structural member that connects the roof to the body of the car. Pillars are usually notated from front to back alphabetically (e.g. the A-pillar joins the windshield to the frontmost side windows, the B-pillar is next to the front occupants' heads, etc.). The angle of the A-pillar and the are related. An imaginary line extending from the base of the A-pillar and following its angle will pass in front of the front axle for most front-wheel drive and mid-engined cars, while it will pass through or behind the front axle for most rear-wheel drive cars. Pulling the A-pillar forward increases cabin volume, but
