text: Panoramic roof systems are a type of large or multi-panel moonroof which offer openings above both the front and rear seats and may be operable or fixed glass panels. An early example visually very similar to many current versions was paraded around the Monaco Grand Prix circuit in 1969, it comprised a full-length fixed Plexiglas panel and was fitted to a Lamborghini Espada. The first example of a panoramic roof however was incorporated into the 1953 Lincoln XL-500 concept car which sported a full-length Plexiglas bubble canopy. Large operable openings are often accomplished with top-slider (tracks in the top of the roof) or spoiler type mechanisms. Examples include the Acura ZDX, Lexus ES, BMW Mini, Scion tC, Pontiac G6, Mercedes C Class, Volkswagen Eos, Porsche Cayenne, and the Tesla Model S.
  Removable roof panels (t-tops or targa roofs) open a vehicle roof to the side windows, providing a wider opening than other roof systems. The Targa body style is identical in configuration to the Sedanca but is designed for owner-driven rather than chauffeured cars and while a Sedanca style implies a rear passenger area, the Targa does not. T-roofs have two removable panels and leave a T-shaped structural brace in the roof center. Targa roofs include only one (opaque or transparent) panel and leave no cross brace. Aftermarket kits are no longer made, but several companies sell replacement and remanufactured panels, parts and accessories. Examples include Triumph TR4, Porsche 911 Targa, Suzuki Cappuccino, Toyota Supra, Pontiac Firebird, Chevrolet Corvette, Honda NSX, and Porsche 914.
