top luxury trim similar to the Caprice and Malibu Classic) sent Nova into the luxury portion of the compact market; some actually thought of it as competing against a few high-end European imports. The Nova LN was called "the most luxurious compact in Chevrolet's history," with wide-back reclining front seats that "look and feel like big, soft lounge chairs." LN equipment included ad­ditional sound insulation, map pockets, an electric clock, a smoked instrument lens, floor shifter and center console, and a day/night mirror. Taillight lenses have additional white accents unavailable with the base model and a chrome plated grille. Above the front marker lenses, the LN had 4.3 LITER (or 5.7 LITER) decals - making it the first Chevrolet product with metric displacement badges sold in the Americas. Swing-out quarter windows could be ordered for the coupe. "Thanks to LN," the sales brochure announced, "Nova's image will never be the same again." The LN was more Eurocentric as opposed to the Custom which became the mid-level trim option. For 1976 the Nova LN was rebranded Concours to rival the Ford Granada and the Mercury Monarch, as well as upscale versions of the Dodge Dart and Plymouth Valiant. Like regular versions of the 1976 Nova, the Concours came in three body styles: coupe, hatchback coupe, and four-door sedan. Concours was the most luxurious Chevrolet compact to date. Rosewood vinyl decorated the upper door panels, instrument panel, and steering wheel. Concours models had an upright hood ornament, bumper guards, bright trim moldings, black bumper impact strips, and full wheel covers; more-basic Novas came with hubcaps. The Concours coupe also was the first Chevrolet coupe with a fold-down front center armrest. A V-8 Concours coupe sold for $547 more than the comparable base Nova. Engines for the 1976 Chevrolet Nova were a 105-horsepower inline-six, a 165-horsepower 350-cubic-inch V-8, or a 140-horse 305-cubic-inch V-8. 1976 GM vehicles first saw use of the THM200 — from the GM T platform to GM X-Bodies (Chevrolet Nova et al.). A lighter duty 10 bolt rear differential with a 7.5" ring gear (also used with the Vega/Monza) was phased into production (last produced in 2005) - which was standard equipment with the base inline six. A Cabriolet padded vinyl top was available for Nova coupes. Modest revisions were made to the brakes, and also to fuel and exhaust system mountings. Dashboards contained new knobs.
