Viper has never been titled still has original certificate of origin! Only 285 made in 1992. Original window sticker still on windshield. Has been stored in heated garages and has only 210 miles. The first prototype was tested in January 1989. It debuted in 1991 with two pre-production models as the pace car for the Indianapolis 500 when Dodge was forced to substitute it in place of the Japanese-built Dodge Stealth because of complaints from the United Auto Workers, and went on sale in January 1992 as the RT/10 Roadster. The centerpiece of the car was its engine. Lamborghini, then owned by Chrysler Corporation, designed the V10 for the Viper by recasting the block and heads in an aluminum alloy, and was based on the Chrysler LA V8 engine. A major contributor to the Viper since the beginning was Dick Winkles, the chief power engineer, who had spent time in Italy. The engine weighs 711 lb (323 kg) and produces 400 bhp (300 kW) at 4600 rpm and 465 lb·ft (630 N·m) at 3600 rpm, and thanks to the long-gearing allowed by the engine, provides fuel economy at a United States Environmental Protection Agency-rated 12 mpg‑US (20 L/100 km; 14 mpg‑imp) city and 20 mpg‑US (12 L/100 km; 24 mpg‑imp) highway. The body is a tubular steel frame with resin transfer molding (RTM) fiberglass panels. It has a curb weight of 3,284 lb (1,490 kg) and lacks modern driver aids such as traction control and anti-lock brakes. It completes a quarter mile (402 m) in 12.6 seconds and has a maximum speed of over 150 mph (240 km/h). Its large tires allow the car to average close to one lateral g in corners, placing it among the elite cars of its day. However, the car proves tricky to drive at high speeds, particularly for the unskilled. The car is spartan, although it features inflatable lumbar support and adjustable seats. Along with the absence of exterior door handles, the vehicle lacks side windows and a roof. Although a soft top cover was available, it was designed primarily for indoor vehicle storage. Side curtains of fabric and clear plastic operated by zippers can be inserted into the door and hand-bolted when needed. All of these decisions were made to reduce weight. The battery is located in the sealed compartment over the rear wheels to increase rear-end weight and traction. The car shipped with a tonneau cover and video tape on soft-top assembly (the soft top is removable and folds to fit in the trunk).
