A Radical American Supercar

The Dodge Viper first appeared as a concept car at the North American International Auto Show in 1989. Built in sheet metal by Metalcrafters, the dramatic two-seat roadster attracted such an enthusiastic response from the public that Chrysler management instructed chief engineer Roy Sjoberg to develop the concept into a production vehicle.

The V10 Engine

At the heart of the Viper was its enormous V10 engine. Lamborghini, which was then owned by Chrysler Corporation, was involved in developing the engine by converting Chrysler's existing V8 architecture to an aluminium-alloy construction. The result was a lightweight and powerful engine that became one of the defining features of the Viper.

Lightweight Construction

The Viper was built around a tubular steel frame with resin transfer moulding (RTM) fibreglass body panels. Keeping the structure and bodywork relatively light was an important part of the car's design philosophy.

Modern electronic driver aids were deliberately avoided. The early Viper was not equipped with traction control or anti-lock brakes, leaving the driver much more directly connected to the car's performance.

The result was impressive acceleration, with the Viper capable of completing the quarter mile in approximately 12.6 seconds.

Performance Before Comfort

The Viper was deliberately spartan. Performance was given priority over luxury and convenience, creating a driving experience that was very different from many contemporary sports cars.

The car did feature adjustable seats and inflatable lumbar support, but many conventional features were omitted. There were no exterior door handles, while the open-top design meant there were no conventional side windows or permanent roof.

A soft top was available, although it was primarily intended for indoor vehicle storage rather than providing the refinement of a conventional convertible roof.

A Unique Open-Air Design

When protection from the weather was required, fabric and clear plastic side curtains could be fitted into the doors. These were secured using zippers and hand-operated fasteners.

The unusual arrangement was another example of the Viper's uncompromising approach. Rather than adding heavy mechanisms and equipment, Dodge kept the car as simple and lightweight as possible.

Performance Comes First

The original Viper was never intended to be a comfortable grand tourer. Its purpose was to deliver raw performance and an engaging driving experience with as few distractions as possible.

With its enormous V10 engine, lightweight construction, minimal electronic assistance and deliberately basic equipment, the Viper established itself as one of America's most uncompromising performance cars.

The result was a car where performance came first and creature comforts came last, creating an unmistakable character that would define the Viper throughout its production history.
