TVR TUSCAN CONVERTIBLE - TECHNICAL SPECIFICATIONS

Body and Interior

The Tuscan is a two seat, two door convertible, manufactured in glass reinforced polyester resin with Kevlar and carbon fibre inserts for additional strength. This is moulderd in one section for the forward opening bonnet and one section for the remainder of the bodyshell. Strategically designed internal body crumple zones protect front and rear portions of the vehicle, complying to all current safety legislation.

A laminated front windscreen and frameless door windows combine with twin roof panels and a fold down header to complete the roof structure. This allows the vehicle to be driven in a number of open and closed positions. The roof is trimmed in mohair in a variety of colour schemes.

The modular dashboard houses full instrumentation of speedometer, electric tachometer, oil pressure, fuel, water temperature gauges, along with voltmeter and electric clock. Windows are electrically operated as are twin exterior door mirrors.
