A while ago I looked for stuff online about it because there were no posts in this forum, but I don't think I could find anything.

In 1958, after 11 years of small-scale car production, the first true series production TVR was built. Initially known just as the Mk1, it was based on an earlier coupe design but with a fastback shape to provide more interior space. The multi-tubular chassis had independent suspension at both ends originating from the front of a VW Beetle. Very stiff springs were needed to reduce the potentially high roll angles, giving the car a hard ride. A variety of engine options was offered, including Coventry Climax, Ford with or without Shorrock supercharger or the unit from the MGA. Various detail changes were made as the car was constantly developed. By 1960, when the Mk2 was launched, the car was called Grantura. Raised rear wings incorporating new tail lights and flared wheel arches were the main visual differences. 1961 saw the introduction of the Mk2A, the first TVR to be road-tested by a national magazine. Disc brakes from the Triumph TR3 replaced the front drums. 1962 saw the introduction of the Mk3, with a completely new chassis design incorporating a 1.5" longer wheelbase, coil springs and wishbone suspension all round. Externally the bodywork was similar but with a revised nose to improve cooling. Ride and handling were both greatly improved over previous models.

In 1964 the Mk3 1800S was introduced which used the MGB engine and had a revised 'Manx' tail incorporating the 'ban the bomb' rear lights from the Ford Cortina Mk1. By 1966 when the Mk4 1800S appeared the Martin Lilley era had begun. Many improvements had been made to the interior and heating/ventilation systems to make the car more comfortable. Weight was up as a result, but with 98bhp from the MGB engine, performance was still good. In 1967 the last Grantura was made, and the Vixen displaced it.

The TVR Grantura Mark I was revealed in 1958 and was put on display in the showroom of one of Manchesters Ford-dealers. This car was the only assembled, complete TVR, even if Trevor Wilkinson said that -"... it's one in a batch of ten cars". The car was stubby and characteristic, a long bonnet and a short contoured tail. This was to be the basic design of all TVRs until 1980.

The car was built with a multi-tubular frame and a glassfibre body. The enginebay was large and a wide variety of different engines was used in these early TVRs. A VW-based trailing-link independent suspension was fitted to both front and rear. This was so stiff that no anti-roll bars were needed.

When the Grantura Mark II was introduced late 1960, it was effectively a lightly modified Mark I with several improvements and a little visual retouching. The main engine was now the MGA 1588cc producing 80 bhp. The Mark II sold a lot better than the Mark I, but was only produced for a couple of months.

The Grantura Mark IIA that followed in early 1961 was basically a Mark II with Girling front discbrakes, a modified engine line-up and a quarter-windowthat no longer could be opened. This was the first TVR that (independently tested by Autocar) exceeded 100 mph.

A new chassis was needed to rectify some of the shortcomings of the original design. The trailing arms was replaced both in the front and rear with a double-wishbone layout allied to coil-springs. The design included a longer wheelbase which gave the cars a bit more leg-room but the originally narrow door was retained. The model that first used this new chassis was named Grantura Mark III.

TVR redesigned the body for the 1964 NewYork Auto Show. The reshaped "Manx-tail" was easy to see and the rear-window was made larger and sleeker. This model is known as the Grantura 1800S. It still used the 1798cc MGB engine as found in the late Mark II's.

The Grantura Mark IV was quite simply a refined and improved version of the 1800S. Martin Lilley who owned the company at this time was focusing on quality and the overall quality was better on this car. A lot of small changes were made. The car got wooden panels on the dashboard, the spring-and-damper was revised to provide a smoother ride and the engine was moved forward slightly.
