Note the way various panels can be exchanged to test different airflows. Keith was a founding member of the “Saturday Club” that created the Concept that was launch at the NEC in October 1988. It was conceived as a Group B racer and that Group required a minimum of 200 road-legal cars to be available to the public. The design therefore needed to be aerodynamically competitive on the track and stable on the road.

This model was created as part of a test and development programme at the MIRA wind tunnel and rolling road to achieve both objectives. The aerodynamic results for the front-end and diffuser were adopted for both the concept and the production car, making the XJ220 the first “ground effect” production car. It is this aspect that makes this model unique as the only working research and development Jaguar model designed to achieve this.

The story of the design evolution of the concept into the final production version is well-told in Keith’s own book “Desire & Design,” a copy of which is included. A key element of the story was the wind tunnel testing of this model in the MIRA facility in the Midlands. Originally, the model had no wheels as these came with the wind tunnel set up. The model is now fitted with a set of display wheels on spacers, which set the model up to the equivalent road-legal ride height and track. Three photos also accompany this Lot, showing the model at MIRA before and during the wind tunnel testing.

This is a seriously historic piece that played a central role in shaping the XJ220 bodywork, which is to my eye, the most beautiful car Jaguar produced – a highly-competitive field! Fine. Unique. Historic.

This set of seven show the bodywork being formed over the wooden “egg-crate buck along with the power chain. One photo signed by Keith Helfet, the designer. NB. These photos and all the XJ220 photos that follow are high-definition digital prints mounted on foamboard measuring 12 x 8, unless otherwise indicated. Fine.

One is signed by Keith and another shows Nick Hull, lead designer for the interior of the concept and the production car. Fine.

Fine.

At this stage the team were still hoping that Jaguar’s marketing team would come to their senses and call the car XK220 29 x 12 after the 1950s sports cars – but it was not to be. The rest of the world could see this was not a saloon, but not the marketeers, who were firm on XJ220. Fine.

The 1:18 scale model is mounted on a wooden base with the whole encased in an oaken box. The model and the box are signed by Keith Helfet, designer of the car. Mint.

Compulsion Gallery Ltd was a Kent-based company, now closed, that produced hand-cast sculptures in a special high density resin material that were then thermal-plated with lead-free pewter. Each piece was hand polished and lacquered to preserve the superb metal finish. These models have the look, weight and cold feel of solid metal. This model has Keith’s signature under the base. These larger-scale models are rare. Fine.

This model is in the more usual 1.18 scale and is also signed underneath by Keith. Fine.

Keith played an important role in the development of this car. Fine.

This is one of the rarest and most sought-after post-war Jaguar brochures. A small number of brochures were produced before the decision was taken to run with the V6 turbocharged engine. Most were then destroyed but a tiny number escaped into the wild. The one offered here is accompanied by a copy of the standard brochure for comparison. Both brochures are Fine, near Mint.

Part no SPM2047 21 x 18 opening out to 37 x 18. Branded XJ220 and crafted in beautifully soft nappa leather by Tumi. This is long out of production by Tumi and has been replaced by a nylon version.

17 x 12 x 6. Part of the same luggage set. Beautifully soft nappa leather embossed “XJ220” on the luggage tab and the inside wallet. Unused. Fine. Unbranded version of a similar holdall is on the Tumi website at £830, so here’s a chance to save a bob or two!

An elegantly embossed thick card press pack containing a 5-page press release embargoed to Wednesday 23rd October 1991 and a mono photo of the car. It is sometimes forgotten that the car unveiled at the hugely successful Birmingham launch in 1988 was the V12-powered concept car. The V6-powered production car was actually unveiled to the public at the Tokyo show in 1991, three years later. This is the press pack for that launch. Fine.

Entrant’s pack for the crew of NUB 120. This was Ian Appleyard’s record-breaking mount in the very early 1950s and is now in the JDHT collection. Still leads an active life, like many other cars in the collection and this 2004 run is a good example. Rare. VG.

This is the scarcest of their 1:18 scale Jaguar models. There was only one production run and it was not huge. As a result, these exceptional models carry a premium on the other AutoArt Jaguar competition models at this scale. Mint. Boxed.
