The Lagonda Vignale was commissioned by AML (already fully owned by Ford) from Ghia Design (also part of the Ford family) to be shown at the 1993 Geneva Salon. The exterior design was by Moray Callum - an interesting co-incidence as the Geneva Salon 1993 was the first appearance of the DB7, the work of Moray's brother, Ian.
This somewhat large car was built on a Lincoln chassis with Lincoln independent front and solid self-leveling rear suspension and was powered by a 4.6 liter (190bhp, 260 lb/ft) Lincoln Town Car V8. The reality of the concept is that physically, it had no recognizable AML parts at all. But, had this fabulous car made production (and many thought it would), the chassis would have become an extruded aluminum affair. The suspension was to be fully independent, and the engine would have been a 6.0 liter V12. While these features never made it into a production Vignale - they are the same as found in the V12 Vanquish.
