Weber efi Description

Lagonda (Weber efi)

Unveiled: January 1986

In production: 1986 — 1987

Chassis numbers: 13464 - 13645 (production)

In January 1986, announced at the New York Autoshow, beginning with chassis 13464, alongside the AM V8 saloon and V8 Volante, the Lagonda received the V585 engine with Weber-Marelli electronic fuel injection. This increased the quoted maximum power output to 300 bhp @ 5,000 rpm in Europe, with maximum torque of 320 lb.ft), but still around 24 bhp with the Federal LFA version. The interior and exterior remained unchanged from the previous V580 carburettor car.

Vacuum Fluorescent Instrumentation

First seen at the 1986 Paris Motor Show, new vacuum fluorescent (VF) instrumentation with graphical display, as used on the range topping Opel Monza GSE was introduced to replace the bespoke CRT system. These instruments, first used from chassis 13505 continued to be used on the Lagonda until the end of production. The backlit side binnacles were dropped and more conventional push switches were mounted either side of the green on black instrument display.

The V585 equipped Lagonda is the rarest derivative with only 76 examples built; 41 with CRT instruments and 35 with VF instruments.
