ISDERA (D)
The Isdera Imperator 108i was the creation of Eberhard Schulz, who had been an associate of Rainer Buchmann at b+b (qv) when he had created the b+b CW311. It was not surprising, then, that the Imperator was fairly close to that car and even used the periscope which replaced the more usual rear view mirror. The customer originally had a choice of Mercedes-Benz or Porsche V8 engines which promised the 0-60mph sprint in under five seconds. By 1990 the specification had settled and Mercedes-Benz engines, ranging from 3 to 6 litres, were offered in a tubular frame with independent suspension all round by coil springs and double wishbones. Bodies were of fibreglass. A Spyder version with a high T-bar and fussy styling behind it had presence but not, perhaps, line. By 1990 total production had reached about 24 each of the Spyder and Imperator.
