The second Bi-motor Scirocco was created by the VW development department. This incarnation used two 16v engines. Each engine gave a power output of 141 bhp. A special bodykit was grafted onto the car to cater for the Audi Quattro alloy wheels.
The 280/4 was finished to a much higher standard than the 360/4, maybe to try and push for a limited production run which sadly never came to fruition. The grill for the rear radiator is neatly incorporated between the tail lights. The number plate is re-located into the new bodykit. The 280/4 instrument cluster had two rev counters, two oil temp gauges, two water temp gauges and a single digital speedo. It featured 15″ Audi Quattro Fuchs alloy wheels.
It could achieve 0-60 mph in 4.1 seconds and a top speed of 180 mph (290 km/h).
