Zender’s aerodynamic experience was apparent: “Along the leading edge of each front wing and up the A-pillar are strips of the same material designed to keep the air flow as uniform as possible as it goes over the roof to be met by a massive – by toad car standards – rear wing, which has a pair of rather melodramatic buttress supports at each side of the tailgate,” which apparently were “purely for show”.
Along with the “two tone graphic treatment” on the outside, the inside was a suitably 80s cool affair.
“The entire facia and centre console are covered in soft blue leather, as are the loudspeaker panels in each door,” Autocar described. “The normal oddments space under the steering column is fitted with a cassette storage system. The front seats have been replaced by deep Recaro buckets and are upholstered with a luxuriously padded, blue velour material, which looks superb, but could prove less than satisfactory in the long term,” we quibbled.
“The quality of the work described so far is exemplary if a little garish. The car certainly is eye catching,” Laurence said.
It wasn’t just what met the eye that had been fiddled with, though. Zender had also altered what was going on under Scirocco’s bonnet.
“Theroetically, the engine conversion is an interesting one,” we said. “The ingredients are simple, perhaps too much so, for the turbocharger installation – designed and carried out by tuners, Dr. Schrick near Cologne, a company of considerable German reputation – is literally a “bolt on” arrangement with remarkably few changes to the standard 110 bhp, fuel injected GTI engine.”
From there, things actually got a little bit worrying: “What’s more, the conversion includes an air to air intercooler which dramatically increases the volume of charged air, therby creating potentially dangerous internal pressure on the normally aspirated standard engine.
“It seems petulant to be so negative about a car we’e not had the chance to drive – because of a blown engine – but it does appear the position of the turbocharger and wastegate could cause overheating problems because of their positions a long way away from any worthwhile cooling air flow.”
Those two components were buried deep within the induction manifold at the rear of the engine, so Laurence indeed had a point.
The Z40 Scirocco was as fast as it was dangerous, though.
“Zender claim a 134mph top speed and a 0-62 time of 7.6sec for the car.
"Surprisingly, for a car with such increased performance – now 143 instead of 110bhp – the only chassis modification is a slightly reduced ride height caused by the fitting of Koni dampers front and rear, while the brake system remains the same standard disc/drum set-up.”
Despite the cool looks, Autocar were disappointed with the apparent lack of thought that had gone into the souped-up Scirocco.
“What was originally a show car has failed to appear as a viable road alternative, when customers have started knocking on the door,” we lamented, “Zender claim to have taken 16 order so far and expect the series to total no more than 200 units.
“It’s a pity that Zender and Schrick, both companies with good reputations and excellent work on other conversions, have been lured into producing a car so underdeveloped.”
Apparently, aerodynamic specialists Zender’s creation had never even seen a wind tunnel.
The Z40 Turbo cost 50,000 Deutschmarks, which was the equivalent of £11,400 – that would be around £39,500 today.
Autocar concluded: “Maybe if we had driven the Z40, our conclusions would be different, but somehow, on paper, it just doesn’t feel right.”
Zender is still in business today, and continues to modify sports cars to similar effect. However, we could find very little information on the Z40 – if you know anything, please email me at email@example.com.
