EXPLANATIONS
Writing of the new Triumph TR4 sports car last month I remarked that cool air refused to issue from the facia vents and that an indicated too m.p.h. called for 5,200 r.p.m. It Seems that someone forgot to tell me that a lever under the scuttle had to be used to bring the vents into use, while, although I was told that overdrive was not operating, it was not explained that the car had the low overdrive axle ratio. I look forward to clarifying matters when Leyland-owned Standard-Triumph-International submit a TR4 for the full treatment; meanwhile you can ignore the aforesaid criticisms. The comments on page 86x about the new Vauxhall Victor may give the impression that all versions have this new 4-speed gearbox. In fact, the 3-speed all-syncromesh box is used with the improved column gear change. The improved performance Vauxhall expected at the London Show will be called the VX 4/90 and will have the Victor body shell.—W.B.
