MG Magnette MkIV
(1961 to 1968)
The Farina-styled Magnette had only been on sale for three summers when BMC announced a comprehensive redesign of all this family of B-Series cars. In the process, the Magnette moved from Mk III to Mk IV and became a much better car than before. The problem for the sales force was that it looked almost exactly the same, and its reputation never recovered from the early pasting it had received from the critics.
The Mk IV had a slightly longer wheelbase and wider wheel tracks, which was bound to give it more stability, but it also had anti-roll bars on the front and rear suspension. Not only that, but this was the time when BMC enlarged the standard B-Series engine size to 1,622cc, which meant that the Mk IV also had more power and torque than the Mk III.
The fact is that the Mk IV was a much better-developed car than the original, though even in this form it lacked the steering capabilities and the sheer sports saloon character of the well-loved ZA/ZB family.
It struggled on, unloved and mostly ignored by the public - as did its Riley clone, the 4/Seventy Two - for several years. By the end of the BMC era, sales were down to less than 1,000 cars a year, so its death in April 1968, just as BMC was also being killed off, was a merciful release.
