An excerpt from the August 1951 issue of Road & Track...which was an excerpt from the Jan-Feb 1951 issue of Sports Car magazine...
"In a recent regional news letter, the cornering powers of our 'J.2' are compared with another make and the fact that the 'J.2' holds the road like a leech up to certain speeds when it slides without warning, is mentioned.
Mr. Allard asks me to say that this is well known, but the speed at which this sliding occurs is greatly above the speed at which the other make mentioned starts to break away. At the speed where this breakaway occurs on other makes, the 'J.2' is rock steady and, if it is desired to corner at the maximum speed possible with our car, this must be done in the usual Grand Prix manner, in a four-wheel drift. The required angle of drift being maintained by conjuctive manipulation of steering and throttle.
When this technique is mastered we doubt if there is a faster sports car through corners extant than the 'J.2' Allard"
