On May 5, 2013 I posted a story about the Austin-Healey 100. In that post I said that I would follow-up with some information about the Austin-Healey 100M, which was a performance version of the base Austin-Healey 100. This past weekend I was at a car show at the Endicott Estate in Dedham, Massachusetts and saw an Austin-Healey 100M that had competed in this year’s Mille Miglia rally in Italy.
1954 Austin-Healey 100M
The Austin-Healey 100M was created to provide a model with higher performance than the production Austin-Healey 100, but with a lower cost than the more racy Austin-Healey 100S.
Note The Louvred Hood On The Austin-Healey 100M
The appearance of the Austin-Healey 100M was changed from the production 100 by installing a louvred hood with a hood strap and a two-tone paint combination. This particular car has also had the front and back bumpers removed.
Wire Wheels Were Standard On All Austin-Healey 100 Models
For the purposes of judging the car at the car show, the officials wanted the top up on all convertibles and the hood up on all cars. While this might be fair to check on the condition of the cars, it is not the best way to display the smooth lines of the Austin-Healey 100M.
The Austin-Healey 100M Was Also Know As The BN2.
The Austin-Healey 100M was built from 1954 to 1956. A total of 1,159 Austin-Healey 100M cars were built, although I have also seen a total production figure of 3,924 BN2 cars, but I believe that the larger number includes standard 100 models with a four-speed transmission, in addition to the true 100M models.
From the Rear The 100M Looks Just Like The Production Austin-Healey 100
The Austin-Healey 100M Has A 2,660cc Four-Cylinder Engine
The Austin-Healey 100M had a slightly improved 2,660cc engine that produced 110 horsepower compared to the 94 horsepower engine in the standard Austin-Healey 100. This extra horsepower increased the top speed of the Austin-Healey 100 to 118 miles per hour from 111 miles per hour. The 100M accelerated from 0 – 60 miles per hour in 10.0 seconds compared to 10.3 seconds in the standard Austin-Healey 100.
The power curves for both the production Austin-Healey 100 and the 100M are shown in the following graph. These curves were taken from the book “The Healey Story” by Geoffrey Healey. This is a very good reference book written by a man who was in the middle of the development of the Healey and Austin-Healey cars.
Power Curves From The 100 and 100M Austin-Healey Engines
This car was entered in this year’s Mille Miglia rally. I understand that the car had a mechanical problem, but had completed a sufficient portion of the rally to be considered as a finisher.
The Interior of This 100M Looks Essentially In Standard Condition
The image below shows the dash from of the passenger or navigator’s seat. There are two pieces of Velcro on the dash which suggests that they were used to mount watches/clocks for the purpose of the Mille Miglia rally.
The Interior Of This Car Was Very Well Restored
The car was presented with its Mille Miglia livery. The owners of this car must be very proud that this car was selected for eligibility in that magnificent rally. It is not often that a car that has competed in the Mille Miglia shows up at a local car show.
The Mille Miglia Decals Are An Impressive Site
The Austin-Healey 100M is an impressive car, but even more so with this car, as it was selected to compete in the Mille Miglia.
