From Track to Road – The Birth of the Austin Healey 100M

Originally based on the successful BN1 model introduced in 1953, the 100M represented an evolution of Healey's racing ambitions. After impressive performances at Le Mans in the early 1950s, Healey saw an opportunity to offer road-going customers a taste of the track experience. Thus, the factory-produced 100M was launched, limited to just 640 examples, making it a highly sought-after collectable today.

BN1 to BN2 – Evolution of the Healey 100

The BN2 platform provided crucial enhancements over the earlier BN1, setting the stage for the high-performance 100M:

  • Improved Transmission: A robust 4-speed gearbox with overdrive.
  • Enhanced Braking: Larger 11-inch front drum brakes.
  • Minor Refinements: Better axle ratios, improved suspension components, and distinctive design features, including subtle alterations to the front and rear wings to enable the stylish two-tone paint combinations.

Iconic Two-Tone Paint Schemes of the Austin Healey 100M

One of the most visually striking features of the Austin Healey 100M was its distinctive two-tone paint scheme, with approximately 70% of the 640 factory-built cars proudly sporting this stylish look. Popular combinations included Old English White over Black, Reno Red over Black, Healey Blue over White, Black over Reno Red, and Florida Green over White, each carefully chosen to accentuate the car's flowing lines and sporting character.

Perhaps the most memorable, however, was the unique Black over Pink combination used exclusively on the car displayed at the 1955 Earls Court Motor Show. This one-of-a-kind Healey later competed in the Bahamas Speed Week and has since been meticulously restored, preserving its original eye-catching colours. These vibrant colour schemes set the aesthetic tone for later Austin Healey models, influencing the iconic two-tone combinations used on the BN4 through BJ8 series.

Here's a table listing all the colours available across these models. For those curious to see the remarkable Black over Pink colour scheme in full glory, a photograph and detailed history of this special car can be found here on Bring a Trailer

What Makes the Factory 100M Special?

The genuine factory-produced 100M models featured performance modifications directly inspired by Healey's racing exploits:

These modifications weren't superficial—they transformed the car into a genuine performance machine capable of spirited driving both on and off the track.

Factory 100M vs Retrofitted 100s – Spotting the Difference

Understanding the distinction between factory-built and converted 100Ms is essential for collectors and enthusiasts alike:

  • Documentation: Factory-built cars are recorded with the British Motor Industry Heritage Trust, establishing authenticity.
  • Bonnet and Badge: Original 100Ms always featured a factory-fitted louvered bonnet and leather strap, along with the distinctive "M" badge.
  • Performance Equality, Historic Authenticity: While retrofitted models replicate the performance, genuine factory-built examples hold greater historic and market value.
