After 1973, it was decided that the 2.4 litre wasn’t really fast enough for the 911, with the impending American emissions standards threatening to slow the model down to the point that ordinary Cadillacs would smoke its droopy tail. The solution: to take the 2.7-liter engine developed for the Carrera RS, detune it a bit, and make it standard across the board.  This made the 911 a very usable sports car for all driving conditions, especially when mated to the well-proven Sportomatic gearbox. 

The semi-automatic Sportomatic transmission had a conventional synchromesh gearbox in series with a torque converter and a normal clutch operated by a vacuum-controlled lever. To change gear,  the driver simply had to move the lever through a conventional H pattern. With no clutch pedal to press, this resulted in smoother changes than most drivers could achieve with a manual transmission. The effect on performance was minimal and to prove the point, works drivers Vic Elford, Jochen Neerpasch and Hans Herrmann gave a magnificent display of driving to win the 1967 Marathon de la Route in a 911R equipped with Sportomatic transmission. Elford also drove a Sportomatic as his daily car, using it to tow his caravan to race meetings all over Europe.

One of only 27 supplied to the UK, this RHD 911 2.7 Sportomatic is one of the rarest variants of the 911 available today. A narrow-bodied, matching numbers car, originally finished when new,  in metallic gold, MRX 164P was a some point repainted in black, though still retains its original Fuchs alloy wheels.

After a long period of storage this interesting 911 has recently been unearthed, and is found to be in a good state of health. The body appears to be solid and straight, with strong looking kidney bowls and B-pillars, although there is however some bubbling to the front headlamp bowls and sill covers.

Offered with a UK V5 document, this rare model presents its next owner with a perfect candidate for light restoration and re-commissioning.
