1973 1/2 Porsche 911 T Sportomatic

6 Cylinders 2.4L

Interesting fact about the 73 1/2 911T, First model to switch to CIS (Continuous Injection System) from MFI (Mechanical Fuel injection)

It was a relatively simple system when compared to that of the end-of-the-line CIS on the '83 SC. By the '84 model year, the CIS was history, being replaced by the Motronic Digital Motor Electronics.

This particular car is also a rare sportomatic
the Sportomatic gearbox, introduced by Zuffenhausen in 1967 and based on the 905 unit, was an effectively clutch-less manual system that allowed the driver to change gear by simply pulling the gear lever through its standard H-pattern movement.

This allowed the car to come to a halt without the engine stalling or the driver having to physically engage neutral.  Due to the torque converter, there was no mechanical connection between the engine and gearbox. Therefore, a ‘Park’ mode was added to lock the lay shaft when the car was parked.
Confusingly, Sportomatic gears were labeled L, D, D3, and D4.
L (‘Low’) was similar to a standard first manual ‘box’s first gear however, Porsche encouraged using D to pull away unless on a steep incline or inclement weather. ‘D’ and ‘D3’ (note no ‘D2’) were slightly shorter ratios than second and third in a standard unit, however ‘D3’ was slightly longer, acting as an overdrive.

The color is amazing, yellow gold metalic and the condition of this car is really good
