Rear end ratio is still the same 2.64 but with 5th gear the engine is turning 20% slower in paper. In reality it's closer to 25% slower since the stock 722.3 lacks a locking torque converter.
I use AC in SoCal almost all the time.
The 300D weighs about 500lbs less than the SDL and has a better drag coefficient so I don't think the 126 body could match these numbers but a manual swap should offer a similar % fuel economy gain.
