I started looking at ways to do my car months ago, and found little information.

Was about to do some serious number crunching when I came by this thread

106 friend!!!

Any chance, you could show us all how you constructed the tail? Did you keep the standard hatch and cut the inside out to leave a frame to attach the sheet metal too - giving you a hinge and a latch to hold it? I was going to do my tail floor a bit steeper providing I can keep the flow from underneath attached.

Are your wheels discs just held in place by a screw in the centre, the standard hub cap is beneath this?

I'm using the 1.5 Diesel engine in mine. It manages 55mpg (real) 45mpg (US) and I give it a hard time. The best I ever got from it was 84mpg imp but I've only ever managed that once.

So, finally an update on the Peugeot 106.

We wanted to have all the mods complete before end of MOT, but the first Corona-wave made us miss that deadline. Therefor we had to MOT the car. Although we thought we didn't do anything illigal (besides the camera mirrors, but we can replace those in a few minutes), we were still a bit worried. In the end, we only had to put some rubber on the sharp edges of the aluminum aero tail. So now the car is road legal for another year.

But we weren't satisfied with the results we were getting. We could only achieve around 1 liter per 25 km (+/- 59 MPG), whatever we tried. But we've found the solution!

We originally chose for a late model 106 because of multipoint injection, so we could make our own cylinder shutdown. We never thought of it again because of the misconception that it would be to complex. For around 30 bucks, we bought some connectors, wires and a switch, so we can interrupt the positive wires going to the injectors of cylinders 1 and 4. At idle, we can also switch them back, but at speed they won't switch back on. Something with the ECU probably, because when we turn the key and switch it back on, they will work. So we're probably going to make a switch to cut off the power of the ecu while coasting as well.

More importantly, the car drives amazingly well on only two cilinders. It's not powerfull enough to have proper acceleration, but it's more then sufficient to retain a cruising speed of 45-50 mph. And fuel economy was improved massively, we're now getting 1 liter per 35 km (82 MPG) and we think we can do even better on a route with less height differences. We think we might be able to push it to 1 l/40km (94 MPG) with the camera's mirrors on, and a flat and boring route with a cruising speed of around 45 mph.





Also note the self fabricated windscreen wipers with aero blades that sit much lower the the original ones, barely obstructing the wind flow anymore. (we've ditched the spring, so you can only replace wipers by taking the entire wiper arm off).

We made a steel frame welded to the original tail gate of the car:





We made cuts in the steel bars every 5 to 10 cm's with a grinder and then welded them back together to get the desired curve. We then made paper templates of the aluminium panels, that we formed on the car using metal working hamers and spanners:



So we nailed the panels to the frame while holding them tensioned and that worked surprisingly well. It turned out better the we expected.

We welded a bracket to the original steelies:



The we made a hole with thread in the brackets, to mount the aluminum wheel covers with a single bolt.

What a cool project and car to choose for this kind of modification.

Revisiting this forum has definitely fired back up the urge to get back to ecomodding (just as soon as I've finished ecomodding my new home).

Hats off to you, sir!

I think this thread can be moved to succes stories...

Today we drove 459 km's and we used only 12.12 liters of petrol. That's 2,64 l / 100 km or 89.08 US MPG! It was a route with mainly highways and we drove 75 km/h all the time on 2 cylinders. So not entirely representive for everyday driving but we're very pleased with the results. Mission acomplished. Thanks for the inspiration Eco Modders!

More info later.

Patiently awaiting further updates.

I’m gonna ask, is it not highly dangerous to be running half your cylinders? Many people say this a risky thing to do. The mileage increase is crazy, though.

Sure there might be some drawbacks under specific conditions. On a sidenote, when I was in my early teens, I considered it could be reasonable to replace a 4-cyl 1.0L car engine with a 500cc parallel-twin out of some motorcycle with a similar power rating - little did I notice how the substantially different power and torque curves and peak RPM bands would affect overall performance.
