Electric - Biodiesel baby !

I wonder what kind of mileage the Aerocivic would get with a diesel engine from the Polo, or conversely what kind of mileage the Insight 1G would get with extensive aero mods installed. Currently, my 3 tank average is only running 3mpg below that of the Insight 1G

This is awesome!

For all those interested I've posted another YouTube video about the Insight 1G. This one shows the full hybrid functionality of the vehicle. The video can be found at:

Looks amazing. So what have you done mated the TDI to the insight gearbox?

I have just picked up a Lupo 3L this weekend. I didn't realise the turbo didn't come in untill 2000rpm i really could not tell when driving at all although i really have to take it our of auto to climb some of the very steep hills but the diesel is a hell of a lot better than my regular 1.4 100bhp petrol Lupo. I have to be at about 4,000-5,000rpm to pull up the hill very steep hills well in that. The 3L is 830kg what sort of weight is your insight with the TDI in?

re-gen braking and electric assist would be ideal for me as i go up and down some very steep hills on most trips.

Are you able to control the engine map as with the 3L?

We mated the TDI to the Honda Insight electric motor which is then mated to the transmission.

As a result of our ECU strategy we only had room for one tune at a time. In the interest of best fuel economy we put the Eco tune into the ECU. With this tune the turbo doesn't really come on line until 2,000 RPM+. We do have the ability to change the ECU tune for more power.

The Insight with TDI weighs approximately 907 kg.

Really amazing. Best of luck getting all of the kinks worked out.

80+ MPG is great!... have you considered showing this to anyone at Honda? Maybe they'll take notice?!

The oil pressure light should be a simple fix, I'd think, that only required using the original oil pressure sensor from the Insight motor in one of the TDI's oil passages, like the one that goes to the turbo. You could tee the line and put the sensor right in it.

No. We haven't shown the car to anyone at Honda. I'll see if I can't find a good address and send along a note. I have a feeling Honda won't respond. I haven't had a large company respond yet to anything I've sent along. Small fish, limited capital, crackpot idea and all that.

I'm working on finding a Bosch sensor to fix the nuisance oil light problem. After doing a little research it seems Bosch makes sensors that are normally open or normally closed under pressure depending on what different auto manufacturers specify. I just need to find the right one and I should have the problem solved (assuming the connector isn't different; we'll see).

I think you need an oil pressure sensor from an Audi. There's a guy that used a TDI engine in his Caravan, needed an Audi gasser sensor because it was different, but threaded right in.

As long as the new plug has the same number of wires, it shouldn't be a problem, right?
