Hello from France
 

Hello here,
i'm Cuda47 from France.
40 yers old and interested by this forum to have more information.

Actually, i have a Renault convertible with a 2.0 turbo engine. I'm colse to 30 mpg with a daily se (2 x 17 km with cold start).

Welcome to the site.

Welcome to Ecomodder! :)

Thanks!
For people who does not know the model, it is like this car:

I bought a Turbogauge to improve the fuel consumption, but, for me it does not match well...

These are very rare in Brazil, IIRC they were only imported in 2007.

Hello cuda47! Welcome to Ecomodder:)

I would start with (partially) blocking your radiator and/or grille.
Also, if have a place to plug in you may want to invest in an electric heater for your engine, then in insulating the engine bay.

Blocking the radiator grill improve the engine heating, i would say, the engine is warming quicker.
For aerodynamic impact, it is poor.

I'm looking for the next car, not easy because i love tis convertible... But i need a car more daily use (more inside place), like a wagon or un van....

Even though a convertible might look cool, the unsuitability of a roof rack to expand the cargo capacity on demand becomes a PITA sometimes. Well, if it wasn't for some restrictions to the traffic of Diesel-powered vehicles according to emissions certification, I guess a 1.5dCi Mégane II Grandtour would be a good replacement...

Yes, this car is on the list....

If i "take the way" of Diesel, the 1.6 Peugeot / Citroen should be ok, and the 1.5 Renault too.

Even though their basic designs might be pointed out as quite ancient by now, these are great engines.

Yes.
I know both engines, and with an eo remap, it is possible to improve consumption :rolleyes:

Those remaps seem to be quite popular in Spain

I would be quite interested in the results if you do an eco remap of PSA's 1.6 HDI.

I recently switched from the 16v 1.6 HDI to the 8v 1.6 e-HDI and am impressed with the improvement. If it could be remapped to better focus on eco, then it would rock!

Considering that 16-valve engines were hailed as a great evolution around 20 years ago, it does sound quite surprising that PSA took the opposite route with the DV6. IIRC the reason claimed for that move was emissions control.

=> In Europe engines are often remapped, but in the way to change torque and power, sometimes, they are more eco...
My idea is not to touch these characteristic (homolgation), but to modify only the mapping point of a daily using.

I searched for Turbogauge, and it looks like a version of the ScanGauge made in the U.S.


If it is similar, there should be a feature that allows you to calibrate your readings to better match the car's actual consumption. You enter an "offset" fuel use value manually, or simply tell it how much fuel you used at each fill. After a few tanks, it should be pretty close.

I worked for the R&D département for this engine ;)

Cool!

How much do you have in Megane II CC 2.0 T ???

How much?

What is your mileage?

140 000km :thumbup:

Uuu, you have little ... :) I have almost 255,000 km. For me, it crashes a roller position sensor error: /

Hello je te,
I étudier thé engine behavior with thé Turbogauge.
I found something to do like eco-driving.
The fuel consumption have decreased from 8.2 To 7.3 l/100km only with that.
I Will have a look for pressure tires later.

Sorry for the T9 phone writting text...

I reach a fuel cs at 6.96 l/100 (33.8 mpg US) it is quite good, the first monthes i had the car i was around 8.5L/100 (27.7 mpg US).

I'm looking to change this car to have a car around 60 MPG target...

Hello cuda!

Bravo for the improvement. I had a Megane 3 RS before and I got that sort of fuel efficiency. Pulse and glide made a huge improvement in it.

Do you do short or long trips? Diesel could be a good thing for you in case of long trips.

If you do small trips, or trips with height differences, a lot of acceleration and braking, the main factor for fuel efficiency will be weight.

If you do long, constant and high speed trips, then aerodynamics are the key factor. You need to get a car with the lowest CdA (SCx) possible.

Et vive la France :)

Helo ptitviet,

Fuel saving is more difficult with the gasoline engine (Megane) than with my C3 Picasso (Diesel engine).
Behavior is different.

My using is daily trip 2 x 17 km with 2 cold start a day.
I have also a lot of heiht difference (not mountain of course).

I optimized the trip to have constant downhill to go to work, and another trip to have minimum variation to go back...

Roads are winding? (not straight) and pulse and glide is difficult. That explain my results.
On long trip, i can easily reach 6.4L/100....

I don't have low resistance tyre....

For next car, i'm looking for:
Citroën C4 3 doors
Ford Focus SW (Econetic model)

both in 1.6L 90hp Diesel engine.

If French drivers won't be so crazy behind the steering wheel, and if i don't have to "carry" my family, i'll by a Citroen Ax 14d...

How many km a year do you do for your daily job trip, and how many for longer trips/leisure/holiday?

Around 12 000km a year.
This is not really a money problem, i just want:
- A car were children can take place at the rear seats.
- A car to carry a lot of thing (DIY) whit rear seat lowering.
- A maximal economic car in the lower price....

Why?
Because i'm working on a classic car and i want to save a max of money on the daily car (the target is to divide car budget by 2....).

Since you do quite small trips and not a lot of km a year I think a petrol engine would be more suitable for you than a diesel. The diesel won't like very much being started from cold every day for "only" 17km.

And I would also pay attention to weight first (short trips, level differences).

Aerodynamics are less important for you, and an aerodynamic car will give you less inner space :)

=> I'm just looking for Diesel engine without DPF.
With downsizing, the engines are warming faster.
My wife has an 1.6 Hdi (90 No DPF), since many ears, no problem at all.

Befrore my CC i owned a fiat Marea we jtd, whit any fuel optimization, the fuel CS was around 5.5L/100.

What about a Peugeot Partner or Citroën Berlingo? It's quite easy to figure out why Argentinians and Uruguayans love these so much.

I thought about that, but front area is quite big...
