Hello to all modders with fuel economy in mind :thumbup:

I have to say I have not been a really ecomodder, but have been energy saver about 20 years.

I have a small call with very good consumption values for inside city drives. It is a Peugeot 107 (= Citroen C1 almost Toyota Aygo) which run about 181 mpg / per passenger seat.

For longer travels we have Renault Grand Espace 3 (built by Matra formula car manufacturer) space ship which run 185 mpg / passenger seat. And we are about to begin a new journey about 3700 miles with that in 9 weeks.

My cars run mainly 95 E10 because there has not been standard 95 available almost ten years. So real consumption is about 10% less compared to unleaded 95.

What engine does it have?


At least in theory, the mileage decrease for E10 would be around 4.75%.

My engine in Espace is petrol/gasoline 2.0L 16V F4R 700 without turbochargers.

Most powerful engine was F1 concept car twinturbo V10 with 780 hp engine. Top gear has tested the concept - see for it because I can not link it here.

In this F1 model one can see many ecomodding fixes. In my opinion the hardest to ecomodding is air hitting low rear axle.

Presumably the same engine of the only Espace I have ever seen in my hometown 25 years ago.

Cars having this petrol/gasoline engine were produced years 1999-2002 for Espace 3 phase (lift) 2.

Sure Renault F motor is used in other models too. In Espace 4 it is turbocharged. 16V (valves) is model indicator.

It replaced F3R which were used in Espace 3 phase 1 models. This is 8 valve version.

V6 engines were provided Nissan.

Edit: corrected F3R from 12V -> 8V

I have only seen 8-valve and 16-valve versions.
