The BeamNG Hypermiling Challenge

This is a brand new challenge created by me, in which you must do whatever it takes to save fuel.
The goal of the challenge is to have the lowest fuel consumption for a given car, within the rules, which are as follows:

1- The map used in this challenge is Utah, USA, with the following route (only one lap)


2- Fuel consumption will be measured in L/100km, using the trip computer app (Place the trip computer app in your screen, and left click the app until it shows "Avg. Fuel Consumption") as shown in the following picture:


3- All modifications to cars are allowed, with the exception of removing body parts (such as doors, hood, fenders, headlights etc.) or glass.
Allowed modifications include (but are not limited to): Removing seats, swapping engines, changing wheels/tires, changing transmissions.

4- Only use vanilla game parts (engine mods, variety mods etc. are not allowed)

5- To show your fuel consumption post a screenshot of the game showing the trip computer with the avg. fuel consumption.

6- Minimum required speed of 32km/h or 20mph.


A controller, particularly a wheel, is recommended for this challenge as it gives you better control of the car.

Each car in the game will have different standards for fuel consumption, because 9L/100km is alot more impressive in a Barstow than it is in a Covet, for example. When you post your fuel economy results, make sure to tell us what car you're using.
Finally, fuel economy will be measured at the end of the course.

The following pic is an example and also my entry to the challenge.

 

nice challenge you really thought this true

 

Well time to start trying to see what kind of gas mileage I can get out of a moonhawk with a stage 4 supercharger
Edit: also are mirrors body parts?

...Not too fond of this track, I missed the first turn every time so far and I never realize until i already pass it...
--- Post updated ---

I got 17.5 Km/L with the stage 4 supercharger for the moonhawk.

 

That's not bad at all for 1400+ horsepower

I managed to squeeze an even lower consumption from the same engine, here's mine:

BTW why is your engine so hot?

 

3.4L/100km on Pessima HX w/ 13x5 wheels, 50psi tires, and 6sp transmission with 3.0 final drive. If you don't want to watch all five minutes of the run, click Direct Link and you'll have access to the scrubber so you can move the playback position.

 

Because I removed the radiator and was driving at around 3000-4000 RPM most of the time as well as driving one part a bit too hard.

 

I enjoy this; It is very fun. I will continuously update my list.

New Pessima 2.7 LX V6 Sport 5 speed manual, removed passenger and rear seats.

 

That's fantastic, considering your average speed. That reminded me to add a rule I forgot about ;p

That's a fantastic fuel consumption for a 2.7.

This is the Ibishu Miramar with the DOHC 1.6 engine, 3.90 differential, and full race suspension. It has maximum camber on both front wheels and 50psi tires all around. I also removed the passenger seat and rear seats.
I got 3.8L/100km with an average speed of 42km/h

 

Come on people, you can do better than that!



2.7L/100km in the Covet.

Setup:

1.5L SOHC (EFI) engine
6-speed manual racing transmission with 0.7 sixth ratio
13x5 wheels with 90-profile bias ply tires at 50psi
Front and rear swaybar delete
Carbon fibre hood

 

I find it pretty funny how mostly everyone so far is using small fuel efficient cars to get the best mileage... and here I am coming in with this big whale of a car that didn't have gas mileage in mind... instead a smooth and comfortable ride was in mind, and it's V8 powered. Anyways here's my take on what fuel economy I can get out of a stock Gavril Grand Marshal V8 automatic.
Controller used: An XB360 mini controller plugged straight into the pc



I also kept my engine speed at around 2k rpm while keeping my overall speed between 40 to 50km/h the whole lap.
I also kept it in "D" the whole way through and the GM stayed in 2nd gear... though my real car's automatic irl would have up shifted to the higher gears when not interacting with the gas pedal while moving along.

Imperial figures:
Average speed ------------------- 26.9mph
Total distance traveled ---------- 2.4mi
Average Fuel Consumption --- 25.4mpg

Just out of curiosity, I decided to drive on the 5km highway loop of Utah traveling between 80 to 90km/h at roughly the same engine speed (2k rpm)
and I got 11.7L/100km as the average fuel consumption which isn't that much more fuel being burned compared to driving really slow in second gear.

 

Here's my run with the 200BX:
4.7L/100km with the stock 2L engine, 6 speed manual with a 0.5 6th gear, and the same 13x5 wheels. Avg speed of 51kph.


Admittedly, I did give it some gas at some points just to get the speed going.

 

Well I know this doesn't count because it's a modded car but I thought I'd try anyways cause this car is super realistic...

I tried with this 1980 Oldsmobile 98 Regency its completely stock with an olds 350 v8 and 3 speed automatic transmission.
I know its supposed to be in liters per 100 km but I converted it from mpg. So I got 8.71 Liters/100km
Average speed was upper 30's
