ok, and its not that hard to make, just make the worst engine possible.

The biggest bug in Automation (the latest version) is this: I've make a engine with 7.45% of efficiency, but needs only (installed in a car) 0.89l/100km (lol!), but with other engine with the same number of cylinders, type of cam, materials... with a efficiency of 35.6%, reaches a fuel consumption of 4.6l/100km (and this engine is a bit lighter!).

I'm searching the engine file to post here.

I think fuel consumption determines on efficiency and TQ to HP ratio with the least amount of air coming into the engine with minimal effort and resistance.

Fuel consumption is based on how much fuel is used to make one horsepower for one hour. In my engine, 0.198 lbs of fuel is used to make one horsepower per hour. The key to getting cars to have good fuel economy is to look at the green line on the graph in the engine designer. The lowest point on that graph is the engine's most fuel efficient point, and usually is where your car should cruise along sipping fuel. If that point is too high, say something like 0.550 lb/hph at 3,500 RPM, you should gear the car for a lower RPM when cruising. It seems that most of my cars love to drive around 1,800-2,200 RPM at 65-75 mph (105-120 km/h).

I just made engine with 63.84% fuel economy but uses Ultimate fuel, does it counts?

This is just the engine I put in my Derrick MK1 SUV
I could possibly make it more efficient

link for the SUV, it got 30 mpg (6.720417 liters per 100 km) and weighed 3800 pounds (1727.27 kilos) on premium
