I’m trying to build a practical Eco Car to test Fuel Consumption Reduction by reducing Throttle Losses.
What I am doing right now:
2012 Car, all Aluminium Monocoque, like an Audi A-2 (I may try Fibreglass next)
It’s the 2.0m Wheelbase Mini Knockoff with the Wagon Body, FF layout
Double Wishbone Suspension all around.
10 inch Wheels, 125 Width, Maximum Radius, Hard Compound
All Aluminium 250cc 3 Cyl: 50mm Bore, 42.5mm Stroke, Cast Internals, Low Friction.
Compression. 12.0, 5V Head, DOHC
Direct EFI Per Cylinder
RPM Limit 12000
Long Tubular Exhaust, Hi-Flo CAT, only 1 Baffled Muffler
All Qualities at 8
Result: 25hp at 7100RPM
27NM at 5100
650kg in BeamNG
Top Speed: 90kph in 4th
86 in 5th
Gearbox and Wheels are all Set at 12 Quality
Theoretically this should enable me to get good Fuel Consumption, but I’m only getting 6.2l/100km.
Top Speed is also very low, a 29hp Citroen 2CV already gets 110kph, a Trabant 601 with 23hp would get 100kph Top Speed easily.
I have 2 more HP, am just as light yet slower with pretty high Quality Parts and the Trabant has Wider Tires.
My 38HP NA Version is at 8.0l and 105kph
My 30hp Turbo Version does 96kph and 6.5l/100km
So my Car is loosing a lot of Speed somewhere, and the Engine drinks a lot, far more than I would expect for a Car like mine.
