Re: 376 MPG
The "car" was a stripped shell without even a proper seat. No transmission (straight chain drive off the engine to the rear axle), no radiator, 500 ml fuel capacity, hard rubber tires and no suspension. This thing was never driven far enough or hard enough to need a cooling system!
In real-world conditions I can go faster further and more comfortably more safely using my bicycle, and instead of requiring nasty petrol I can do it powered only by 500 ml of 5% ABV 100% eco-friendly barley-based fuel.
