Highest MPG for a non-hybrid: Mitsubishi Mirage
Best non-hybrid MPG: 2014 Mitsubishi Mirage?
Mitsubishi says its new Mirage subcompact will get the best MPG of any non-hybrid: 44 mpg (US) highway, 37 city. (Some drivers are already beating that in various economy driving contests.) How? An efficient 1.2L, 3-cylinder engine, very light weight and aerodynamic design.

What is Ecomodding?
Welcome to EcoModder.com, an automotive community where performance is judged by fuel economy rather than power and speed. EcoModders employ a combination of vehicle mods, driving techniques, and common sense to squeeze every penny out of the pumps. Reasons for becoming a member range from the economical to the ecological. More info about where EcoModding came from.

The Zing! (Custom-built prototype hybrid tadpole trike) The Zing! (Custom-built prototype hybrid tadpole trike)

The intention is for the production version is to have a 7.2kWh lithium pack which will have a maximum electric-only range of ~70 miles or about 40 miles in everyday driving. Then the generator starts up and you can keep driving, similar to the Chevy Volt.

Kill Switch (EOC): Where did you install your activator? And what did you use? Kill Switch (EOC): Where did you install your activator? And what did you use?

Shutting off the engine in a manual transmission car while coasting or when stopped (with any transmission) is an advanced efficiency driving technique that can save a lot of fuel. An ergonomically placed kill switch makes the process easier, safer, and saves wear on the ignition switch. This thread shows multiple installations.

Streamlined Citroen ZX Streamlined Citroen ZX

CitroX describes his project: "This was actually the experimental part of my master thesis. I needed to analyse how drag effects a moving vehicle and how it's aerodynamics could be improved. Orginal car ABA testing did 31.36 mpg @ 56mph. Modified car same road same speed but warmer weather did 49 mpg. This mpg increase is very close to the one that was theoretically estimated."
