* Size and weight: Larger limousines, especially those built on larger chassis (like a bus chassis), get significantly worse gas mileage than smaller ones.
* Engine size and type: A V8 engine will consume more fuel than a smaller V6 or even a hybrid powertrain (though hybrids are rare in limousines).
* Driving style: Aggressive acceleration and high speeds drastically reduce fuel economy.
* Maintenance: Proper maintenance ensures optimal engine performance and fuel efficiency.
* Type of limousine: A stretched sedan will have different fuel economy than a large SUV-based limousine.
You could expect anywhere from 8-15 MPG (miles per gallon), with larger, less fuel-efficient limousines likely falling toward the lower end of that range, and smaller, more modern ones potentially approaching the higher end. It's very unlikely you'd find a limo that gets better gas mileage than that.
