U.S. flex-fuel vehicles are optimized to run on a maximum blend of 15% gasoline with 85% anhydrous ethanol (called E85 fuel). This limit in the ethanol content is set to reduce ethanol emissions at low temperatures and to avoid cold starting problems during cold weather, at temperatures lower than 11 °C (52 °F). [4]
[28]: 11 By comparison, the conventionally-powered LLV on the same driving cycle returned fuel consumption of 0.22 L/km (11 mpg ‑US) at −20 °C (−4 °F) and 0.16 L/km (15 mpg ‑US) at 20 °C (68 °F). [28]: 15 This was followed by a larger fleet test, consisting of 500 Electric Carrier Route Vehicles (ECRV) from 2000 to 2003.
The CAFE achieved by a given fleet of vehicles in a given model year is the production-weighted harmonic mean fuel economy, expressed in miles per US gallon , of a manufacturer's fleet of current model year passenger cars or light trucks with a gross vehicle weight rating (GVWR) of 8,500 pounds (3,856 kg) or less (but also including medium-duty ...
MPGe is used by the United States Environmental Protection Agency (EPA) to compare energy consumption of alternative fuel vehicles, plug-in electric vehicles and other advanced technology vehicles with the energy consumption [1] of conventional internal combustion vehicles rated in miles per U.S. gallon.
Fuel consumption monitor from a 2006 Honda Airwave.The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.
Motus is a workforce management company headquartered in Boston, Massachusetts, [1] [2] that offers vehicle reimbursement, fleet management and business intelligence solutions. This includes mileage reimbursement, BYO programs, Managed Mobility Services and living cost intelligence.
Highly developed fleet management and vehicle telematics systems collect a full range of data in real-time and for transport and fleet managers. By combining received data from the vehicle tracking system and the on-board computer, it is possible to form a profile for any given driver (average speed, frequency of detours, breaks, severity of ...
Fuel efficiency is dependent on many parameters of a vehicle, including its engine parameters, aerodynamic drag, weight, AC usage, fuel and rolling resistance. There have been advances in all areas of vehicle design in recent decades. Fuel efficiency of vehicles can also be improved by careful maintenance and driving habits. [3]
