An automobile is a highly engineered collection of complex components, each of which has its own lifespan and longevity characteristics. The MTBF (mean time between failures) of some components is expected to be smaller than the life of the car, as the replacement of these is considered part of regular maintenance.
In the example provided by the US DoE in its final rule, an electric car with an energy consumption of 265 Watt hour per mile in urban driving, and 220 Watt hour per mile in highway driving, results in a petroleum-equivalent fuel economy of 335.24 miles per gallon, based on a driving schedule factor of 55 percent urban, and 45 percent highway ...
EPA HWFET driving cycle. The "highway" program or Highway Fuel Economy Driving Schedule (HWFET) is defined in 40 CFR 600.I. [10] It uses a warmed-up engine and makes no stops, averaging 48 mph (77 km/h) with a top speed of 60 mph (97 km/h) over a 10-mile (16 km) distance. The following are some characteristic parameters of the cycle:
Along with a standard 10-speed automatic, our crew-cab test truck had four-wheel drive and was equipped with a 26.0-gallon tank, giving it a driving range of 700 miles. Read the Review Michael Simari
Specifically, for driving at an average of 60 kilometres per hour (37 mph), approximately 33% of the energy goes into exhaust and 29% is used to cool the engine; engine friction takes another 11%. The remaining 21% is split between rolling friction of tires (11%), air drag (5%), and braking (5%). [ 6 ]
Average miles driven per year: 16,585. Average price for a new model: $26,351. Price per 1,000 miles: $1,589. Data is sourced from iSeeCars.com and is accurate as of Apr. 30, 2024. More From ...
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.
A motorised bicycle allows human power and the assistance of a 49 cm 3 (3.0 cu in) engine, giving a range of 160 to 200 mpg ‑US (1.5–1.2 L/100 km; 190–240 mpg ‑imp). [ citation needed ] Electric pedal-assisted bikes run on as little as 1.0 kWh (3.6 MJ) per 100 km, [ 55 ] while maintaining speeds in excess of 30 km/h (19 mph).
