Greyhound's fuel efficiency
Greyhound buses have come a long way in terms of fuel efficiency, especially when compared to older models. While late 1940s Greyhounds with Detroit-Allison uniflow engines achieved 9 to 12 miles per gallon (mpg), modern Greyhound buses are far more efficient, with a maximum passenger miles per gallon (PMPG) of 330 when fully loaded with around 60 passengers. This translates to approximately 5 to 6 mpg.
The significant improvement in fuel efficiency is due in part to advancements in engine technology and the implementation of stricter environmental standards. Today, Greyhound buses meet the latest Environmental Protection Agency (EPA) standards for carbon monoxide and hydrocarbon emissions. As a result, Greyhound claims that their buses produce only one-third of the carbon dioxide per passenger per mile compared to hybrid vehicles and even less when compared to gasoline-powered cars.
The fuel efficiency of Greyhound buses is also evident when compared to other modes of transportation. For example, airplanes flying domestic routes average 42.6 PMPG, while intercity buses at 80% capacity can achieve 250+ PMPG. Greyhound buses, known for their high occupancy rates, further enhance their fuel efficiency by carrying more passengers per gallon of fuel.
While the exact fuel capacity of a Greyhound bus may vary depending on the model and year, estimates suggest that they can hold around 100 gallons of diesel fuel. This fuel capacity, combined with their improved fuel efficiency, allows Greyhound buses to cover long distances efficiently, making them a popular choice for intercity travel.
In summary, Greyhound buses have made significant strides in fuel efficiency, reducing their environmental impact and providing a cost-effective mode of transportation for passengers. The combination of modern engine technology, stringent emissions standards, and efficient fuel usage contributes to their overall fuel efficiency, making Greyhound buses a more sustainable option for long-distance travel.

Greyhound's engines meet EPA standards for emissions
A Greyhound bus can hold around 100 gallons of diesel fuel. Greyhound's engines meet the latest Environmental Protection Agency (EPA) standards for carbon monoxide and hydrocarbon emissions. The company claims that their fuel efficiency means that each bus generates just one-third of the carbon dioxide per passenger per mile compared to a hybrid vehicle (and even less compared to gasoline cars). Given that Greyhound buses travel over 5 billion miles annually, this is a significant environmental consideration.
The EPA has been actively regulating emissions from heavy-duty vehicles, including buses, to reduce their environmental impact. In 2011, the EPA, in coordination with the NHSTA, issued greenhouse gas emissions and fuel economy standards for medium and heavy-duty trucks manufactured between 2014 and 2018. This was known as the Phase 1 Greenhouse Gas Rule. In October 2016, the EPA and NHTSA jointly finalized the Phase 2 standards for medium and heavy-duty vehicles for model years 2019 to 2027, aiming to improve fuel efficiency and reduce carbon pollution.
In August 2021, the EPA announced the Clean Trucks Plan, intending to reduce greenhouse gas emissions and other harmful air pollutants from heavy-duty trucks through a series of rulemakings. The first rulemaking, the Heavy-Duty Engine and Vehicle Standards, was signed into law in December 2022. This was followed by the Phase 3 greenhouse gas rule for heavy-duty engines and the multi-pollutant emissions standards for light and medium-duty vehicles, both signed in March 2024, thus completing the Clean Trucks Plan.
Greyhound's compliance with EPA standards is a positive step towards reducing the environmental footprint of its operations. By meeting the latest emissions standards, Greyhound contributes to the broader efforts to mitigate climate change and improve air quality. As the EPA continues to revise and strengthen its regulations, it is essential for companies like Greyhound to stay committed to adopting environmentally friendly technologies and practices.

Greyhound's older model bus fuel capacity
Greyhound Lines, Inc. used the GMC PD-4501 Scenicruiser from July 1954 until the mid-1970s. The Scenicruiser was a three-axle monocoque two-level coach with 10 seats on the lower level and 33 on the upper level, for a total of 43 seats. The fuel tank of the Scenicruiser could hold 180 US gallons (150 imp gal; 680 L).
The Scenicruiser was manufactured by General Motors (GM) and 1001 were made between 1954 and 1956. The bus became an icon of the American way of life due to its presence throughout the United States and its popularity with travellers. The distinctive design, a result of seven years of effort by Greyhound and GM Truck and Coach Division, featured a split-level layout with the driver's area and entrance on the lower level and the passenger seats on the upper level.
The Scenicruiser's power was originally provided by a pair of GM Diesel 4-71 four-cylinder engines of 160 HP each, connected by a fluid coupling and arranged in a shallow V formation. Two engines were necessary because GM had not yet developed a V8 version of its Series 71 Diesel engine. The fuel efficiency of Greyhound's modern fleet is impressive, generating just 1/3 of the carbon dioxide per passenger per mile compared to hybrid vehicles.
However, the Scenicruiser had some significant problems, particularly with the drivetrain and the cracking of the frame structure around the side windows in the rear quarter of the coach. In 1961, all 979 remaining Scenicruisers were rebuilt with 8V-71 engines and four-speed manual Spicer transmissions by the Marmon-Herrington Company, costing Greyhound over $13 million. Despite these issues, the Scenicruiser's popularity inspired GM's later PD 4107 and PD 4903 Buffalo bus models, which featured a less obvious "second level" and improved side windows.
