220 Clean Diesel Bus Order Is Greyhound's Largest in 20 Years

WASHINGTON, April 2, 2013 /PRNewswire-USNewswire/ -- Greyhound's announcement that it has placed orders for 220 new clean diesel, low emission buses highlights the major advancements in diesel fuel efficiency and environmental gains, according to Allen Schaeffer, the Executive Director of the Diesel Technology Forum.

"Congratulations are in order for Greyhound and the two manufacturers - Motor Coach Industries and Prevost of the Volvo Group - for this major order of the newest clean diesel bus technology," Schaeffer said.  "These new buses will offer the most modern and advanced clean diesel technology to Greyhound's national fleet, which is the largest provider of intercity passenger service in North America.

"Because of its safety, reliability and efficiency, diesel is the predominant power source for public transit, school and intercity bus services nationwide.  It's extremely noteworthy that Greyhound Bus Line serves 3,800 destinations across the country and connects communities with a 100 percent diesel bus fleet," Schaeffer said.

"Diesel buses are the best source of transportation for Greyhound's expansive service area because of the efficiency and power needed to dependably and safely transport 25 million passengers throughout North America every year."

Greyhound Lines Inc. officials say the order is the company's largest bus order in more than 20 years and will make their fleet "one of the youngest and most environmentally friendly in the industry."

Clean Diesel Bus Technology Has Reduced Particulate Matter and NOx Emissions By 98%

Diesel power systems have been undergoing revolutionary technological advancements that have already achieved dramatic reductions in emissions for urban buses and highway engines. Advances in emissions-control systems and ultra-low sulfur diesel fuel (ULSD) are helping clean diesel engines achieve emissions performance equivalent to compressed natural gas (CNG) and other alternatives.

"Today, EPA regulation have virtually eliminated emissions from new diesel buses - reducing particulate matter (PM) and nitrogen oxides (NOx) by 98 percent from 1988 levels," Schaeffer said. "In addition, new technologies are also being used to upgrade older diesel engines which can reduce key pollutants from existing bus fleets by up to 90 percent.

"Because of these major advancements, clean diesel buses offer significant operational advantages over many alternative fuels, and assure reliable, durable, and cost-efficient bus transportation.

"Businesses and governments no longer have to turn to alternative fuels like CNG for greener operations.  They can now invest in clean diesel technology without the higher acquisition, facility and fueling station investments required with CNG," Schaeffer said. "While CNG fuel prices are lower than diesel at this time, that's just one part of the equation and there are significant other factors to consider.  Clean diesel buses are 20 to 25 percent less expensive than CNG buses, and do not depend on the separate fueling infrastructure and all of its attendant installation and operating costs required for CNG.  

"The new clean diesel technology is ideal for Greyhound's extensive intercity route system.  Diesel fuel is widely available in every area throughout the country, allowing for rapid shifts for Greyhound to serve new riders and routes.   And new-generation clean diesel engines are typically achieving five percent or better gains in fuel efficiency compared to previous generations.

"On a similar note, major city public transit systems are relying on both clean diesel and diesel-hybrid technology to improve efficiency and reduce emissions," Schaeffer said.
