SAINTE-CLAIRE, Quebec — Prevost has confirmed its EPA 2027 Volvo D13 engine meets new emissions standards from the U.S. Environmental Protection Agency and California Air Resources Board, clearing the way for its use in model year 2028 coaches.
The new standards reduce permitted nitrogen oxide emissions by more than 80% compared with current limits.
Prevost representatives announced the certification during the International Motorcoach Group’s Strategic Alliance Meeting in Wichita, Kansas, where they briefed motorcoach operators on the new engine and changes they can expect.
The Volvo D13 engine and its aftertreatment system have undergone more than 2.5 million miles of testing across the Volvo Group, according to Prevost. Certification from both the EPA and CARB means model year 2028 coaches equipped with the engine will be eligible for registration throughout the United States and Canada, including California and states that have adopted CARB standards.
“Meeting compliance should not require our customers to start over,” said François Tremblay, president of Prevost and Volvo Group Canada. “We take that commitment seriously. Advanced technology and being part of the Volvo Group allow us to move the product forward while protecting the confidence customers have placed in us.”
The EPA 2027 update includes changes intended to meet the stricter emissions requirements while retaining a powertrain familiar to Prevost operators and maintenance teams.
The EPA- and CARB-certified Volvo D13 is paired with a simplified “one-box” aftertreatment system that replaces the previous multi-component configuration. Prevost says the design places service points within reach from the ground and is intended to reduce time spent on emissions-related maintenance.
Other changes include a redesigned air intake, air dryer and charge air cooler, along with a translucent coolant surge tank and 48-volt alternator.
Volvo engines have powered Prevost coaches for nearly two decades. As part of Volvo Group, Prevost provides engine, parts and service support through a single point of contact.
Prevost has also launched an online resource with information about the EPA 2027 engine, including materials designed to help motorcoach operators plan future purchases and prepare their maintenance operations for the changes.
