MELROSE PARK, Ill., (May 19, 2010) – Under a new multi-year agreement, Navistar Engine Group will supply its advanced V8 turbo diesel engine to Tiffin Motorhomes, Inc., a leading maker of Class A recreational vehicles. Beginning in June, MaxxForce® 7 engines, manufactured in Huntsville, Alabama, will power Tiffin’s new Allegro Breeze® RV, manufactured in Red Bay, Alabama.

“We’re always looking for new ways to offer more value to our customers, and we’ve done it again with this new high-end, smaller coach”, said Bob Tiffin, CEO of family-owned Tiffin. “The Allegro Breeze is wonderfully maneuverable, easy to park and fun to drive thanks to one of the most powerful, durable and fuel-efficient engines on the market.”

The V8 diesel pushers will be fully compliant with applicable EPA emissions standards. Tiffin will use 6.4-liter MaxxForce 7 engines rated at 215 horsepower and 560 lb.-ft. torque.

“MaxxForce engines fit perfectly with Tiffin’s reputation of providing high value and low cost of ownership, while introducing innovative products,” said Eric Tech, president, Navistar Engine Group. “We’re proud to add another industry leader of U.S.-built motorhomes to our list of partners.”

This past November, a concept model Allegro Breeze RV was introduced to dealers and news media at the annual Recreational Vehicle Industry Association's 47th Annual National RV Trade Show in Louisville, Kentucky, and was awarded “Best in Show”. At 28 feet, the Allegro Breeze RV is 17 feet shorter than Tiffin’s top-of-the-line Zephyr® RV, but only 9.5 feet longer than a typical full-size SUV. The Allegro Breeze GVWR is 21,500 lbs. The Allegro Breeze RV will begin appearing at Tiffin's network of dealerships in the U.S. and Canada in June 2010. Pricing has not yet been announced.

The MaxxForce 7 will be rear-mounted on Tiffin's own PowerGlide® chassis. Introduced in 2008, the PowerGlide chassis quickly became a popular option, offering one-stop service for Tiffin owners at dealerships and the Tiffin service facility. The PowerGlide chassis for the Allegro Breeze RV is newly designed on a coach-ready platform.

Tiffin Motorhomes received one of three prestigious Quality Circle Awards presented by the Recreational Vehicle Dealers Association to Class A motorhome manufacturers this year for design, reliability, quality, value and competitive price.
