RVIA Economic Impact Study

The Recreation Vehicle Industry Association commissioned an Economic Impact Study on the RV industry, released on June 7, 2016. The study found that the RV industry contributes about $49.7 billion in economic output or 0.28 percent of the Gross Domestic Product. Through its production and distribution linkages, the industry impacts firms in 426 of the 440 sectors of the United States economy.

Nationwide, the industry is responsible for 216,170 jobs, both directly and inderectly, creating an economic impact of $37.5 billion. The full study results, along with each individual state and congressional district's economic impact is available on the website by clicking here .

Cummins Inc. Unveils 2017 X15 and B6.7 Engines

Thu Dec 8, 2016

145322220422564.jpgCOLUMBUS, Indiana - Cummins Inc. unveiled the 2017 X15 and B6.7 engines at the Recreational Vehicle Industry Association National RV Trade Show in Louisville, Kentucky.

The new X15 platform carries forward the best-in-class attributes of the ISX15 with the implementation of an optimized compression ratio, air handling system and cam profile to increase both performance capability and fuel efficiency. The new B6.7 engine builds on a legacy of 30-plus years of continuous improvement and 12 million engines sold with further fuel economy and reliability improvements.

With up to 605 hp, the X15 Performance Series was designed for even better performance at lower rpm, faster acceleration and more confidence in the mountains. Peak torque of up to 1,950 pounds per foot is delivered across a wide engine rpm range, so less downshifting occurs and less fuel is used. Equally powerful is the engine braking, with up to 600 braking horsepower for added confidence on downhill grades. Ten percent additional braking power below 1,700 rpm helps reduce service brake wear and replacement costs.

The X15 Performance Series also features an optimized cam profile to minimize parasitic loss during combustion, in essence breathing easier, increasing thermal efficiency and fuel economy. The engine also features an industry leading compression ratio, the Cummins VGT Turbo and the XPI fuel system, to further improve engine acceleration and reduce fuel consumption. Additional engine efficiencies have also been realized by minimizing friction losses throughout the X15, including the water pump, gear train, lube system, piston and Exhaust Gas Recirculation system.

The big-bore advantage of the 15-liter platform allows the highest level of performance without compromising durability. Power cylinder improvements reduce oil consumption up to 40 percent and a new impactor breather eliminates crankcase breather element replacement. Servicing is also simplified with an oil pan redesign which moves to a single drain plug. Other improvements include a stronger turbo actuator, higher flow EGR cooler and removal of the hydrocarbon doser for reduced maintenance costs.

“Every component that was updated on the X15 was scrutinized from top to bottom, so that we weren’t just enhancing fuel economy or power – we were doing that while meeting or exceeding the highest standards of quality,” Cummins Executive Director Brett Merritt says.

The B6.7 has 50 percent more torque than gasoline engines and a standard VGT exhaust brake, all at lower rpm for less noise, making the engine stronger through the hills. With up to 40 percent better fuel economy than gasoline powered motorhomes, the B6.7 lets you choose where you stop for fuel and it lasts two to three times longer than gasoline engines while providing a quieter ride.

For 2017, customers with the B6.7 will see further performance enhancements and fuel economy improvement of up to 5 percent through improvements in the combustion recipe, lower friction components and air handling efficiency. A new heavy duty turbo bearing system and EGR system enhancements also were introduced for even greater reliability. Diagnostics were further improved resulting in fewer check engine lamps.

Both the X15 and B6.7 feature Cummins NanoNet fuel filters, which provide 10 times better protection than conventional fuel filters and Cummins Single Module aftertreatment, which has even better thermal efficiency with weight and space savings over the current multi-module design. This results in fewer regenerations and meets both OBD16 and GHG17 requirements.

Better Connected
Already well proven, Cummins Connected Diagnostics uses customer supplied telematics to wirelessly connect the engine to Cummins for rapid fault diagnosis. A diagnosis of the fault and clear recommendations regarding continued vehicle operation or the need for immediate service, are sent instantly either via e-mail or the new mobile app. It provides assurance by allowing a service intervention to be scheduled when it is most convenient or informs customers when immediate service is required. The power of Cummins information and services enabled by data can provide operational guidance via email in the rare instances when a check engine light occurs.

Unmatched Support
Starting with engines built for motorhomes in 2017, Cummins will offer 6-, 7-, and 8-year extended coverages for purchase on the B6.7, L9 and X15, for greater peace of mind beyond the standard 5-year, 100,000-mile warranty. All Cummins engines are backed by the largest and most capable support network in North America, with more than 3,500 authorized repair locations, including more than 40 CoachCare locations that specialize in RVs. Cummins Care, at 1-800-DIESELS (1-800-343-7357), is available 24/7/365 to locate the nearest available and authorized facility any time of day or night.

In addition to the traditional service network, Cummins provides a number of ways to stay directly connected to your engine. QuickServe Mobile is one more way to stay connected. Available for Android and Apple iPhone, this free app provides instant access to parts and service information, including engine build information, parts catalog, fault code analyzer and troubleshooting information. More enhancements are planned for 2017 to give customers and dealers even more ways to stay connected with the engine.

Cummins offers a complete range of diesel engines from 200 to 605 horsepower (194-447 kW). In addition, Cummins also offers a full range of generator sets from 3 to 15 kW for RV customers.
