Coopersburg & Liberty Kenworth Announces T680 Kenworth Trucks to Get Even More Fuel-Efficient in 2017, with Cummins X15 Efficiency Engines

T680 Kenworth trucks are already well-known as the best option on the roads for fuel-efficient driving. In 2017, the best will get better, thanks to new Cummins X15 Efficiency engines.

Coopersburg, PA, January 05, 2017 --( With bodies designed by computer for maximum aerodynamics and superior computer monitoring, the T680 Kenworth trucks are being embraced by a wide range of fleets and independent owners for their ability to cut on-the-road costs. This makes them tailor-made for the Cummins X15 line, which is expected to be the most fuel-efficient heavy-duty engine on the market.

When it becomes widely available in early 2017, the Cummins X15 Efficiency engine will offer the best power-to-performance ratio on the market. The fuel-efficiency is further improved by several smart computer systems aimed at intelligent coasting and predictive cruise control in automated manual transmissions. Independent tests of the X15 in a T680 Kenworth truck with a 62,000lb load brought more than 9MPG, while still achieving performance up to 500HP and 1450-1850 lb-ft. of torque.

As one of the top dealers of Kenworth trucks in the Northeast, Coopersburg & Liberty Kenworth look forward to offering T680 Kenworth’s configured with these Cummins X15 Efficiency engines. This one-two combination of cost-cutting power will easily make the T680 an attractive buy across multiple markets, while still bringing the power necessary to haul heavy loads. (Those needing still more torque can consider the X15 Performance, which delivers up to 605HP, and 1650-2050 lb-ft. of torque.)

Those interested in the X15 are encouraged to contact Coopersburg & Liberty Kenworth to discuss reservations of these new 15-liter engines to ensure availability.
