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

January 10, 2017

January 5, 2017[?] – Coopersburg, PA – 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.

Computers design the bodies for maximum aerodynamics and superior computer monitoring. The T680 Kenworth trucks are embraced, typically 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. The aim is to create the most economical and fuel-efficient heavy-duty engine available in the market.

When it becomes available in 2017, the Cummins X15 Efficiency engine will offer the best power-to-performance ratio on the market. Several smart computer systems further improve the fuel-efficiency. These are aimed at intelligent coasting and predictive cruise control in automated manual transmissions. Independent tests of the X15 in a T680 Kenworth truck are 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 looks forward to offering T680 Kenworth’s configured with Cummins X15 Efficiency engines. This one-two combination of cost-cutting power will easily make the T680 an attractive buy across multiple markets.  [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. With our team, you can discuss reservations for these new 15-liter engines to ensure availability.
