Unlike anything on road today

WESTERN Star have launched the 5700XE in Las Vegas and they're saying it's their most advanced fuel saver.

This north American truck is not available in Australia and so far there are no plans to bring it here - however at Big Rigs, we thought you would like a look at the new styling and give us your thoughts.

Western Star general manager Michael Jackon said the name XE stood for extreme efficiency and summarised exactly what the new truck was all about.

"By blending legendary Western Star ruggedness together with aerodynamic innovations, and the most fuel-efficient powertrain available, we have built a powerful solution that is the best of both worlds - and unlike anything else on the road today," he said.

The 5700XE features a 126-inch bumper to back of cab length with a set-back axle, and is available in a range of spacious and lightweight sleeper configurations.

All-new features such as an aerodynamic hood, roof, chassis and cab fairings reduce drag and increase efficiency.

Additional performance features include:


A new sweptback four-piece bumper with an under-bumper valance that contributes to aerodynamic efficiency.

New halogen headlights that are optimised for aerodynamic performance and excellent visibility.

A state-of-the-art visor specifically engineered to work with the impressive slope in the hood's rear air ramp to direct airflow over the cab without an aerodynamic penalty.

Roof and cab fairings that sweep back for tighter trailer gap and help direct air flow over and around the trailer.

Optional chassis side fairings that reduce drag by up to 6% while still providing easy access to batteries and DEF tank.

The Western Star Twin Force dual air intake, which feeds a massive centrally mounted air filter to improve efficiency.

Hand built at the award-winning DTNA Cleveland (N.C.) truck manufacturing plant, the 5700XE has premium style and comfort features.

Full production will begin in 2015.
