Launched with hoopla amidst the recent Chicago Auto Show, the decidedly unique LoneStar from International Truck & Engine is being touted as a “game-changer”. The company talks about the new highway tractor bridging “the gap between workstyle and lifestyle,” calling its bold design “advanced classic”.

The distinctive grille and sloped hood are said to be inspired by International’s D-Series trucks of the 1940s and early 50s.

The truckmaker also says the LoneStar sets a higher standard for comfort through improved ergonomics, advanced electronics, and a quiet cab. It’s claimed to be 5 to 15% more fuel efficient than classic trucks.

Optional features include roll stability; traction control; Bluetooth integration for hands-free phone use; automotive-style dash and gauges with rosewood or titanium trim; and a 50-degree wheel cut. ABS is standard.

On the inside, the LoneStar offers a level of comfort and functionality typically found in recreational vehicles, says International. Highlights include: wood flooring in the sleeper; sofa-bed design with back pillows; swivel chairs; closed “airline” cabinets for maximum storage; stereo system with 11 speakers, sub-woofer and amplifier; pull-down bed with 42-in. premium mattress; and a desk-like workspace with plugs for laptop computers and the like.

The truck is available in both day cab and sleeper trim, with BBC dimensions of 132 and 196 in. respectively. There’s a choice of a Cummins ISX engine to 600 hp or a Caterpillar C15 up to 550 hp. Ratings for both start at 435 hp. The base transmission is an Eaton Fuller 10-speed manual, other options being the same as with the ProStar. Tandem rear axles up to 46,000 are available, from either ArvinMeritor or Dana. Meritor 40,000-pounders are standard.

The LoneStar will be available for order beginning in April 2008. It will be produced at Navistar’s plant in Chatham, Ont.
