International LT Launched Loudly, Described Enthusiastically

Popularity of Cummins ISX15 in ProStars led Navistar to choose the X15-powered LT625 as its initially introduced model. Cummins engines will be offered "as long as customers want them," a marketing exec said.

Navistar unveiled its new International LT series in Las Vegas on Sept. 30 with speeches, videos, hard rock music, and fire-and-smoke effects – a launch befitting a "Vegas" production and a vehicle range that will become the company’s flagship model and, executives hope, the most popular highway tractor on the market.
