Repower Profile: Cummins Jeep Wrangler

First in the line-up of “Repower Profiles” is our own Jeep Wrangler (TJ). This Wrangler started life as an ordinary Jeep, but with help of dedicated Cummins engineers and Axis Industries, it was the first test vehicle to have an R2.8 Turbo Diesel under the hood.
