( http://www.TFLcar.com ) If you thought that the only way to purchase a Jeep Wrangler was with a V6...you'd be wrong. In this preview video Nathan and Roman test a SRT Jeep Wrangler. They test a Jeep Wrangler with the 470 HP SRT 6.4L HEMI engine up one of the steepest Jeep trails on the TFLcar test turf. That's right the same engine that's in the SRT Jeep Grand Cherokee and Challenger transplanted into the Wrangler.
