Jeep Grand Wagoneer gets stuffed with 707-HP Hellcat engine

Remember when we thought that with nearly 600 hp (450 kW) at the crank, the new Audi RS6 Avant packed way too much engine power for its class? Okay, forget it. This 1989 Jeep Grand Wagoneer will blow that one to bits at a drag strip, anyway.

Restored by Texas-based car tune-up service Сollins Bros Jeep, the 30-year-old wagon received the 6.4-liter supercharged V8 taken straight from the latest Dodge Charger SRT Hellcat. The mill comes factory-rated at 707 hp (527 kW) and 875 Nm (645 lb-ft) of torque. Interestingly, the Wagoneer’s own 5.9-liter V8 was hardly smaller, but at 144 hp (107 kW), nearly five times weaker.

The tuner mostly left the classical exterior of the wagon alone, given its good overall condition. The brakes and the exhaust system were replaced with performance-friendlier counterparts, and the entire cabin has been overhauled in a style that precisely matched the original. In fact, you will be challenged to notice the difference.

As of today, the Grand Wagoneer Hellwagon exists in a single copy, but Сollins Bros Jeep says it will gladly build a few more given enough demand.
