With the impending end of production for the popular supercharged 6.2-liter HEMI® HELLCAT V8 engine, Ram enthusiasts have been eagerly speculating about the future of the Ram 1500 TRX performance off-roader. Ram CEO, Mike Koval Jr., has hinted at the possibility of electrification as an alternative powertrain for the TRX.
However, given the mixed emotions surrounding battery-electric vehicles (BEVs) in North America, Ram engineers are currently testing a variant of the new twin-turbocharged 3.0-liter Hurricane6 inline-six-cylinder engine as a potential option for the next-generation TRX.
According to sources close to MoparInsiders.com, Ram engineers are actively running several Ram 1500 TRXs equipped with the high-output (H.O.) variant of the twin-turbocharged 3.0-liter Hurricane6 engine. The H.O. variant of the Hurricane6 offers enhanced performance characteristics and notable features:
- Twin Garrett turbochargers with liquid charge-air cooling for peak boost pressure of 26 psi.
- Lightweight, oil-jet-cooled, forged aluminum pistons with a diamond-like coating (DLC) on the pins to reduce friction.
- 9.5:1 compression ratio, recommending the use of premium fuel.
- Dual high-pressure direct fuel injection system with centrally mounted injectors in the cylinder head combustion chamber.
- Engine-mounted water-to-air charge cooler with a dedicated cooling circuit and dual inlet.
- Dual overhead camshafts with fully independent variable valve timing.
- Dual water-cooled exhaust manifolds are integrated into the cylinder head.
- Plasma Transfer Wire Arc (PTWA) coating in the cylinder bores for a low-friction wear surface.
The H.O. variant of the Hurricane6 engine can easily generate around 550 horsepower and over 500 lb.-ft. of torque. The engine is expected to be paired with an 8-speed automatic transmission from ZF to ensure efficient power delivery, similar to the current TRX and Grand Wagoneer models.
