The Jeep Grand Wagoneer is a premium American vehicle, making it the perfect vehicle to introduce the most anticipated new propulsion system from the Chrysler Group. Known internally as the “GME-T6” or the Tornado engine is a turbocharged 3.0-liter inline-six-cylinder that will make its world debut this month at the New York International Auto Show (NYIAS).
GME-T6 “Tornado” Engine Debuting In New York
According to Mopar Insiders, there will be three variants of the GME-T6 available for future Stellantis products. The first version that we will see will debut on the Wagoneer lineup next month at NYIAS and will be the High-Output variant (H.O.). While not much is known about the H.O. version, spy photos posted on Mopar Insiders show what’s suspected to be a Grand Wagonee with the GME-T6 H.O. engine features dual-exhaust, and will require Premium Unleaded fuel according to the decals above the fuel door. We hope that the fuel economy rating will be good enough to justify the purchase, considering how painful it’s getting to stop at a gas station.
The 3.0-liter GME-T6 H.O. inline-six-cylinder engine will be followed up by a plug-in hybrid model (PHEV) in 2023. The PHEV will likely run a similar system to the Grand Cherokee 4xe and will probably be a popular option as gas prices continue to rise. The ZF-sourced 8P75PH 8-speed automatic transmission will likely be fitted to the GME-T6 PHEV. The ZF unit features a motor generator rated at 134 horsepower and 181 lb-ft. of torque. Additionally, the PHEV variant could offer an electric-only mode that would propel the vehicle around without using any fuel, which could be helpful for short commutes.
The third and final variant for the GME-T6 engine will be a standard output (S.O.) which will be as you would expect. Just the engine without any fancy modifications to it. However, that doesn’t mean it’s not exciting, as the turbocharged Tornado inline-6’s primary impetus is two things: fuel economy standards and optics. We’re bound to see both of those things in one exciting package as this engine starts to roll out under the hood of Stellantis vehicles.
