Four years ago, the rumor mill suggested a brand-new engine for multiple brands under the Fiat Chrysler Automobiles umbrella. Currently owned by Stellantis, the peeps at FCA still haven’t confirmed or denied the hearsay.
“An unofficial but reliable source” told StellPower.com that a straight-six turbo will indeed happen for the all-new Challenger, which is expected to premiere in 2023 for the 2024 model year. Although unverified, the source may be onto something because the current-gen Challenger is due to leave us in 2023 along with the Charger and the 6.2-liter HEMI Hellcat family.
Dubbed T6, the largest member of the Global Medium Engine family could replace the 5.7-liter HEMI used by the outgoing Challenger, Charger, Durango, and Ram 1500. Rumored with 3.0 liters of displacement, which may be true given the modularity of the Global Medium Engine family, the all-new Tornado should come in a number of tunes depending on application.
It’s pretty safe to assume a minimum output of 100 horsepower per liter and, at the very top of the range, the 500-horsepower barrier is within the automaker’s reach with nothing more than more boost and a re-mapped engine control unit. Further expected with hybrid assistance, the straight-six engine may be connected to the fourth-generation ZF 8HP automatic.
Still an eight-speed transmission, just like the current 8HP, the newcomer incorporates an electric motor that puts out anything between 80 to 160 kW (107 to 215 horsepower). The motor is also capable of sustaining 450 Nm (332 pound-feet) on full song, which is a lot in combination with the internal combustion engine. Speaking of which, forced induction helps the Tornado develop peak torque lower in the rev range compared to the 5.7-liter V8.
Whatever the future may hold for the long-rumored sixer, there is no denying Fiat Chrysler needs more frugal powerplants in the near future. The latest CAFE standards would increase fuel efficiency by 8 percent annually for model years 2024 to 2026 and increase the estimated fleetwide average by 12 miles per gallon for model year 2026, relative to model year 2021.
