Default Jeep and RAM ready for life without HEMI V8


Jeep and RAM ready for life without HEMI V8

Long-running 5.7-litre HEMI V8 to finally bow out to more sophisticated inline six-cylinder
Stellantis is primed to finally pension off its third-generation HEMI family of V8s after 18 years in production following reports of an all-new turbocharged 'Tornado' inline six-cylinder surfaced on the car-making group's official website.
Initially posted on the Stellantis' powertrain blog Stellpower but now deleted, referenced the all-new '3.0-litre GME T6' inline-six cylinder and confirmed it would be assembled at Stellantis' Saltillo plant in Mexico.

No further details or specification were released but it's thought its arrival is imminent and it is expected to replace the 5.7-litre HEMI V8 as well as the much mightier 6.2-litre Hellcat and Demon versions, plus the latest 6.4-litre '392' derivative used in the latest V8-powered Jeep Wrangler.

Instead of dropping the V8 altogether, it's thought the new inline six-cylinder will be introduced gradually except in Europe, and possibly Australia, where Euro fleet average CO2 emissions will force the adoption of the new family of sixes far faster in right-hand drive models.

Confirmed to come with a 3.0-litre engine displacement, to meet ever-stricter emissions it's almost certain Jeep models will need to embrace electrification.

Plug-in hybrid versions are also expected to be offered with the new inline-sixes.
The first car Down Under likely to benefit from the all-new powertrain is expected to be the new fifth-gen Jeep Grand Cherokee, with the inline-six set to also replace the ageing 3.6-litre V6 Pentastar petrol engine It's already been confirmed Australians' will miss out on the V8 offered elsewhere.

Tracing its history back to the early 1950s, the HEMI V8 takes its name from a hemispherical cylinder head that was invented to provide an enhanced surface-to-volume area for a more efficient burn.

The most powerful supercharged 6.2-litre HEMI V8 produced up to an incredible 603kW and 972Nm of torque under the bonnet of the fearsome Dodge Challenger SRT Demon channelling all that might to its rear wheels.
