Called the Hurricane, the Stellantis group has unveiled its new 3.0-litre twin-turbocharged in-line straight-six engine that is said to deliver enhanced fuel economy while also producing more power.
Stellantis says the new Hurricane engine is designed to match the power outputs of V8 powertrains while also being up to 15% more efficient than larger engines. The Hurricane is available in two variants, Standard Output and High Output.
The Standard Output variant in its 3.0-litre twin-turbo format delivers 294 kW and 610 Nm of torque. It has been optimised for the best fuel economy including the use of cooled exhaust gas circulation. The High Output’s 3.0-litre has been massaged to churn out more than 368 kW and 780 Nm while maintaining notable fuel economy during heavy use, such as towing.
The new Hurricane engine features a deep-skirt cast-aluminium block with a structural aluminium alloy oil pan, cross-bolted steel main bearing caps that contain a strong rotating assembly of a forged steel crankshaft and forged steel connecting rods.
It is capable of maintaining at least 90% peak torque from 2 350 r/min all the way to its red line mark. Stellantis says specific power and torque ratings will differ based on vehicle.
Besides sharing its design features with the globally produced 2.0-litre turbocharged in-line four engine, the Hurricane also shares its bore, stroke and cylinder spacing.
The 3.0-litre Hurricane twin-turbo I-6 is produced at Stellantis’ Saltillo Engine Plant in Mexico and the first vehicles powered by the new unit are earmarked to go on sale this year.
