Alfa Romeo Giulia and Stelvio Redesign Delayed to 2028 with New Powertrains, Including 550 HP Inline-Six Engine

Alfa Romeo has announced a significant delay for the redesigned Giulia and Stelvio, pushing their launch to 2028. The decision follows concerns over lackluster demand for electric vehicles among other automakers, prompting the brand to adopt a more cautious approach.

The new models will be built on the STLA Large platform, which also underpins the Dodge Challenger and supports both internal combustion engine (ICE) and electric powertrains. However, the transition has required extensive reengineering, particularly to enhance cooling for combustion powertrains.

Key Design Changes

The redesign includes several notable updates to both the Giulia sedan and Stelvio crossover:

• New fascias and functional grille for improved airflow and cooling.
• Slender headlights and a small V-shaped grille, as seen in patent images of the Stelvio.
• Sizable intakes on the Stelvio, though they appear to be largely blocked off for aerodynamic efficiency.
• Streamlined bodywork, pronounced wheel arches, plastic body cladding, and a rounded roof.
• Angular rear window, large rear spoiler, and distinctive taillight area on the Stelvio.

Powertrain Options: A Range for Every Driver

The Giulia and Stelvio will offer a diverse lineup of powertrains to cater to different preferences:

• Turbocharged four-cylinder engines with mild-hybrid technology as the base option.
• Twin-turbo 3.0-liter inline-six engine, sourced from the Dodge Charger Scat Pack, producing 550 hp (410 kW / 558 PS).
• Plug-in hybrid (PHEV) options, with details still scarce but expected to align with other Stellantis models.
• Fully electric variants, leveraging the STLA Large platform’s capability to accommodate 101-118 kWh battery packs and electric motors ranging from 168 hp (125 kW / 170 PS) to 443 hp (330 kW / 449 PS).

Earlier reports suggested that high-performance Quadrifoglio variants could feature a tri-motor powertrain producing over 1,000 hp (746 kW / 1,014 PS). However, Autocar has dismissed this idea, stating that no Stellantis model currently produces that much power. For context, the Maserati GranTurismo Folgore features a tri-motor setup with 751 hp (560 kW / 761 PS) and 995 lb-ft (1,348 Nm) of torque, enabling a 0-60 mph (0-96 km/h) sprint in 2.6 seconds and a top speed of 202 mph (325 km/h).

Alfa Romeo’s Strategic Shift

Alfa Romeo’s decision to delay the launch reflects a broader strategy to ensure the new Giulia and Stelvio meet market demands without compromising performance or reliability. CEO Santo Ficili emphasized the importance of a holistic approach, stating:

“We need to consider the entire world.”

This sentiment underscores the brand’s commitment to delivering vehicles that align with evolving consumer preferences while maintaining the performance and driving dynamics Alfa Romeo is known for.

As the automotive industry continues to transition toward electrification, Alfa Romeo’s cautious yet innovative approach positions the Giulia and Stelvio as versatile options for drivers seeking a blend of tradition and modernity.
