Alfa Romeo Giulia and Stelvio 2026: engines, electronics and Quadrifoglio changes

© media.stellantis.com

Giulia and Stelvio are heading into another model year with almost unchanged hardware but updated electronics. Alfa Romeo has added software changes and a driver-monitoring camera integrated into the front pillar. The company directly links these updates to adapting the cars to current regulatory requirements.

Against that backdrop, the powertrain range changes very little. In Europe, the 2.2-liter turbodiesels remain: 160 hp with rear-wheel drive and 210 hp with Q4, both paired with an eight-speed automatic. In the UK and some other regions, the 280-hp 2.0 GME gasoline engine also remains available.

Quadrifoglio has also been updated without losing its defining feature: Giulia and Stelvio continue to use the 2.9-liter V6 Bi-Turbo rated at 520 hp. Giulia remains rear-wheel drive, while Stelvio uses Q4 all-wheel drive. Stelvio Quadrifoglio now gets 21-inch wheels as standard instead of the previous 20-inch set. That is especially notable because production of the current Giulia and Stelvio has been extended into 2027.

The smaller Junior changes more noticeably inside. The whole range gets new door panels with soft-touch materials, different seats and revised trim for the dashboard and center tunnel. Sprint adds navigation, adaptive cruise control, keyless access, a rear-view camera, front, rear and side parking sensors, wireless charging and blind-spot monitoring. New 19-inch wheels use 225/45 R19 tires, and Alfa Romeo specifically notes that the tread width has increased by 10 mm.

Junior still offers several powertrains: the 145-hp hybrid is available with front-wheel drive or Q4 all-wheel drive, the electric version makes 156 hp, and the Veloce produces 280 hp. Junior is now the brand's main volume model: in the first half of 2026 it became the best-selling Alfa Romeo and was already sold in 45 markets.

Tonale keeps an even more traditional combination: a 175-hp 1.5-liter hybrid, a 130-hp 1.6 diesel and a 270-hp Q4 plug-in hybrid. The main changes here concern trim levels, materials and personalization options.

Alfa Romeo is not presenting this update as a generational change. The more interesting point is that Giulia and Stelvio, whose architecture dates back to the middle of the previous decade, are being adapted to new requirements with electronics while remaining in production with diesel engines and a 520-hp V6. Their true next generation remains a separate question.
