The short answer
Based on available data, the Jaguar XF comes out ahead of the Alfa Romeo Giulia on fuel economy and power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Owners overwhelmingly praise the Giulia's exceptional handling, steering feel, and unique character, often calling it the best-driving sedan in its class. However, this enthusiasm is tempered by widespread frustration with high maintenance costs, a poor dealership experience (especially at shared CDJR locations), and persistent reliability concerns, particularly for early model years. The Quadrifoglio is celebrated as a thrilling performance car, but its reputation for issues and steep depreciation is a recurring theme.
Best version to buy
The Quadrifoglio (QV) is the most praised version for its performance and driving experience, but owners caution that early model years (2017-2019) are risky. The 2.0T Veloce/Ti Sport is well-regarded for daily driving, though some wish for a mid-range V6 option between the base and QV.

Overall
Mixed sentiment with a clear generational divide. The first-generation XF (X250, ~2008-2015) is widely praised for its elegant, understated styling, high-quality interior materials (polished walnut, leather, wool carpeting), and engaging, driver-friendly dynamics. The supercharged V8 (XF-R) and V6 petrol engines are particularly celebrated for their power and character.
Best version to buy
First-generation (pre-2016) models with the 5.0L supercharged V8 (XF-R) or the 3.0L supercharged V6 petrol engine are most recommended for performance and character. For the second generation, the 3.0L V6 petrol or diesel engines are advised over the smaller 2.0L Ingenium units.
