Whenever we talk about performance sedans, the BMW M3 and BMW M5, along with Mercedes-AMG's C63 and E63, are typically considered the segment standard. In recent years, we've seen a decline in the number of performance sedans available.One of the performance sedans we lost here in the US was also one of the most underrated performance sedans of the modern age, the Alfa Romeo Giulia Quadrifoglio. That gorgeous Italian sedan not only has enough grunt to contend with Germany's finest but can also be found on the used market for less than its closest rivals. The Giulia Was Alfa Romeo's Return To Form Alfa Romeo Alfa Romeo struggled in the late 1990s, and its problems persisted as the brand entered the new millennium. However, Alfa Romeo experienced some reprieve when the Alfa Romeo 156 debuted in the late 1990s. It became a sales success and was succeeded by the Alfa Romeo 159. The 159 served as Alfa Romeo's sporty four-door offering in its catalog until 2007.Although it lacked the iconic Busso V6 the world came to know and love, the Alfa Romeo 159 offered commendable performance in its highest-ranking trim levels. After the Alfa Romeo 159 was laid to rest in 2011, it would be roughly four years before we were introduced to its successor, the Alfa Romeo Giulia.The Giulia was a clean-sheet design, meant to bring the company back to its roots and designed by the same people who helped build models like the Ferrari 458 Speciale, which is worth its weight in gold today.Alfa Romeo The result of roughly two-and-a-half years of work was a rear-wheel-drive, sporty saloon with impressive performance, thanks to a sublime chassis, powertrain, and steering system, though hindered somewhat by less-than-ideal interior quality. However, the most tantalizing form of the Giulia, like its predecessor, was the Quadrifoglio model. How It Compares To Europe's Finest StellantisThe Giulia Quadrifoglio is one of the best performance sedans you could buy when new, and that remains true today in the used market. As the most performance-focused and athletic incarnation of the Giulia, its features and design are meant to improve its performance. The lightweight Italian relies on an aluminum chassis that not only offered the best torsional rigidity in its class at the time, but also achieves a 50/50 weight distribution between the two axles. That lightweight chassis is shrouded by several pieces of carbon fiber from the hood and roof.Alfa Romeo In pursuit of lower curb weight, the engine, braking system, and suspension were made from aluminum to keep their weight down, while even the propeller shaft was made from carbon fiber to keep its weight down to 3,840 lbs, only slightly heavier than its closest rivals. However, while heavier than the BMW M3, the Quadrifoglio benefits from its suspension, with the rear axle supported by a multi-link setup that balances performance, driving comfort, and subtlety, while the front axle is supported by a double wishbone system with a semi-virtual steering axis to improve filtering.In contrast, its rivals rely on strut suspension at the front and multi-link suspension at the rear.However, while its driving dynamics – the result of a commendable chassis balance – were a defining feature of the Quadrifoglio, the centerpiece of the Quadrifoglio was its twin-turbocharged V6. Although having less displacement than the powerplants used in the BMW F80 M3 and W205 C63 S, the Quadrifoglio's 2.9-liter V6 and the pair of turbochargers housed between the cylinder heads managed to produce more power, though the C63 S benefits from greater torque.Alfa Romeo Still, from a standstill, the Giulia Quadrifoglio is quicker to 60 mph and has a higher top speed. While fuel economy isn't at the forefront of any performance sedan's list of things to excel at, the V6 offers near-identical fuel economy to the BMW F80 M3 with the Competition package and the W205 Mercedes-AMG C63 S sedan.Another similarity between the three is interior dimensions, with all three nearly identical in headroom, legroom, and seating capacity. As far as performance sedans are concerned, the Giulia Quadrifoglio ticks nearly every box, and today, it can be had for a bargain on the used market. What It's Worth Today Alfa RomeoWhen the Giulia Quadrifoglio debuted, it had an MSRP of $72,000, while the standard Giulia had an MSRP of $37,995. At the time, this was on par with the BMW M3 and the Mercedes-AMG C63 S, but today it's nowhere near what you'd pay for one on the used market.Stellantis According to the data available on the CarBuzz Marketplace, the average value of the Giulia Quadrifoglio is approximately $42,735, while the average selling price is slightly lower at $39,545. Both values are lower than those of the BMW F80 M3 and the W205 Mercedes-AMG C63 S sedan on Classic.com.Based on the examples of the Giulia Quadrifoglio listed for sale at the time of writing this article, the average value for the examples listed ranges between $40,000 and $55,000. At the highest end of the pricing spectrum are, unsurprisingly, newer-model-year options with fewer than 10,000 miles, listed for over $70,000.In contrast, the most affordable examples of this Italian performance sedan are listed for as little as $26,995, with those sold in the last year priced even lower. It is entirely possible to find a well-maintained example for less than $50,000. Before The Next One Arrives Alfa Romeo Although we're singing the Giulia Quadrifoglio's praise now and despite there being merit to calling it underrated, that wasn't enough to stop Stellantis from removing the Giulia from its lineup. However, while that put a damper on Alfa Romeo's customer base in the US, thankfully, we're getting the Alfa Romeo Giulia Quadrifoglio back, kind of.At the start of 2026, Alfa unveiled the latest iteration of the vehicle called the Alfa Romeo Giulia Quadrifoglio Luna Rossa. Only 10 examples are planned for production, and each will benefit from the new low-drag aerodynamic package offered on the Luna Rossa model, which produces up to five times the downforce of the standard Giulia Quadrifoglio.Michal Okonski/CarBuzz/Valnet Alongside the aerodynamic improvements, there is a slight revision to the interior elements and a bump in power from 505 to 520 hp. However, while a new iteration of the Giulia Quadrifoglio is welcomed, we've got our sights set on the next generation of the Giulia.
