by Sports car based on the legendary DTM hero Alfa Romeo
Today, the boxy Alfa Romeo 155 sedan is rarely remembered, except by motorsport fans who recall its triumphs in touring car championships in Italy, Spain, Great Britain, and Germany. Its most extreme DTM configuration inspired the creation of a modern interpretation of the 155 model, built on components of the current Quadrifoglio.
The car is named 55 SGT by the company SGT Automobili, which emphasizes that it is not a restomod. Instead, they seem to have created a machine that looks like the 1993 Alfa Romeo that won the DTM with the V6 TI engine, but under the carbon body hides a modern Giulia.
Powertrain
Under the hood is a twin-turbo 2.9-liter V6 engine paired with an eight-speed automatic transmission. The Stradale version produces up to 612 hp (620 PS) in its most powerful mode, while the Trofeo raises the bar to 740 hp (750 PS) and 800 Nm of torque. Like the original winning 155s, the 55 SGT has all-wheel drive. Drivers can adjust torque distribution or even activate a drift mode that sends all power to the rear axle.
According to SGT, the reinforced structure provides 25% greater torsional rigidity compared to the donor platform. Extensive use of carbon, Kevlar, and carbotitanium (a composite material invented by Pagani subsidiary) helps keep weight low.
Formula 1-level aerodynamics
The Stradale version weighs 1590 kg, while the more extreme Trofeo sheds another 100 kg, reaching 1490 kg. Other Trofeo advantages include carbon suspension arms, an integrated four-point jack for quick wheel changes on the track, improved brakes, and an aerodynamic package that generates up to 460 kg of downforce and features a DRS system like in Formula 1.
Interior and exclusivity
The cabin follows the same driver-oriented philosophy as the chassis. The rear seats are gone, replaced by a roll cage. Bucket seats, racing controls on a luxurious carbon console create a DTM atmosphere, but with much more luxury and refinement than a real race car or a modern Alfa Romeo.
Only 55 cars will be produced. The first 10 units make up the Opening Edition, intended for selected clients. Each car can be configured as a unique example.
Price and availability
SGT Automobili does not disclose the price, but it is known the conversion will cost around 500,000 euros ($570,000) on top of the donor Giulia Quadrifoglio. The company reported it has already received four orders, so only six of the ten Opening Edition slots remain.
This project demonstrates how modern technologies and materials can breathe new life into classic racing legends, offering not just restoration but a radical reinterpretation. The half-million euro price tag without the donor car positions the 55 SGT as an extremely exclusive product for collectors seeking a blend of Alfa Romeo’s historic heritage with 21st-century engineering. The limited run of 55 units and the possibility of individual customization make each car a unique work of art on wheels.
