• SGT Automobili reimagines Alfa’s legendary 1990s DTM hero.
  • Twin-turbo 2.9-liter V6 sends up to 740 hp to all four wheels.
  • Just 55 planned, buyers choose Stradale or lighter Trofeo spec.

Alfa Romeo’s boxy 155 sedan is barely remembered these days, bar motorsport fans who recall how it scooped up touring car championships in Italy, Spain, the UK and Germany. Now its wildest DTM configuration is used as the inspiration for a reimagined 155 built around modern Quadrifoglio components.

The car is the 55 SGT from SGT Automobili, which stresses that its car is not a restomod. Instead, it seems to have built something that looks like Alfa’s 1993 DTM-winning V6 TI, but is really a current-shape Giulia under its carbon skin.

The Powertrain

Power comes from a twin-turbocharged 2.9-liter V6 paired with an eight-speed automatic transmission. The Stradale produces up to 612 hp (620 PS) in its hottest setting, while the Trofeo raises the stakes to 740 hp (750 PS) and 590 lb-ft (800 Nm). Like the original race-winning 155s, the 55 SGT is all-wheel drive, and drivers can also adjust torque distribution, or even switch into a drift mode that sends everything rearward.

SGT says the reinforced structure delivers 25 percent greater torsional rigidity than its donor platform, while extensive use of carbon fiber, Kevlar, and carbotitanium, a composite material invented by Pagani’s sister company, helps keep weight in check.

F1-Style Aero

The Stradale tips the scales at 1,590 kg (3,505 lbs), while the more hardcore Trofeo sheds another 100 kg for a claimed 1,490 kg (3,285 lbs) curb weight. Other reasons to go for the Trofeo include the carbon fiber wishbones, integral four-wheel lift kit for those speedy trackday tire swaps, uprated brakes and an aero package that delivers up to 460 kg (1,014 lbs) of downforce and includes an F1-style DRS system.

The cabin follows the same driver-focused philosophy as the chassis. Rear seats disappear in favor of a roll bar, while bucket seats, race inspired switchgear mounted in a gorgeous carbon console give a DTM feel, but with way more luxury and sophistication than you get in any real racer – or modern Alfa Romeo.

Only 55 cars will be built, the first 10 examples form an Opening Edition reserved for selected customers, while every car can be tailored as a genuine one-off.

Price And Availability

SGT Automobili doesn’t list a price, but we’ve learned that the conversion will cost around €500,000 ($570,000) in addition to a donor Giulia Quadrifoglio. The company told us they have already secured four orders, meaning that only six slots of the Opening Edition remain available.
