A new Italian performance car company has unveiled its first creation, transforming the modern Alfa Romeo Giulia Quadrifoglio into a road-going tribute to a touring car great.
The SGT Automobili 5S-SGT pays homage to the Alfa Romeo 155 V6 TI that dominated the 1993 DTM championship, combining retro-inspired styling with contemporary super saloon performance.
Rather than creating a replica or restoring an original 155, SGT Automobili says it has reimagined what the iconic racer could look like if it were designed and built today.
To achieve that vision, the company has replaced the Giulia Quadrifoglio’s bodywork with bespoke carbon-fibre panels that closely mirror the aggressive box-flared appearance of the championship-winning touring car while remaining fully road legal.
Underneath, however, it remains firmly rooted in modern Alfa Romeo engineering.
Power comes from the Giulia Quadrifoglio’s Ferrari-derived 2.9-litre twin-turbocharged V6, although SGT has significantly increased output over the standard model.
The entry-level Stradale version develops 457kW (612bhp), while the more extreme Trofeo specification lifts power to 552kW (740bhp). Both models receive a bespoke valved exhaust system that can remain relatively subdued for road driving before opening up to deliver a more aggressive soundtrack on track.
Drive is channeled via an upgraded version of Alfa Romeo’s eight-speed automatic transmission, while this 155 tribute runs an all-wheel drive set-up with a self-locking centre diff and rear LSD featuring torque vectoring. SGT says the transmission has been strengthened to cope with the additional performance, while drivers can also select a rear-wheel-drive mode that sends all available power to the rear axle.
The mechanical upgrades extend beyond the engine.
SGT claims the chassis is now 25 per cent stiffer torsionally than the standard Giulia Quadrifoglio thanks to carbon fibre reinforcing in key areas, promising sharper handling and greater precision under hard driving. It is fitted with electromagnetic dampers with three settings; soft, medium and hard while compression and rebound are adjustable too. The Stradale model features 360mm rotors upfront with six-piston Brembo calipers, while the Trofeo version gets 395mm discs.
Inside, the focus shifts firmly towards the circuit. The rear seats have been removed in favour of a roll cage and integrated fire extinguisher, while lightweight carbon-fibre bucket seats replace the standard front chairs.
A redesigned centre console houses dedicated controls allowing drivers to adjust the adaptive dampers, differential settings and engine calibration to suit road or track conditions.
Despite the extensive structural upgrades and added performance, weight has been kept in check. The Stradale tips the scales at a claimed 1590kg, while the more hardcore Trofeo sheds a further 100kg to weigh just 1490kg.
Pricing and production numbers have yet to be announced.
