Alfa Romeo 155 V6 TI (DTM)
The 155 V6 TI was Alfa Corse's Class 1 DTM weapon: a carbon-rich, four-wheel-drive silhouette racer whose 2.5-litre V6 screamed toward 12,000 rpm and won the 1993 DTM title at its first attempt.
History
When DTM adopted the liberal Class 1 rules for 1993, Alfa Romeo committed with Italian totality. The 155 V6 TI shared little with the road 155 beyond its shadow: a 60-degree V6 designed for extreme revs, permanent four-wheel drive with electronically managed torque split, a six-speed sequential box, and season-by-season aerodynamic development that gave a touring car genuine wings-and-diffuser downforce.
Nicola Larini won twelve races in 1993 to take the title against Mercedes — a debut campaign still ranked among touring car racing's greatest — and the war escalated from there: by the 1995–96 ITC seasons the cars carried telemetry, active differentials and around 490 hp at 11,900 rpm, running budgets that ultimately collapsed the category when Alfa and Opel withdrew after 1996.
Surviving V6 TIs live mostly with Alfa Romeo's Museo Storico and a handful of serious collectors; the handful in private hands headline DTM Classic demonstrations, where the V6's 12,000 rpm wail is routinely voted the event's soundtrack. As emblem of Italy's last works assault on German touring car racing, the 155 V6 TI carries cultural weight far beyond its production count.
Palmarès
DTM champion 1993 (Larini, 12 wins from the season); race wins every season 1993–96 across DTM and ITC including Mugello, Hockenheim and international rounds; the parallel 155 TS's 1994 BTCC-adjacent Silverstone win and 1992 Italian Superturismo title complete the family's record.
What to check before you buy
These are effectively prototypes: running one requires Alfa Corse-literate specialists (a small circle in Italy), spares are made-to-order, and V6 rebuilds price like historic F1 work. Verify chassis identity against Alfa Corse records and period entry lists — evolution stages (1993 vs 1995 vs ITC 1996 spec) differ enormously in complexity and support burden, with the earlier cars far more usable. Value the car on documented originality and event access (DTM Classic entry is the point of ownership) rather than any pretense of practical racing.
Did you know
- The 1996 ITC cars ran shift strategies and telemetry so advanced that F1 teams reportedly studied them — a touring car with satellite data in 1996.
- Larini's 1993 title made Alfa the first non-German champion of the modern DTM — Mercedes' response budget the following year reportedly tripled.
- The V6's exhaust note is so beloved that Alfa's museum fires the car on its rooftop track for anniversaries — the event announcements mention the engine before the car.
