In 1993, Alfa Romeo built the fabulous 155 V6 TI that dominated the DTM season and changed the course of the competition
In the 1990s, when the German Touring Car Championship (DTM) was dominated by local brands, an Italian sedan with angular lines crossed borders and changed the balance of forces on the track. The Alfa Romeo 155 V6 TI became one of the most iconic touring cars of the decade, remembered to this day as the model that challenged and defeated Mercedes and Opel on its own turf.

The story began in 1993, when Alfa Romeo decided to officially enter the Deutsche Tourenwagen Meisterschaft, the DTM. The championship was going through a phase of great technical sophistication with the regulations of the so-called Class 1, which allowed extremely advanced cars. Although they maintained the silhouette of production sedans, these models used tubular structures and bodies in composite materials, functioning in practice as competition prototypes.
To face rivals such as the Mercedes-Benz 190E and the Opel Calibra, Alfa Corse developed the 155 V6 TI from the sedan presented at the beginning of the decade. Despite the appearance similar to the street model, the race car was radically different. The engine was a 2.5-liter naturally aspirated V6 that in the last evolutions reached about 490 hp at almost 12 thousand rpm. Power was sent to all four wheels via an all-wheel drive system and a six-speed sequential gearbox.
Weighing close to 1,060 kilograms, the Italian sedan delivered performance worthy of a prototype. Acceleration from 0 to 100 km/h happened in about 2.5 seconds and the top speed exceeded 300 km/h, impressive numbers for a car visually based on a family sedan.
The impact on the tracks was immediate. Right at the opening of the 1993 season, in Zolder, the Alfa won both races of the weekend. By the end of the championship, Italian driver Nicola Larini had taken 11 wins in 22 races, securing the drivers’ and constructors’ titles for Alfa Romeo. It was a hard blow to the German brands, which had not seen a “gringo” dominate the season since the Volvo 240 “Flying Brick” indoctrinated in 1985.
Like any self-respecting Italian car, it takes an extra dose of folklore. The 155 V6 TI originally featured upturned exhausts. Among the numerous theories, there was one that said that the hot air expelled upwards had an aerodynamic function. But in fact, the flattened fold served to reduce the resonance that denounced adjustments outside the regulations.
This is because the regulation imposed a limit of 98 decibels of noise. To reduce excessive noise, it was necessary to install catalysts and dampers. But this would impact the power of the V6. Thus, pointed upwards, the noise went unnoticed. But the Germans found out.
In the following years, the 155 V6 TI continued to evolve. Engineering became increasingly sophisticated, with highly adjustable suspensions, refined aerodynamics, and electronic systems such as traction control and ABS brakes, rare solutions in touring cars of the time. The engine also received updates that allowed for higher and higher revs, accompanied by a metallic sound that became the car’s trademark.
The technological escalation, however, has brought a problem: costs. Class 1 cars were among the most advanced in world motorsport, and teams needed to invest more and more amounts to keep up with technical evolution. By the middle of the decade, the DTM was transformed into the International Touring Car Championship, but rising expenses made the championship untenable.
With the end of the category after the 1996 season and profound changes in the regulations of the touring car championships, complex machines such as the Alfa Romeo 155 V6 TI disappeared from the tracks. The new DTM that would emerge years later would adopt very different cars, with a more controlled technical philosophy.
Even with a relatively short career, the Italian sedan left a lasting mark on motorsport. Its dominance in 1993, sophisticated engineering and the sound of the V6 revving close to 12 thousand revolutions turned the model into one of the most remembered touring cars of the 1990s. For many fans, it represents an era in which touring car championships reached an extreme technological level and in which an Alfa Romeo managed to challenge the Germans at home and win.
