Alfa Romeo Highlights 75 Years of All-Wheel Drive Development

Stellantis reports Alfa Romeo marking 75 years of AWD history, from the 1900M “Matta” to modern Giulia, Stelvio and Tonale models using Q4 technology. Explore the brand’s evolution.

Alfa Romeo is marking the 75th anniversary of its all-wheel-drive technology, highlighting a development path that stretches from early off-road vehicles of the 1950s to today’s Giulia, Stelvio and Tonale models. For the Italian brand, traction on all four wheels has never been just a technical experiment but a recurring theme that has evolved alongside its performance heritage.

The origins of this story go back even further, to experimental four-wheel-drive prototypes of the 1920s. The first production model to embody the concept was the Alfa Romeo 1900M “Matta”, introduced in 1951. Developed primarily for the Italian military, the vehicle was produced between 1952 and 1954 in AR51 and AR52 versions. Powered by a 1.9-liter four-cylinder engine producing about 65 horsepower and paired with a four-speed manual transmission and a transfer case with a low range, the Matta laid the groundwork for Alfa Romeo’s future AWD development.

The next major step came three decades later. In 1984 Alfa Romeo launched the Alfa 33 4x4, followed by the 33 Permanent 4 with a permanent all-wheel-drive system. These models introduced more advanced torque-distribution concepts and paved the way for the Q4 systems that would define Alfa Romeo’s AWD identity in the following years.

By the early 1990s the technology had entered a new phase. The Alfa Romeo Protéo concept of 1991 showcased permanent all-wheel drive combined with innovative engineering solutions. Around the same time, production cars such as the 33, 155 and 164 adopted the Q4 designation, establishing all-wheel drive as a strategic element of the brand’s model range.

One of the most prominent chapters in this history belongs to the Alfa Romeo 155. The road-going 155 Q4 featured a turbocharged two-liter engine and a drivetrain derived from the Lancia Delta Integrale. Its engineering foundations also supported Alfa Romeo’s return to top-level touring-car racing. In 1993 Nicola Larini secured the Deutsche Tourenwagen Masters title in the Alfa Romeo 155 V6 TI, winning ten races during the season and reinforcing the brand’s motorsport reputation.

Throughout the following decade the Q4 system expanded to additional models. In the 2000s it appeared in vehicles such as the 156 Crosswagon Q4, and later in the 159, Brera and Spider, confirming the role of all-wheel drive as an integral part of Alfa Romeo’s engineering philosophy.

Today AWD remains a key component of the brand’s strategy. The modern Alfa Romeo lineup offers the Q4 system across all current models, including the Giulia sedan and the Stelvio and Tonale SUVs. Under normal conditions the system preserves a rear-wheel-drive character, but it can quickly redistribute torque between the axles when additional traction is required.

In the United States, the 2026 Alfa Romeo Tonale features a 2.0-liter turbocharged engine delivering 268 horsepower and 295 lb-ft of torque, paired with a nine-speed automatic transmission and a standard Q4 all-wheel-drive system. The Giulia and Stelvio models use a turbocharged 2.0-liter engine producing 280 horsepower and 306 lb-ft of torque, combined with an eight-speed automatic transmission and an active transfer case designed to manage torque distribution.

The Q4 system constantly analyzes wheel speed, steering input and throttle position to adjust torque between the front and rear axles in real time. This approach allows Alfa Romeo to maintain the agile, performance-focused dynamics associated with the brand while adding stability and traction in challenging driving conditions.

In recent years the importance of this technology has continued to grow. According to the company, Q4 all-wheel-drive variants accounted for 26% of Alfa Romeo’s global sales in 2025, underlining the increasing relevance of all-weather capability within the brand’s overall strategy.

Seen in this context, Alfa Romeo’s 75-year history with all-wheel drive represents more than a series of technical milestones. It reflects the evolution of an engineering philosophy that links early off-road vehicles, championship-winning touring cars and modern performance models designed for everyday driving.
