Ferrari 166: the first Ferraris — from racing MM to Inter
The Ferrari 166 — the V12 model line that began in 1948, featuring both race cars (S, SC, MM) and the first road-going Ferraris (Inter). We look at the versions, engine, and what you need to know when buying such a special classic car.
Ferrari 166 in brief
The '166' denotes the displacement per cylinder — around 166 cm³. The range uses a 2.0-litre V12 engine. The racing versions debuted in 1948, with the road-going Inter following in 1949.
By 1949–1950, these cars had already secured victories in the Mille Miglia and Le Mans races. Today, the 166 is one of the most prized chapters in Ferrari's history.
Versions — what sets them apart
The 166 MM is the racing version, named after the Mille Miglia. Its most famous bodies are the Touring 'Barchetta'. The 166 S and SC were also built for the track.
The 166 Inter is the road-going version with coupé and cabriolet bodies, crafted by Italian coachbuilders, so each example can differ. Don't confuse it with the later Dino 166 P and 166 F2 — they had a 1.6-litre V6 engine.
Engine and tech
The engine is a Colombo-designed 2.0-litre V12, with power outputs varying by version. The racing cars were more potent than the Inter.
This is early Ferrari tech, so don't expect modern comforts — it's a collector's item and a historic rally car.
What to check when buying a Ferrari 166
Most importantly, due to the very low numbers — provenance, chassis and engine numbers, and racing history. Request all documents and expert certification, especially for originality.
Many 166 cars were modified, restored, or rebuilt, so carefully check if the body, engine, and chassis match each other.
Before buying, consult with a classic Ferrari specialist and participate only in trusted transactions.
