V8 engines are usually associated with size, weight, and excess. For decades, the idea of a V8 meant large displacement, deep exhaust notes, and engines designed to dominate through brute force.
Yet throughout automotive history, a few manufacturers went in the opposite direction. They built V8 engines that were surprisingly small.
These compact V8s were not created by accident. Some were born out of racing regulations, others from taxation laws, fuel economy pressures, or engineering curiosity. In many cases, manufacturers wanted the smoothness and character of a V8 without the penalties of large displacement.
Small V8 engines offered unique advantages. They delivered refined power delivery, high revving capability, and compact packaging that allowed them to fit into lighter or more balanced vehicles.
While they often sacrificed outright torque, they compensated with responsiveness and mechanical sophistication.
This list focuses on the smallest V8 engines ever used in production cars. Ranking is based primarily on displacement, not power output. Some of these engines powered exotic sports cars, while others appeared in unexpected everyday vehicles.
What makes these engines fascinating is how they challenged conventional thinking. They proved that a V8 did not need massive cubic inches to be special. Engineering creativity played a bigger role than raw size.
Each car on this list represents a unique moment in automotive history. Some were commercial successes, others were niche experiments. All of them demonstrated that the V8 layout could be adapted to fit remarkably small packages.
The cars are presented from smallest to progressively larger V8 engines. Each entry examines why the engine existed, how it functioned, and its significance.
Let us begin with the smallest production V8 engine ever installed in a road going car.

1. Ferrari 208 GTB and GTS
The Ferrari 208 GTB and GTS hold a unique place in automotive history. They are widely recognised as the smallest-displacement V8-powered production cars ever sold.
Built specifically for the Italian market, they represented an unusual response to government regulations rather than performance demands.
At the heart of the Ferrari 208 sat a 2.0 liter V8 engine. This displacement was chosen to fall under Italy’s heavy tax penalties applied to engines larger than two liters.
Ferrari engineers were tasked with creating a compliant car without abandoning the brand’s V8 identity.
The result was an incredibly compact V8 engine that prioritized high revs over torque. While output was modest compared to other Ferraris of the era, the engine retained the smoothness and balance that define a V8 layout.
Acceleration was not brutal, but it was engaging. The engine needed to be revved hard to extract performance, encouraging drivers to stay in the upper reaches of the tachometer. This created a very different driving experience from larger Ferrari V8s.
The engine’s compact size allowed the car to remain well balanced. Weight distribution was favorable, and handling felt nimble and predictable. The lighter engine improved turn in and overall responsiveness.
Sound played a key role in the appeal. Despite its small size, the V8 produced a sharp and exotic exhaust note. It sounded unmistakably Italian, even if it lacked the thunder of larger engines.
Later turbocharged versions improved performance significantly. Forced induction helped compensate for the lack of displacement while maintaining tax advantages. These versions became more usable and enjoyable on the road.
The interior and styling were identical to larger displacement Ferrari models. This meant buyers received the full Ferrari experience, minus the extreme performance and tax burden.
What makes the Ferrari 208 remarkable is not speed, but ingenuity. Ferrari managed to preserve brand identity under strict limitations. Few manufacturers would attempt such a solution.
Today, the 208 GTB and GTS are appreciated for their rarity and engineering creativity. They represent a moment when regulation shaped innovation rather than killing it.
As the smallest V8 production car ever built, the Ferrari 208 stands alone. It proves that even the most performance driven brands can adapt when forced to think differently.
