• This Video Will Teach You Everything You Need to Know About Alfa Romeo’s Busso V-6 Engine

Is this the best sounding V-6 ever made?

Do a quick search on any Alfa Romeo-dedicated forum and you’ll read a lot of praise aimed at the Busso V-6 engine coming from Alfisti around the world. Words like glorious, ferocious, intimidating, and passionate are common ways of describing the 2.5-liter V-6 coined by Giuseppe Busso.

The Busso V-6 still has ramifications to this day

Although the Busso V-6 was discontinued in 2005, its presence under the hood of an Alfa Romeo can double or even triple the car’s value on the used market. But the story of the Busso V-6 goes back to 1979, when Alfa Romeo needed a new powerplant to motivate the likes of Alfetta and Alfa 6.

The solution came as a 2.5-liter (2,492 cubic centimeters), 60-degree V-6 that initially cranked out 160 horsepower.

In 1983, a downsized iteration of the Busso V-6 was offered in a 2.0-liter displacement (1,997 cubic centimeters) which produced 135 horsepower. Over time, the engine was upgraded with new technology, such as Alfa Romeo’s in-house electronic fuel injection system known as Controllo Elettronico Motore.

Come 1987, the Italian carmaker was also building 3.0-liter versions of the Busso V-6 that powered the likes of Alfa Romeo 73 America and Alfa Romeo 164. As time passed on, the 3.0-liter V-6 was tuned to produce 192 horsepower inside the 1994-1998 Type 916 Alfa Romeo Spider.

Oh, and here’s what the engined sounded like on the Alfa Romeo GTV6. Try not to fall in love.

Tudor’s first encounter with cars took place when he was only a child. Back then, his father brought home a Trabant 601 Kombi and a few years later, a Wartburg 353.

As time went on, he started seeing that in other cars as well, and his love for the automobile was born.  Read More
