Background
When products become simply known by the inventor’s name, then it is usually a sign that things have gone well. Think of Laszlo Biro’s pen, William Henry Hoover’s vacuum cleaner and even Erno Rubik’s cube. As so it was with Giuseppe Busso’s engine.
Busso trained in industrial design and started his career with Fiat’s aviation department before joining Alfa Romeo in 1939. Busso’s role at Alfa Romeo essentially revolved around designing competition engines and his stock at the company wasn’t dented by a quick detour to Ferrari in 1946 as Technical Director. By 1948, however, he was back at Alfa and had taken charge mechanical engineering for Alfa Romeo road cars. This included taking part in the creation of the Alfa Romeo 1900, Giulietta, Giulia, 1750, 2000 and Alfetta. With the Giulietta, Busso introduced a legendary four-cylinder Alfa Romeo Twin Cam engine, also known as the “bialbero” or “Nord” engine.
By 1968, however, the prototype of a V6 engine was created that would ultimately go on to bear his name. The 60-degree V6 engine wouldn’t find a home in an Alfa Romeo, however, until the ill-fated Alfa 6 arrived. The 6 was announced in 1973 but wasn’t actually available until 1979 due to the rumbling fuel crisis, by which point it was hopelessly outdated. It is widely accepted that the 2,492cc V6 engine with a full six Dell’ Orto carbs and producing 156bhp was undeniably the best part of the Alfa 6. The Busso designed V6 got its big break, however, in the Alfetta GTV6 of 1980. Now housed in a sleeker, lighter more aerodynamic body, the V6 could show the world what it could do. Despite Alfa’s brochures claiming a top speed for the GTV6 of 127mph, contemporary tests had achieved over 140mph and 0-60mph in 8 seconds. Eye-catching numbers for 1980.
Other stunning applications followed but the V6 Busso enjoyed its swansong in the 147 and 156 GTA’s of 2002. It had been three decades since that hallowed three-letter-acronym had appeared on the GTA Junior of 1968 and a lot of mystique and kudos has grown around it. Lucky then that in the 2002 GTAs the Busso had been dialled up to 11 for its grand finale. Now up at 3,179cc it delivered 247bhp and 221 Ib-ft of torque. The final Busso V6 rolled off the Arese production line in 2006. In a remarkable twist, Giuseppe Busso passed away just three days later.
Shoehorning the 3.2L V6 into the nose of Alfa’s pretty small family car and Car of the Year for 2001 was an inspired idea. Busso’s unit lent the little car a 6-second 0-60mph time and a top speed in excess of 150mph and lent the driver an ear-to-ear perma-grin.
