context_page_description: The Alfa Romeo V6 engine was a 60° V6 engine made by Alfa Romeo from 1979 to 2005. It was developed in the early 1970s by Giuseppe Busso, and used on the Alfa 6 with a displacement of 2.5 L and a SOHC 12-valve cylinder head. Later versions ranged from 1,997 to 3,195 cc and had DOHC 24-valve valvetrains. The original design had short pushrods for the exhaust valves in a design similar to earlier Lancia Fulvia engines. The first DOHC version was in the 1993 Alfa Romeo 164, with an aluminium alloy engine block and head with sodium filled exhaust valves.
  The Alfa Romeo V6 has been used in kit cars like the Ultima GTR, Hawk HF Series, and DAX, as well as the Gillet Vertigo sports car. In August 2011 EVO magazine wrote that "the original Alfa Romeo V6 was the most glorious-sounding six-cylinder road engine ever," while the British Classic & Sports Car magazine described it as "the best sounding engine this side of a Maserati V8." The Alfa Romeo V6 engine has also been used in ice resurfacer made by engo Ltd. in Italy.
context_section_description: The engine was upgraded to dual overhead cams and four valves per cylinder in 1993. Due to this and other refinements, this engine produced 211 PS (155 kW; 208 hp) for the regular 1993 Alfa Romeo 164, with 230 PS (169 kW; 227 hp) and 276 N⋅m (204 lbf⋅ft) in the 164 QV with its engine producing 232 PS (171 kW; 229 hp) on the Q4 model which in its final production run in 1996, it got reduced to 228 PS (168 kW; 225 hp) but with increased torque. The final run of 3.0 V6 engines in the GTV, Spider and 166 range, produced 218–220 PS (160–162 kW; 215–217 hp) in the Euro 3-compliant version. The engine has a bore and stroke of 93 mm × 72.6 mm (3.66 in × 2.86 in), the same as the two-valve.
