Continuing the evolution of the Biturbo, the Maserati Racing was presented in December 1990, which received a restyled nose inspired by the Shamal. Mechanical advancements included a new Getrag gearbox and intelligent, active shock absorbers from Koni. Under its hood, the 24-valve version of the 2.0-liter twin-turbo V6 engine featured a number of modifications, including a new crankshaft, lighter connecting rods and a higher compression ratio. Together with modified turbochargers, the 160 mph Racing was the most powerful 2.0-liter production car in the world.
