Maserati entered a new era with the Biturbo in December 1981. Company owner Alejandro De Tomaso envisioned the sporty coupe as a means of increasing the brand’s reach with a new model offering top performance and a competitive price: a bold strategy for attracting new customers to Maserati. What is a biturbo engine? The Biturbo’s engine was a new and compact 90-degree V6 that featured induction via two small turbochargers—a world’s first on a production car. The Biturbo was a big success, thanks to its excellent performance and luxurious interior, although first-generation versions challenged the factory’s production capacity. In 1983, the more powerful Biturbo S featured twin intercoolers, distinguished by two NACA air ducts on the hood. In 1986 and 1987, both versions were upgraded with fuel injection as the Biturbo i and Biturbo Si.
