It wasn’t until 1972 that a 4.9 liter version of Maserati’s wet sump 90° V8 eventually found its way under the hood of the four-seater Indy grand tourer. The most powerful version of the Indy boasted 320 hp which pushed its top speed to 265 kph (165 mph). Power steering became standard on this version, as did the air conditioning system. Customers could choose between two different settings for the gearbox, with the shorter geared version intended for maximum usability in traffic.

Overall, the Indy’s tempting looks and efficient package in terms of comfort, performance and aerodynamics attracted 1,104 customers, including Roy Disney, gentleman driver/journalist Giovanni Lurani and German soccer ace Paul Breitner. Just 300 cars were sold with the new 4.9 engine, of which the last 200 received a new hydraulic brake system courtesy of parent company Citroën.
