you've been waiting for the next generation of the Maserati GranTurismo to come along before you place your order for a four-seat convertible, you'd better change your plans and act fast. Because the latest report coming in from across the pond confirms what we long suspected: that the next GranTurismo will be offered in coupe form only.

The news comes from Auto Express, which quotes Peter Denton – Maserati's manager for Northern Europe – as saying that "The GranTurismo will be replaced at the end of 2017, but as a coupe only." That coupe will also be smaller than the current model, but the timeframe means that by the time it's phased out, the current GT will have been on the market for a staggering ten years – based on architecture dating back to 2003, if not earlier.

That doesn't mean that Maserati won't offer a convertible altogether, though. By the time the new GranTurismo arrives, the Trident marque will have introduced the Alfieri, which (like the outgoing GranTurismo) will be offered as both a coupe and a convertible.

The trend seems to follow a larger industry direction away from four-seat convertibles – particularly under theFiat Chrysler Automobiles umbrella. Chrysler discontinued the 200 Convertible, and unlike Ford and Chevythat offer convertible versions of the Mustang and Camaro, Dodge does not offer a convertible Challenger. Aside from the fated GranTurismo Convertible (known as the GranCabrio overseas) and the Jeep Wrangler, the only droptop in the entire sprawling group with more than two seats is the Ferrari California – a model whose presence may have factored in to the decision to discontinue the Maser cabriolet as well.

The news will undoubtedly come as welcome to competitors like Aston Martin and Bentley, which between them offer several four-seat convertibles including the DB9 Volante, Vanquish Volante and Continental GTC. It remains to be seen, however, whether Jaguar will offer a convertible version of the next XK to stand alongside the smaller F-Type roadster.
