Next year, Maserati developed the car into a more road-friendly version, A6G/54. Wheelbase was stretched to 2550 mm to give more interior space, along with (relatively) luxury interior. 60 chassis were built, and again, they were bodied by various coachbuilders in coupe and spider form. Most remarkable of them was the 20 units of coupe built by Zagato. Zagato once again applied its light-alloy know-how to build an all-aluminum body, keeping the whole car light at 840kg. For better road use, Maserati detuned the straight-six to (a still remarkable) 150hp. Top speed dropped to 130mph. The Zagato model was used extensively in motor racing and usually won its category. Nevertheless, the world rarely remember those not competing at the top league, so its fame did not match Ferrari 250GT SWB, or to lesser extent Aston Martin DB4GT Zagato.
