Maserati Quattroporte V (2003) & UCS F136S 4,244 cc DOHC 32v V8 Engine
The fifth generation of the Quattroporte (Tipo M139) was unveiled to the world at the Frankfurt Motor Show on 9 September 2003 and made its U.S. première at the 2003 Pebble Beach Concours d'Elegance; production started in 2003. Exterior and interior design was penned by Pininfarina's then chief designer Ken Okuyama.
Built on an entirely new platform named the M139, it was 50 cm (19.7 in) longer than its predecessor and sat on a 40 cm (15.7 in) longer wheelbase. The same architecture would later underpin the GranTurismo and GranCabrio coupés and convertibles.
Initially, the Quattroporte was powered by an evolution of the naturally aspirated dry sump 4.2-litre V8 engine, as used in the Maserati Coupé, with an improved power output of 400 PS (294 kW; 395 hp) and new black plastic inlet manifold instead of an aluminium cast one.
The Quattroporte's body is a steel unibody, with an aluminium boot lid and engine bonnet; the coefficient of drag is Cd=0.35. Front and rear aluminium subframes support the whole suspension and drivetrain.
A 47%/53% front/rear weight distribution was achieved by setting the engine behind the front axle, inside the wheelbase (front-mid-engine layout) and the adoption of a transaxle layout. With the later automatic transmission - fitted in the conventional position en bloc with the engine - weight distribution changed to 49%/51% front/rear.
The V8 engines of the fifth generation of the Quattroporte belonged to the 'Ferrari-Maserati F136' family; they had aluminium-silicon alloy block and heads, a crossplane crankshaft, four valves per cylinder driven by two overhead camshafts per bank and continuous variable valve timing on the intake side. F136S 4.2-litre engines in DuoSelect equipped cars used a dry sump lubrication system; F136UC 4.2-litre engines on automatic cars were converted to use a wet sump oiling system, as did the later 4.7-litre, codenamed F136Y.
