Delivering 400 hp and weighing in at just 1,120 kilograms, the latest 911 GT3 Cup for the Porsche
Michelin Supercup reaches a power-weight ratio of 2.7 kgs/hp – the best power-weight ratio
in the history of the Porsche makes cups. Fitted with the high performance Porsche Ceramic Composite
Brake PCCB exclusively for this racing series, a sequential six speed gearbox and featuring a new aero kit,
this sportscar – which is based on the current 911 (Type 997) – set new record laps on all tracks visited
by the Porsche Michelin Supercup in 2005. The light weight of the latest GT3 Cup is reached through the use of carbon-fibre composite materials for the doors, rear lid, rear wing and through PCCB, which reduces unsprung masses by 20 kg compared to the steel brake. The in-house developed brake system sets new standards in response, fading stability, weight and durability. Thanks to an aerokit consisting of a specially designed front and rear, an adjustable rear wing, adjustable spoilers at the wheel arches and two different front spoilers, the body generates 40 percent more downforce than its 996-based predecessor. The intake and extraction of air from the radiators and brakes were also further optimised. Delivering 400 hp (294 kW) at 7,300 rpm the latest spec of the well proven 3.6-litre six-cylinder boxer delivers the highest output in the history of the makes cups. Maximum torque is reached at 400 Nm with 6,500 revs per minute. The maximum engine speed is 8,200 rpm. The sequential six-speed dog-type ‘box features a power shift system with ignition cut for very quick upshifting at full throttle without use of the clutch. Very close ratios ensure that the engine runs in its optimum rev range with the gearing considerably shorter than in the road-going 911. The suspension, with a Porsche optimised strut front axle and the Porsche multi-link rear, corresponds closely to the road-homologated model. Ride height, camber and track as well as anti-roll bars are continuously adjustable. |
