The Porsche Carrera GT is Beautifully Engineered

Also on the list of best exhaust note ever

The development of the Carrera GT can be traced back to the 911 GT1 and LMP1-98 racing cars. Due in part to the FIA and ACO rule changes in 1998, both designs had ended. Porsche at the time had planned on a new Le Mans prototype for 1999. The car was initially intended to use a turbocharged flat-6, but was later redesigned to use a new V10 engine, pushing the project back to planned completion in 2000. The V10 was a unit secretly built by Porsche for the Footwork Formula One team in 1992, but later shelved. The engine was resurrected for the Le Mans prototype and increased in size to 5.7 litres. Unfortunately the project was canceled after two days of testing for the first car, in mid-1999, mostly due to Porsche’s wish to build the Cayenne SUV with involvement from Volkswagen and Audi, thus requiring engineering expertise to be pulled from the motorsports division. It was also speculated that VW-Audi chairman Ferdinand Piëch wanted Audi’s new Le Mans Prototype, the Audi R8 not to face competition from Porsche in 2004.

The Carrera GT is powered by a 5.7 litre V10 engine producing 612 PS (450 kW; 604 hp), whereas the original concept car featured a 5.5 litre version rated at 558 hp (416 kW). Porsche claims it will accelerate from 0 to 100 km/h (62.1 mph) in 3.9 seconds and has a maximum speed of 330 km/h (205 mph), although road tests indicated that in reality the car can accelerate from 0-60 mph (97 km/h) in 3.5 seconds and 0-100 mph (160 km/h) in 6.8 seconds. A traditional six-speed manual transmission is the only available transmission.

The Carrera GT has large side inlets and air dams that help cool the large V10 engine framed by the carbon fibre rear bonnet. Fitted with Porsche’s latest Carbon fibre-reinforced Silicon Carbide (C/SiC) ceramic composite brake system, the 15-inch (380 mm) SGL Carbon disc brakes make an impressive appearance underneath the 19 inch front and 20 inch rear wheels. Similar to other Porsche models, such as the 911, the GT includes an automated rear wing spoiler which deploys above 70 mph (110 km/h).

Notable technology includes a pure carbon fiber monocoque and subframe, dry sump lubrication and inboard suspension. The carbon fiber monocoque and subframe were produced and assembled by ATR Composites Group of Italy. The spoiler of the Carrera GT extends into the air when the car reaches about 70 miles (110 km) an hour and evens out the air flow, which causes less drag. The Carrera GT radiator is about five times the size of a 911 Turbo’s. Front and rear suspension consist of pushrod activated shock absorbers and dampers with front and rear anti-roll bars.
