Alfa Romeo Giulia Quadrifoglio




The Alfa Romeo Giulia (Type 952) is a compact executive car (D-segment) produced by the Italian car manufacturer Alfa Romeo. It was premiered in June 2015, with market launch scheduled for February 2016, and it is the first D-segment offering by Alfa Romeo after the production of the 159 ended in 2011. The Giulia is also the first high volume production Alfa Romeo in over two decades to use a longitudinal engined rear-wheel drive platform, since the 75 was discontinued in 1992.

Alfa Romeo also makes the gorgeous 4C, a compact 8C.

Quadrifoglio

The high-performance Giulia Quadrifoglio ("four-leaf clover") was the first model in the new Giulia range to be revealed, in Italy in June 2015. It made its official world debut at the 2015 Frankfurt Motorshow. The Italian Police took delivery of the 2 Alfa Romeo Giulia Quadrifoglios wrapped in a navy blue paint that it's so inky virtually black, it sports red stripes over the car and it has flashing lights over its chin spoiler and white roof.


The Quadrifoglio is powered by an all-aluminium, twin-turbocharged 90° V6 petrol engine, with a single-cylinder displacement of just under half a litre, for a total of 2,891 cc (176.4 cu in). This engine was developed exclusively for the Quadrifoglio by Ferrari technicians and it is related to Ferrari's own twin-turbo F154 V8.,[9] sharing the California T's bore of 86.5 mm (3.4 in) and stroke of  82.0 mm (3.2 in). It produces 510 metric horsepower (375 kW; 503 bhp) at 6,500 rpm, and 600 N·m (440 lb·ft) of torque between 2,500 and 5,000 rpm, and its turbo boost pressure reaches up to 35 pounds per square inch (2.4 bar) at the peak. Thanks to cylinder deactivation (with the ability to switch off three of the six cylinders),this model achieves a fuel consumption of 8.5 litres per 100 kilometres (33 mpg-imp; 28 mpg-US) and CO2 emissions of 198 g/km, in the combined cycle.


According to Alfa Romeo, the Giulia Quadrifoglio can accelerate from 0 to 100 km/h (62 mph) in 3.9 seconds and come to a standstill from that speed in 32 meters, when fitted with carbon ceramic brakes. This model has also lapped Nurburgring's Nordschleife circuit in just 7:39.0, which is record for a saloon car. In September 2016 was published new lap record with automatic transmission version, new record was timed at 7 minutes and 32 seconds.

The Quadrifoglio weighs 1,524 kilograms (3,360 pounds) (DIN) for a power-to-weight ratio of 3 kg/PS. This is achieved thanks to the Quadrifoglio sharing the other models' composite and light alloy construction, as well as featuring a roof and engine bonnet made of carbon fibre.


From the front, the Quadrifoglio distinguishes itself from the rest of the range by a specific front bumper—with a carbon fibre splitter and enlarged air intakes for the twin intercoolers and for the brakes—and by a bonnet pierced by two cooling outlets for the engine bay. On the sides, the front wings also have outlets to extract air from the wheel wells, and bear Quadrifoglio badges; the side skirts are specific to the model, as are the 19-inch alloy wheels. At the rear a low-profile carbon fibre spoiler is applied to the boot lid, and a rear diffuser makes up the lower half of the bumper, flanked by quadruple exhaust tips. Working in conjunction with the faired-in underside, the diffuser is fully functional in generating downforce—as at the front is the "Active Aero Splitter", which can vary its angle of attack by 10°, moved by electric motors. Alfa Romeo claims these active aero features to be firsts in the Giulia's market segment and are able to generate up to 100 kg of downforce at 300 km/h. The Giulia Quadrifoglio has a drag coefficient (Cd) of 0.32.

Mechanically, this model is fitted with a torque vectoring rear differential, able to send 100% of the torque to the left or right wheel, and, on the model which debuted in July 2015, a six-speed manual transmission, made by ZF. The braking system uses carbon ceramic rotors, six-pot front and four-pot rear calipers, and auxiliary rear calipers for the parking brake. The electronic stability control and the traditional brake servo are combined in a single electromechanical system.



Inside, the dashboard is part-trimmed in leather and carbon fibre trim and the engine start button is located on the multi-function steering wheel. In addition, the driver is offered Alfa Romeo's "DNA" dynamic control selector, which is placed on the centre dashboard. Driving modes include the traditional "Dynamic", "Natural" and "Advanced" modes, plus new "Efficient" (for increased fuel economy) and "Racing" (for high performance).

The launch prices of the Quadrifoglio in Italy range from €79,000 to €95,000 for a version with full racing kit, which includes carbon ceramic brake discs and ultra-light carbonfibre sport seats.
