2017 Audi RS 3 Sportback 400 HP | Walkaround EXTERIOR + INTERIOR CAR DESIGN [GOMMEBLOG]
2017 Audi RS 3 Sportback 400 HP | Walkaround EXTERIOR + INTERIOR CAR DESIGN [GOMMEBLOG] – Behind the impressive performance of the Audi RS 3 Sportback is the world’s most powerful production five-cylinder engine – the 2.5 TFSI. It delivers 294 kW (400 hp) of output – 33 hp more than the predecessor engine – and is 26 kilograms (57.3 lb) lighter thanks to its aluminum crankcase, among other features. Its maximum torque of 480 Nm (354.0 lb-ft) is available at engine speeds as low as 1,700 rpm and remains constant up to 5,850 rpm. That’s how the RS 3 Sportback is able to sprint from 0 to 100 km/h (62.1 mph) in 4.1 seconds. The effect of this extraordinary tractive power is intensified by the five-cylinder’s unmistakable sound, which comes from having the ignition alternate between directly adjacent cylinders and widely spaced ones. On request, Audi will increase the electronically limited top speed from 250 km/h (155.3 mph) to 280 km/h (174.0 mph).
For better mixture preparation, the new 2.5 TFSI engine employs dual injection into the intake manifold and into the combustion chambers. On the exhaust side, the Audi valvelift system controls the duration of valve opening depending on the throttle and engine speed – for moderate fuel consumption at low and partial load as well as more spontaneous throttle response and a high level of tractive power at full load. In the New European Driving Cycle (NEDC) the RS 3 Sportback uses 8.3 liters of fuel per 100 kilometers (28.3 US mpg), which equates to 189 grams of CO2 per kilometer (304.2 g/mi).
The S tronic seven-speed dual-clutch transmission and quattro permanent all-wheel drive transfers the power of the five cylinders to the road. And the electro-hydraulic multi-plate clutch distributes the drive torque variably between the axles. The sportier the driving, the faster and more often a large share of the torque reaches the rear axle. quattro management is integrated as a standard feature in the dynamic handling system Audi drive select, as are the steering,
S tronic, the engine management, the adjustable exhaust flaps, and the optional RS sport suspension with adaptive damper control. The driver can individually vary the operation of these components between three modes – comfort, auto and dynamic. Handling is perfected using the Electronic Stabilization Control (ESC) with wheel-selective torque control and the sport mode specially tuned for the RS.
Together with progressive steering, the four-link rear axle, and the tight suspension setup lowered by 25 millimeters (1.0 in) relative to the A3, the RS 3 Sportback combines fascinating dynamism with superior stability. Compared to that production model, the track at the front axle of the RS 3 Sportback is wider by 20 millimeters (0.8 in) – and the wheel arches are accordingly flared wider. As standard, Audi includes 19-inch cast wheels and 235/35 tires, and brake disks with a diameter of 310 millimeters (12.2 in). Alternatively, customers will be able to choose carbon-fiber ceramic disks in front. At the rear axle, brake disks with a diameter of 310 millimeters (12.2 in) are used.
