Introduction to the Audi RS 5 Coupe
The Audi RS 5 Coupe unites athletic power with harmonious aesthetics and practical everyday usability. Its newly developed 2.9 TFSI bi-turbo engine produces 331 kW (450 hp) and delivers 600 Nm (442.5 lb-ft) of torque. The standard Quattro drive distributes the power to all four wheels, guaranteeing traction, dynamism, and stability well into the limits of the possible. The car also impresses with innovative infotainment solutions and the intelligent interplay between numerous driver assistance systems.
Design and Exterior Features
The new Audi RS 5 Coupe demonstrates its sporty character as a Gran Turismo at first glance. The designers drew inspiration for the car from the distinctive motorsport details of the Audi 90 Quattro IMSA GTO. The front, sides, and rear exhibit RS-typical differentiation. Measuring 4,723 millimeters (185.9 in) in length, the second generation of the RS 5 Coupe is 74 millimeters (2.9 in) longer than the predecessor model. The height is 1,360 millimeters (53.5 in), which is 6 millimeters (0.2 in) lower than previously. At 1,861 millimeters (73.3 in), the vehicle’s width is almost the same as before. Compared to the A5 Coupe, the Singleframe radiator grille appears broader and flatter thanks to its new honeycomb structure. It bears both the Quattro lettering and the RS 5 emblem. Beneath it, a blade in a contrasting color runs between the air inlets, connecting these with one another. These also adopt the three-dimensional honeycomb structure and underline the dynamism of the Audi RS 5 Coupe. The standard headlights use LED technology, while the optional Matrix LED headlights are distinguished by their darker tinted bezels. Alongside them are additional lateral air inlets, which make this top-performing athlete appear even wider and more aggressive.
A sharply drawn shoulder line in the form of the characteristic wave lends the new Audi RS 5 Coupe an emotively elegant expression. For the first time, it now has a three-dimensional form and thus creates an interplay between light and shadow. Quattro blisters on the flanks emphasize the pronounced bulges over the wheel arches, which have been widened by 15 millimeters (0.6 in). The widened door sills are painted in the vehicle color and also feature inserts in black or optionally carbon. The exterior mirror housings are in a matt aluminum look and optionally also in carbon, in the vehicle color, or in black. Sporty accents on the short rear end come in the form of the RS-specific diffuser insert, the oval tailpipes of the RS exhaust system, and the vertical air outlets on the outer edges of the LED rear lights. A surface-mounted spoiler lip in black, or optionally in carbon, rounds out the image. The styling packages – gloss black, carbon, and matt aluminum – provide even more customization options. Overall, the Audi RS 5 Coupe is available in seven colors, with Audi Sport also offering the exclusive paint color Sonoma green metallic. In the Audi exclusive range, there are also numerous freely selectable exterior paint finishes available.
Engine and Performance
With the newly developed 2.9 TFSI, Audi has drawn upon the legendary 2.7 liter V6 from the first RS 4 Avant, which was produced between 1999 and 2001 and delivered 280 kW (380 hp). Just like the 2.7-liter engine, the new high-performance V6 is also designed as a bi-turbo engine. In comparison with its direct predecessor, a naturally aspirated, high-revving V8 unit, its pulling power and efficiency attain a whole other dimension. From 1,900 to 5,000 rpm, the 2.9 TFSI supplies the crankshaft with an impressive 600 Nm (442.5 lb-ft) of torque, which is 170 Nm (125.4 lb-ft) more than in the previous model. With its 331 kW (450 hp) – which equates to a power ratio of 155.5 hp per liter displacement – the unit accelerates the new RS 5 Coupe from zero to 100 km/h (62.1 mph) in 3.9 seconds, which is six-tenths of a second faster than before. If the customer orders the RS dynamic package, Audi increases the electronically restricted top speed from 250 km/h (155.3 mph) to 280 km/h (174.0 mph).
The 2.9 TFSI was derived from the 3.0 TFSI used in the Audi S5. Because of the greater forces inside the engine, the valve lift has been shortened by 3 millimeters (0.1 in) to 86 millimeters (3.4 in). With its unchanged bore of 84 millimeters (3.3 in), the displacement is 2,894 cm3. The crankcase integrates thin-walled cylinder liners made of gray cast iron, and the crankshaft main bearing has a 2-millimeter (0.08 in) larger diameter compared with the 3.0 TFSI. The crankcase is created from an aluminum-silicon alloy by means of sand casting and weighs just 34 kilograms (75.0 lb). The so-called “deep-skirt” design extends the walls of the crankcase far downwards, which also saves weight. The entire engine weighs just 182 kilograms (401.2 lb), which makes it 31 kilograms (68.3 lb) lighter than its V8 predecessor. Gross weight and axle load distribution are the predominant beneficiaries of this in the new Audi RS 5 Coupe.
Typically, Audi positions the exhaust side within the V angle. Each of the two turbochargers on the 2.9 TFSI is assigned to a single-cylinder bank and can build up a maximum of 1.5 bar charge pressure. Like with all new V6 and V8 engines from Audi, the turbochargers are installed within the 90-degree angle of the cylinder banks, and thus the exhaust side of the cylinder heads is on the inside, while
