Next-generation Audi RS3 Sportback will stick to the 2.5-liter five-cylinder engine

Article by Christian A., on October 15, 2014

Although we expected a 2.0-liter TFSI for the next-generation Audi RS3 Sportback, it appears that the German company decided to keep the 2.5-liter five-cylinder powerplant used by the current engine. Based on the MQB platform, the new RS3 Sportback will be 55 kg lighter and will use reengineered springs and dampers.

Moreover, the new sports car will be 25 mm closer to the ground when compared with the S3 and will arrive with a wider track and optional wider front tires. According to Quattro boss Stephan Reil, the 2.5-liter engine will deliver around 360 hp and power will be delivered through a permanent all-wheel drive system through the standard seven-speed S tronic transmission.

As a result, the new RS3 will be capable to accelerate from 0 to 100 km/h (62 mph) in around 4.0 seconds. For those who don’t know, the current Audi RS3 Sportback uses the 2.5-liter TFSI four-cylinder engine that generates 340 hp (250 kW) and 450 Nm (332 lb-ft) of torque.

Using a permanent Quattro all-wheel drive system and an seven-speed S tronic transmission, the RS3 Sportback sprints from 0 to 100 km/h (62 mph) in 4.6 seconds, while top speed is 250 km/h or 155 mph.

The vehicle has a total weight of 1,575 kg (3,472 pounds) and returns a fuel economy of 9.1 l/100 km or 25.85 US mpg, while CO2 emissions are 212 g/km. The next-generation RS3 Sportback will be faster, more powerful but also more fuel-efficient than the previous model.

The sportiness of a sporty car is determined partly by its power-to-weight ratio. The new Audi RS3 Sportback has a generous power-to-weight ratio of 1 hp-has- 4.14 kg. (9.1 lbs), as made possible by the fact that the five-door compact has a curb weight of just 1,520 kg. (3,351.0 lbs). Compared to its predecessor, the new RS3 Sportback is around 55 kg (121.3 lb) lighter.

Making this value possible is the fact that the Audi RS3 Sportback is underpinned by the Volkswagen Group's modular transverse matrix (MQB) that makes use of a lightweight construction concept. For instance, several components of the occupant cell are made from ultra-high-strength, hot-shaped steel, while the bonnet is made from aluminum.

Further, the new RS3 Sportback boasts of a favorable axle load distribution, as realized by the orientation of the engine and the location of the multi-plate clutch (front of rear axle) and the battery (behind rear axle).

Even at a glance, the Audi RS3 Sportback shows its performance potential. Its front end is defined by a Singleframe grille with a high-gloss black, honeycomb-look grille and a matt aluminum-look frame.

Charge air is channeled through an air inlet located below the license plate frame while air is channeled to the engine's supplemental radiator and transmission oil cooler via large air inlets framed by bold contours. Meanwhile, the front apron features an integrated blade extending upward into the air inlets to form a vertical dividing bar.

When viewed from the side, the new RS3 Sportback reveals a large roof spoiler, wider front fenders, matt aluminum-look mirror housings and chiseled side sills.

On the rear, the new RS3 Sportback is marked by a prominent bumper, two large oval tailpipes and high-gloss black diffuser insert with honeycomb grille and four bars. The Singleframe grille and the rear hatch feature RS3 badges.
