Audi has released the first technical details of the new RS 3. The heart is still the five-cylinder turbo with 400 hp of maximum power, but the absolute protagonist will be the new four-wheel drive system, which replaces the previous one to minimize the tendency to understeer. Here are the acceleration and maximum speed data

What distinguishes a fast car from a true sports car? According to the interpretation currently in trend, it would be the torque vectoring to the rear axle to make the difference. At least that’s how Audi draws a clear line between its ultra-fast compacts. At the top of the A3 range shortly there will no longer be only the very fast S3 with 310 HP of power, but will be added the RS 3 with the renewed 2.5 Tfsi da 400 Cv e 500 Nm of couple. In addition to promising significantly higher performance than the S3, the Racing will receive a dedicated powertrain, the result of the synergy with Volkswagen, which will allow it to play on equal terms with Mercedes Amg A45s and Cla45s.
The biggest innovation introduced by the new Audi RS 3 is the new lateral dynamics control system Torque Split. At the end of the cardan shaft there is no longer the classic Haldex multi-disc clutch, but the drive torque is discharged directly onto the entire rear axle. Here it is divided between the rear wheels by means of two clutches positioned on the individual drive shafts, with the input coming from sensors positioned at the key points of the powertrain and the steering system. These sensors determine the amount of power to be redirected to all four wheels also depending on the weather conditions, recognizing the state of the asphalt and working together with the system that brakes the inside wheel at the bend, already present on the S3.
all behind, if you want it
Thanks to the Torque Split, Audi promises a more refined driving dynamics than in the past: the possibility of reaching up to 1,750 Nm of torque on a single rear wheel allows the new RS 3 to have neutral driving behavior under normal conditions, or more oversteer in Dynamic, RS Performance and RS Torque Rear modes. The last mentioned offers the possibility to perform in controlled transoms: in fact, the rear axle can receive up to 100% of the drive torque. With this feature, the new generation of the RS 3 is shaping up to be the most fun Audi has made so far. To emphasize this aspect, the sportier setups have been optimized to accommodate Pirelli PZero Trofeo R semislick tires, which will be available as an option.
Since launching in 2011, the Audi RS 3 has stood out for the five-cylinder turbo 2.5 Tfsi, an engine that, due to its power, smooth delivery and sound, has attracted many enthusiasts. The latter will be pleased to know that for this generation of RS 3 (called 8Y) the 5-cylinder has been re-proposed in an updated version. Although the maximum power declared by Audi has remained unchanged, 400 hp, it is now delivered between 5,600 rpm and 7,000 rpm, therefore lower and longer than the outgoing model.
New Audi RS 3: super performance
There is instead an increase in maximum torque, ranging from 480 to 500 Nm, available between 2,250 and 5,600 rpm. This tuning made it possible to shorten the sprint from 0 to 100 km / h, for which Audi declares a time of 3.8 seconds. As for the top speed, it will be limited to 250 km / h, with the possibility of unlocking the limiter at 280. Or, by ordering the RS Dynamic package and carbon ceramic brakes, the speed will be limited to 290 km/h, a record for this category. The gearbox is the well-known seven-speed S tronic double clutch, which has been strengthened to manage the increase in torque and sportier ratios.
The suspension layout of the new Audi RS 3 features a McPherson at the front, while at the rear we find a four-link suspension with separate shock absorber arrangement, while the stabilizer bar has been adapted to accommodate the new transfer case on the drive shafts. The car is 10mm lower than the S3 (thus 25mm compared to the A3) and the negative front camber is one degree lower than the S3, while the rear has been increased by about 0.5 degrees.
Specific sports suspension for the RS 3 will be standard: they feature new shock absorbers, whose response is managed through a new valve system designed to ensure greater reactivity. Available as optional adaptive suspension RS plus, which continuously vary the suspension setting according to the asphalt conditions, the driving situation and the drive select mode. Audi promises a high level of customization of driving dynamics and, among the various calibrations available, there is a specific one to run on circuits with uneven surfaces, such as the Nurburgring. So we just have to wait for the official debut, scheduled for July 19.
