Audi’s RS range has two new ‘performance’ models -- the RS 7 Sportback and RS 6 Avant. These two additions make the RS badge proud with a 45PS increase in power to 605PS and 50Nm additional torque resulting in 750Nm total torque.
While it improves the output, resulting to a 3.7-second record for a 0-60mph sprint, the two models boast of having excellent fuel economy the RS is known for. In fact, it has the same low fuel consumption figures of its ‘standard’ counterparts that are the best in their class.
The peak 605PS power output and maximum torque of 700Nm are due to the 4.0-litre TFSI engine. But it comes with the overboost function capable of increasing torque to as high as 750Nm. For those interested, the RS 6 Avant and the RS 7 Sportback will be available in the UK for orders starting in November with the first deliveries scheduled for next February.
The RS 6 performance will be available at £86,000 OTR while the RS 7 comes in at £91,600 OTR. The performances of the RS 6 and RS 7 have been greatly improved with acceleration from 0 to 62mph achieved in merely 3.7 seconds, which is 0.2 seconds faster than the standard model.
The two models are also faster by 1.4-seconds to go from zero to 124mph with a 12.1-second record. The top speed has been set at 155mph but this can be increased to 174mph as an option. For those who want the dynamic package, the maximum speed is increased even higher to 189mph.
Even with its 45PS output boost, the V8 biturbo power unit manages to retain the standards of fuel economy and emissions. For the RS 6, fuel economy is 29.4mpg with emissions at 223 g/km of CO2. The RS 7 on the other hand has 29.7mpg with 221 g/km of CO2.
Its 4.0 TFSI engine was upgraded from one that had a management system capable of increasing the rpm and boosting the pressure to a COD (cylinder on demand) system that will activate only four of its eight cylinders if only part of the load is tapped.
The upgrades were mainly a result of engineering expertise collected over time while developing the RS undertaken by Audi and quattro GmbH. While the engine for the RS 6 Avant and RS 7 Sportback can be considered as already extreme in terms of performance, its potential has been maximized even further through the eight-speed tiptronic transmission.
With this, the driver has the option to choose whether to change the gears manually or use modes D or S. This can be achieved through two ways: using the shift paddles found on the multifunction steering wheel or tapping the selector lever.
In manual mode, the rev limit is shown through the option head-up display or the shift indicator that is on the driver information system. Another feature in the two models is the quattro permanent all-wheel drive.
This allows greater flexibility and power delivery especially when the vehicle is on the road as it can distribute whatever torque is needed through the center differential. Under the usual configuration, 40% of the torque usually goes to the front axle while the remaining 60% flows to the rear.
Under this system, the wheel-selective torque control makes the needed intervention. Furthermore, the rear axle also comes with the standard sport differential which further allows the torque to be distributed between the outside and the inside of the wheel.
Owing to the dynamic set-up, the RS 6 and RS 7 have an adaptive air suspension that results in its body being lower by 20 millimetres. In addition, there may be variations on the integrated damping control because of the driving style, the mode under the drive select, and the road conditions. However there is also the option to use the tauter RS sports suspension that has the Dynamic Ride Control (DRC).
Either of the two can be balanced with the dynamic steering that while optional, has a continuously variable steering ratio. The function of the different key components can be changed by the driver through the Audi driver select.
This includes not just the engine and sound management but also the sport differential, steering, and tiptronic transmission. A number of the RS performance models can even make this driver select process easier and that much quicker.
Take the R8 sports car for example. With just the touch of a special button placed on the RS sport leather multifunction steering wheel, the driver can switch between individual , dynamic, comfort, and auto modes without the need to take eyes off the road. For the RS 6 and RS 7, the performance is given a boost by aluminium cast 21-inch wheels with the former using 285/30 tyres while the latter has 275/30 tyres.
Even as its four brake discs are all internally ventilated and are designed with a wave design that reduces weight, Audi gives the option to use discs made of carbon fibre-ceramic. There are more striking design details that further strengthen the claim on why these two new RS models belong to the top.
There include the bumpers that are highlighted with a heavy profiled diffuser insert at the back and large air inlets on its front. The same can be said for the flared side sills and the honeycomb grille in gloss black that is standard for RS models.
The exterior of the RS further emphasizes its performance with the well-known quattro logo on both the matt titanium-look detail and the air inlet duct. On the inside, the super sports seats have side bolsters with head restraints already integrated to them.
The seats are covered in a leather and Alcantara blue and black combination along with a honeycomb patter and matching stitching on its armrests.
This stitching further extends to floor mats and control elements. It also has knee pads that have been finished in Alcantara as well with the inlays in a carbon blue thread. This is a carbon material that has blue thread interwoven to it.
