Audi S5

The Audi S5 is a sports version of the A5, (A5 information), has a 354 hp engine. It costs € 63,160 with six-speed manual transmission and € 65,850 with automatic "Tiptronic" (six walks). Later, a more powerful version, called the RS5.

The S5 measured 4.64 m long, 1.85 m wide and 1.37 m in height (the image). Has a size intermediate between the A4 and A6 saloons. Cupés of four seats, the closest is the Mercedes-Benz CLK and BMW 3 Series Coupé.

The S5 has a gasoline engine, air, with FSI direct-injection eight-cylinder V 90 °, and 4.2 liters of displacement. Have admission and distribution variables. Reaches a maximum power of 354 hp at 7000 rpm and maximum torque of 440 Nm at 3,500 rpm.

This engine gives the S5 more power than in the A6 or A8 (both 350 hp) and less than the RS4 and the R8 (420 hp).

The S5 has a top speed limited to 250 km / h. Interestingly, the variant of S5 with automatic consumption is much lower than the manual (10.1 instead of 12.1 l/100 km) and a slightly worse because of acceleration (comparative form of both versions).

Among the items of equipment that has serial are six airbags, stability control (ESP), air conditioning, dual-xenon headlights (daylight the project a strip diodes which are integrated into the lighthouse, picture, not separated as in Audi S6), sports front seats with electric adjustment, electric parking brake, sport suspension and alloy wheels 18 ". Optionally you can have ventilated seats, a feature that is unavailable elsewhere in the A5 range.

With respect to A5, the S5 has some aspect of the changes the body and inside, (more information).

The impression it gave me the S5 is not much different from the one sent to me A5. If the A5 is a car available for use every day for your convenience and practicality, the S5 also is.

The suspension of the S5 is not too hard and the engine noise is noticeable and severe, but their sound is not very loud inside. I has become clear that in conducting the S5 is a relatively docile and easy car to drive for power, a sport designed for very twisted road.

The 354 hp engine has a nice sound and a very direct response to the accelerator. It is an engine with a good performance but does not seem much higher than it has a 306 hp BMW 335i. Indeed, the BMW is just a bit slower, but its consumption is much lower (comparison table).

Has total traction with asymmetric distribution of engine power. When the slide is the same in all the wheels, the front makes a 40 per cent of the force that drives the car and the rear by 60 percent. The center differential has a torque that can vary the force between the drive wheels when sliding between them is not the same. The total traction makes it possible to accelerate the departure of fund turns over closed without losing an iota of motor.

The frame of the A5 and S5 is steel, such as the A4 or A6 (not aluminum, as the A8). The wheelbase is 2.75 m, slightly higher compared to its length than normal passenger cars Audi longitudinal engine (more information).

The suspension is basically like an A4 or an A6, but are dimensionally different. Front has a deformable parallelogram with two pairs of arms superimposed. Behind also carries a deformable parallelogram and a triangle with your arms.

The suspension of the S5 is harder than in an A5, Audi has added an additional element between the turrets of the front suspension to give more rigidity to the structure. Tires may be 245/40 or 255/35 R 18 R 19.

The boot measures 455 liters of volume. 5 l is greater than that of a BMW 3 Series Coupé, no other coupe to 4.8 m in length that has a bigger trunk. Can be expanded by folding the rear support, which is divided in two.
