Sportback Audi RS3 afloat in the snow - Raw

Sportback Audi RS3 afloat in the snow - Raw Video Clips.





After years of waiting, Audi has officially unveiled the RS3 Sportback. In essence, the car from the same supercharged 2.5-liter five-cylinder engines in the TT-RS 250 kW (340 hp / 335 hp) and 450 Nm (332 lb ft) of torque is guided found. It is associated with all-wheel drive and a seven-speed S tronic transmission, which enables to 1575 kg (3472 lb) RS3, acceleration from 0 to 100 km in 4.6 seconds and hit an electronically limited 250 km (155 mph). Impressively, the caraverage fuel consumption of 9.1 liters per 100 kilometers (25.85 U.S. mpg) and CO2 emissions of 212 g / km. To ensure the management star, Audi's engineers installed a heavy duty aluminum sport suspension with MacPherson struts in front and a four-link rear setup. They also added a powerful braking system with ventilated discs measuring 370 mm 310 mm front and rear axle. The design is the RS3 ago by aggressive bumpers, grill charcoal and carbon fiber reinforced emergingPlastic (CFRP) and mudguards. Among other goodies xenon headlights, a lower ride height (25 mm lower than an A3 stock), aerodynamic side skirts, matte aluminum trim and a dual exhaust system and 19-inch alloy wheels. Inside, the interior with sports seats in nappa leather (with contrast stitching in silver), Piano Black (Race or aluminum) structure, a wheel flat, and a revised driver information system, equipped with a stopwatch. On sale early next year will cost for the RS3of ...

Two ways to increase power - Supercharger vs. Turbocharger

Two ways to increase power - Supercharger vs. Turbocharger

Exhaust System

You have probably heard or read somewhere that some cars are equipped with a compressor and more cars are now equipped with a turbocharger. This is the standard for most cars with smaller engines. Car manufacturers want to increase the power of their machines, without the size of the engine.

You may also know that some people have an after-market turbocharger or supercharger, took his car. While both devices are to increase the performance of your car, there are somecritical differences between a compressor and turbocharger.

A definition of a compressor is "make every piece of equipment that the compressed air supplied by a motor so that the chamber be filled without enlarging the space. Read it carefully you can see that a turbocharger as a compressor may, for are classified the same thing. In fact, many people think they have to be identical in their objectives, but differ in their approach to the growingPS.

However, there are some important differences between the design of a compressor and turbocharger. A compressor is usually driven by the engine, usually with a belt, sometimes with a chain or gears. A turbocharger uses exhaust gases to a turbine, which in turn compresses the incoming air. So both systems are designed to compress the air and more oxygen available to the engine. The more oxygen the engine gets more power to spend it. TheThe main difference is how each device is activated.

If we were to compare side by side, the compressor has several advantages compared to the turbocharger.

Since the compressor is driven directly by the engine, there is no delay before the compressor starts to compress the incoming air. Once you increase your speed, so has the power, this is not true for a turbocharger.

A turbocharger on the other hand, is delayed until the fumes had the opportunity to buildbefore there is enough electricity to power the gas turbine and then the compressor. Since a turbocharger has a built-in delay, do not get an immediate increase in performance when you step on the throttle means. A newly developed turbocharger may have reduced this limitation, but there is still a certain amount of delay between the demand for additional power and it actually receives, unlike the performance of a compressor.

A compressor has less potentialHeat problems of a turbocharger. This means that the compressor operates at a higher efficiency compared to the turbocharger.

Another advantage is that for a small car with a small engine that the installation of a compressor can actually increase the gas mileage of the vehicle.

The turbocharger is often more efficient than a compressor, because the energy is "wasted" from the exhaust into the exhaust system as a current source. On the other hand, the facta turbocharger, which causes increased pressure in the exhaust system, took power. In addition, a turbocharger is less lively, until the engine runs at higher speeds.

In considering whether you want a compressor or a turbocharger, note that you will find it easier to install a compressor of a turbo, but it is expensive to buy a compressor as an aftermarket turbocharger. One of them is a way to increase the performance of your vehicle. But once againWarning, you must be familiar with basic tools for mechanics at hand and follow the instructions. Or would you be better having a professional do the installation.
