A TDI from Audi is more than just another diesel - it's actually a dynamic power unit and a rich source of driving pleasure. During the 27th Wörthersee Tour will be held in the Austrian province of Carinthia from May 21 to 25, Audi demonstrated the potential of TDI technology with a very special concept study: the Audi A3 TDI clubsport quattro is supported by the engine while providing 165 kW (224 hp) from the displacement of two liters. And with a torque of 450 Nm (331.90 pounds feet), it endows the premium compact model with a power draw of a sports car.
Audi A3 TDI clubsport quattro qualifies as an uncompromising sports machine in all other respects too technical. A six-speed transmission channels the engine power to the quattro all-wheel drive. 20-inch wheels hard to keep the power glued to the road, behind the front wheel brake discs of carbon fiber reinforced ceramic. Using the Audi drive select driving dynamics the driver can adjust the throttle response and exhaust sound characteristics, support power management, control of the ESP and shrinkage characteristics as desired.
The dynamic image presented by the scintillating A3 study is equipped with a body style and spectacular high-class, sporty interior. Parts such as wheel arch extensions and a large rear spoiler lend lasting impact to see from the outside, the interior is dominated by the racing bucket seats in the front door open and the gear lever in aluminum.
Design
Audi A3 TDI clubsport quattro has a clear air of confidence about it. Sensational style fixed directly show car three doors apart from the standard production Audi A3. It measures 4254 millimeters (167.48 inches) millimeters/2.36 inches), but only 1 385 millimeters (54.53 inches) high, - reduction in height of 36 millimeters (1.42 inches), although the big wheel. The width of the track measuring 1568 millimeters (61.73 inches) at the front (+ 34 millimeters/1.34 inches) and 1553 millimeters (61.14 inches) at the rear (+ 46 millimeters/1.81 inches).
The design team has been equipped with the Audi A3 TDI clubsport quattro with a number of new exterior parts to give a very strong and vibrant - like car racing. Finish paint is also a picture of the dynamics: the engine hood, tailgate and roof are Ibis White and Brilliant Red pelvis, while a large white figure "8" is printed on each door in reference to the year 2008. Color palette is an allusion to the colors of the national flag of Austria.
Grating single-frame has grown a bit wide, which also resulted in changes to the engine cover. Grid bars - including pronounced vertical sections - have a glossy black finish. Bi-Xenon assemblies are embellished by LED daytime running lights and wings. Front bumper incorporates a large air inlet-edged knife with a section that juts a long way forward and slightly up in the middle.
Modified front fenders feature wheel arch extensions. The doors and rear side sections - again with muscular wheel trim - receiving a new plague down bold contour. This blend harmoniously with the door frame, which itself has been addressed. The exterior mirror housing, with their hands that looks like it was designed by the wind, which is also new. Colored glass used for the rear windows gives the model yet greater visual presence.
The tail of the Audi A3 TDI clubsport quattro sports a dark gray diffuser. This is a variation of the design of the front blade, and incorporates two large circular tailpipes separate exhaust branches. Changes have also been made for the tail light assemblies. The most striking impression, however, is made by the spoiler above the rear window is very similar to the features on the new A4 race car to control the German touring car (DTM).
Inside the Audi A3 TDI clubsport quattro, the eye immediately drawn to trim the threshold of the information with "TDI Power" badging them. Meanwhile, the driver and front passenger anatomically shaped bucket seats, like those found in the Sport race cars. in the back seat in the system design with special foam padding used to sculpture them into roomy and comfortable individual seats.
The driver takes hold of a wheel with a flat-bottomed rim that is reminiscent of the elegant Audi R8 high-performance sports. Scales of the white quick, the monitor for navigation and entertainment as well as the control panel comes from the R8. Jet air outlets have multi adjustable flaps-style paths, and the usual buttons on the center console have given way to classic, sporty shift switches. The bar below the console is covered with leather, the door handles have been milled hollow to save weight. Door trim and floor mats have been newly designed.
Drive train
High-performance TDI under the hood of the Audi A3 TDI clubsport quattro is like what happened before him. Moved only 1968 cc, it is called an output of 165 kW (224 hp). Torque - the true measure of the ability of the car without effort - top of 450 Nm at encouraging (£ 331.90 ft), which is on tap from just 1750 rpm, in other words, the bottom of the same range of speed. As in the flexibility of gear, petrol diesel model leaves rivals standing.
Provide strong TDI Audi A3 TDI clubsport quattro - which is troubling at just 1475 kg (3251.82 pounds) - with charm worthy of a sports car. Sprint from 0 to 100 km / h (62.14 mph) over short 6.6 seconds and the speedometer needle is increased up to 240 km / h (149.13 mph).
The four-valve sports engine is also smarter; respond spontaneously to the throttle and pamper occupants with its low vibration running mechanics. At the sound, however, proudly states the ability for all to hear: the exhaust system is a new development, with a resonance chamber on both tailpipes to amplify the sound is rich voice control.
The engineers took as a basis undersquare engine (bore x stroke = 81.0 x 95.5 millimeters) with an output of 103 kW or 140 hp () or 125 kW (170 hp), depending on the configuration, and added to this optimized turbocharger. Advanced design of the blade which allows it to provide more air, as in the serial production version, the variable geometry of the turbine blades ensures spontaneous response.
2.0 TDI, which is managed by one of the most sophisticated control units currently available on the market, packed with high technology. Fuel injection is handled by common rail system with piezoelectric injectors and eight-hole nozzles. Test accuracy of less than five fuel injections per power stroke has the effect of reducing the noise level. This system operates at a pressure of 1800 bar - this results in extremely fine atomization of the fuel, which, with the revised piston geometry, makes the combustion process becomes very efficient.
Intake of the engine house in terms of generating vortex air flow falls, electric motors set the 'position' close so this motion is always perfectly adapted to the fall in current load and engine speed. Two balancer shaft reduces engine vibration level in the crank drive. Belt drive unit that drives the two camshafts has also been reworked to improve the acoustics of the engine.
Engine: Low emission, high efficiency
In high-performance 165 kW (224 hp) version, the 2.0 TDI unit is still able to take advantage of the high proportion of exhaust gas recirculated and sharply cooled to achieve cold combustion with low oxygen levels - resulting in a substantial reduction in untreated emissions of nitrogen oxides. Four-cylinder power unit is in compliance with the emission limits of Euro 5, which is not due to the entry into force until September 2010 and which aims primarily to reduce NOx emissions.
Ultra-efficient two-liter engine displacement-electric ratio reached 83.8 kW (113.8 hp) per liter, and torque transfer ratio of 228.7 Nm (168.68 pounds ft) liter - figures which comparable gasoline engines are only able to match.
Audi A3 TDI clubsport quattro has been designed strictly in accordance with the principle of maximum efficiency. Power is transferred by the transmission of a compact, transverse-mounted six-speed that the casing is made from lightweight magnesium. Reduced stroke shift lever can be moved quickly and precisely through a classic open gate made of aluminum. The transmission ratios have been adjusted and the components reinforced to allow high-performance TDI engine.
Engine power is transmitted to the road with virtually zero losses thanks to the quattro drive. Key components of this system is a multi-clutch which is positioned at the rear, thus further optimizing the weight distribution. In normal driving condition, clutch electronically controlled hydraulic head drive motor power the front wheels, if necessary, however, a proportion that far adjustable from the driving force can be routed to the rear.
When you change the division of power, clutch plates inside the high oil pressure, pushing them together - the procedure is completed in milliseconds thanks to a newly designed pressure reservoir for the pump. Quattro drive is a perfect power transmission system for a powerful two-door model, significantly improving traction, handling characteristics, stability and running in a straight line, regardless of the weather.
Chassis
Audi A3 TDI clubsport quattro is equipped with sports suspension that is more than capable of handling a great strength. The front suspension - a classic McPherson layout - is playing in the cradle of high strength aluminum light. A rack and pinion steering system with direct product contact with the road sensation. The help of electricity generated by an electromechanical drive unit for high efficiency, and the rate of decline as speed increases.
Rear suspension comprises four links per wheel which fulfill all manner of tasks. Link at the end of the absorbing power of the driving and braking. For the convenience of driving assistance, their configuration is relatively soft. Connection to the three transverse links, on the other hand, are rigid to direct transverse forces into the body with absolute precision. In this case, coil springs and shock absorbers are also separated from one another. Set-up is obviously the company, while the body was lowered by 36 millimeters (1.42 inches) compared to standard production.
Audi A3 TDI clubsport quattro wheels measuring up to ten impressive 9 J x 20, which in turn shod with size 265/30 ZR 20 tires.
While the brakes to the rear wheels borrowed from mass-production A3, their counterparts on the front will be out of place on a supercar: six-piston calipers exert a grip on brake discs measuring 356 millimeters (14.02 inches) in diameter. The disc itself is made from materials that have been valuable for the aerospace industry, which consists of high strength carbon fibers embedded in hard silicon carbide.
They have a lightweight construction, can withstand extreme levels of strain, are corrosion-free and have a life in the area of 300,000 km (about 186.400 miles).
Automotive à la carte with Audi drive select
Audi A3 TDI clubsport quattro boasts another highlight in the form of system Audi drive select driving dynamics. This system has control over a number of technical components that make up the driving experience. By simply pressing a button, the driver can determine at will whether these components must operate in comfort mode, dynamic mode, or "Individual" mode that allows partial programming instructions of how they interact.
In car show, Audi drive select affects the response of the engine throttle, the sound of the exhaust system, power assistance for steering, the cut-out limit for the ESP stabilization system, and damping characteristics. This is where the adaptive damping system Audi magnetic ride comes in: a magneto-rheological fluid circulating in the shock absorber piston change viscosity - and therefore the damping characteristics - in an instant when a voltage is applied.
The interaction between all these technologies makes the Audi A3 TDI clubsport quattro a thrilling road machine is very fun to drive. It darts into bends with exceptional spontaneity, and corners with a calm and stability at high speed, guided with unfailing precision by the sensitive direction. Handling limits are very high, with only a minimal amount of understeer kicking in that limit is approached. Sense of effort, convincing control is the main virtue of the A3 study - just as on all Audi models.
TDI engine - the driving force behind higher
Power, refinement and efficiency - ever since they first made their debut in 1989, the TDI engines from Audi have been synonymous with intelligent and sophisticated sporty shapes, blazing a trail for the rest of the automotive industry to follow. The victory that the diesel Audi R10 TDI racing car has benefited from two years on race tracks around the world delivered a powerful demonstration of the potential.
R10 TDI has been causing a sensation since spring 2006, with twelve-cylinder diesel engine that inaugurated a new era in the world of motor racing. 5.5-liter TDI develops more than 1,100 Nm (881.32 pounds ft) - a torque figure that positively eclipses from competitors to gasoline. Its output of 650 HP translates to a top speed of nearly 330 km / h (205.05 mph).
One of the strongest in the R10 TDI low fuel consumption. And less fuel stops means a higher speed on average - high efficiency of the car is one of the key factors in two consecutive victories in the Le Mans 24 Hours. Frank Biela (Germany), Emanuele Pirro (Italy) and Marco Werner (Germany) won in 2006 and 2007 in a style firmly. This is the same story in American Le Mans Series, where the diesel race car bearing the four Audi rings has collected a series of successes, easily securing the constructors' title in the large LMP 1 category in two years.
For the first time ever, superior TDI power from the race track can now be experienced in the series-production sports car - both the Audi TT Coupe 2.0 TDI quattro and Audi TT Roadster 2.0 TDI quattro diesel engine functions. Two-liter four-cylinder engine offers the dynamic impetus, with the power of 125 kW (170 hp) and 350 Nm (258.15 pounds ft) of torque. Nevertheless, the TDI engine in the Coupé burns just 5.3 liters of fuel per 100 km (44.38 mpg) on average - a benchmark in the sports car segment.
Also playing around lake Wörthersee is the Audi R8 TDI Le Mans, the drive train technology is closely related to the R 10 TDI. High-performance sports car is powered by a six-liter V12, a 368 kW (500 hp) output and 1,000 Nm (737.56 pounds ft) of torque push the series in the world's most powerful production TDI model to a top speed over 300 km / h (186.41 mph).
