The Audi R8 is a sports car with a longitudinally mounted mid-engine, and uses Audi’s trademark Quattro permanent four-wheel drive system. It was introduced by the German automaker AUDI AG, a subsidiary of Volkswagen Group, in 2006. The car was exclusively designed, developed, and manufactured by AUDI AG’s high performance private subsidiary company, Quattro GmbH, and is similar to the Lamborghini Gallardo. The fundamental construction of the R8 is based on the Audi Space Frame, and uses an aluminium monocoque which is built around space frame principles. The car is built by Quattro GmbH in a newly renovated factory at Audi’s ‘aluminium site’ at Neckarsulm in Germany. In 2005, Audi announced that the name of the successful Audi R8 race car would be used for a new road car in 2007, the Audi R8, based on the Audi Le Mans quattro concept car, was officially launched at the Paris Auto Show on 30 September 2006. The Audi R8 is used as a safety car in Deutsche Tourenwagen Masters and British Superbike Championship racing series.

As the first Audi mid-engined sports car, the Audi R8 combines Audi’s experience gained from numerous motorsport triumphs with groundbreaking design and the acknowledged technological expertise of the brand. This expertise has led to the slogan ‘Vorsprung durch Technik’ becoming a byword for leading-edge technology both on the race track and on the road. To produce the R8 at quattro GmbH, seventy workers fit 5,000 unique parts by hand. The factory at Neckarsulm, redeveloped at a cost of €28 million. The two-seat coupé is currently available in Bahrain, Europe, the United States, Canada, Australia, Japan and South Africa, India, Japan, Taiwan, South Korea, Philippines, Hong Kong and Vietnam, and has been available in China, Turkey, United Arab Emirates, Singapore and Indonesia.

There aren’t too many cars that force a fundamental reappraisal of a marquee’s core values but the Audi A8 W12 is most definitely one of them. Prior to this car’s appearance, Audi could best be described as a marquee that offered high quality, high technology and advanced engineering wrapped up in stylish yet low-key packaging. The A8 W12 doesn’t do `unobtrusive’ very convincingly. This more confident Audi flagship is no shrinking violet.

The Multi Media interface is one of the unique technological, comfort and luxury features of the Audi A8. The 12 cylindered 450hp engine variant of the A8 powers the vehicle to 100 Km from 0 within just 5.1 seconds. Impressive power output propels the vehicle to greater speeds with a 6 speed multitronic or tiptronic automatic transmission. The “Quattro four-wheel drive offers all sorts of foul weather grip advantages that are quite beyond the Audi’s rivals”. The vehicle also hoards an Automatic Climate Control Air Conditioning System to suit different climatic conditions and maintain the temperature feel of the passengers at a certain level. The very first sight of the car would either tell you that it is a luxury sedan or that it belongs to the Audi. With the line up of all available technologies, the Audi A8 is a true luxury car of style and advanced technology under one roof and also a valuable buy for the customer.

The Audi TT is a two-door compact sports car manufactured by Audi since 1998. It is produced in two generations the first one from 1998 till 2006 and the second one from 2006 till present. It is offered in two body styles a 2+2 Coupe and a two-seat Roadster. The first generation TT was launched as a coupe and a year later it received the Roadster model. The car has two power train options a front wheel drive or Quattro on-demand four wheel drive .Firstly it was equipped with a 1.8L I4 20-valve turbocharged engine with two version a 178 hp (132 kW) and 222 hp (165 kW). The main difference is the bigger turbocharger and a second additional intercooler to the right. Additional engine choice was added also a 3.2 L VR6 engine with 247 hp (184 kW) which was equipped with the Quattro system due to its high power.

In 2005 Audi released a limited edition of the coupe with only 800 cars produced it was called Audi TT Quattro Sport (in Europe it’s known as TT Club Sport) it the same 1.8 L Turbocharged engine as the base models butt with increased power of 237 hp (177 kW) . The car got a reduction in weight of 75 kilograms, and accelerates from 0-62 mph (100 km/h) in 5.9 seconds and has an electronically limited top speed of 250 km/h

Audi A3 is a small family car produced in Europe since 1996 from the German automaker Audi. The car was initially available only with a three-door hatchback presented in front and four wheel drive .The engines were starting from 1.6L I4 to 1.8 L I4 20v Turbo and a diesel engine 1.9L TDI I4.In the late 2000 A3 range got face lifted with new headlights and rear light clusters, other minor cosmetic changes, improved interior and a new six-speed manual gearbox. Audi’s ESP traction control and brake force distribution computer became standard equipment in some countries. In the 2003 Audi launched the second generation of A3 which was designed by Walter de’Silva, it featured a redesigned interior new petrol engines and a standard six-speed manual gearboxes. In mid 2003 new more sportive models were presented a 2.0 Turbo FSI producing 197 hp (147 kW) and a 3.2 VR6 engine with 247 hp (184 kW).In 2004 was presented a 5-door Sportback and in 2008 a Cabriolet .

It is the third generation of the A8, which replaces the 2008 model from early 2010.  It is a luxury sedan four-door (the A7 Sportback is 5 doors) and an alternative to models like the BMW 7 Series , the Jaguar XJ , the Lexus LS , the Mercedes-Benz S-Class or Porsche Panamera , among other models . You can have two bodies, which are distinguished externally by its. It is on sale from € 77,920 (all prices ). Currently is sold with two diesel engines, 250 and 351 bhp and two petrol with 290 and 371 hp, all wheel drive (“Quattro”) and an excellent automatic gearbox with eight relations.

 So far we have proved in depth Diesel 351 hp and as we have measured acceleration capacity is surprisingly high and a low consumption if you drive at a sustained pace. Since speeds more than necessary in almost any condition that can hit the road, maybe a good alternative is the variant 3.0 TDI quattro 250 hp, which also has very good response and is much less expensive. This version 4.2 TDI, which had wheels wider than standard, has surprised us with its agility road of slow, comparable to that of smaller models and weight.

Audi had long threatened to build a supercar to showcase its advance technology. Indeed, in 1991, the company showed two supercars within a couple of months of each other. The Audi Quattro Spyder was the first, shown in September at the Frankfurt show. It was entirely real world, powered by a mid mounted V6 engine, using many components from Audi production cars. A few weeks later, at the Tokyo show, Audi unveiled the Audi Avus Quattro. It was a dramatic design, built around an aluminum spaceframe with polished aluminum panels and a tribute to famous pre war Audi union racers. It was also powered by a conceptual engine made up of three banks of four cylinders. In the end, neither car was made. Audi showed another dramatic aluminum clad supercar concept in 2000. The Rosemeyer, named after one of the Auto Union race drivers was a dramatic, edgy design. But it was forth time lucky with the 2003 Le Mans Quattro concept, which would eventually become the 2007 R8 with only few stylish tweaks. In fact, the styling wasn’t far removed form the 1991 Spyder.

The racy interior was dramatically different to any other Audi, though. This mid engined supercar was built around the same basic aluminum spaceframe chassis as the Lamborghini Galladro (Audi had, by now, become the owner of Lamborghini) and benefited from Quattro four wheel drive. Powered by 4.2 liter engine and promise of bigger engines in the future. The R8 received rave reviews for its poise and place. It may have taken over 16 years, but Audi finally had its own supercar.

Mercedes was not alone when it decided to build a high tech city car in the early 1990s. The Volkswagen Group commissioned a 3litre car and handed responsibility to Audi. A ‘3 liter car is one capable of traveling 100 km on just 3 liter of fuel, 94 mpg in imperial measurements. It was just inspired by an environmental scare as the 1990s dawned a time when the phrase ‘global warming’ was first widely used. Audi decided to make use of its expertise in aerodynamics and lightweight aluminium construction. The main reason for the car’s odd looks was aerodynamics efficiency. Seen from above it has a pronounced teardrop shape. From the side, it has heavily sloping roof and flat sides. The interior was built to the same high standard as Audi’s larger cars, but the interior layout was not as versatile as the Mercedes A-class. It was very light, coming in at as little as 875 kg. Buyers had a choice of a 1.4 three cylinder engine or a 1.4 and 1.6 liter petrol engine. A special version powered by a 1.2 liter which did achieve 94 mpg.

The A2 supermini was first shown as the AL2 concept at the Frankfurt show in 1997, two years ahead of its launch as a production car. By then, however, VW had decided to transfer its efforts on the ‘3 liter’ project to the smaller VW Lupo supermini. Huge strides in diesel engines meant an expensive, super light chassis was not needed. This left the A2 high and dry. It ended up as a beautiful engineered oddball in a market that had forgotten about the idea of global warming.

The term ‘iconic design’ is often misused, but the Audi TT does deserve the accolade. It first appeared as a concept design at the 1995 Frankfurt motor show, having been developed at the VW Group’s California studios. The simple, curved, styling theme was generally thought to have been influenced by pre war German engineering (especially the Auto Union D-Type race cars) and the ‘form follows function’ philosophy of the Banuhaus design school. Perhaps just as impressive was Audi’s achievements in bringing the three door TT to produce, especially as it was mostly based on the MK4 Golf platform. A two door cabrio with the cloth roof was the only other bodystyle produced. Inside, the interior design was just a fresh and simple, marked out by the four large, silver rimmed air vents. The drivetrains were also lifted from the Golf and Audi A3. The entry level engine was a 1.8 liter turbocharged unit in various states of tune from 180 bhp upwards. Top range models were equipped with the notably smooth and powerful 3.2 liter V6 engine. Both engines could be had with a part time four wheel drive system badged Quattro, although it differed from the system used in bigger Audis. Despite eight years of success, the TT almost fell at the first hurdle. Not long after the launch the car was involved in a number of high speed accidents, usually involving a loss of control on bends.

Audi engineers figured that the TT’s smooth rump was to blame, causing rear end lift if the driver lifter off the throttle a high speed or braked, causing the nose to dip. The TT was recalled and fitted with a small boot spoiler (to break the flow of the air over the tail) as well as modifications to the suspension tuning.

By the mid 1990s, Ferdinand Piech had bounced his way from being the chief at Audi to his position as the boss of the truly giant VW Group. His technical genius saw him hatching a plan to build numerous VWs, Audis, Seats and Skodas the four brands in the company portfolio, using the maximum number of shared components. However, despite sharing these parts, the four brands still had to retain distinct identities, something that many doubted they would be able to accomplish. It wasn’t long before, once again, Ferdinand Piech proved his doubters in the VW Company, the industry as a whole, and in certain sections of the motoring press conclusively wrong. The 1997 A6 saw the flowering not only of Piech’s platform strategy, but an amazing rebirth of the genius of German industrial design, echoing and paying homage to all of its grand accomplishments earlier in the century. Under the skin, the A6 shared much with the new VW Passat, and although the suspension systems and floorpan were near identical, the engineering was subtle enough to allow slightly different wheelbases and tracks, sufficient flexibility to give the cars different driving characteristics. For the average buyer, though, it’s the styling both inside and out that gives a car its identity. The A6 was so distinctive that it was a real shock for a lot of people. Audi’s stylists, led by Peter Schreyer, had rediscovered the pre-war German industrial design school.

For many people, the Bauhaus school defined the true nature of industrial design in the 2oth century. The A6’s futuristic rump, with narrow lamp clusters mounted on each corner of the tail and heavily curved roof pillars, was both modern and reminiscent of the art deco and ocean liner style.

Fourteen years after the Quattro, Audi’s technological onslaught resumed with the all aluminum A8 limousine. Because aluminum is less stiff than steel pressing a conventionally engineered body out of aluminum would have proved difficult, if not impossible. With the type of lateral thinking that has come to typify Audi’s approach, the company developed a whole new way of constructing a car. Under the sleek, aluminum paneled skin lies a skeleton of large section aluminum beams, which are both welded and bonded together. Not only does this result in a weight saving of over 300kg compared with a conventional steel bodied car, but it has allowed Audi engineers to use the inherent properties of aluminum to provide class leading safety. The separate chassis/ body construction also made a significant to isolating the vehicle’s passengers from exterior noise. The A8 was also the first Audi to feature the company’s new four link suspension. This design was said to be a big step forward over previous conventional front strut suspension systems, which had been fitted to nearly every front wheel drive car for the previous three decades. The range topping 4.2 Quattro used the Porsche designed Tiptronic automatic transmission, which also offered the driver sequential manual gear selection, unfortunately, the A8 appeared to show every sign of being ahead of its time.

Sales were initially slow, and no other maker has followed Audi’s lead into Aluminium Space Frame (ASF) construction. ASF technology, though, was also used for the A2, Audi’s super economical town car – something which further entrenched the company’s massive technological lead in the field of automobile engineering.
