"Audi was started by August Horch in 1899. Name got picked as such because it was the Latin translation of his name, ""hark"". Three other German car makers joined Audi to form the Auto Union in 1932. Each company kept their own identity and is symbolized by the now famous interlocking rings. Audi focused of performance and luxury cars. A regrouping was forced after World War II and Audi was bought by Volkswagen in 1964. These two now share the technological innovation that was developed in Audi's lab back in Ingolstadt. Today, Audi is renown for its quality engineering, technological advancements, and emphasis on comfort and luxury enhancing the driving experience. Several innovations have been introduced over the years, such as the four-stroke engine (the Audi 72 in 1965) and the quattro technology that has been highly touted about. What this all-wheel drive system does is distribute power evenly over all four wheels for an increased traction and stability. Originally only in larger vehicles and thought too heavy for a race car, it made its debut in a car circuit in 1980. It later appeared in the Audi 80 (in 1982) and later on it was offered across the entire Audi linep (by 1984). Quattro remains a premier Audi feature as it performs better than most SUV's in the snow and ice. Audi cars have made their mark by installing standard features that are usually options in other cars, such as cruise control, power windows and locks, leather seats and sunroof. Also, they have always offered high-end comfort and elegance along with superb craftsmanship and safety. The 1968 Audi 100 was the first modern car and luxury sedans have been associated with the Audi name since. A turbo version of the Audi 100 was the Audi 200. Audi 80 and 90 were ""economy"" versions of the 100 and 200. The A8 began as the V8 and was the highest-end luxury sedan. All these brand numbers received a massive overhaul in 1996. It included restyling, more standard features and new names: A4, A6, and A8. Each progressive number indicated a slightly larger and bigger size engine. The Avant station wagons were added to these lineups as a recognition of the cargo needs of families. And as recognition for the need of fun, the convertible option in the A4 (Cabriolet) appeared in 2003. The A6 and A8 have their sports-performance counterparts in the S6 and S8, which offer firmer suspensions, supportive seats and a V and V10 engine respectively. The RS6 provides the ultimate in sports performance tearing it up with a turbo V10 engine that hits 550-hp. Before 2001, Audi did not have an SUV offering. Then came the allroad quattro crossover that was part station wagon, part SUV. Although i was never popular in the U.S., perhaps because people just weren't ready for it. In 2006, a new crossover vehicle appeared on scene. It was the stylish and elegant A3. The Audi SUV, the full size luxury Q7 debuted also in 2006. It has not received great reviews, specially for off-road handling. One of Audi's coolest looking cars hitting the road is the Audi TT, all rounded muscles and bundled energy. Everyone was surprised with Audi's influential TT in 1998. Its hidden bumpers, rounded dome and aerodynamic design was a complete rethink of how cars should look. The TT re-energized the Audi name and has been a big influence on car design ever since. The aluminum body 2008 TT is highly anticipated. And Audi isn't stopping there. The yet to be released R8 promises a mid-mounted engine and some heart-stopping action. Designs for a lightweight aluminum AL2 sports wagon are still in the concept stage. Audi continues to deliver technological innovation to produce cars that not only drive well, are handled confidently, and offer maximum stability and safety, but that are also luxuriously comfortable and combine elegance and cool ."
