Audi  is a German brand owned by Volkswagen, with a name and history dating back to 1910. The make that we know as Audi was formed in 1969 when VW consolidated several companies into one line. Known as a competitive entrant in the luxury field, Audi specializes in vehicles recognized for attractive styling, good performance and innovative technology. It frequently offers its Quattro all-wheel-drive system as a standard option in all of its models. Luxury models from Audi are known for attractive interiors with detailed finishes and high-quality materials.
Audi differentiates its vehicles by using letters and numbers for their names. Audi base models use an “A” in their names while sportier, more luxurious options take an “S” designation. Audi also offers RennSport models, with fewer luxury touches but higher-level sport performance. These vehicles are labeled “RS.” SUVs and crossovers carry a “Q” in their names while the e-tron (Audi’s EV), R8 and TT are named separately.
Each letter is usually paired with a number, ranging from 3 to 8. Higher numbers typically mean greater power, a larger size or a more luxurious body style; models with higher numbers are generally more costly and considered higher-end.
Like other German luxury models, Audi models tend to have higher levels of depreciation. However, according to Motor Trend, several Audi vehicles have slower depreciation than their luxury import competitors. The Q5 and the Q7 depreciate at slightly over 50% after five years of ownership.
Car buyers looking for bargains can save 50% or more on the cost of even a high-end Audi after three years, however. Audi sports models are particularly likely to show higher depreciation, with the S5 and S6 depreciating over 59% after five years.
Reliability is often a concern for luxury models, especially vehicles like Audis that contain a high level of innovative, precise technology. This kind of high-tech detail can mean that it is easier for something to go wrong. However, according to Consumer Reports, Audi outstrips its German luxury competitors in terms of reliability. It sits at No. 14 on the magazine’s list of the most reliable automakers while Mercedes-Benz comes in at 21 and BMW at 17.

Audi has announced several goals to lower the environmental impact of its manufacturing activities. According to the company, it aims to reduce its impact by 35% per vehicle built by 2025 in comparison to 2010. Audi produces a carbon footprint report annually and has set a goal of CO2-neutral automobile production by 2025. Several of its factories are powered at least partially through waste heat from other industrial facilities nearby. In addition, the company has installed the largest solar-power system in Europe at one of its plants in Hungary, with plans to go online in 2020.
The best-known unique Audi feature is its Quattro all-wheel drive, available on most Audi models. Audi claims that Quattro was the first permanent AWD system developed for passenger cars, and it has been updated repeatedly since its introduction in 1984.

It offers a smartphone-like experience with natural voice control, handwriting recognition and a large dash screen.
Audi’s e-tron SUV was named a leading safety pick by the Insurance Institute of Highway Safety (IIHS), the first fully electric vehicle to be so designated. The IIHS has also given positive safety assessments to most Audi vehicles, naming the A7 and the Q3 as top safety picks. Audis are known for providing strong protection to both drivers and passengers in a crash as well as including technological and autonomous safety features like forward crash prevention and blind-spot detection.
The National Highway Transport Safety Administration (NHTSA) has given high safety rankings to Audi vehicles including the Q5 and the A4 as well. Both received five-star safety ratings from the agency.
What’s next?/Future products
Building on the success of the e-tron, Audi is expected to delve further into the EV market. It has projected the release of 30 new electric vehicles before 2025, 10 featuring hybrid power and 20 full EVs. It will make use of the core platform of the e-tron to introduce multiple sedans and SUVs, which are predicted to hold higher battery capacities and longer ranges. It announced the launch of an 800-volt system, with the higher voltage providing faster charging times, especially as parent company Volkswagen’s Electrify America charging stations roll out in the coming years.
Audi’s concept cars also show a great deal of interest in the power of autonomous, self-driving vehicles. The company has announced a concept car that aims to introduce the “fully autonomous luxury sedan of the future.” It also intends to build on the success of its R8 model, a supercar topping most-wanted lists around the world, by introducing a high-performance sports vehicle with electric power.
