This guide digs deep into the luxury car market. We’ll explore their rich histories, trim levels, reliability and maintenance costs, and a lot more. With this info, you’ll easily find the car that suits your needs, with Carplus helping you out.


Mercedes-Benz started with Karl Benz’s innovative internal combustion engine in 1886, financed by Bertha Benz’s dowry. Roughly at the same time, Gottlieb Daimler and Wilhelm Maybach converted a stagecoach into a petrol-engine vehicle. Together, they founded Benz & Cie, and by 1900, it became the world’s largest automaker. In 1901, “Mercedes” was registered as a trademark, and the first Mercedes-Benz cars were made in 1926.

Audi’s story starts in the early 20th century with engineer August Horch founding Horch and Audiwerke. The first model—Type A model—had a 2,612 cc inline-four engine. They later released models with larger engines, which did well even as sports cars in competitions. In 1924, Audi introduced its first six-cylinder model, the Type M. Audi’s modern era began in the 1960s when Volkswagen bought Auto Union from Daimler-Benz.

Trim Levels

Once you’ve picked your model, you’ll need to select from various trim levels. Each trim offers different features and allows you to customise how equipped you want your car to be.

Audi Trims

The SE trim level trim is Audi’s basic option, including essentials like air conditioning and parking sensors. Moving up, the Sport trim introduces larger alloys for a specific look from sportier models. The S-Line trim, traditionally considered top-tier, has larger alloys, sportier styling in bumpers, lowered suspension, LED headlights, and interior enhancements like aluminium detailing, comparable to BMW’s M Sport models.

For a more aggressive look, the Black Edition takes the S-Line models and adds gloss black accents, dark alloy upgraded wheels, and sometimes upgraded stereo systems. S models combine performance and style with all-wheel drive, powerful turbocharged engines, and quick-shifting dual-clutch gearboxes.

Audi’s RS models are the ultimate in performance — increased power, lighter weight, improved suspension, and wider wheels.

Mercedes Trims

The SE is the starting model, with 16-inch alloy wheels, LED daytime running lights, heated front seats, keyless entry and start, and the latest MBUX infotainment system featuring two 7-inch displays.

The Sport model adds 17-inch alloy wheels, LED high-performance headlights, and Thermotronic auto climate control. The Sport Executive Edition enhances the experience with a larger touchscreen, privacy glass, sports seats, and rear parking sensors.

The Executive Edition features iconic AMG styling, 18-inch AMG-style alloy wheels, and a 10.25-inch touchscreen with smartphone integration. The Premium Edition adds a 10.25-inch digital driver display and keyless entry. Finally, the Premium Plus Edition includes advanced lighting and upgraded safety tech like a panoramic glass roof and auto traffic sign recognition.

Design and Styling

Audi exterior

Audi chooses sleek and timeless styling, often with a uniform look across many models.

Mercedes exterior

Mercedes-Benz keeps things simple and welcoming in its exterior design. They choose roundness, proportions, and stance while steering clear of extra frills. This gives their cars a classic charm, like the iconic 300SL.

Audi interior

Audi’s interior design features minimalist dashboards, premium materials, and comfortable seating options. The overall atmosphere is sophisticated and premium, although it leans towards a sporty feel rather than pure comfort.

Mercedes interior

Mercedes excels in creating comfortable interior cabin space. From the GLE and GLS to the E-Class and luxurious S-Class, they set high standards across the industry. The quality and design of their interiors are top-notch, and some models are considered the best in the business.

Technology and Infotainment

Audi’s tech lineup includes the MMI infotainment system, which lets you control navigation and Bluetooth. They also have the Virtual Cockpit, a digital display replacing traditional dials. Audi Connect offers real-time updates on traffic and weather and allows you to use smartphone apps in the car. Some critics say Audi’s graphics could be better, but features like Audi Connect make driving more enjoyable.

Mercedes’ MBUX system has excellent voice control called Hey Mercedes, which doesn’t need Siri or Google Assistant. In smaller Mercedes models like the A-Class, you get two 10.25-inch screens. In bigger models like the E-Class, each screen is 12.3 inches. The screens have regular maps, Google or Apple Maps from your phone, and an augmented reality feature.


Audis are generally quiet, particularly in terms of wind and tyre noise. However, performance models may have more noticeable engine noise, which makes for a sportier driving experience. Despite this, the ride strikes a good balance between firmness and comfort and handles bumps smoothly without excessive body movements.

Audi’s interiors maintain a consistent, high-quality feel. The design is smart and functional rather than flashy, and the materials and surfaces used are top-notch.

In collaboration with Kingsman Concepts, Mercedes made their cars easy to use by placing controls and interfaces where they’re easy to reach. The driver and passengers can interact with the car smoothly and enjoy a comfy, personalised experience that’s really luxurious. Even with big 20-inch wheels, the ride stays smooth, even on rough roads. The cabin is also quiet, with minimal wind or tyre noise. But it doesn’t feel as isolating as the extremely refined Audi A4.

Brand Image and Perception

Consumers’ views of brands strongly influence what they buy and how they want to appear. So, choosing a brand that matches the image and lifestyle you want to project is instrumental for making a statement and showing a particular identity.

When it comes to Mercedes’ image and perception, it’s associated with a flashy, bold, and luxurious vibe, which appeals to a more mature audience. Audi is seen as representing sophistication, advanced technology, and a trendy urban vibe, which attracts a younger audience.

Environmental Concerns and Sustainability

Audi prioritises sustainability in its operations through:

  • Developing electric and hybrid high-quality vehicles like the Audi e-tron series.
  • Transitioning to sustainable energy sources in production to lower reliance on non-renewable fuels.
  • Researching eco-conscious materials like recycled and plant-based options for making vehicles.
  • Encouraging recycling practices and crafting vehicles for simplified disassembly.
  • Using lightweight components, such as aluminium and carbon fibre, to enhance both fuel efficiency and overall performance.

Here are some key initiatives Mercedes-Benz is actively pursuing:

  • New partnerships to develop and manufacture advanced battery cells in Europe.
  • Research of environmentally friendly materials to strike a balance between sustainability and luxury. For example, they are exploring the use of UBQ plastic, derived from household waste, in the EQS and EQE.
  • Upholstery fabrics crafted entirely or partially from recycled PET bottles.
  • Steel with a reduced carbon footprint integrated into their manufacturing processes.
  • Structural castings made from die-cast alloys that incorporate up to 100% recycled aluminium scrap in the Mercedes-AMG SL.


The difference between top luxury German brands mostly boils down to the finer details and personal preference. Audi and Mercedes-Benz are neck and neck in terms of most parameters.

Audi is a great choice for those looking to save money without compromising on features, safety, or performance. It shines in the small car and sports car categories. Mercedes, on the flip side, is famous for its luxurious interiors and gives most Audi vehicles a run for its money in most segments, especially larger vehicles.

In some cases, opting for a Mercedes over an Audi is the better choice. However, be sure to research the specific models you’re interested in because manufacturers can have hit-and-miss models. Once you’ve made your decision, turn to Carplus for the next step in financing!
