Technical Specifications

INTRODUCTION

The Audi A7 Sportback (C8) 45 TFSI, launched in 2020, is a five-door liftback coupe that forms part of the third generation (C8) A7 series. Positioned within Audi’s luxury range, it builds upon the success of the previous A7 models, offering a more refined and technologically advanced package. The “45 TFSI” designation indicates the engine output level, signifying a 2.0-liter turbocharged four-cylinder engine producing 265 horsepower. The inclusion of “Mild Hybrid” denotes the integration of a 48-volt mild-hybrid system, contributing to improved fuel efficiency and smoother operation. The “quattro ultra” system signifies Audi’s on-demand all-wheel-drive technology, enhancing traction and stability. The S tronic transmission is a seven-speed dual-clutch unit known for its rapid and seamless gear changes.

Powertrain & Engine Architecture

At the heart of the A7 45 TFSI lies the EA888 2.0-liter turbocharged four-cylinder engine, specifically coded DMTA or DPAA depending on the production year and market. This engine utilizes direct fuel injection, delivering fuel directly into the combustion chamber for improved efficiency and power. The engine features a single twin-scroll turbocharger with an intercooler, maximizing boost pressure and minimizing turbo lag. The valvetrain employs a Dual Overhead Camshaft (DOHC) configuration with four valves per cylinder, optimizing airflow and combustion. The mild-hybrid system incorporates a belt starter generator (BSG) and a small lithium-ion battery. The BSG allows for extended start-stop operation, regenerative braking, and a slight power boost during acceleration. The seven-speed S tronic dual-clutch transmission provides incredibly quick and smooth gear changes, contributing to both performance and efficiency. This transmission features two separate clutches, one for odd gears and one for even gears, allowing for pre-selection of the next gear for near-instantaneous shifts.

Driving Characteristics

The A7 45 TFSI delivers a refined and comfortable driving experience. While not as overtly sporty as the higher-output variants, the 265 hp engine provides ample power for everyday driving and confident highway cruising. Acceleration from 0-60 mph takes approximately 5.9 seconds. The S tronic transmission contributes to a responsive feel, with quick and precise gear changes. The quattro ultra all-wheel-drive system provides excellent traction in various conditions, automatically distributing torque between the front and rear axles as needed. The suspension is tuned for comfort, absorbing bumps and imperfections in the road effectively. Compared to the more powerful 55 TFSI model, the 45 TFSI offers a slightly softer ride and a more relaxed driving experience. The gear ratios are optimized for a balance of acceleration and fuel economy, with a relatively tall seventh gear for efficient highway cruising.

Equipment & Trim Levels

The A7 45 TFSI typically came well-equipped as standard. Common features included Audi’s Virtual Cockpit digital instrument cluster, a 10.1-inch touchscreen infotainment system with MMI Navigation plus, leather upholstery, three-zone automatic climate control, and a suite of driver-assistance systems such as lane departure warning and automatic emergency braking. Optional extras included features like a Bang & Olufsen sound system, adaptive cruise control, a head-up display, and various interior trim upgrades. The interior design is characterized by its minimalist aesthetic and high-quality materials. Dashboard layout is clean and modern, with a focus on intuitive controls.

Chassis & Braking

The A7 45 TFSI utilizes an independent multi-link suspension system at both the front and rear axles, providing a comfortable and controlled ride. The suspension geometry is optimized for stability and handling. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. Anti-lock Braking System (ABS) and Electronic Stability Control (ESC) are standard features. The steering system is an electric power-assisted rack and pinion system, offering precise and responsive steering feel.

Market Reception & Comparison

The Audi A7 45 TFSI was generally well-received by automotive critics. It was praised for its stylish design, luxurious interior, and refined driving experience. The fuel economy of 7.4-8.3 l/100 km (28.3-31.8 US mpg) was considered competitive for its class. Compared to the 55 TFSI variant, the 45 TFSI offered a more affordable entry point into the A7 range, while still providing a high level of luxury and performance. Some critics noted that the 2.0-liter engine could feel slightly strained during hard acceleration, particularly when fully loaded. However, the mild-hybrid system helped to mitigate this issue by providing a temporary power boost.

Legacy

The EA888 2.0-liter turbocharged engine used in the A7 45 TFSI has proven to be a reliable and durable powertrain when properly maintained. The S tronic transmission is also generally considered to be reliable, although regular servicing is essential. In the used car market, the A7 45 TFSI represents a good value proposition, offering a blend of luxury, performance, and efficiency at a competitive price point. Its sophisticated technology and stylish design continue to appeal to buyers seeking a premium grand tourer.
