INTRODUCTION
The Audi A7 Sportback (C8) 45 TFSI S tronic, launched in 2018, is a five-door coupe that blends elegant design with advanced technology. Built on the Volkswagen Group’s MLB Evo platform (shared with models like the Audi A6, A8, and Q7), the C8 A7 represented a significant step forward in terms of interior refinement, driver assistance systems, and overall driving experience. The “45 TFSI” designation indicates the engine output, adhering to Audi’s naming convention, and signifies a 2.0-liter turbocharged four-cylinder engine producing 245 horsepower. The S tronic transmission, a seven-speed dual-clutch unit, was standard, offering quick and smooth gear changes.
Powertrain & Engine Architecture
At the heart of the A7 45 TFSI lies the EA888 2.0-liter inline-four cylinder engine, specifically coded DKNA or DLHA depending on the production year and market. This engine utilizes direct fuel injection, a single turbocharger with an intercooler, and variable valve timing on both the intake and exhaust sides. The turbocharger is a twin-scroll design, enhancing responsiveness and reducing turbo lag. The engine produces 370 Nm (272.9 lb-ft) of torque between 1600 and 4300 rpm, providing strong mid-range acceleration. The S tronic seven-speed dual-clutch transmission is a key component of the powertrain. It offers incredibly fast shifts, both upshifts and downshifts, and contributes to the car’s overall efficiency. The transmission features a wet clutch design for improved cooling and durability. Gear ratios are tuned for a balance of performance and fuel economy, with a relatively tall seventh gear for highway cruising.
Driving Characteristics
The A7 45 TFSI S tronic delivers a refined and comfortable driving experience. While not as overtly sporty as the higher-powered variants (like the 55 TFSI with its V6 engine), it provides ample power for everyday driving and confident overtaking. The S tronic transmission contributes to brisk acceleration, with a 0-60 mph time of around 6.7 seconds. The front-wheel-drive configuration offers good traction in most conditions, although it can exhibit some torque steer under hard acceleration. The steering is precise and well-weighted, providing a connected feel to the road. The suspension, typically featuring independent multi-link setups front and rear, is tuned for comfort, absorbing bumps and imperfections with ease. Compared to the manual transmission options available on some A6 models (which shared the same engine), the S tronic offers smoother and quicker shifts, but some enthusiasts might miss the engagement of a traditional manual gearbox.
Equipment & Trim Levels
The A7 45 TFSI S tronic came well-equipped as standard. Typical features included Audi’s Virtual Cockpit – a fully digital instrument cluster – leather upholstery, three-zone automatic climate control, a 10.1-inch touchscreen infotainment system with MMI Navigation plus, and a suite of driver assistance systems such as Audi Pre Sense basic, lane departure warning, and parking assist. Optional extras included features like a Bang & Olufsen sound system, adaptive cruise control, a head-up display, and matrix LED headlights. Interior trim options varied, with choices in wood, aluminum, and carbon fiber accents. The standard upholstery was typically leather/Alcantara combination, with full leather options available as an upgrade.
Chassis & Braking
The A7 45 TFSI utilizes a sophisticated chassis design. The front suspension features a five-link independent setup, while the rear employs a multi-link configuration. This provides a comfortable ride and precise handling. The braking system consists of ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard, along with electronic brake-force distribution and brake assist. The car’s weight distribution is relatively balanced, contributing to its stable handling characteristics. Stabilizer bars are fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The A7 45 TFSI S tronic was generally well-received by automotive critics. It was praised for its stylish design, luxurious interior, and refined driving experience. The 2.0-liter engine was considered adequate for most drivers, offering a good balance of performance and fuel economy. Compared to the more powerful A7 55 TFSI, the 45 TFSI was seen as a more sensible choice for those prioritizing efficiency and value. Fuel economy figures of around 38 mpg combined were attractive to buyers. Reliability reports have been generally positive, with the EA888 engine proving to be a durable unit. However, like all modern vehicles, preventative maintenance is crucial to avoid potential issues.
Legacy
The Audi A7 Sportback (C8) 45 TFSI S tronic remains a desirable used car option. Its combination of style, technology, and comfort continues to appeal to buyers seeking a premium grand tourer. The EA888 engine, while not known for being the most exciting, is generally reliable and relatively inexpensive to maintain. The S tronic transmission, if properly maintained (regular fluid changes are essential), is also a durable component. As with any used vehicle, a thorough inspection is recommended before purchase, paying particular attention to the condition of the transmission and any potential oil leaks from the engine. The C8 A7 45 TFSI represents a sweet spot in the lineup, offering a compelling blend of luxury and practicality at a more accessible price point than its higher-powered siblings.
