INTRODUCTION
The 2018-2023 Audi TT Coupe 45 TFSI S tronic represents a refinement of the 8S generation, offering a compelling blend of performance, style, and technology. The facelift brought subtle but noticeable changes to the exterior, including revised headlights and grille, along with interior upgrades focused on the infotainment system. This variant, powered by a 2.0-liter turbocharged four-cylinder engine producing 245 horsepower, occupied a sweet spot in the TT lineup, providing a noticeable step up in performance over the entry-level 40 TFSI while remaining more affordable and practical than the high-performance TTS. The S tronic dual-clutch transmission was standard, offering quick and precise gear changes.
Powertrain & Engine Architecture
At the heart of the 45 TFSI lies the EA888 2.0-liter inline-four cylinder engine, specifically coded DKTB or DNPA depending on the exact production year and market. This engine utilizes direct fuel injection and a single turbocharger with an intercooler to deliver its power. The engine benefits from Audi’s variable valve timing system (Audi Valvelift) on both the intake and exhaust sides, optimizing performance and efficiency across the rev range. The S tronic 7-speed dual-clutch transmission is a key component of this powertrain. It offers incredibly fast shifts and contributes to the car’s overall responsiveness. Unlike a traditional automatic, the S tronic doesn’t have a torque converter, resulting in a more direct connection between the engine and the wheels. The transmission features both automatic and manual shift modes, allowing the driver to tailor the driving experience.
Driving Characteristics
The 45 TFSI S tronic delivers a noticeably more engaging driving experience than the base 40 TFSI. The increased horsepower and torque, combined with the quick-shifting S tronic transmission, result in a 0-60 mph time of around 5.5 seconds. The engine provides a broad torque curve, making it responsive in everyday driving situations. While front-wheel drive, the electronic stability control system and the S tronic’s launch control feature help to minimize wheelspin during acceleration. The gear ratios are tuned for a balance between acceleration and fuel efficiency. Compared to the manual transmission option (available in some markets), the S tronic offers smoother and faster shifts, but some purists might miss the direct engagement of a traditional manual gearbox. The 45 TFSI feels confident and composed on winding roads, offering a good level of grip and predictable handling.
Equipment & Trim Levels
The 45 TFSI typically came well-equipped as standard. Key features included Audi’s Virtual Cockpit – a fully digital instrument cluster – leather upholstery, automatic climate control, and a premium sound system. Exterior features often included LED headlights, 18-inch alloy wheels, and a rear spoiler. Optional extras included a panoramic sunroof, upgraded leather packages, a navigation system, and advanced driver-assistance systems such as adaptive cruise control and blind-spot monitoring. The interior design was minimalist and driver-focused, with high-quality materials and a clean layout. The TT’s signature circular air vents were a prominent design element.
Chassis & Braking
The 45 TFSI utilizes a McPherson strut front suspension and a multi-link rear suspension, providing a comfortable yet sporty ride. The suspension is tuned to balance handling and ride quality. The car features ventilated front disc brakes and solid rear discs. ABS (Anti-lock Braking System) is standard, along with electronic stability control. The steering is electrically assisted, providing precise and responsive steering feel. The 45 TFSI’s chassis is relatively lightweight, contributing to its agile handling characteristics. The standard tire size is 225/50 R17, although larger wheels and tires were available as options.
Market Reception & Comparison
The Audi TT Coupe 45 TFSI S tronic was generally well-received by automotive critics. It was praised for its stylish design, engaging driving dynamics, and high-quality interior. Critics noted that the 45 TFSI offered a significant performance upgrade over the 40 TFSI without a substantial price increase. Compared to the TTS, the 45 TFSI offered a more accessible price point and slightly better fuel economy. Fuel economy figures typically ranged from 26 to 33 mpg combined, depending on driving conditions. Reliability was generally good, although some owners reported minor issues with the infotainment system.
Legacy
The Audi TT Coupe 45 TFSI S tronic has established itself as a desirable used car. Its combination of style, performance, and technology continues to appeal to buyers. The EA888 engine is known for its durability and tunability, making it a popular choice for enthusiasts. The S tronic transmission, while requiring more diligent maintenance than a traditional automatic, is generally reliable when properly serviced. As the TT generation has aged, these models represent a good value proposition for those seeking a premium sports coupe experience. The 8S TT, and particularly the 45 TFSI variant, is likely to remain a sought-after model in the used car market for years to come.
