Powertrain & Engine Architecture
At the heart of the 45 TFSI lies the EA888 2.0-liter turbocharged inline-four cylinder engine. Specifically, engine codes DKTB and DNPA were utilized, representing variations within the EA888 family. This engine features direct fuel injection, a single turbocharger with an intercooler, and four valves per cylinder. The direct injection system allows for precise fuel delivery, optimizing combustion efficiency and power output. The turbocharger provides a significant boost in power, delivering 245 horsepower and 272.9 lb-ft of torque. The S tronic seven-speed dual-clutch transmission is standard, offering quick and seamless gear changes. This transmission is known for its efficiency and responsiveness, contributing to the car’s overall performance. The quattro all-wheel-drive system distributes power between the front and rear axles, enhancing traction and stability, particularly in adverse weather conditions.
Driving Characteristics
The 45 TFSI quattro S tronic delivers a refined and engaging driving experience. Acceleration from 0 to 60 mph takes approximately 4.9 seconds, making it a genuinely quick coupe. The S tronic transmission provides rapid shifts, and the quattro system ensures confident handling in various conditions. Compared to the base 40 TFSI, the 45 TFSI offers a noticeable increase in power and torque, resulting in more responsive acceleration and effortless highway cruising. While not as aggressively tuned as the TTS, the 45 TFSI provides ample power for spirited driving. The gear ratios are optimized for both performance and fuel efficiency, with the lower gears providing strong acceleration and the higher gears allowing for relaxed cruising. The steering is precise and well-weighted, providing good feedback to the driver.
Equipment & Trim Levels

Key features included Audi’s Virtual Cockpit – a fully digital instrument cluster – leather upholstery, automatic climate control, and a premium sound system. Standard exterior features included LED headlights, 18-inch alloy wheels, and a rear spoiler. Optional extras included a Bang & Olufsen sound system, navigation system, adaptive cruise control, and various interior trim options. Buyers could also opt for sport seats, upgraded leather packages, and a panoramic sunroof. The interior design is minimalist and driver-focused, with high-quality materials and a clean layout.
Chassis & Braking
The TT Coupe 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 comfort, offering a good compromise for everyday driving. The 45 TFSI model features ventilated disc brakes at the front and solid discs at the rear. The braking system is responsive and provides ample stopping power. Electronic stability control (ESC) and anti-lock braking system (ABS) are standard safety features. The quattro all-wheel-drive system contributes to enhanced stability and braking performance, particularly on slippery surfaces.
