Powertrain & Engine Architecture
The heart of the A3 45 TFSI e is the EA211 evo2 1.5-liter inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and a single turbocharger with intercooling to produce 177 horsepower at 5000-6000 rpm and 250 Nm (184.39 lb.-ft.) of torque between 1500-4000 rpm. The engine features a relatively high compression ratio of 11.5:1, contributing to its efficiency. Integrated with this engine is a 116 hp electric motor, powered by a 19.7 kWh (usable) lithium-ion battery pack. The battery is positioned under the rear seats and floor, minimizing impact on cabin space. The electric motor is a synchronous design, providing instant torque and assisting the gasoline engine. The combined system output reaches 272 hp and 400 Nm (295.02 lb.-ft.) of torque. Power is delivered to the front wheels via a six-speed S tronic dual-clutch automatic transmission, known for its quick and smooth shifts. This transmission is specifically calibrated to work seamlessly with both the gasoline engine and the electric motor.
Driving Characteristics
The 45 TFSI e offers a distinct driving experience compared to other A3 variants. In electric-only mode, the car provides near-silent acceleration and a range of up to 135 km (83.89 miles) on the WLTP cycle. The instant torque from the electric motor makes for brisk acceleration in urban environments. When the battery is depleted or when more power is demanded, the gasoline engine seamlessly kicks in. The combined power output delivers a 0-60 mph time of around 6 seconds, making it one of the quicker A3 models. The S tronic transmission contributes to responsive gear changes, enhancing the overall driving experience. Compared to the 1.5-liter non-hybrid A3, the 45 TFSI e feels more powerful and refined. Compared to higher-performance models like the S3, it offers a balance between efficiency and performance, prioritizing fuel economy and reduced emissions without sacrificing a sporty feel.
Equipment & Trim Levels
The 45 TFSI e typically comes with a generous level of standard equipment. This includes Audi’s Virtual Cockpit digital instrument cluster, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a suite of advanced driver-assistance systems such as lane departure warning and automatic emergency braking. Interior upholstery is typically a combination of cloth and leatherette, with options for full leather available. Trim levels often include features like sport seats, a panoramic sunroof, and premium audio systems. Specific options packages can add features like adaptive cruise control, a head-up display, and matrix LED headlights.
Chassis & Braking
The A3 Sportback 45 TFSI e utilizes an independent suspension setup, with a McPherson strut front suspension and a multi-link rear suspension. This configuration provides a comfortable ride while maintaining good handling characteristics. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The braking system consists of ventilated front discs and solid rear discs. ABS (Anti-lock Braking System) is standard, along with electronic brake-force distribution and brake assist. The added weight of the battery pack is compensated for by the suspension tuning, ensuring a balanced and controlled driving experience.
Market Reception & Comparison
The Audi A3 45 TFSI e has been generally well-received by automotive critics. It’s praised for its fuel efficiency, smooth acceleration, and comfortable ride. The electric-only range is considered competitive within its class. Compared to other A3 variants, the 45 TFSI e offers a compelling alternative for buyers prioritizing environmental consciousness and lower running costs. However, the higher purchase price compared to non-hybrid models is a potential drawback. Fuel economy is significantly better than the standard 1.5 TFSI, and reliability is expected to be comparable, although the added complexity of the hybrid system introduces potential new failure points.
Legacy
The A3 45 TFSI e represents a significant step in Audi’s transition towards electrification. The EA211 evo2 engine paired with the electric motor and S tronic transmission has proven to be a reliable and efficient powertrain. As the used car market matures, these models are expected to hold their value well, particularly among buyers seeking a fuel-efficient and technologically advanced compact hatchback. The long-term durability of the battery pack will be a key factor in determining the overall reliability and resale value of these vehicles.
