Powertrain & Engine Architecture
The heart of the A4 40 TFSI is the EA888 2.0-liter inline-four cylinder engine. Specifically, the DKYA and DLVA engine codes were commonly found in this variant. This engine utilizes direct fuel injection and a single turbocharger with an intercooler to deliver a responsive and efficient driving experience. The engine’s design incorporates features like variable valve timing on both intake and exhaust camshafts, optimizing performance across the rev range. The 6-speed manual transmission was standard, providing precise gear changes and a more engaging driving experience. The engine’s output of 190 horsepower and 320 Nm (236 lb-ft) of torque allows for brisk acceleration and confident highway cruising.
Driving Characteristics
The A4 40 TFSI with the manual transmission offers a balanced driving experience. Acceleration from 0-60 mph takes approximately 6.8 seconds, making it competitive within its class. The turbocharger provides a noticeable boost in power, particularly in the mid-range, allowing for effortless overtaking. The manual gearbox is well-matched to the engine’s characteristics, with smooth shifts and a relatively short throw. Compared to the more powerful 45 TFSI, the 40 TFSI feels less urgent, but it offers a more fuel-efficient and accessible driving experience. The suspension provides a comfortable ride, absorbing bumps and imperfections in the road while maintaining good body control.
Equipment & Trim Levels
The A4 40 TFSI typically came standard with features such as Audi’s MMI infotainment system with a 7-inch display, automatic climate control, leather-wrapped steering wheel, and cloth upholstery. Optional extras included a larger MMI display, navigation system, a premium sound system, leather seats, and a suite of driver-assistance features like adaptive cruise control and lane departure warning. Trim levels varied by market, but generally offered packages that bundled popular options together. The interior design was characterized by Audi’s signature minimalist aesthetic, with high-quality materials and a focus on ergonomics.
Chassis & Braking
The A4 40 TFSI utilizes a front-wheel-drive layout with an independent multi-link suspension at both the front and rear. This suspension setup provides a good balance of comfort and handling. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard, enhancing safety and stability during emergency braking. The steering is electrically assisted, offering precise and responsive control.
Market Reception & Comparison
The Audi A4 40 TFSI was generally well-received by automotive critics. It was praised for its refined interior, comfortable ride, and efficient engine. However, some reviewers noted that the base engine could feel a bit underpowered compared to rivals. In terms of fuel economy, the 40 TFSI offered competitive figures, achieving around 39-42 mpg on the highway. Compared to the A4 35 TFSI, the 40 TFSI offered a noticeable performance upgrade, while the A4 45 TFSI provided even more power but at a higher price point.
Legacy
The EA888 engine family, including the 2.0-liter unit found in the A4 40 TFSI, has proven to be relatively reliable over the long term. However, like any turbocharged engine, it’s important to adhere to recommended maintenance schedules, including regular oil changes and inspections. Common issues reported with this engine include carbon buildup on the intake valves, which can affect performance. The A4 B9 generation, including the 40 TFSI variant, remains a popular choice in the used car market due to its blend of luxury, performance, and technology. Well-maintained examples continue to offer a compelling value proposition for buyers seeking a premium compact executive car.
