About This 2024 Audi A4 S Line 45 TFSI Premium Plus

The 2024 Audi A4 represents one of the final expressions of a generation that has consistently set the benchmark for compact luxury sedans. The S Line trim gives this car an aggressive, sport-forward aesthetic — sharpened front fascia, distinctive side sills, and an interior upgraded with sportier appointments that make every drive feel intentional.

For buyers in Costa Mesa and the broader Orange County area, this is the sweet spot: modern luxury, proven reliability, and a price point that makes the math undeniably attractive.

The S Line 45 TFSI Premium Plus sits near the top of the A4 trim hierarchy, meaning this vehicle was specified with a long list of features from the factory. You're not buying a stripped-down base model dressed up with a spoiler — this is the genuine premium experience Audi intended for its most discerning customers.

2024 Audi A4 Performance and Engine

Turbocharged 2.0-Liter Four-Cylinder Power

Under the hood sits Audi's refined 2.0-liter turbocharged four-cylinder engine — the 45 TFSI designation indicating the higher state of tune in this configuration, producing a strong 261 horsepower and 273 lb-ft of torque. In real-world driving, that means confident acceleration from a stoplight, effortless merging on the 405 or the 55 freeway, and enough punch to make spirited canyon runs genuinely enjoyable.
 

7-Speed S Tronic Dual-Clutch Transmission

Power is channeled through Audi's 7-speed S Tronic dual-clutch automatic transmission — a gearbox that delivers lightning-fast, seamless shifts while remaining smooth and unobtrusive in everyday traffic. Paired with Audi's legendary Quattro all-wheel drive system, this A4 delivers sure-footed traction in virtually any condition, from coastal morning fog along Pacific Coast Highway to the occasional wet winter road in Southern California.

Audi A4 Features and Interior

What the S Line Premium Plus Trim Includes

The Premium Plus trim level is where Audi's feature set becomes genuinely impressive. Buyers can expect a virtual cockpit digital instrument cluster, Audi's MMI infotainment system with a large central touchscreen, wireless Apple CarPlay and Android Auto integration, and a premium sound system. The S Line interior brings sport seats with enhanced bolstering, S Line badging, aluminum inlays, and a flat-bottomed sport steering wheel that reinforces the performance character of the exterior.

Safety and driver assistance technology on this trim typically includes lane departure warning, forward collision warning with automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, and adaptive cruise control — a suite that makes long drives on the I-5 or daily commuting through Orange County dramatically less stressful. The interior quality, material fit and finish, and overall sense of occasion inside an Audi A4 is something that competitors in this class have consistently struggled to match.

Audi A4 Reliability and Ownership

The 2024 Audi A4 benefits from years of refinement and a platform that Audi has developed into one of the most dependable in its segment. Consumer satisfaction rates for A4 owners are consistently high, with drivers praising the long-term build quality, the way the car holds up aesthetically over time, and the absence of significant mechanical drama when maintenance schedules are followed. The 2.0 TFSI engine in this generation is a robust, well-understood unit that responds well to regular oil changes and standard upkeep.

At 48,000 miles, this A4 has cleared its earliest service intervals and any factory break-in quirks. Audi's Quattro AWD system in this application is mechanically straightforward and doesn't carry the maintenance burden that some older or more complex all-wheel drive setups demand. For Orange County buyers who want luxury without the ownership anxiety, the 2024 A4 S Line is a well-proven choice.

How many miles is too many for a used 2024 Audi A4?

For a well-maintained Audi A4, 48,000 miles is still well within the early-to-mid life of the vehicle. The 2.0 TFSI engine and S Tronic transmission are both designed to go well past 150,000 miles with proper care. 48,000 miles on a 2024 model means this car is still relatively young and has benefited from recent engineering and manufacturing standards. A pre-purchase inspection will confirm condition, but mileage alone should not be a concern at this level.
 

What does the S Line 45 TFSI Premium Plus trim include?

The S Line designation adds sport-tuned aesthetics including distinctive bumpers, side skirts, sport seats, a flat-bottomed steering wheel, and S Line interior trim. The 45 TFSI refers to the higher-output 2.0-liter turbocharged engine. Premium Plus adds technology and comfort upgrades over the base Premium trim, typically including the virtual cockpit, premium audio, advanced driver assistance systems, blind-spot monitoring, and enhanced connectivity features.
 

Does the 2024 Audi A4 have all-wheel drive?

Yes. This 2024 Audi A4 S Line 45 TFSI comes equipped with Audi's Quattro all-wheel drive system as standard.

Is the 7-speed S Tronic a reliable transmission?

Yes. Audi's S Tronic dual-clutch transmission has matured significantly over successive generations and is now considered one of the more dependable units in the luxury segment.
