Engine and Performance Options

The dramatic performance difference between engine options represents the most critical decision for 2019 A3 buyers.

40 TFSI Front-Wheel Drive – 184 Horsepower

The base powertrain delivers adequate but uninspiring performance that may disappoint drivers expecting German driving dynamics.

2.0L Turbo Engine with 221 lb-ft Torque

The detuned EA888 Gen 3B engine prioritizes efficiency over performance, using a smaller turbocharger and conservative tuning^[8]. Key specifications include:

40 TFSI Engine Details:

• Displacement: 1,984cc
• Compression ratio: 11.7:1
• Maximum boost: 11.6 psi
• Power peak: 4,400-6,000 rpm
• Torque peak: 1,600-4,300 rpm

The broad torque curve provides reasonable responsiveness in daily driving, though the modest output struggles when fully loaded or during aggressive acceleration. The engine feels particularly strained above 4,500 rpm where power delivery plateaus noticeably.

FWD Fuel Economy – 27/36 MPG

The efficiency-focused tuning delivers EPA ratings of 27 city/36 highway mpg, with real-world averages around 30-31 mpg^[8]. Premium fuel remains recommended for optimal performance, though many owners report acceptable operation on regular with slightly reduced power. The 13.2-gallon tank provides approximately 400-mile range in mixed driving. This efficiency makes the FWD model attractive for commuters prioritizing fuel costs over performance.

45 TFSI Quattro AWD – 228 Horsepower

The upgraded powertrain transforms the A3 from competent to genuinely engaging, justifying its premium pricing.

2.0L Turbo with 258 lb-ft Torque

The same basic engine receives significant upgrades including a larger turbocharger, upgraded intercooler, and performance calibration^[9]. The result is:

45 TFSI Performance Gains:

• 44 additional horsepower (+24%)
• 37 lb-ft more torque (+17%)
• Improved mid-range response
• Better high-rpm breathing
• Enhanced exhaust note

This configuration matches competitors like the BMW 228i Gran Coupe while delivering the added traction benefits of all-wheel drive.

Quattro Fuel Economy – 22/30 MPG

The performance and all-wheel drive exact an efficiency penalty, with ratings dropping to 22 city/30 highway mpg^[9]. Real-world observations show:

Quattro Fuel Consumption:

• City driving: 20-22 mpg
• Highway cruising: 28-32 mpg
• Aggressive driving: 18-20 mpg
• Annual fuel cost increase: $500-700

Most Quattro buyers accept these trade-offs for the substantial performance and capability improvements.

7-Speed S Tronic DSG Transmission

The dual-clutch transmission delivers quick shifts but requires understanding of its characteristics and maintenance needs. The S tronic uses two separate clutches for odd and even gears, enabling shifts in under 200 milliseconds^[10]. However, common behaviors include:

DSG Characteristics:

• Low-speed hesitation in traffic
• Occasional jerky engagement from stops
• Rolling backward on inclines
• Improved smoothness when warm

These traits are inherent to dual-clutch design rather than defects, though some drivers find them unacceptable compared to traditional automatics.

0-60 Times and Performance Metrics

Acceleration figures highlight the substantial performance gap between variants:

Model	0-60 mph	Quarter Mile	Top Speed
40 TFSI FWD	7.8 seconds	15.9 seconds	130 mph
45 TFSI Quattro	6.0 seconds	14.5 seconds	130 mph (limited)
S3 (reference)	4.7 seconds	13.2 seconds	155 mph (limited)

The nearly two-second difference to 60 mph makes the 45 TFSI feel like an entirely different car, particularly in real-world passing situations.

Reliability and Known Issues

The 2019 A3’s reliability story proves complex, with resolved early-generation issues offset by some persistent problems.

• Heavy steering after restart
• Delayed brake boost
• Rough restarts

Dealers repair this issue free under recall, though parts availability varies. Always verify completion before purchase.

Suspension Noise and Water Pump Issues

Additional concerns include front suspension creaking even at low mileage, typically from strut mounts or control arm bushings. Water pump failures, while less common than early 8V models, still occur around 60,000-80,000 miles at repair costs of $700-1,000. Regular maintenance and prompt attention to unusual noises help prevent major failures.

Interior and Technology Features

The 2019 A3’s cabin balances quality materials with dated technology compared to current standards.

Pop-Up MMI Screen (7.0-inch)

The retractable display represents both a unique feature and potential liability. The motorized 7-inch screen deploys from the dashboard on startup, creating a clean appearance when retracted^[17]. However, the mechanism adds complexity:

Pop-Up Screen Characteristics:

• Takes 3 seconds to deploy/retract
• Can be manually controlled
• Reduces dashboard clutter when hidden
• Subject to mechanical wear

Standard leather upholstery provides appropriate luxury for the segment, with multiple color options including black, beige, and rock gray. The leather quality surpasses mainstream brands though falls short of higher-tier Audis. Three-stage seat heating warms quickly, reaching maximum temperature in under two minutes. The heating elements prove reliable, with few reported failures even at higher mileage.

Panoramic Sunroof

The expansive glass roof comes standard on all trims, unusual for this class^[18]. The front section tilts and slides electronically, featuring:

Sunroof Features:

• Power sunshade
• One-touch operation
• Automatic wind deflector
• Rain-sensing closure
• Pinch protection

Some owners report drain clogs causing water intrusion, requiring periodic cleaning to prevent interior damage.

Cargo Space Limitations

The A3’s compact dimensions result in limited practicality with just 10.6 cubic feet of trunk space^[19]. This compares unfavorably to competitors:

Model	Cargo Capacity
2019 Audi A3	10.6 cu ft
2019 BMW 2 Series	12.0 cu ft
2019 Mercedes CLA	11.9 cu ft
2019 Acura ILX	12.3 cu ft

The small trunk and tight rear seats limit the A3’s family car credentials, making it best suited for couples or small families.

Next Steps

Begin your search by determining whether the base 184-horsepower engine suffices or if the 228-horsepower Quattro’s substantial performance advantage justifies its premium—test drive both as the difference is dramatic. Use NHTSA’s website to verify all recalls have been completed, particularly the critical PODS airbag issue that affects passenger safety. Schedule pre-purchase inspections at Audi specialists who understand DSG transmission evaluation and can scan for stored fault codes.

Request complete maintenance records with particular attention to DSG services at 40,000-mile intervals, as skipped services virtually guarantee expensive failures. Budget for higher ownership costs, including premium fuel, synthetic oil changes, and potential repairs averaging $800-1,200 annually. Compare insurance quotes as the A3’s luxury classification can increase premiums 15-25% versus mainstream sedans.

Consider whether the dated pop-up MMI screen bothers you—spend time with it during test drives as some find it charming while others consider it unacceptable. Evaluate if spending $5,000-8,000 more for a 2022+ model with modern technology makes sense for your situation. Research independent German car specialists in your area who typically charge 30-40% less than dealers while maintaining expertise.

Finally, strongly favor 45 TFSI Quattro S line models despite their premium, as the performance improvement transforms the driving experience and these models retain value approximately 20% better than base variants. According to Autvex market analysis, well-maintained 2019 Quattro models with under 50,000 miles and complete service histories represent the sweet spot for reliability, performance, and value retention in the used luxury compact segment.
