2020 Audi S3 Saloon Review: 0-60 4.6s, Tech, Practicality

The 2020 Audi S3 Saloon stands out as a compact executive sedan that fuses high-revving performance with everyday usability, making it an ideal choice for drivers craving excitement without sacrificing refinement. Powered by a turbocharged 2.0-liter engine producing up to 310 horsepower and 400 Nm of torque, this all-wheel-drive model accelerates from 0-60 mph in around 4.6 seconds while offering a composed ride suitable for long journeys.

Engine and Performance: Turbocharged Thrills

At the heart of the 2020 Audi S3 Saloon lies a potent 2.0-liter TFSI turbocharged four-cylinder engine, delivering 288-310 horsepower depending on the market and tune, paired with 280-400 Nm of torque available from low revs. This setup propels the car to 60 mph in just 4.6 seconds, outpacing its standard A3 sibling by nearly a second, thanks to a quick-shifting seven-speed dual-clutch automatic transmission. No manual option is available, but the automatic’s responsive shifts enhance the driving experience across modes.

The quattro all-wheel-drive system provides exceptional traction, enabling confident launches and stability in wet or slippery conditions. Reviewers praise its ability to fire out of corners with minimal wheelspin, maintaining composure even on off-camber bends. While not as raw as the RS3’s five-cylinder powerhouse, the S3’s engine offers a broad torque band for overtaking ease and a refined growl under hard acceleration.

• Key Performance Specs: 0-60 mph: 4.6-4.7 seconds; Top speed: 155 mph (limited); Torque peak: 1850 rpm.
• Drive modes (Comfort, Auto, Dynamic, Efficiency, Individual) allow tailoring throttle response, steering weight, and exhaust note.
• Magnetic ride adaptive dampers (optional or standard in higher trims) balance sporty firmness with long-distance comfort.

Chassis Dynamics: Balanced and Grippy Handling

The S3 Saloon’s sport-tuned suspension and precise steering deliver sharp, responsive handling without feeling overly harsh. It grips immense cornering speeds, with the quattro system prioritizing front-wheel bias for agile turn-in, subtly rotating the rear under provocation in Sport mode. It’s competent rather than playful, lacking the extreme feedback of rivals like the Golf R or Civic Type R, but excels in real-world point-to-point pace.

Ride quality shines on highways, where the longer saloon wheelbase smooths imperfections better than the Sportback hatch. City driving benefits from light steering in Efficiency mode, while Dynamic mode adds weight for spirited runs. Overall, it walks a fine line between luxury sedan poise and hot hatch agility.

Design and Exterior: Aggressive Yet Elegant

Externally, the 2020 S3 Saloon adopts Audi’s signature sharp lines with sporty enhancements: larger honeycomb grille, aggressive front air intakes, quad exhaust tips, and 19-inch alloys as standard in later updates. Red brake calipers add visual punch, and metallic paint is often included, elevating its premium presence over boy-racer hatches.

Dimensions provide a sleek profile: longer wheelbase than the hatch improves stability and rear legroom, though the low roofline can challenge taller passengers’ headspace. It’s a grown-up hot hatch alternative, blending sophistication with athletic stance.

Interior Quality: Luxurious and Tech-Packed

Step inside, and the S3’s cabin rivals larger Audis with its high build quality, soft-touch materials, and optional carbon-fiber inlays. Quilted Nappa leather S sport seats offer excellent support for cornering and comfort on long drives, with electric adjustments and heating standard. The flat-bottom steering wheel and ambient lighting create a sport-luxury ambiance.

Tech highlights include the Virtual Cockpit digital gauge cluster, 10.1-inch touchscreen infotainment with Apple CarPlay/Android Auto, and optional Bang & Olufsen audio. Dual-zone climate control and a panoramic sunroof enhance daily usability, though piano-black plastics feel dated compared to newer models.

Rear space is tight for adults—best for shorter trips—but the saloon’s trunk swallows 13 carry-on suitcases with seats folded, prioritizing practicality.

• Standard luxuries: Heated seats, wireless charging, rain-sensing wipers.
• Optional upgrades: Matrix LED headlights, head-up display.

Safety and Driver Assistance Features

The 2020 S3 packs advanced safety tech, including adaptive cruise control with stop/go, active lane assist, high-beam assist, and rear parking sensors (recommended due to limited visibility). Pre-sense collision warning and traffic sign recognition add layers of protection, earning strong crash-test ratings in Euro NCAP equivalents.

Fuel Economy and Running Costs

Official figures claim around 32.5 mpg combined with 198 g/km CO2, though real-world tests hover lower due to the thirsty turbo engine. It’s less efficient than the base A3 but competitive in its class. Late-model value packs added features without price hikes, starting around $65,800 plus on-roads in some markets.

Rivals Comparison: How the S3 Stacks Up

The S3 Saloon competes with the BMW M140i, Mercedes-AMG A35, and VW Golf R. It outpaces most in straight-line speed and luxury but trails in raw engagement.

Versus RS3, the S3 is more affordable and civilised, lacking the five-cylinder drama (394 hp, 3.9s 0-60).

Ownership Verdict: Buy If…

The 2020 Audi S3 Saloon earns high marks (7.5/10 from some outlets) for its zesty acceleration, tech-rich cabin, and build quality. It’s perfect for those wanting S4-like luxury in a compact footprint. Drawbacks include tight rear space and moderate efficiency. As it nears end-of-life, used examples offer strong value with added standard kit.
