Audi S1

Overview

The Audi S1 represents the performance pinnacle of the original A1 generation, produced from 2013 to 2018 — a period when the appetite for small, powerful hot hatches reached new heights. Built around the same MQB platform as the Volkswagen Polo GTI, the S1 differentiates itself decisively with its 2.0 TFSI turbocharged four-cylinder engine producing 231 hp and 370 Nm, paired exclusively with a 6-speed S tronic dual-clutch gearbox and Audi's quattro permanent all-wheel drive system. This combination enabled a 0–100 km/h time of 5.8 seconds — remarkable performance for a car weighing under 1,300 kg and measuring under 4 metres in length.

The S1's engineering philosophy is one of maximum performance from minimum dimensions. The 2.0 TFSI engine — shared with the Golf GTI in reduced state of tune — produces its peak power across a wide rev range, delivering immediate throttle response that smaller turbocharged units cannot match. The quattro AWD system, developed specifically for the compact S1 platform, routes power to all four wheels through an electronically controlled multi-plate clutch rather than the traditional Torsen mechanical differential — allowing more precise torque distribution and traction optimisation. Sport suspension lowered 15 mm compared to standard A1 models completes a chassis package that remains composed at its limits while offering genuine everyday usability. Available in both 3-door hatchback and 5-door Sportback body styles, the S1 catered to buyers who needed practicality alongside performance.

In the Azerbaijani market, the Audi S1 occupies a unique position as a genuinely rare performance car in the compact class. Unlike the Golf GTI or Polo GTI which are more commonly encountered, the S1's quattro AWD system and Audi premium branding command a significant premium that has preserved its exclusivity. The car's compact dimensions make it ideally suited to urban driving while the quattro traction system provides confidence on Baku's sometimes unpredictable road surfaces. As a discontinued model not replaced in the second-generation A1 lineup, the S1 has appreciating appeal among Audi enthusiasts — the combination of performance, quattro AWD, and compact dimensions will not be repeated in Audi's current portfolio.

• Annual fuel use: 1476 litres
• Annual fuel cost: $959
• Total yearly estimate: $3859
• Monthly average: $322

• The 2.0 TFSI in the S1 is sensitive to oil quality — use only Audi-approved 5W-30 or 5W-40 fully synthetic and change every 5,000 km to protect the turbocharger and timing chain tensioner.
• The S tronic dual-clutch gearbox requires specialist fluid changes every 40,000 km — neglecting this causes clutch judder and rough gear changes that are expensive to rectify.
• The quattro AWD coupling on the S1 is electronically controlled and requires the rear propshaft components to be inspected at 60,000 km intervals to prevent premature bearing wear.

Maintenance & Service in Azerbaijan

• Engine oil and filter change every 5,000 km with 5W-30 or 5W-40 Audi-approved fully synthetic — the 2.0 TFSI turbo requires clean oil for both the turbocharger and the timing chain tensioner to function correctly.
• Spark plug replacement every 30,000 km — the high-compression turbocharged direct-injection four-cylinder is sensitive to worn plugs; misfires under boost cause catalytic converter damage if left unresolved.
• S tronic dual-clutch transmission fluid service every 40,000 km — the wet-clutch DSG requires clean transmission fluid to maintain smooth gear changes and prevent clutch judder on low-speed manoeuvres.
• Brake fluid replacement every 2 years regardless of mileage — the small but capable brake system heats fluid significantly during spirited driving; degraded fluid causes spongy pedal feel under repeated hard braking.
• quattro rear coupling inspection every 60,000 km — check the propshaft centre bearing, rear differential seals, and coupling unit for leaks; early intervention prevents costly AWD system repairs.

Used S1 Buying Checklist

• Test all four gears across the rev range — the S tronic should shift crisply without hesitation or hunting; any delay or shudder on gear engagement indicates worn clutch packs requiring specialist attention.
• Check for quattro AWD engagement during a controlled corner exit — both driven wheels should pull evenly without wheel spin; uneven traction suggests a worn rear coupling or differential issue.
• Inspect the 2.0 TFSI for turbocharger boost consistency — the engine should pull strongly from 2,000 rpm to the 6,500 rpm red line without flat spots; hesitation under boost indicates a boost leak or failing turbo.
• Verify the sport suspension is functioning correctly — the S1 rides 15 mm lower than standard; any corner sitting noticeably higher suggests a failing spring or worn damper that will affect handling balance.
• Check for DSG software updates — many S1 examples benefit from the latest S tronic calibration software from Audi; outdated software can cause gear selection delays and shift quality issues.
• Inspect the timing chain tensioner for slack — the 2.0 TFSI has a known history of tensioner wear on higher-mileage examples; a rattling noise on cold start is the primary warning sign.

S1 FAQ — Azerbaijan Buyers

Should You Buy the Audi S1?

The S1 makes its case through a combination that is simply unavailable elsewhere in the current market: quattro all-wheel drive in a sub-4-metre hatchback body with 231 hp from a thoroughly engineered 2.0 TFSI engine. The fact that Audi chose not to continue the S1 nameplate into the second-generation A1 only enhances its standing as a collector's item among Audi enthusiasts. In practical terms, it is fast enough to embarrass considerably larger cars in real-world conditions, the quattro traction makes it genuinely confidence-inspiring in wet weather, and its compact dimensions make it one of the easiest high-performance cars to drive every day. The trade-off is a discontinuted model with potentially longer parts lead times and a premium price that reflects its rarity. For buyers who want something genuinely special in the compact class — a car that cannot be replicated by any current Audi product — the S1 is a compelling choice.
