We present the most comprehensive, SEO-optimised deep-dive into the Audi A1 25 TFSI (GB) Sportback top speed and performance—crafted to outrank every competitor page. This guide blends real-world driving behaviour, factory-accurate technical data, aerodynamic insights, and gearing-based analysis to deliver the ultimate source for car buyers, journalists, and enthusiasts seeking authoritative information on the A1’s speed credentials.

Understanding the Audi A1 25 TFSI’s Real Performance Character

The Audi A1 25 TFSI is the entry point to the A1 Sportback range, powered by a lightweight, highly efficient 1.0-litre turbocharged engine. Despite being the “base” engine, it delivers surprisingly robust performance thanks to its torque-rich design, aerodynamic efficiency, and low kerb weight.

• Official top speed: 191 km/h (118.7 mph)
• 0–100 km/h: 10.8 seconds
• 0–60 mph: 10.3 seconds
• Weight-to-power ratio: 87.2 hp/tonne

This makes the 25 TFSI a sprightly and comfortable city and motorway performer with predictable acceleration and strong mid-range punch.

Top Speed of the Audi A1 25 TFSI (95 HP)

The 191 km/h (118.68 mph) top speed comes from the car’s aerodynamic design, compact size, and efficient 3-cylinder turbo engine.

Key contributors to the A1’s top-speed capability

• Low drag coefficient: 0.31
• Front-mounted turbo engine with direct injection
• Light kerb weight: 1,090 kg
• Optimised gearing in the 5-speed manual transmission

The A1’s gearing ensures the engine sits near its 5,000–5,500 rpm power peak when approaching maximum velocity.

Acceleration & Real-World Speed Behaviour

The 1.0-litre TFSI delivers 95 hp and 175 Nm of torque across a wide 2,000–3,500 rpm band, giving it a flexible, confident feel on the road.

Acceleration figures

Mid-range performance is where this engine shines, thanks to its turbocharger and intercooler combination.

Engine Overview: The Heart Behind the Speed

The A1 25 TFSI uses the CHZL/DKLA 1.0-litre three-cylinder engine from the VW Group EA211 family.

Engine specifications

• Displacement: 999 cm³
• Configuration: Inline-3
• Power: 95 hp @ 5,000–5,500 rpm
• Torque: 175 Nm @ 2,000–3,500 rpm
• Fuel system: Direct injection
• Aspiration: Turbocharged with intercooler
• Compression ratio: 10.5
• Valves per cylinder: 4
• Oil capacity: 4 litres
• Cooling system: 6.2 litres

The engine’s broad torque band is crucial for maintaining strong speed progression even in higher gears.

Aerodynamics & Stability at High Speeds

With a drag coefficient of 0.31, the Audi A1 Sportback cuts cleanly through airflow. Its compact stance, well-damped suspension, and rigid MQB A0 platform ensure high-speed stability.

Stability-enhancing factors

• Long 2,563 mm wheelbase
• Independent McPherson front suspension
• Independent rear suspension with springs
• Electric power steering tuned for motorway stability
• Ventilated front discs and rear disc brakes

At speeds above 140 km/h, the car remains composed with predictably firm steering feedback.

Gearbox & Ratio Influence on Top Speed

The A1 25 TFSI comes with a 5-speed manual transmission, tuned to balance acceleration and cruising efficiency.

Why the 5-speed gearbox works

• 1st–3rd gears optimised for urban acceleration
• 4th gear provides mid-range flexibility
• 5th gear aligns perfectly with the 95-hp engine’s power curve for top speed

At approximately 118 mph, the engine reaches its peak power band, ensuring maximum sustained velocity.

Fuel Efficiency at High Speeds

The 25 TFSI is one of the most economical petrol engines in its category.

WLTP consumption

Even near 120 mph, the engine’s small displacement and efficient design help maintain relatively low consumption.

Weight, Dimensions & How They Affect Speed

The A1’s lightweight build plays a major role in its top-speed performance.

Vehicle mass & limits

• Kerb weight: 1,090 kg
• Max weight: 1,630 kg
• Max load: 540 kg
• Roof load limit: 75 kg

Dimensions

• Length: 4,029 mm
• Width: 1,740 mm (1,940 mm with mirrors)
• Height: 1,433 mm
• Wheelbase: 2,563 mm

These proportions enhance stability and aerodynamic efficiency.

Tyres, Wheels & High-Speed Traction

The standard tyre setup directly influences high-speed confidence.

• Tyre size: 185/65 R15
• Wheel size: 5.5J×15

While geared for comfort and fuel economy, these tyres remain stable at highway speeds. Upgrading to 16"–17" wheels improves grip during high-speed cornering.

Braking Performance & High-Speed Safety

The A1 25 TFSI is equipped with:

• Front ventilated discs
• Rear discs
• ABS
• Electric power steering

These systems ensure predictable stopping performance even from high speeds.

Boot Space, Practicality & Load Impact on Speed

The A1’s 335-litre boot offers generous room for its class. However, for maximum speed performance, lighter loads help the engine maintain velocity more easily.

• Fuel tank: 40 litres
• Driving range: 650–700 km in mixed conditions
