The Audi S4 Avant stands out as a versatile estate that combines high-speed capability with everyday practicality. Powered by a robust 3.0-liter V6 diesel engine producing around 347 horsepower, it accelerates from 0-62 mph in just 4.9 seconds while offering impressive fuel efficiency for its class. This model appeals to drivers seeking excitement without sacrificing space or refinement.
Powertrain and Acceleration Excellence
At the heart of the S4 Avant lies a sophisticated 3.0-liter V6 turbodiesel engine, delivering 347 hp and substantial torque from as low as 1,370 rpm up to 4,500 rpm. Paired with an eight-speed automatic transmission and Audi’s renowned quattro all-wheel-drive system, it ensures seamless power delivery across all conditions. The 48-volt mild-hybrid technology enhances throttle response, making it feel more eager than typical diesels, despite a characteristic engine note.
Performance figures confirm its prowess: 0-62 mph in 4.9 seconds for the estate, slightly behind the saloon’s 4.7 seconds due to added weight, yet still blisteringly quick. Top speed is electronically limited to 155 mph. Real-world tests show it maintains composure on motorways and twisty roads alike.
Handling and Driving Dynamics
The S4 Avant’s chassis benefits from a lighter, stiffer setup with reconfigured quattro system, providing immense grip through corners thanks to wide tires and four-wheel drive. Steering is direct and weighted appropriately, addressing past criticisms of vagueness in Audi models. It feels planted and agile, threading through B-roads effortlessly without feeling oversized.
However, the firm suspension prioritizes handling over plushness. On UK roads, it can feel fidgety over bumps and potholes, even in comfort mode, though it smooths out at higher speeds. This trade-off suits enthusiasts who value dynamic poise over absolute ride comfort.
| Aspect | Strengths | Weaknesses |
|---|---|---|
| Grip & Stability | Quattro AWD, wide tires | Suspension firmness |
| Steering | Direct, responsive | Not the most communicative |
| Ride Quality | Composed at speed | Bumpy at low speeds |
Interior Comfort and Quality
Audi’s cabin craftsmanship shines in the S4 Avant, featuring premium materials like diamond-stitched leather, Alcantara, and tasteful brightwork. Front sports seats offer excellent support, adjustability, and even massage functions in some trims, ideal for long journeys. The driving position is spot-on, with the Virtual Cockpit digital gauge cluster providing customizable displays, including detailed navigation.
Rear space is generous, accommodating six-foot passengers comfortably behind similarly tall drivers, with ample headroom. The design blends style and function seamlessly. Standard kit includes a 10.1-inch touchscreen for sat-nav and infotainment, though the shift to full touchscreen controls divides opinions.
Practicality and Load Space
As an Avant estate, practicality is a highlight. The boot offers over 495 liters with seats up (expandable to 1,495 liters folded), surpassing many rivals and belaying its 420-liter claim in some specs due to clever packaging. Roof bars enable extra cargo for family trips, and the low load lip eases heavy lifting.
- Spacious rear seats for adults or child seats
- Versatile boot with 40/20/40 split-folding
- Ideal for weekend getaways or daily family duties
- Quattro aids in adverse weather without SUV bulk
Owners praise its long-distance comfort, averaging 33-42 mpg on mixed drives, with a real-world range around 400 miles.
Fuel Economy and Efficiency
Official WLTP figures quote 39.8 mpg combined with 166 g/km CO2, achievable gently on motorways (40-42 mpg), dropping to 35 mpg in spirited use. The diesel’s broad torque band and efficient eight-speed gearbox contribute to strong economy for a performance wagon.
Technology and Safety Features
Loaded with tech, the S4 includes adaptive cruise control, lane-keeping assist, and a premium sound system in higher packs. The MMI system supports Android Auto and Apple CarPlay wirelessly. Safety ratings are strong, bolstered by quattro traction.
Ownership Costs and Reliability
Pricing starts around £49,400, with well-specced models under £53,000 including panoramic roof and comfort packs. Running costs benefit from diesel efficiency and 3-year warranty. Real-world ownership reports highlight comfort on long trips and winter capability, though frequent fills are noted versus larger tanks.
Pros and Cons Overview
- Pros: Explosive acceleration, superior grip, premium interior, vast practicality, solid efficiency
- Cons: Firm ride on poor roads, diesel noise, touchscreen-heavy controls
