Audi A5 Ultra 2025: Up To 67.3 MPG Efficient Sportback

The Audi A5 Ultra redefines what a luxury coupe can achieve by prioritizing fuel efficiency without sacrificing the brand’s signature refinement and style. This model targets drivers who demand premium comfort on long journeys while keeping running costs low. With its sleek lines and advanced diesel powertrain, it delivers impressive economy figures alongside a composed ride, making it a smart choice for both personal and company car users.

Design and Exterior Appeal

Audi’s design language shines in the A5 Ultra, featuring a low-slung coupe profile that turns heads with its aggressive front grille, sharp LED headlights, and flowing roofline. The ‘Ultra’ designation highlights its eco-focused tuning, but the aesthetics remain sporty and upscale. Available in Sportback variants, it offers a liftback for added practicality, distinguishing it from traditional two-door coupes.

Wheel options range from 17-inch alloys on base models to larger 19-inch rims on higher trims, enhancing its road presence. Aerodynamic tweaks, like active grille shutters, contribute to its efficiency without compromising visual drama. Paint choices include metallic finishes that accentuate its curves, ensuring it fits seamlessly into Audi’s premium lineup.

Powertrain and Performance

At the heart of the A5 Ultra is a 2.0-liter TDI diesel engine producing around 190 PS (177 hp) and a robust 400 Nm of torque. Paired with a seven-speed S tronic dual-clutch transmission and Quattro all-wheel drive in select markets, it accelerates from 0-62 mph in approximately 7.9 seconds, with a top speed nearing 146 mph.

Real-world performance emphasizes smooth cruising over outright thrills. The engine pulls strongly from low revs, ideal for overtaking on highways. While not as visceral as the S5 or RS5, it offers composed handling with precise steering, though some critics note it lacks the sharpness of rivals like the BMW 3 Series.

This table compares key specs, showing the A5 Ultra’s torque advantage for effortless acceleration.

Fuel Economy and Efficiency

The standout feature is its exceptional fuel efficiency. Official NEDC figures claim up to 67.3 mpg combined, with real-world tests averaging 53.7 mpg overall—57.6 mpg on motorways and 47.8 mpg in urban settings. CO2 emissions sit at 109-112 g/km, placing it in low company car tax bands (16-24% BiK).

• Motorway prowess: Ideal for high-mileage commuters, often exceeding 50 mpg.
• Urban flexibility: Maintains respectable economy despite diesel’s strengths on open roads.
• Eco credentials: Ultra badging signals optimized aerodynamics and engine mapping for minimal emissions.

Compared to petrol variants like the 2025 A5’s 2.0 TFSI (26/36 mpg EPA), the diesel Ultra excels in efficiency, though newer models incorporate mild-hybrid tech for further gains.

Interior Quality and Comfort

Step inside, and the A5 Ultra envelops you in Audi’s renowned build quality. Soft-touch materials, intuitive controls, and optional leather upholstery create a luxurious ambiance. The cabin feels sophisticated, with high-quality plastics and haptic feedback on buttons that rivals pricier models.

Front seats are supportive with ample adjustment, including lumbar support on higher trims. Rear space in the Sportback is generous for adults, aided by a panoramic sunroof option that enhances airiness. The dual-screen infotainment—MMI system with navigation—dominates the dash, though some find it screen-heavy.

• Tech highlights: Standard Apple CarPlay, Android Auto, and digital gauges.
• Comfort features: Adaptive cruise control, lane assist in assistance packs.
• Cargo versatility: Up to 23 cubic feet with seats up in Sportback, outpacing sedan rivals.

Driving Dynamics and Ride

On the road, the A5 Ultra prioritizes refinement over sportiness. Its suspension absorbs bumps effortlessly, shrugging off potholes and speed humps with minimal intrusion. Quattro grip ensures stability in wet conditions, while the ride remains forgiving yet controlled.

Steering is accurate but lacks feel, making it less engaging than a BMW counterpart. It’s an excellent motorway cruiser, hushed at speed with low wind noise. For twisty roads, it handles predictably but won’t excite keen drivers.

Practicality and Versatility

Despite its coupe styling, the Sportback variant boosts usability with a wide hatch and 23 cu ft cargo space—far more than the BMW 3 Series trunk. Folding seats expand this further, accommodating bikes or luggage easily. It’s a practical choice for families or business users needing load-lugging capability.

Company car appeal is strong due to low BiK rates and high residuals. Base pricing starts around £30,000, with loaded models nearing £37,000 including nav and safety packs.

Safety and Technology Features

Audi equips the A5 Ultra with comprehensive safety tech. Standard kits include autonomous emergency braking, lane-keeping, and traffic sign recognition. Optional adaptive cruise and parking aids elevate it further. Euro NCAP ratings for similar A5 models are five stars, underscoring its safety.

Infotainment evolves with touchscreens handling climate, nav, and media. Voice control and wireless charging add convenience, though the all-digital interface demands adaptation.

Ownership Costs and Reliability

Running costs are a highlight: low fuel and tax bills offset premium servicing. Warranty is three years/60,000 miles, with strong residuals aiding leasing. Reliability matches Audi standards, though diesel maintenance requires attention to DPF filters.

Pros and Cons

• Pros: Outstanding economy, premium interior, practical Sportback, refined ride.
• Cons: Steering lacks feedback, screen-heavy dash, not dynamically thrilling.

Who Should Buy the Audi A5 Ultra?

Ideal for motorway warriors, company car drivers, or anyone valuing efficiency in a luxury wrapper. Skip if you crave raw excitement—opt for S5 instead.
