Audi A5 Sportback 2.0 TDI Ultra 2017: 70.6mpg Diesel Review

The 2017 Audi A5 Sportback 2.0 TDI Ultra stands out as a benchmark in the premium hatchback segment, blending exceptional fuel efficiency with strong performance and an upscale interior. This model delivers 70.6mpg combined economy and just 112g/km CO2 emissions, making it ideal for cost-conscious buyers who refuse to compromise on luxury or style.

Design and Exterior Appeal

Audi’s design team crafted the A5 Sportback with a sleek, aerodynamic profile that emphasizes elegance over aggression. The 2017 facelift introduced sharper lines, a bolder grille, and matrix LED headlights on higher trims, enhancing its road presence. Measuring over 4.7 meters long, it offers a low-slung stance with a sloping roofline that seamlessly integrates the extra doors without sacrificing the coupe-like silhouette.

Available in Sport or S line packages, the exterior features 18-inch alloys as standard, with options up to 20 inches. The Ultra variant prioritizes efficiency with underbody panels and low-rolling-resistance tires, yet maintains visual poise. Compared to rivals like the BMW 4 Series Gran Coupe, the A5’s styling feels more harmonious and less polarizing, appealing to a broader audience.

• Aerodynamic efficiency: Cd figure of 0.28 for optimal fuel savings.
• LED lighting: Standard daytime running lights and optional adaptive matrix beams.
• Wheel options: From 17-inch Ultra-specific alloys to 19-inch S line designs.

Powertrain and Performance Excellence

At the heart of the 2017 A5 Sportback Ultra is a 2.0-liter four-cylinder TDI diesel engine producing 187bhp and a robust 400Nm of torque from just 1,750rpm. This setup propels the car from 0-62mph in 7.9 seconds, with in-gear flexibility that shines on motorways. The low-end torque ensures effortless overtaking, rarely requiring downshifts.

Paired exclusively with a seven-speed S tronic dual-clutch automatic, gear changes are smooth and responsive, especially in Drive or Sport modes. Paddle shifters allow manual control for spirited drives, mitigating any hesitation during stop-start traffic. Top speed is electronically limited to 144mph, but real-world cruising at 70mph yields impressive economy figures.

While not as engaging as a BMW counterpart, the A5 prioritizes composure. Quattro all-wheel drive is optional, adding grip on wet roads without much economy penalty.

Interior Luxury and Practicality

Step inside, and the A5 Sportback reveals a cabin rivaling pricier Audis. High-quality materials like soft-touch plastics, leather upholstery, and aluminum trims create a premium ambiance. The driving position is near-perfect, with supportive seats offering ample adjustment, though the steering wheel height might feel slightly elevated for taller drivers.

Space for four adults is generous, with 480 liters of boot capacity expanding to 1,300 liters with seats folded. Rear legroom suits adults on long trips, and the optional storage pack adds cupholders and nets. Tech highlights include the MMI infotainment with 7-inch screen, sat-nav, and Bluetooth, upgradable to Virtual Cockpit digital gauges.

• Seating: Electrically adjustable front seats with memory on higher specs.
• Climate: Dual-zone automatic with rear vents.
• Storage: Deep door bins, central armrest cubby, and 60/40 split rear bench.

Driving Dynamics and Ride Quality

On the move, the A5 Sportback Ultra impresses with its balanced chassis. The MLB Evo platform reduces weight by 120kg over predecessors, improving agility. Suspension tuning favors comfort, absorbing bumps gracefully while limiting body roll in corners. Steering is precise, though lacking the feedback of sportier rivals.

Noise insulation is exemplary; the diesel remains hushed at cruise, with only grumbly notes under hard acceleration. Highway refinement is a highlight, where wind and tire noise are minimal. For urban use, the S tronic eases parking maneuvers, aided by rear sensors standard.

Safety and Technology Features

The 2017 A5 earned a five-star Euro NCAP rating, thanks to standard airbags, stability control, and attention assist. Options like adaptive cruise, lane keep, and 360 cameras elevate it further. The Ultra model’s efficiency aids company car drivers with low BIK tax.

Infotainment evolves with Apple CarPlay/Android Auto on later builds, plus a 10-speaker audio system. Wireless charging and ambient lighting add modern flair.

Running Costs and Ownership

With 70.6mpg and 112g/km CO2, the Ultra undercuts petrol variants significantly. Road tax is minimal, and residuals hold strong due to Audi’s reputation. Servicing intervals are 10,000 miles, with warranty up to five years via prepaid plans.

Insurance groups range 25-35, reflecting its safety credentials. Fuel costs average £0.08 per mile at 2026 prices, far below thirstier rivals.

Pros and Cons at a Glance

• Pros: Superb economy, refined engine, spacious boot, premium build.
