Driving Character: Audi RS7 vs Mercedes-AMG GT
The RS7 occupies a unique space, marrying the brutal acceleration of a 4.0L twin-turbo V8 with the visual drama of a low-slung, sweeping Sportback. With 591 hp and the advanced Quattro system, it delivers devastating straight-line performance that feels relentless and almost telepathic. All-wheel steering is standard, giving this imposing car an agility that defies its substantial weight in the corners. It is a machine designed for covering vast distances at high speed with effortless ease, providing a level of poise that turns even the most demanding road into a manageable ribbon of asphalt.
The Mercedes-AMG GT demonstrates the prowess of a front-mid engine layout, prioritising balance and direct feedback for the enthusiast driver. With 577hp directed to the rear wheels via a mechanical limited-slip differential, the car offers a visceral, involving experience. Steering is sharp and communicative, allowing for precise placement in corner apexes, though the rear-wheel-drive platform demands respect in damp conditions. Acceleration is blistering, with a 3.1-second 0-60mph sprint. While less forgiving than its AWD competitors, the AMG GT rewards committed driving with a dynamic repertoire that remains a benchmark for pure driver engagement within the contemporary supercar class.

Interior & Cabin: Audi RS7 vs Mercedes-AMG GT
The interior is a high-luxury environment, mirroring the technical sophistication of the RS6 but packaged within a more dramatic, coupe-like frame. The Virtual Cockpit Plus provides clear, customisable readouts, while the cabin's materials—ranging from carbon fibre to Valcona leather—exude a premium, tactile quality. Because of the raked roofline, the rear cabin feels more intimate than in the Avant version, sacrificing headroom for a more sporting aesthetic. It is undeniably a driver’s cabin, where every control feels weighted, precise, and purposefully placed to enhance the feeling of being in something truly exclusive.
Inside, the AMG GT presents a cockpit-like environment dominated by a high transmission tunnel and a wide, driver-centric dashboard. The interior materials are of a high standard, showcasing bespoke AMG instruments and Alcantara detailing. Space is deliberately intimate, reflecting the car’s focused nature rather than grand touring comfort. Visibility is somewhat compromised by the low-slung roofline and thick pillars, yet the driving position is perfectly aligned with the pedals and steering wheel. It is an environment designed to insulate the driver from distractions, keeping the focus squarely on the task of piloting a high-performance machine through demanding roads.
Head-to-head, the division is clear: the Audi RS7 takes our 0-100 interior & cabin grading, 88 against 84. Characteristic of the Audi RS7: Spacious, premium cabin with excellent tech and comfort. For the Mercedes-AMG GT: Genuinely usable 2+2 cabin with strong build quality.
Daily Usability: Audi RS7 vs Mercedes-AMG GT
While the RS7 is undoubtedly a performance vehicle, its Sportback design offers a practical twist. The 535L boot is more than sufficient for typical weekend trips, and the lift-back opening makes loading gear straightforward. Urban use requires awareness; its significant width and low stance mean care is needed in narrow parking structures, though the array of sensors and cameras makes it doable. In Comfort mode, the air suspension does a commendable job of masking road surface harshness, ensuring that urban traffic or motorway cruising is conducted with a sense of refined, whisper-quiet calm.
Usability in the AMG GT is naturally restricted by its performance-oriented design. The front trunk provides a 260-litre storage area, adequate for light travel but far from comprehensive for extended road trips. The suspension is remarkably firm even in Comfort mode, which can result in an unsettled ride on poor surfaces or urban speed bumps. Ingress and egress require a degree of physical dexterity, given the low ride height and sculpted seats. While the car can manage city errands, its primary habitat remains the open road where its performance credentials can be exercised without the constraints of suburban infrastructure.
Head-to-head, the division is clear: the Audi RS7 takes our 0-100 daily usability grading, 82 against 72. Characteristic of the Audi RS7: A genuine luxury daily driver with supercar-embarrassing pace. For the Mercedes-AMG GT: More practical than the previous 2-seat GT thanks to rear seats. that means 535 litres of boot space against 350, and everyday running costs that favour the Audi RS7 at the pumps.
Ownership: Audi RS7 vs Mercedes-AMG GT
As a flagship performance model, the RS7 commands a premium in terms of running costs. Fuel consumption is consistent with a high-output V8, and the long-term maintenance requires a dedicated budget for tyres, brakes, and scheduled service checks. Audi’s dealer network ensures that this level of care is easily accessible, and the car's desirable styling keeps residual values firm amongst performance-oriented buyers. It is a car that demands a commitment to its upkeep, but in exchange, it offers an ownership experience defined by style, speed, and the confidence that comes with a top-tier automotive engineering product.
Owning an AMG GT is an investment in the traditional, high-performance V8 heritage of the brand. Residual values remain strong, bolstered by consistent demand from enthusiasts who prize the V8 character. Servicing is handled through the robust Mercedes dealer network, ensuring that specialists are always within reach, though owners must prepare for high costs associated with performance-grade brakes and tyres. Annual maintenance of £1,600 is standard for the class. Insurance costs reflect the car’s high performance and the complexity of its mechanical components, yet the model remains a prized inclusion in the garages of those who value pure engagement.
Head-to-head, the division is clear: the Audi RS7 takes our 0-100 ownership grading, 75 against 68. Characteristic of the Audi RS7: Strong owner-reported reliability (4.7/5 per KBB after 50k miles). For the Mercedes-AMG GT: Backed by Mercedes-AMG's established V8 reliability record. On the wallet the two diverge at £105,000 versus £155,000 — a £50,000 difference, with annual maintenance of £1,200 against £1,600.
