Driving Character: Aston Martin DBS Superleggera vs Mercedes-AMG SL 63

The DBS Superleggera is defined by the sheer ferocity of its 5.2-litre twin-turbo V12, a powerplant that delivers 715hp with an unrelenting, surging intensity. Unlike its more surgical rivals, the car prioritises theatre and immense torque, relying on its rear-wheel-drive architecture to provide a raw, visceral driving experience. The chassis is tuned for stability at triple-digit speeds, though it occasionally struggles to mask its weight through tight, technical corners. It feels like a heavyweight prize fighter—monumentally powerful and capable of incredible feats, yet demanding a firm hand to keep its formidable energy under precise control at all times.

The Mercedes-AMG SL 63 transitions the lineage toward a sophisticated grand tourer profile, prioritising compliance over the surgical precision of its predecessor. The 4.0-litre twin-turbo V8 delivers a relentless surge of torque, managed by an all-wheel-drive system that ensures composure in challenging UK conditions. While the AMG Active Ride Control suspension offers remarkable poise for a heavy convertible, the steering feel remains somewhat insulated compared to pure sports cars. It excels as a high-speed cruiser rather than a track-day weapon, favouring long-distance refinement and effortless pace over the frantic, razor-sharp feedback once associated with the AMG brand.

Head-to-head, the division is clear: the Aston Martin DBS Superleggera — 5.2L twin-turbocharged V12; provides massive low-end torque for effortless high-speed progress; the Mercedes-AMG SL 63 — SL 63 AWD with active rear steering; more dynamic than SL predecessors. Characteristic of the Aston Martin DBS Superleggera: Rear-wheel drive dynamics; chassis maintains composure despite immense engine output. For the Mercedes-AMG SL 63: 577hp V8 with characteristic AMG torque delivery across the rev range. In outright terms it is 715 hp against 577 — a 138 hp gap — and the Aston Martin DBS Superleggera reaches 60 mph 0.2s sooner.

Interior & Cabin: Aston Martin DBS Superleggera vs Mercedes-AMG SL 63

Inside, the cabin is an exercise in excess and traditional elegance, heavily draped in high-quality leather and aluminium accents. The layout follows a classic grand touring aesthetic, prioritising comfort over the minimalist tech focus seen in the latest generation of supercars. While the materials are undeniably opulent, the infotainment system feels dated, reflecting the development cycle of its era. The seating position is low and supportive, perfectly suited for long-distance cruising, even if the user interface occasionally requires more effort than the streamlined systems found in current, competition-focused rivals within the same price bracket.

Inside, the SL 63 feels thoroughly modern, dominated by a portrait-oriented MUX interface that dictates the cabin aesthetic. The digital cockpit is crisp, though the heavy reliance on touch-sensitive surfaces can feel counterintuitive when pressing on. Material quality is excellent, with high-grade leathers and metals, yet the ergonomics are compromised by the vestigial rear seats, which serve more as shelf space than viable seating. It lacks the intimate, driver-focused cocoon of the previous AMG GT, opting instead for a broad, open-air cockpit design that prioritises perceived luxury and connectivity over raw, tactile immersion.

Head-to-head, the division is clear: the Aston Martin DBS Superleggera — Luxury-focused cabin; premium leather materials deliver a refined grand touring environment; the Mercedes-AMG SL 63 — Soft-top roadster with genuine 2+2 rear seats returned to SL range. Characteristic of the Aston Martin DBS Superleggera: Driver-focused layout; integrates modern technology with traditional artisan interior finishes. For the Mercedes-AMG SL 63: MBUX Hyperscreen available; most technology-forward SL interior ever.

Daily Usability: Aston Martin DBS Superleggera vs Mercedes-AMG SL 63

For all its performance, the DBS Superleggera remains a usable grand tourer, provided one understands the limitations of its 244-litre boot. Ingress and egress are straightforward for a car of this profile, and the ride, while firm, is well-damped for motorway work, making it an excellent candidate for long-haul journeys. Urban environments present the greatest challenge; its width and aggressive stance can make tight parking situations stressful. It is an assertive presence on the road, offering a level of comfort that suits high-speed cruising perfectly, provided one keeps the long, muscular bonnet clear of low-speed obstacles.

Daily utility is remarkably improved, largely due to the transition to a fully variable fabric roof that saves significant boot space and lowers the centre of gravity. The 213-litre capacity remains tight, though it accommodates soft luggage better than the old hard-top systems. Parking remains a chore; the wide, low-slung bodywork requires cautious navigation through tight urban gaps, and the extensive bonnet length demands foresight. Nevertheless, the sophisticated suspension tuning allows it to soak up poorly maintained road surfaces with grace, making it a viable, albeit thirsty, companion for regular motorway commutes and long-distance touring.

Head-to-head, the division is clear: the Aston Martin DBS Superleggera — 244L boot capacity; accommodates enough luggage for extended grand touring trips; the Mercedes-AMG SL 63 — Roof mechanism reliable and rapid; usable as open-top grand tourer. Characteristic of the Aston Martin DBS Superleggera: 120mm ground clearance; sufficient for standard speed bumps and driveway transitions. For the Mercedes-AMG SL 63: AWD enables year-round use in all climates; better versatility than predecessors. that means 270 litres of boot space against 213, and everyday running costs that favour the Mercedes-AMG SL 63 at the pumps.

Ownership: Aston Martin DBS Superleggera vs Mercedes-AMG SL 63

Running a V12-powered DBS Superleggera requires commitment, as the high-output engine and premium components result in significant annual maintenance costs. The model benefits from a well-established dealer network, but owners should be prepared for the realities of high-performance parts and servicing. As an out-of-production model, it has reached a point of relative stability in the second-hand market, though it is not a car that will ever be considered inexpensive to keep. It remains a coveted choice for enthusiasts seeking the definitive V12 Aston Martin experience before the forced transition to smaller displacement, forced-induction powertrains.

Ownership is bolstered by the vast, well-integrated Mercedes-Benz dealer network, which provides consistent support for the complex AMG powertrain. Maintenance costs are steep, with annual services reflecting the performance-oriented nature of the twin-turbo V8, and the intricate soft-top mechanism introduces a long-term servicing variable that owners must anticipate. While depreciation is generally mitigated by the enduring prestige of the SL moniker, the market is competitive. Reliability is generally predictable, provided the rigid servicing intervals are respected, ensuring the complex electronics and drivetrain remain within optimal operating parameters throughout the ownership period.

Head-to-head, the division is clear: the Aston Martin DBS Superleggera — Extensive brand dealer support; provides consistent maintenance for performance-oriented owners; the Mercedes-AMG SL 63 — Mercedes SL has decades of reliability history; latest generation expected to continue. Characteristic of the Aston Martin DBS Superleggera: High prestige; luxury brand status ensures stable demand in the enthusiast market. For the Mercedes-AMG SL 63: Broad dealer network and long-running support programmes. On the wallet the two diverge at £175,000 versus £165,000 — a £10,000 difference, with annual maintenance of £4,200 against £1,500.
