Driving Character: Mercedes-AMG SL 63 vs McLaren 570S
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.
The McLaren 570S stands as the quintessential entry-level supercar, utilising a lightweight carbon fibre monocoque that provides unmatched structural rigidity. Its 3.8L twin-turbo V8 delivers 562 hp, propelling the car to 60 mph in a mere 3.1 seconds. The hydraulic-assisted steering is widely regarded as the benchmark for the segment, offering granular detail that feels missing in its competitors. While the engine displays noticeable turbo lag at lower rpm, the chassis balance is sublime, providing a sense of fluidity and poise that invites the driver to push harder through every apex with complete confidence.
Head-to-head, the division is clear: the McLaren 570S takes our 0-100 driving character grading, 78 against 90. Characteristic of the Mercedes-AMG SL 63: Composed, quattro-like AWD grip with genuine open-top GT character. For the McLaren 570S: Sharp, communicative entry-level McLaren with genuine supercar dynamics. In outright terms it is 577 hp against 562 — a 15 hp gap — and the McLaren 570S reaches 60 mph 0.4s sooner.
Interior & Cabin: Mercedes-AMG SL 63 vs McLaren 570S
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.
The cabin focuses on a minimalist, driver-centric design that eschews excessive ornamentation in favour of functional elegance. High-grade leather and Alcantara dress the interior, creating a cabin that feels both sophisticated and purposeful. The vertical infotainment screen is undeniably dated compared to modern rivals and can be unresponsive, which remains the system's primary weakness. Visibility is genuinely impressive, thanks to the thin A-pillars and the unique dihedral door design, which not only eases ingress but also makes the car feel like a significant event every time the driver settles into the cockpit.
Head-to-head, the division is clear: the Mercedes-AMG SL 63 takes our 0-100 interior & cabin grading, 85 against 70. Characteristic of the Mercedes-AMG SL 63: Luxurious, modern cabin with excellent build quality. For the McLaren 570S: Driver-focused cockpit, decent usability for a McLaren.
Daily Usability: Mercedes-AMG SL 63 vs McLaren 570S
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.
For a mid-engined supercar, the 570S is remarkably accommodating in day-to-day scenarios. The suspension setup is soft enough to handle urban speed bumps and undulating B-roads without breaking the driver’s spine, cementing its status as the most road-biased model in the McLaren stable. With a usable 150-litre rear boot and an additional front storage area, it manages supermarket runs and light luggage far better than its rivals. However, the low ride height makes parking kerbs a genuine hazard, necessitating the optional nose lift system to protect the front splitter from unnecessary and expensive damage.
Head-to-head, the division is clear: the Mercedes-AMG SL 63 takes our 0-100 daily usability grading, 68 against 55. Characteristic of the Mercedes-AMG SL 63: Comfortable, capable long-distance convertible for daily use. For the McLaren 570S: Usable as an occasional daily supercar. that means 213 litres of boot space against 150, plus a usable front boot in the McLaren 570S.
Ownership: Mercedes-AMG SL 63 vs McLaren 570S
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.
As the gateway to the McLaren family, the 570S represents a balanced proposition for the aspiring supercar owner. Residuals have remained robust across the Sports Series, helped by a reputation for being the most usable model in the range. Maintenance is a significant consideration, with annual servicing costing around £2,800, and owners must be prepared for the specific costs associated with DCT transmission care. The McLaren network is comprehensive and highly professional, ensuring that support is readily available, though the high performance of the twin-turbo V8 means regular, proactive inspection is non-negotiable for long-term health.
Head-to-head, the division is clear: the Mercedes-AMG SL 63 takes our 0-100 ownership grading, 68 against 68. Characteristic of the Mercedes-AMG SL 63: Backed by Mercedes-AMG's established reliability record. For the McLaren 570S: Now a discontinued entry point into McLaren ownership. On the wallet the two diverge at £165,000 versus £95,000 — a £70,000 difference, with annual maintenance of £1,500 against £2,800.
