Driving Character: Ferrari 12Cilindri vs Mercedes-Benz SLR McLaren
The 12Cilindri defines a new peak for front-mounted V12 performance, combining an 830hp naturally aspirated powerplant with a remarkably agile rear-wheel-drive chassis. The four-wheel steering system effectively masks the long wheelbase, granting this grand tourer a nimbleness that defies its size. While the 6.5L engine demands high-rev engagement for maximum effect, the chassis balance remains composed even when pushing near the limits of adhesion. It represents a sophisticated evolution of the 812 lineage, ensuring that the raw, mechanical intensity of the V12 remains the primary focus of the driving experience.
The Mercedes-Benz SLR McLaren is a brutal manifestation of early 2000s super-GT excess, defined by a hand-built 5.4-litre supercharged V8 that delivers 617hp with unrelenting force. Its long-bonnet, front-mid engine layout dictates a heavy, rear-biased handling balance, accompanied by the visceral, side-exit exhaust note. While capable of prodigious speeds, it does not possess the agility of modern mid-engined peers. The steering is direct but weighty, and the overall driving experience is characterised by theatrical, high-speed stability rather than delicate cornering precision, requiring a firm hand to manage the immense torque and significant kerb weight.
Head-to-head, the division is clear: the Ferrari 12Cilindri takes our 0-100 driving character grading, 92 against 78. Characteristic of the Ferrari 12Cilindri: Naturally-aspirated V12 drama in a more refined, usable GT package. For the Mercedes-Benz SLR McLaren: Dramatic, supercharged V8 GT with genuine McLaren engineering input. In outright terms it is 830 hp against 617 — a 213 hp gap — and the Ferrari 12Cilindri reaches 60 mph 0.9s sooner.
Interior & Cabin: Ferrari 12Cilindri vs Mercedes-Benz SLR McLaren
Inside, the dual-cockpit dashboard draws clear inspiration from the 365 GTB/4, blending classic design motifs with a modern digital architecture. The interior feel is focused squarely on driver immersion, with the digital instrument cluster and infotainment system seamlessly integrated into the minimalist aesthetic. Materials are finished to an exceptional standard, reflecting the car's grand touring intent. While the cabin is clearly a masterclass in modern Ferrari ergonomics, the rear seats remain purely vestigial, serving as additional storage rather than a functional space for passengers.
The interior represents a peculiar blend of McLaren-derived carbon fibre construction and Mercedes-Benz switchgear, resulting in a cabin that feels both bespoke and familiar. The butterfly doors provide an unparalleled sense of arrival, though the low-slung, cramped cabin makes ingress a deliberate process. Once inside, the driver is met with premium MB-Tex and structural carbon, though the infotainment and navigation systems are clearly relics of their era. Despite this, the hand-finished quality remains high, offering a uniquely dramatic environment that prioritises sensory impact over the ergonomic cleanliness expected in contemporary performance vehicles.
Head-to-head, the division is clear: the Ferrari 12Cilindri takes our 0-100 interior & cabin grading, 85 against 75. Characteristic of the Ferrari 12Cilindri: Straightforward, user-friendly cabin with genuine usability. For the Mercedes-Benz SLR McLaren: Luxurious, distinctive cabin with genuine period-correct drama.
Daily Usability: Ferrari 12Cilindri vs Mercedes-Benz SLR McLaren
Despite its performance pedigree, the 12Cilindri offers a practical, if physically imposing, approach to daily grand touring. The 270L boot provides genuine capacity for luggage, making it a viable companion for extended journeys. In urban environments, the four-wheel steering is indispensable, allowing the driver to navigate tight streets with a precision that belies the car's significant length and width. However, the long bonnet and expansive bodywork require a cautious approach in city centres and parking facilities, where the car’s sheer footprint can make tight manoeuvres feel somewhat daunting.
Daily utility is surprisingly coherent for a vehicle of this performance class, thanks to the front-mid engine configuration that allows for a functional 272-litre boot. It functions comfortably as a grand tourer, with an engine delivery that is better suited to long-distance speed than dense urban environments. The significant length and wide stance, however, render it problematic in tight parking conditions. Furthermore, the heat generated by the side-exit exhausts near the doors requires awareness during ingress and egress, a small inconvenience given the car's primary focus on highway dominance and long-legged cruising capability.
Head-to-head, the division is clear: the Ferrari 12Cilindri takes our 0-100 daily usability grading, 75 against 50. Characteristic of the Ferrari 12Cilindri: Genuinely usable as a continent-crossing daily GT. For the Mercedes-Benz SLR McLaren: Usable GT for longer journeys, if firmly sprung. that means 270 litres of boot space against 272, and everyday running costs that favour the Ferrari 12Cilindri at the pumps.
Ownership: Ferrari 12Cilindri vs Mercedes-Benz SLR McLaren
Ownership of the 12Cilindri is defined by its status as a bastion of the naturally aspirated V12 in an increasingly electrified automotive landscape. The standard 7-year warranty and maintenance programme provide a high level of security for what is fundamentally a complex, high-performance machine. While fuel consumption remains notably high and insurance costs will inevitably reflect the vehicle's extreme performance potential and price point, the long-term collector appeal of such a pure-engine model remains incredibly strong, ensuring robust residual values for those who manage the ongoing running costs.
Owning a Mercedes-Benz SLR McLaren is a commitment to maintaining an iconic, low-volume collaboration. With values now firmly in the appreciation phase, finding specialists who can source bespoke components is essential. Both Mercedes and McLaren offer support programmes, but servicing costs are astronomical, reflecting the specialised labour required for the supercharged V8 and intricate aero-components. While the rarity of the model ensures significant appeal to collectors, the maintenance overheads are not for the faint-hearted, making it an investment-grade machine that demands a dedicated, well-funded approach to long-term stewardship.
Head-to-head, the division is clear: the Ferrari 12Cilindri takes our 0-100 ownership grading, 68 against 60. Characteristic of the Ferrari 12Cilindri: One of the last naturally-aspirated V12 Ferraris, strong collector interest. For the Mercedes-Benz SLR McLaren: Now a sought-after modern classic collaboration between Mercedes and McLaren. On the wallet the two diverge at £395,000 versus £350,000 — a £45,000 difference, with annual maintenance of £0 against £5,000, and warranty cover of 7yr / unlimited mi versus 2yr / unlimited mi.
