Driving Character: Ferrari 812 Superfast vs Porsche 911 GT3 RS
The Ferrari 812 Superfast delivers a visceral, raw experience defined by its 789hp naturally aspirated V12. The steering is exceptionally sharp, requiring precise inputs to manage the power delivery to the rear wheels, aided significantly by the rear-wheel steering system. It excels at high speeds but demands total focus as the limits of adhesion are tested. The chassis balance is classic front-engine GT, though the weight of the drivetrain is always apparent. It is a car that rewards a disciplined driver while punishing complacency, especially on damp British tarmac where the torque can easily overwhelm the traction control.
The Porsche 911 GT3 RS is essentially a road-legal race car, featuring aggressive aerodynamic aids that generate genuine downforce. The 4.0L flat-six is at its most extreme here, delivering 518hp with a razor-sharp throttle response. The chassis is incredibly stiff, tuned for maximum track precision, which makes for a highly intense driving experience on public roads. The steering feel is unparalleled, transmitting every nuance of the road surface directly to the driver’s palms. It is a machine that demands complete, unwavering commitment, rewarding the skilled pilot with performance levels that exceed almost anything else in the production world.
Head-to-head, the division is clear: the Ferrari 812 Superfast — Naturally aspirated 6.5L V12; 789hp of pure, unfiltered theatricality; the Porsche 911 GT3 RS — Aerodynamic chassis hardware; extreme downforce keeps the 4.0L flat-six pinned through high-speed turns. Characteristic of the Ferrari 812 Superfast: RWD at this power level demands skill; rear-wheel steering aids stability. For the Porsche 911 GT3 RS: Race-derived suspension tuning; rapid steering feedback ensures immediate inputs at the limit. In outright terms it is 789 hp against 518 — a 271 hp gap — and the Ferrari 812 Superfast reaches 60 mph 0.3s sooner.
Interior & Cabin: Ferrari 812 Superfast vs Porsche 911 GT3 RS
Inside the 812 Superfast, the cabin prioritises driver focus while retaining an air of grand touring luxury. The architecture features a sweeping dashboard that wraps around the occupant, with high-quality materials and bespoke trim options defining the space. The optional Daytona-style seats offer excellent lateral support for spirited driving, and the driver-centric interface places all essential controls within immediate reach. However, the sheer length of the bonnet remains a persistent factor when navigating tight spaces, necessitating careful judgement of the front extremities despite the high level of interior finish and overall build quality.
Inside, the Porsche 911 GT3 RS is stripped to the bone, with CFRP door panels and a roll cage serving as the primary design features. Carbon bucket seats are standard, locking the driver in place for high-G maneuvers. The cabin is purposefully sparse, lacking luxury padding in favour of weight-saving measures that prioritize speed. While road and wind noise are prominent at motorway speeds due to the lack of sound deadening, this is expected in a model of this focus. Everything is designed to be functional and lightweight, creating a pure, motorsport-inspired workspace that keeps the driver focused on the tarmac.
Head-to-head, the division is clear: the Ferrari 812 Superfast — Sweeping GT cabin; more space and luxury than mid-engine stablemates; the Porsche 911 GT3 RS — Driver-centric interface; digital steering wheel buttons manage advanced damper and differential settings. Characteristic of the Ferrari 812 Superfast: Optional Daytona-spec seats for serious driver engagement. For the Porsche 911 GT3 RS: Carbon bucket seats provide lateral support; stripped dashboard reduces weight and increases focus.
Daily Usability: Ferrari 812 Superfast vs Porsche 911 GT3 RS
For such a potent machine, the Ferrari 812 Superfast is surprisingly civilised as a long-distance companion. The 320-litre boot provides adequate space for luggage, making it the most practical front-engine offering in the modern Ferrari hierarchy. While it is perfectly comfortable over long motorway stints thanks to the compliant suspension settings, its width and length make urban manoeuvrability a chore. It demands constant vigilance in narrow city streets, yet it handles parking ramps and standard errands with enough grace to allow for genuine usability, provided the driver is prepared to manage its substantial dimensions.
Daily usability is deliberately limited in the Porsche 911 GT3 RS, though it remains technically legal for the road. The nose lift system is a necessity for clearing urban obstacles, preventing damage to the sophisticated front splitter. Storage is limited to the front trunk, which is adequate for track day essentials but not for large loads. Ingress and egress are physically demanding, requiring one to clear the roll cage. The suspension is too firm for comfort on broken surfaces, making long-distance commuting fatiguing. It is a specialized weapon meant for the circuit, not a daily companion for errands.
Head-to-head, the division is clear: the Ferrari 812 Superfast — 320L boot capacity; most practical front-engine Ferrari; the Porsche 911 GT3 RS — Optimised front trunk storage; 132L volume allows for light luggage despite aerodynamic focus. Characteristic of the Ferrari 812 Superfast: Dual-zone climate and Grand Tourer spec suits long-distance journeys. For the Porsche 911 GT3 RS: Short overhangs aid geometry; 105 mm ground clearance manages moderate inclines with care. that means 320 litres of boot space against 0, and everyday running costs that favour the Porsche 911 GT3 RS at the pumps.
Ownership: Ferrari 812 Superfast vs Porsche 911 GT3 RS
As one of the final front-engined, naturally aspirated V12 masterpieces, the 812 Superfast enjoys a sterling reputation among collectors. Residual values remain robust, supported by the car's status as a pinnacle of traditional Ferrari engineering. Ownership costs, however, are substantial, with specialist maintenance required to keep the complex V12 running at peak performance. While annual service costs are significant, the peace of mind offered by professional maintenance is essential for preserving the vehicle's long-term value, as enthusiasts continue to favour these unadulterated powerplants over the industry’s shift toward smaller displacement and electrification.
Owning a Porsche 911 GT3 RS is a commitment to the pinnacle of naturally aspirated performance, and it carries the costs to match. With its motorsport-derived components, maintenance is frequent and expensive, requiring specialist knowledge that the Porsche Motorsport network provides. Insurance premiums are significant given the car’s market value and performance potential. However, its scarcity and extreme engineering ensure that it remains a high-value asset, with strong residuals and a dedicated community of owners. It is a long-term investment that requires dedicated resources but pays off with an experience that few other machines can provide.
Head-to-head, the division is clear: the Ferrari 812 Superfast — Last naturally aspirated V12 front-engine Ferrari drives collector sentiment; the Porsche 911 GT3 RS — High collector value; engineering pedigree ensures that market desirability remains extremely elevated. Characteristic of the Ferrari 812 Superfast: Strong residuals; 812 variants hold value due to N/A purist appeal.
