Driving Character: Porsche 718 Cayman GT4 RS vs Ferrari 296 GTB
The Porsche 718 Cayman GT4 RS represents the apex of the 718 platform, transplanting a 493hp naturally aspirated flat-six from the GT3 into a mid-engine chassis. The result is a machine with staggering agility and a turn-in response that makes even the standard GT4 feel soft. The chassis balance is dominated by rear-end grip and sharp, responsive steering that provides constant feedback. It is an extreme instrument, demanding a high level of expertise to truly extract its full potential. The power delivery is frenetic, culminating in a high-revving wail that defines the car's racing-inspired character.
The Ferrari 296 GTB redefines mid-engine dynamics by integrating a hybrid system that provides instantaneous torque fill, effectively eliminating turbo lag. The chassis feels remarkably nimble, with the weight added by the battery and electric motor expertly masked by sophisticated suspension tuning. Steering is razor-sharp and communicative, allowing the driver to place the car with immense confidence. While the transition between electric power and the combustion engine is generally seamless, spirited driving reveals a character that demands a precise hand on the throttle to manage the immediate surge of combined hybrid torque.
Head-to-head, the division is clear: the Porsche 718 Cayman GT4 RS takes our 0-100 driving character grading, 96 against 93. Characteristic of the Porsche 718 Cayman GT4 RS: GT3-derived engine in the lightest, most track-focused Cayman ever. For the Ferrari 296 GTB: Sublime hybrid V6 chassis balance, widely rated among the best-handling Ferraris. In outright terms it is 493 hp against 819 — a 326 hp gap — and the Ferrari 296 GTB reaches 60 mph 0.5s sooner.
Interior & Cabin: Porsche 718 Cayman GT4 RS vs Ferrari 296 GTB
The interior is a study in weight reduction, featuring CFRP door panels, lightweight door pulls, and carbon bucket seats that lock the driver in place. The presence of the standard roll bar behind the seats signals its intent, creating a sparse, motorsport-focused atmosphere. Sound deadening is intentionally minimal, allowing the mechanical symphony—and the roar of the intake located just behind the driver's head—to flood the cabin. It is not designed for luxury or comfort, but rather as an extension of the driving experience, prioritising tactical feedback and material efficiency above all else.
The cabin prioritises driver focus through a high-tech, cockpit-style layout. High-quality carbon fibre and premium leather define the interior, creating an environment that feels both sophisticated and purposeful. The reliance on digital controls and haptic surfaces represents a significant departure from traditional analogue switchgear, which, while offering a modern and clean aesthetic, may feel less tactile for enthusiasts accustomed to physical buttons. Visibility is typical of a mid-engine exotic, with the digital instrument cluster providing all necessary telemetry without overwhelming the driver, successfully balancing technological advancement with essential driver-focused ergonomics.
Head-to-head, the division is clear: the Ferrari 296 GTB takes our 0-100 interior & cabin grading, 50 against 78. Characteristic of the Porsche 718 Cayman GT4 RS: Stripped-back, motorsport-focused cockpit. For the Ferrari 296 GTB: Driver-focused cabin, though haptic controls polarise reviewers.
Daily Usability: Porsche 718 Cayman GT4 RS vs Ferrari 296 GTB
Daily utility is significantly compromised by the track-oriented nature of the GT4 RS. The suspension is exceptionally firm, making it punishing on all but the smoothest road surfaces, and the lack of sound insulation makes it unsuitable for long, tedious commutes. Despite this, the front and rear trunks remain available for storage, and the inclusion of a front-axle lift system helps navigate urban obstacles. While it is technically possible to drive to the track, the RS experience is best reserved for spirited road use or dedicated circuit days rather than routine errands.
For a mid-engine supercar, the 296 GTB is surprisingly well-adapted to urban living, thanks in large part to its EV-only mode. Being able to creep silently through residential areas provides a level of refinement rarely found in this segment. The compact dimensions make it relatively easy to place on narrower roads, though the car’s very low ground clearance demands constant vigilance against steep driveways and deep kerbs. While rear visibility is admittedly restricted, the car handles the realities of city traffic with far more grace than its V8-powered predecessors.
Head-to-head, the division is clear: the Ferrari 296 GTB takes our 0-100 daily usability grading, 35 against 68. Characteristic of the Porsche 718 Cayman GT4 RS: Usable but clearly built for track days over commuting. For the Ferrari 296 GTB: More usable daily than a 12Cilindri, with some EV-only running. that means 125 litres of boot space against 105, and everyday running costs that favour the Ferrari 296 GTB at the pumps.
Ownership: Porsche 718 Cayman GT4 RS vs Ferrari 296 GTB
Owning a 718 Cayman GT4 RS is a high-stakes proposition, with high purchase prices and significant service costs reflecting its status as a low-volume, specialised performance vehicle. Values have appreciated rapidly, as the model occupies a unique space in the modern Porsche lineup. Owners benefit from the comprehensive Porsche Motorsport support network, which is essential for managing RS-specific components that are more expensive and harder to source than standard parts. It is a collector's dream, provided the owner acknowledges the substantial overheads and the demanding nature of maintaining a high-performance track machine.
Ferrari’s support network ensures that owning a 296 GTB remains a premium, discreet experience. The 7-year warranty and inclusive service plan are critical components that bolster confidence in a powertrain that incorporates significant hybrid complexity. While long-term durability regarding the electrical system remains less battle-tested than that of traditional internal combustion models, the brand's commitment to the longevity of the platform provides peace of mind. Running costs are competitive for the supercar class, and the high-tech appeal ensures it remains a desirable prospect on the secondary market.
