The short wheelbase allows for an aggressive, pointy turn-in that invites the driver to play with the car’s balance through mid-corner. While the steering is naturally heavy, it offers sufficient clarity to manage the rear-driven power delivery with confidence. It excels in delivering a raw, engaging experience that feels more mechanical and connected than its larger, heavier siblings, making it an ideal choice for the dedicated enthusiast.
The Porsche 718 Cayman GT4 is the definition of chassis purity, pairing a naturally aspirated 4.0-litre flat-six with a mid-engine layout that offers near-perfect neutrality. The 414hp delivery is linear and predictable, allowing for precise throttle modulation through technical sections of track. The manual gearbox is a highlight, featuring short, mechanical throws that engage the driver completely. While it lacks the raw top-end speed of 911-based variants, the balanced chassis and communicative steering allow it to carry immense cornering speed, making it an exceptionally rewarding tool for those who value driver input over outright power figures.
Head-to-head, the division is clear: the BMW M2 — Lightest current M car; driver-focused 453hp pure-sport driving experience; the Porsche 718 Cayman GT4 — 4.0L naturally aspirated flat-six; mid-engine architecture provides exceptional balance during corner entry.
