991 GT3 3.8L (475Bhp)

The sportiest 911 made its world premiere at the Geneva International Motor Show: the new Porsche 911 GT3. In the 50th anniversary year of the 911, Porsche introduced a new chapter in race track performance sports cars. The 991.1 GT3 sparked controversy by replacing the renowned Metzger engine with a all-new 3.8ltr flat-six, switching from hydraulic to electric power steering, and offering only a seven-speed double-clutch PDK transmission, eliminating the manual option.

Porsche assured that the new engine, transmission, and chassis would broaden the GT3’s capabilities, making it more suitable for daily use while maintaining its renowned driver engagement and track performance.

The fifth-generation 991.1 911 GT3 was a complete redesign. It featured a 475hp 3.8ltr boxer engine, a power-to-weight ratio of 3.0 kg/hp, and a top speed of 315 km/h. It could accelerate from 0 to 100 km/h in 3.5 seconds and lapped the Nürburgring Nordschleife in under 7:30 minutes. Notably, it introduced active rear-wheel steering in a production Porsche and offered optional full LED headlights.

The new 911 GT3 retained its race-ready characteristics while enhancing driving dynamics and practicality. Its 3.8-liter engine, producing 475 hp at 8,250 rpm, was based on the 911 Carrera S engine but featured unique components like titanium connecting rods and forged pistons, allowing it to rev up to 9,000 rpm. The PDK transmission, inspired by sequential racing gearboxes, added performance advantages.

Active rear-wheel steering improved precision and agility by steering the rear wheels in the same or opposite direction of the front wheels depending on speed. Additional features included an electronically controlled, fully variable rear differential lock, dynamic engine mounts, and a new all-aluminium chassis adjustable by height, toe, and camber. The 20-inch forged alloy wheels with central locking enhanced road contact.

The 991.1 GT3, based on the light yet stiff hybrid steel-aluminium body of the 911 Carrera, featured independent front and rear parts and a wider rear axle area. The large, fixed rear wing contributed to its exemplary aerodynamics, combining low air resistance with increased downforce. The 991.1 GT3 set new performance benchmarks. It could reach 100 km/h in 3.5 seconds, 200 km/h in under 12 seconds, and had a top speed of 315 km/h in seventh gear. It completed the Nürburgring Nordschleife in under 7:30 minutes, underscoring its impressive capabilities.
