Porsche 911 GT3 Touring Receives 992.2 Mid-Cycle Update with Engine Adjustments
Key points
- 911 GT3 Touring gets 992.2 mid-cycle update.
- Engine torque reduced by 15 lb-ft due to emissions regulations.
- GT3 RS cylinder heads and camshafts used to maintain 502 hp.
- Final-drive ratio shortened by 8% for harder acceleration.
Updated GT3 Touring Maintains Core Design
The latest Porsche 911 GT3 Touring, following its 992.2 mid-cycle update, largely adheres to its original design philosophy. This includes its naturally aspirated 4.0 L flat-six engine, which revs to 9,000 rpm, and a track-focused chassis. The Touring model continues to offer a more understated aesthetic by replacing the standard GT3's fixed rear wing with a deployable spoiler from the Carrera.
Engine Adjustments Due to Regulations
The updated GT3 Touring's 4.0 L flat-six engine produces 502 hp (375 kW) and 331 lb-ft (449 Nm) of torque. This torque figure represents a 15 lb-ft reduction compared to the previous model. This change was necessitated by stricter European emissions and noise regulations, which required the addition of two catalytic converters and two gas particulate filters to the exhaust system.
Performance Compensation Measures
To counteract the flow restriction caused by the new exhaust components and maintain peak horsepower matching the 992.1 GT3, Porsche engineers incorporated cylinder heads and camshafts from the GT3 RS. Additionally, the final-drive ratio was shortened by 8 percent. This modification aims to trade a slight reduction in top speed for more aggressive acceleration.
Standard Performance Hardware Retained
The GT3 Touring continues to feature its standard suite of performance hardware. This includes massive brakes, rear-axle steering, a GT3-specific suspension, and an active sport exhaust system. Power is exclusively sent to the rear wheels, with transmission options including a seven-speed PDK dual-clutch automatic or a six-speed manual gearbox.
