Differences Between GT3, GT4, and Other GT Classes

Back to: Multiclass Racing

GT3 Cars:

• Higher downforce, better braking performance.
• More electronic assists (ABS, Traction Control).
• Faster acceleration and higher top speeds.
• More aggressive aerodynamics.
• Example: Ferrari 296 GT3, Porsche 911 GT3 R, BMW M4 GT3.

GT4 Cars:

• Less downforce and lower top speed.
• More similar to road cars with fewer aerodynamic aids.
• Requires smoother driving techniques due to less grip.
• Example: Aston Martin Vantage GT4, McLaren 570S GT4, BMW M4 GT4.

Other GT Classes (GTE, GTP, GT2, etc.):

• GTE (formerly in IMSA/WEC): Higher power than GT3 but with no ABS.
• GT2 (SRO GT2): More power than GT3 but less downforce.

📌 Key Takeaway: GT3 cars must navigate traffic while maintaining lap time, and GT4 drivers must focus on being predictable for safe overtaking.
