2003 Ford Mustang GT: The Ultimate Guide

Welcome to the definitive guide for the 2003 Ford Mustang GT. If you're looking for detailed information on this iconic muscle car, you've come to the right place. We'll cover everything from performance specs to common issues and maintenance tips to help you get the most out of your Mustang.

Engine and Performance

The heart of the 2003 Ford Mustang GT is its legendary 4.6L 2-valve SOHC V8 engine. This powerhouse, often referred to as the ""Bullitt"" engine due to its shared architecture, produced a respectable 260 horsepower and 302 lb-ft of torque when new. This was a significant upgrade from previous models, offering a thrilling driving experience.

Horsepower and Torque

Ford engineers tuned this V8 for a satisfying blend of everyday drivability and exhilarating performance. The torque curve was designed to provide strong low-end grunt, making it feel responsive off the line and capable during spirited driving.

Transmission Options

Buyers had the choice between two robust transmission options: a 5-speed manual Tremec T-45 or a 4-speed automatic transmission. The manual offered a more engaging connection to the road, while the automatic provided convenience for daily commuting. — Houses For Rent In Villa Rica, GA

Rear Suspension

A three-link solid rear axle with a Panhard rod was used. While a solid axle can sometimes be a point of criticism for modern sports cars, Ford's tuning provided a competent platform for the GT's performance capabilities.
