1999 Ford Mustang GT Welly 1:24











MUSTANG GT:
Following the base Mustang in December 1993, the Mustang GT was reintroduced in January 1994, featuring higher performance and better handling than the base Mustang or its 1993 predecessor. Ford carried over the 302 CID pushrod small-block V8 engine (called the "5.0 L" although its actual dispacement was 4.94 L) from the 1993 Mustang GT. Total output from the engine was 215 hp (160 kW; 218 PS) at 4200 rpm and 285 lb⋅ft (386 N⋅m) of torque at 3400 rpm. Mustang GTs could deliver zero to 60 mph (97 km/h) acceleration times in the high-six second range and complete a quarter-mile in about 15 seconds. The Mustang GT also featured a stiffer handling suspension, a 3.08:1 rear axle ratio (later changed to 3.27:1 or 3.55:1 depending on the transmission and model year), dual exhausts, and larger 16-inch (410 mm) wheels (compared to the base Mustang's 15-inch wheels). The 1994 Mustang GT was named Motor Trend Car of the Year.

For 1995, a one-year model referred to as the Mustang GTS was introduced. This was considered to be a "stripped down" version of the Mustang GT that included the performance parts of the GT model, but a minimum of non-performance related features, similar in concept to the 5.0 LX Fox-body. The 1995 GT was the last year of the 5.0 pushrod V8 engine.

In 1996, Ford dropped the 302 CID small block V8 that was in production since 1968 and introduced the Modular 4.6 L SOHC V8. These engines were produced at two different plants, Windsor and Romeo. A "W" in the VIN 8th digit indicates a "Romeo" engine, while an "X" indicates a "Windsor".

The Windsor and Romeo have subtle differences. Valve cover bolt patterns are one. Romeo has fewer bolts than the Windsor. Another difference is the front cover bolts. The Windsor uses 8 mm and the Romeo uses 10 mm bolts. The Romeo uses jack screws on the main caps and the Windsor uses dowels. The new engine produced 215 hp (160 kW; 218 PS) at 4400 rpm and 285 lb⋅ft (386 N⋅m) of torque at 3500 rpm, matching the output of its predecessor. For 1998, the 4.6 L V8 received a small increase in output, resulting in 225 hp (168 kW; 228 PS) at 4750 rpm and 290 lb⋅ft (393 N⋅m) of torque at 3500 rpm. This was achieved through PCM calibration and a modified fuel system. Though capable of matching or exceeding the older 302 V8's output, the 4.6 L V8 was criticized for delivering inadequate performance, particularly against the larger displacement of the OHV V8 used in the Mustang's chief rival, the Chevrolet Camaro.
