13. 1996 Ford Mustang GT 4.6
Although the fourth-generation Mustang GT was introduced in late 1993 as a 1994 model, it had the old 5.0-liter V8 as the only engine option. However, in 1996, Ford introduced a brand-new modular V8 with 4.6-liter displacement and a very slight power upgrade from the previous year’s model. The 4.6-liter delivered 215 hp and 285 lb-ft of torque.
The critics say that this engine wasn’t very powerful in stock form, and it didn’t respond well to modifications. But it was well-loved by customers and was also a solid performer on the street compared to other muscle cars of the period (via Motor Trend).
