Passage presented a re-planned 2005 model year Mustang at the 2004 North American International Auto Show, codenamed “S-197”, that depended on the new D2C stage. Created under the bearing of Chief Engineer Hau Thai-Tang, a veteran specialist for Ford’s IndyCar program under Mario Andretti, and outside styling architect Sid Ramnarace, the fifth-age Mustang’s styling echoes the fastback Mustang models of the last part of the 1960s. Passage’s senior VP of plan, J Mays, called it “retro-futurism.” The fifth-age Mustang was produced at the Flat Rock Assembly Plant in Flat Rock, Michigan.
For the 2005 to 2010 creation years, the base model was fueled by a 210 hp (157 kW; 213 PS) cast-iron square 4.0 L SOHC V6, while the GT utilized an aluminum block 4.6 L SOHC 3-valve Modular V8 with variable camshaft timing (VCT) that delivered 300 hp (224 kW; 304 PS). Base models had a Tremec T5 5-speed manual transmission with Ford’s 5R55S 5-speed programmed being discretionary. Programmed GTs additionally highlighted this, yet manual GTs had the Tremec TR-3650 5-speed.
The 2010 model year Mustang was delivered in the spring of 2009 with an overhauled outside — which included successive LED taillights — and a decreased drag coefficient of 4% on base models and 7% on GT models. The motor for base Mustangs stayed unaltered, while GTs 4.6 L V8 was reexamined bringing about 315 hp (235 kW; 319 PS) at 6000 rpm and 325 lb⋅ft (441 N⋅m) of force at 4255 rpm. Other mechanical highlights included new spring rates and dampers, footing and dependability control framework standard on all models, and new wheel sizes.
