Performance
| Power: | SAE 215 hp (160 kW) (2003 model) SAE 230 hp (170 kW) (2004–2005 models) In 2004, the SRT-4 received a power increase, with larger fuel injectors and a recalibrated engine computer. Manufacturer's specification when the SRT-4 was released was 230 hp (170 kW). However, several independent tests have produced results indicating 230-238 hp and 250-262 lb-ft that means the SRT-4 produces more power than the manufacturer claims. The flywheel power is estimated to be around 265-270 hp(194-198 kW) and around 285-300 lb-ft (386-406 N·m) |
|---|---|
| Torque: | 245 lb·ft (332 N·m) @ 3200-4200 rpm (2003 model) 250 lb·ft (339 N·m) @ 2400-4400 rpm (2004–2005 models) |
| 0-60 mph (97 km/h) time: | 5.6s (2003) 5.3s (2004, 2005) (Car and Driver) |
| Rev Limiter/Redline: | 6240 |
| 1⁄4 mile (400 m) time: | 14.1s (2003) 13.9s (2004, 2005) However, several independent tests have produced results of 0-60 mph 5.2s and 1/4 mile 13.7s @104.3 mph (167.8 km/h) (2004, 2005) |
| 1⁄4 mile speed: | 102 mph (164 km/h) (2003) 103 mph (166 km/h) (2004, 2005) |
| Top speed: | Car and Driver magazine achieved a maximum speed of 153 mph (246 km/h). However, several independent tests have produced results of a top speed of 160 mph (257 km/h) |
Braking consists of an ABS system with 11.0 in (280 mm) F vented/ 10.6 in (270 mm) R discs and single piston calipers (57 mm front/36 mm rear).
17 × 6-inch cast aluminum wheels with an offset of 43 mm, coupled with 205/50/17 Michelin Pilot Sport tires helped put the power to the ground on 2003 models, with 2004 and 2005 models getting BF Goodrich KDW2 tires. Even wider 225/45/16 BF Goodrich KDW2 tires on lightweight BBS racing wheels (40 mm offset) were offered on the ACR model in 2005. The standard 17 in (43 cm) wheels were purposely designed to look like aftermarket wheels, and the unique spoke pattern allowed for better airflow to the brakes. The design showed much similarity to the TSW VX1 wheels found on the 2001 concept supercharged Neon S-R/T.
In 2003, Dodge engineers built a special SRT-4 Extreme LightWeight using only factory performance upgrade parts from Mopar in conjunction with lightweight, carbon fiber body pieces (produced in-house) for weight reduction. The car weighed only 2,500 lb (1,100 kg) wet and was dyno'd at 360 hp (270 kW) and 383 lb·ft (519 N·m) (at the wheels) by SportCompactCar magazine. On drag slicks, it ran an 11.83-second pass at 123 mph (198 km/h) in 70 °F (21 °C) weather.

Famous quotes containing the word performance:
“True balance requires assigning realistic performance expectations to each of our roles. True balance requires us to acknowledge that our performance in some areas is more important than in others. True balance demands that we determine what accomplishments give us honest satisfaction as well as what failures cause us intolerable grief.”
—Melinda M. Marshall (20th century)
“So long as the source of our identity is external—vested in how others judge our performance at work, or how others judge our children’s performance, or how much money we make—we will find ourselves hopelessly flawed, forever short of the ideal.”
—Melinda M. Marshall (20th century)
“To vote is like the payment of a debt—a duty never to be neglected, if its performance is possible.”
—Rutherford Birchard Hayes (1822–1893)
