The SRT-4 model, introduced at the Chicago Auto Show in February 2006, is a replacement for the original Neon-based SRT-4 produced by Chrysler's Street and Racing Technology group. It is a hatchback set to compete with the likes of the Volkswagen GTI and the Mazdaspeed 3. It features a 2.4-liter DOHC 16V Turbocharged I4 with dual variable valve timing (DVVT). It produces 285 hp (213 kW) at 6,400 rpm, and 265 lb·ft (359 N·m) of torque at 5,600 rpm using the Mitsubishi TD04HL4S-20 turbo. Edmunds put it on the dyno and it resulted in 281 hp (210 kW) and 261 lb·ft (354 N·m) of torque. The engine is mated to a Getrag six-speed manual transmission, and utilizes a front-wheel drive drivetrain. The Caliber SRT-4 utilizes a high-performance MacPherson strut front suspension, and a performance-tuned multilink rear suspension. The SRT-4 uses large 340 mm (13.4 in) vented front disc brakes (from the Dodge Charger Police Pack version) with dual-piston calipers and 302 mm (11.9 in) rear single-piston disc brakes. It features four-wheel antilock brakes, with electronic assistance. The wheels are 19 inch, five-spoke, SRT-stamped, painted aluminum. The car features Goodyear performance 225/45R19 tires. Package options include polished wheels, GPS navigation, bluetooth, a block heater, and rear hat-rack
