As fiery and bold as the famous sunbird is the newest 2005 Pontiac Sunfire. It came as replacement for the Pontiac Sunbird and together with the new name are added enhancements and improvements on the vehicle' style and performance. ISV, ISA, ISB and ISC are the available models. Standard on ISV is a 2.2L DOHC 140-horsepower Ecotec engine matched with a Getrag five-speed manual transmission. Other standard auto parts and accessories are PASSLock theft-deterrent system for security against unwelcome users, rear deck lid spoiler for much better road grip and easier turning and cornering and gauge cluster which includes speedometer, odometer and tachometer to give first hand information regarding the car's performance.

Pontiac Sunfire ISB is equipped with the same engine but paired with a different transmission, the four-speed automatic transmission with improved traction system that can only be used through an Anti-Braking System. Easier manipulation of the car's power train system can be achieved by means of the responsive tilt steering wheel. The entertainment showcase includes the standard AM and FM stereo that features the improved Audio System that features a CD player with MP3 capabilities. Also offered is an XM Satellite radio that can give clear quality sound anywhere the driver or passengers may be. They can stay in contact with their favorite radio programs, the latest events, sports, entertainment and other news to keep them updated. Together with these features is an optional Monsoon sound system that includes advance amplifiers and custom speakers.

Meanwhile, the sleek and fiery Pontiac Sunfire ISC comes in flaming red color tone equipped with four-wheel Anti Braking System, cruise control, security package, controlled cycle wipers and muscular 15" cast aluminum wheels. Other packages offered to add amenities and much improved performance are Convenience Package, Power Package, Protection Package, Security Package, Sport Appearance Package, Sport Interior Package and Sun and Sound Package.
