Press Release :
New for 2007, the Pontiac G5 coupe delivers Pontiac performance and style in a compact package that offers a surprising degree of standard and optional features in an entry-level model.
The G5, available in base and GT models, carries progressive Pontiac styling, with its twin-port grille, clean lines, white-faced sport gauges and standard rear spoiler. Built on GM’s global small car platform, both models are powered by GM Powertrain’s Ecotec premium four-cylinder engines. The base model features a standard Ecotec 2.2L I-4 that produces 148 horsepower (110 kW) and 152 lb.-ft. of torque (206 Nm). The peppier GT produces 173 horsepower (129 kW) and 163 lb.-ft. of torque (221 Nm)* with its standard Ecotec 2.4L I-4 with variable valve timing.
The G5 is equipped with standard Getrag F23 five-speed manual transmission, known for smooth shifting, or customers may opt for the convenience of the 4T45 electronically controlled four-speed automatic transmission. The 4T45 uses the new Dexron VI fluid and is ‘filled for life,’ meaning there is no scheduled maintenance required for the transmission under normal operating conditions.
Standard features
The G5 models have spacious, five-passenger interiors that reflect a focus on ride comfort, with quality materials and stylish appointments throughout. The base model comes with a variety of standard features including air conditioning; power locks, windows and door locks; carpeted floor mats; and four cupholders (two in front, two in rear). Available features include antilock brakes; head curtain side impact air bags; leather appointed seats; OnStar; seven-speaker Pioneer Sound System with 10-inch subwoofer; XM Satellite Radio; 6-Disc in-dash CD changer; cruise control; traction control; remote start; sunroof; cargo net; body-side moldings; fog lamps; leather-wrapped steering and shift knob; and 16-inch custom spoke or aluminum wheels.
Standard equipment on the GT model includes ABS, 17-inch aluminum wheels, sport rocker moldings; chrome exhaust tip; fog lamps, cruise control, leather-wrapped steering wheel with audio controls, leather-wrapped shift knob and cargo net.
Either model is available in nine different exterior colors.
Dynamic driving experience
The G5 is designed to deliver a dynamic driving experience for which Pontiacs are known. The vehicle uses a MacPherson strut-type front suspension, semi-independent torsion beam rear suspension, and front and rear stabilizer bars for more exact body roll control. Suspension tuning for each model, including steering feel, spring rate and stabilizer bar diameter, is dialed in to provide distinct driving and handling characteristics. Two suspension settings are available:
FE1 suspension – standard on the base model, it provides a smooth ride and includes a 19-mm front stabilizer bar and a 16-mm rear stabilizer bar
FE3 suspension – standard on GT, it delivers a firmer, more direct ride and includes 22-mm front and rear stabilizer bars, four-wheel disc brakes, monotube shocks and 17-inch wheels and performance tires
The G5′s strut-type front suspension is compact yet provides long wheel travel, with 90 mm of compression travel and 87 mm of rebound, which is substantially more than most competitors and enhances overall ride and handling. Monotube rear shocks are used for a more precise road feel. L-shaped front control arms contain a forward pivot bushing, which transmits most of the cornering force, and a larger, high-damped composite rear elastomeric bushing that allows rearward movement to minimize harshness from road surface impacts.
The direct-acting front stabilizer bar connects to each strut for precise steering response and improved cornering agility with decreased body roll. All front suspension components are mounted to a new, rigid cradle assembly comprised of four large hydroformed steel tubes and two side members that are integrally welded to front and rear cross members. The cradle is mounted to the G5′s space frame at four widely spaced points.
The G5′s torsion beam rear suspension provides excellent ride and handling, while maximizing interior space. A hydraulic rear suspension bushing is employed on the FE1 suspension to improve the ride and suppress road noise. Rear wheel travel, at 126.5 mm in jounce and 68.5 mm in rebound, is longer than most vehicles in the segment.
Engine specifics
The base model G5 is powered by a 148 horsepower Ecotec 2.2L I-4 while a 173 horsepower Ecotec 2.4L I-4 is standard on the GT. Although each Ecotec engine has distinct hardware differences and performance characteristics, all share the Ecotec family’s solid basic architecture and all-aluminum construction with:
Dual overhead camshafts (DOHC) and four valves per cylinder
Twin counter-rotating balance shafts
Low-friction, roller-finger follower valvetrain with hydraulic lash adjusters
Zero-maintenance chain camshaft drive
Extremely compact dimensions and low mass
Direct mounting of all accessories to the engine structure to eliminate common sources of noise, vibration and harshness
Full circle transmission attachment is more rigid than most four-cylinder powertrains for reduced noise and vibration
GM Oil Life System for optimum oil change frequency
No routine maintenance apart from oil/oil filter changes
Catalyst located close to the exhaust manifold to speed catalyst ‘light-off’ and reduce hydrocarbon emissions
Innovative cast-in oil filter housing eliminates crawling under the car to perform oil changes. The design also eliminates throwaway oil-filter ‘cans’ that retain used oil that typically ends up in landfills
Safety features
The rigid body structure that lays the foundation of G5′s dynamic driving experience also reinforces its safety. In addition to the solid unibody structure, dual-stage air bags are standard and side head curtain air bags are available. Front seat-belt pretensioners, rear center shoulder belts and the LATCH child seat retention system are also standard equipment.
OnStar-equipped G5 models feature dual-mode (analog-digital) equipment. OnStar’s digital equipment also includes enhanced hands-free voice recognition capabilities including more intuitive continuous digit dialing and improved voice recognition accuracy. Using the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Hands-Free Calling that allow drivers to make and receive voice-activated phone calls using an externally mounted antenna for greater reception.
The OnStar service available on the 2007 G5 includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to the participating 911 centers to help them dispatch the appropriate life-saving personnel and equipment to crash scenes faster.
