2008 Pontiac G5 Overview

By Cars.com Editors
Vehicle Overview
Introduced for 2007, the Pontiac G5 coupe is virtually identical to the Chevrolet Cobalt, which has been around since 2005. The G5 is only offered as a coupe, and is available in base and GT trims. For 2008, the G5 receives standard satellite radio and standard side curtain airbags, as well as added standard features on the GT trim. The G5 competes with other compacts, such as the Ford Focus, Scion tC and Honda Civic.

Engines include a 2.2-liter inline-four-cylinder that makes 148 horsepower in the base model, and a 2.4-liter inline-four-cylinder that generates 171 hp in the G5 GT.

The G5 has more standard equipment than its Chevrolet sibling — power windows and remote entry are installed on base GTs but are optional in the Cobalt — but it also costs more.


Exterior
A double-cutout Pontiac grille differentiates the G5 from the Cobalt, but beyond that the differences are scant. A rear spoiler is standard, as are steel wheels. GT models upgrade to 17-inch alloy wheels, fog lamps and a sport-tuned suspension, though all G5s ride on a semi-independent rear setup rather than the fully independent rear some competitors have. New colors include Midnight Blue Metallic, Nitrous Blue Metallic and Dark Slate Metallic.

Interior
The G5's interior has a familiar look, with radio controls and other switches mounted on a vertical center stack. A three-spoke steering wheel sits ahead of chrome-ringed instrument pods. XM Satellite Radio is now standard on all G5 mo...

Interior
The G5's interior has a familiar look, with radio controls and other switches mounted on a vertical center stack. A three-spoke steering wheel sits ahead of chrome-ringed instrument pods. XM Satellite Radio is now standard on all G5 models, while GM's OnStar communication system is standard on GT G5s.

Standard equipment includes power windows and locks, as well as remote keyless entry, air conditioning and a CD stereo with an auxiliary input for iPods or other MP3 players. Upgrading to the G5 GT nets a leather steering wheel with audio controls; additional options include heated leather seats, remote vehicle start, a moonroof and a 228-watt, seven-speaker stereo.


Under the Hood
The G5's standard engine is General Motors' tried-and-true Ecotec inline-four-cylinder. It displaces 2.2 liters and generates 148 hp and 152 pounds-feet of torque. GT models upgrade to a 2.4-liter engine with variable valve timing, boosting output to 171 hp and 167 pounds-feet of torque.

A five-speed manual transmission is standard on both models, and a four-speed automatic is optional.


Safety
Four-wheel-disc antilock brakes are standard on the GT. Disc/drum brakes with optional ABS come with the base G5. Side-impact airbags are standard for all G5s. GT models come with GM's StabiliTrak electronic stability system.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
