Review of the 2005 Pontiac GTO

  • Old-school GTO fans may not like the Euro-style looks of the modern-day incarnation, but there's no denying that under its skin beats the heart of a true muscle car.

    Powerful V8, rear-wheel drive, tight build quality, loaded with standard features.

What's New for 2005

The 2005 Pontiac GTO receives a new engine -- the 6.0-liter LS2 V8. The new V8 produces 400 horsepower, up from 350, and 395 lb-ft of torque, up from 365. More rumble comes from a new split dual-exhaust system, and new exterior options include two new colors and an available hood scoop.


The GTO legend started back in 1964, when Pontiac offered Tempest/Le Mans buyers a GTO option package. That performance-enhancing option proved so popular that the GTO became its own model and is often credited as the first true "muscle car." Although some purists would say the "real" GTO died in 1973, the GTO name lasted until 1974 when the car was based on the Pontiac Ventura, itself a thinly disguised Chevy Nova. With only 200 horsepower and distinct Nova looks, it's easy to see why many do not consider the '74 to be a true GTO. As the performance dwindled, so did the popularity of the GTO and sales swiftly declined. The introduction of the more realistic "net" horsepower rating in the early '70s couldn't have helped, as it was surely difficult for local dealers to explain why a '71 GTO with a 400-cubic-inch V8 produced only 255 hp. By 1972, some of the GTO's former glory was restored, but the dark cloud of emissions control and government-mandated bumpers loomed large, and the once-proud Pontiac became nothing more than just another GM clone. Miraculously, GM has resisted the urge to slap the GTO badge on anything since 1974. It seems all the more curious given how fast and loose Chevrolet plays with its once-coveted "SS" moniker. We can't help but wonder how close the first Grand Prix GTP came to being labeled a GTO, but thankfully those in charge at Pontiac realized that "GTO" shouldn't be within a mile of a front-wheel-drive V6 automobile -- V8s only, please. GM was able to deliver on that promise thanks to a little help from its Holden division in Australia. The Holden Monaro CV8 is the basis for the modern-day GTO, and like GTOs of the past, the new version is a 2+2 coupe. The Holden received styling revisions to make it look more like a Pontiac. The resulting twin grille and a slightly familiar rear-end treatment say "Pontiac" even from 20 yards away. Initially, the GTO was powered by GM's LS1 V8 making 350 hp. For 2005, Pontiac slid the LS2 6.0-liter V8 under the hood, good for 400 hp. Blasting from zero to 60 in less than 5.5 seconds and blitzing the quarter-mile in under 14 ticks means a 2005 Pontiac GTO will simply embarrass nearly any old Goat you could name. A four-speed automatic transmission is standard, and all GTOs come with four-wheel antilock disc brakes, as well as a limited-slip rear end and traction control. An optional six-speed manual transmission only adds to the fun, and with a fully independent, performance-tuned suspension and 17-inch wheels wrapped in performance tires, the car is able to hold its own in the corners while still delivering a relatively supple ride.

Body Styles, Trim Levels, and Options

The 2005 Pontiac GTO is offered as a 2+2 sport coupe in one generously appointed trim level. The standard features list includes full leather trim (seats, steering wheel, shift handle); a premium Blaupunkt audio system with an in-dash six-disc CD changer; keyless entry; eight-way power-adjustable front seats; a trip computer; power windows, locks and mirrors; air conditioning; cruise control; and 17-inch aluminum wheels. Aside from choosing a transmission, there are no additional options.

Powertrains and Performance

There is only one engine available on the 2005 Pontiac GTO -- a 6.0-liter V8 rated at 400 horsepower and 395 pound-feet of torque. The standard transmission is a four-speed overdrive automatic, but a six-speed, close-ratio manual transmission is available as an option. Regardless of which transmission is selected, all GTOs come with a limited-slip differential and electronic traction control.


All GTOs come standard with four-wheel antilock disc brakes, electronic traction control, multistage front airbags and an emergency mode that shuts down the vehicle's systems and unlocks the doors in the event of an airbag deployment. Side airbags are not available, nor is stability control. The GTO has not been crash tested.

Interior Design and Special Features

Unlike the original GTO, this modern-day version is no stripper. Comfortable leather-trimmed seats; a 200-watt, 10-speaker sound system; and a comprehensive trip computer all come standard. The overall design is straightforward with large analog gauges and an easy-to-use climate control system. Access to the rear seats is tight as you might expect, but they are quite comfy once you're seated.

Driving Impressions

On the street, the 2005 Pontiac GTO has a luxury carlike ride quality, and when pushed a bit, it seems to handle predictably and respectably, despite a fair amount of body roll. But when driven more aggressively, the car feels heavy and the steering a little slow and numb. Blazing engine performance and powerful brakes, however, showcase true muscle car roots.

2005 gto sport appearance package

Vehicle: 2005 Pontiac GTO 2dr Coupe (6.0L 8cyl 4A)

I bought an 05 GTO with 18K miles with the sport appearance package or SAP which includes quad exhausts, cool side skirts, SAP front bumper and grills. Paint is Cyclone Gray. Added a JHP color matched gage pod for volts and engine oil pressure, chrome tail lights with red LED's, chrome aluminum wheels, GM Performance high flow oil pump, headers and 160 degree therm. Use ALT friction modifier to engine oil (6 oz.) and 1 oz. to power steering. ALT claims 48% reduction in friction. ALT is Advanced Lubrication Technology. Removed rear spoiler and painted trunk lid. At 54K miles, replaced rotors and pads and replaced auto trans fluid and differential fluid with GM friction modifier.

Vehicle: 2005 Pontiac GTO 2dr Coupe (6.0L 8cyl 4A)

05' GTO M6 I originally bought this car because I got tired of "fix-her-up" lemons and Ricky racers. What I didn't expect is to fall in love with it at first site. I'm a gear head at heart and at time I forget to do work the car needs because I don't like to work on it. Not that its hard work or difficult,I just rather be driving. No car has made me feel this way up to now. But I assure you,soon enough I will do plenty of engine mods. For the money I really feel when it comes to used american muscle/sports cars that do everything "well". You really can't find a better car in market,I'm sure of it.

Fast, comfortable, reliable.

Vehicle: 2005 Pontiac GTO 2dr Coupe (6.0L 8cyl 4A)

I have owned my '05 GTO since new, It has a 6 spd man trans & 30k miles on it. I have changed the exhaust system, added a CAI and stereo. The car has not cost me a dime other than gas & oil changes. It has never been to the dealer for a repair, not once. I have had a bit of trouble making back tires last, it's so much fun to drive. On the highway, it's a pleasure to drive. It's very smooth and quiet, it gets 24mpg on the highway and about 15mpg in the city. I average about 17mpg in mostly city driving. These are the most comfortable seats I have ever sat in, they are both 8 way power adj. w/man lumbar adj. There's a lot of rear seat room too, but it's difficult to get in/out of.

This car is a screamer, I put a k/n CAI, and a borla exhaust in my car. Now it sounds great, it sounded good when i first got it, and could lay down some rubber but now i could burn the tires right off if i wanted too (not like i couldn't when it was stock). last year i went on a trip to Colorado and the ride just never gets old its such a comfortable ride i Just love this car. Everybody should have one!!

Gto and the driver of

Vehicle: 2005 Pontiac GTO 2dr Coupe (6.0L 8cyl 4A)

Coming back from a visit from Afghanistan I wanted a new vehicle. I was debating between three cars. A 2003 Ford Mustang Cobra, 2005 Corvette C-6 or a 2005/06 GTO. The Vette and the GTO offered 400Hp of true aspirated engine. The Cobra offered 390 with the factory Super Charger. The GTO had four seats. Also honestly, how many GTO's do you see compared to the mustang and Vette? My choice was obvious. I needed to put the test on it. I drove it from North Carolina to California and back. No problems the entire trip. When I got back there were some electronic issues. Nothing a few hundred cant fix. I later invested about $10,000 into the engine to make it a real 535 RWHP beast. I love my GTO.
