2005 PONTIAC GTO: THE NEW GOAT GETS MORE MUSCLE

GTO – the original muscle car – was re-introduced last year and returns with more power and style for 2005. A new LS2 6.0L V-8 engine replaces the LS1 5.7L engine, bringing with it an increase in horsepower and torque.

The '05 GTO packs 400 horsepower (298 kw) – up from 350 horses (261 kw) – and 400 lb.-ft. of torque (542 Nm), up from 365 lb.-ft. (495 Nm). Transmission choices are the same as the '04 model's: The Hydra-Matic 4L60-E four-speed automatic is standard and the Tremec six-speed manual is optional. GTO's more powerful engine should lower the 0-60 time to less than 5 seconds.

Enthusiasts will immediately spot the brawnier '05 GTO, thanks to new badging and a revised rear fascia that incorporates a new dual-exhaust system – it splits the GTO's two outlets, routing them to opposite sides of the rear fascia. The exhaust tips are polished for a more refined appearance.

Also available is a new hood design incorporating a pair of stylish air scoops. The scoops draw fresh air in to the GTO's engine compartment.

The badges identifying the '05 GTO's bigger V-8 include a '6.0' badge on the trunk lid and revised 'GTO' fender badges, which now incorporate '6.0 Litre' designations. The original 1964 GTO also wore '6.0 Litre' fender badges, but at a time when almost every other American manufacturer referenced engine size in cubic inches.

Along with the GTO's power increase comes improved braking performance from larger brake rotors, calipers and pads. The calipers are painted red and the front calipers feature the GTO logo.

Additional changes to the '05 GTO include two new colors (blue and grey), as well as driver foot rest. A line of regular production accessories (RPAs) based on the 2004 GTO Performance Plus SEMA concept vehicle is scheduled for start-of-production availability. The accessories include a tall rear spoiler, front and rear fascia extensions, rocker molding extensions and grille inserts. As part of GM's RPA program, the accessories can be ordered and installed on the vehicle prior to delivery.

LS2 details

Compared to the Gen III-based LS1, the 2005 GTO's LS2 V-8 incorporates several significant changes to help improve performance. The block is an all-new casting with cylinder bores measuring 4.00 inches (101.6 mm) in diameter. The cylinder heads and camshaft are revised, too, to deliver the airflow necessary to complement the engine's larger displacement. Other changes include:

• New aluminum block casting with revised oil galleries and provisions for external knock sensors – external sensors improve serviceability

• Camshaft lift increased to take advantage of increased cylinder head flow

• Camshaft sensor relocated from the rear of the block to the front of the block provides room for new oil galleries

• Flat-top piston design with lower ring tension reduces friction

• Piston floating wrist pins help quiet the engine

• More efficient ignition coils require less energy to provide a comparable spark

• Compression raised to 10.9:1

• Larger, 90-mm single-blade throttle body

• Reduced-mass water pump design with improved sealing capability

• Engine 'redline' raised to 6500 rpm

• Revised and more powerful engine controller incorporates all electronic throttle control functions.

• Balanced environment and safety

The new GTO is a contemporary performer. Its traits include impressive cornering abilities, a smooth ride and surprising comfort. The drivetrain rides on a 109.8-inch (279-cm) wheelbase, with a low stance that enhances the wide-track feel behind the wheel. The front track measures 61.4 inches (156 cm) and the rear track is 62.1 inches (158 cm) wide.

The fully independent suspension features MacPherson struts in front and a semi-trailing arm design in the rear, with specially tuned strut valving and spring rates. Direct-acting stabilizer bars and a variable ratio power steering system also are tuned to provide a sporty feel and increased driver feedback. Seventeen-inch alloy wheels and performance tires are matched to the performance-tuned suspension. Traction control and a limited slip differential also come standard.

The GTO's premium interior is accented by a harmonious blend of details, complementing its dynamic driving experience. All-leather seating, as well as a leather-covered steering wheel and shifter knob, immediately conveys luxury, while items such as stainless steel sill plates, metallic-look steering wheel styling, satin nickel-look accent trim, and racing-inspired drilled metallic pedals add sportiness to the environment.

The front and rear sports seats are configured in a traditional 2+2 configuration, with side bolsters and the 'GTO' name embroidered on the front seats. Interior seat and trim colors may be coordinated to the exterior color, with red, blue, purple and black interiors available. This splash of color extends from the seats to the door inserts to the lower part of the instrument panel to the gauge cluster.

Every GTO comes well equipped with a thoughtful package of interior amenities and safety features, including:

• Air conditioning

• Blaupunkt 200-watt audio system with six-disc in-dash CD changer and 10 speakers

• Console with storage compartment, accessory power outlet and two cupholders

• Cruise control

• Rear defogger

• Power door locks with lockout protection

• Programmable keyless entry with laser-etched key for added security

• Eight-way power adjustable driver and front passenger seats with power-assisted rear seat access feature

• Tilting and telescoping adjustable steering wheel

• Power windows with driver and passenger express-down feature

• Daytime running lamps with automatic headlamp control

• Theft and content deterrent system.

The integrated driver information center located below the instrument cluster includes readouts for average speed, average miles per gallon, trip odometer, trip time remaining, trip distance remaining, fuel used and instant fuel mileage. There's even a stopwatch feature and a user-programmable overspeed alarm.

Safety belts remain the primary and most effective form of occupant protection. All seating positions in the 2005 GTO have three-point safety belts. Retractors for front outboard seating positions have built-in load limiters that allow a controlled amount of give in the belt, thereby reducing the peak load on the chest during the 'ride down' in a crash.

Dual frontal air bags are standard and GTO is equipped with child seat anchors.

SC Incorporated, a full-service specialty-vehicle design and development partner for automotive manufacturers, today unveiled an enhanced version of the Pontiac GTO. The vehicle made its world premiere at the North American International Auto Show (NAIAS) in Detroit at ASC's press conference at the show.

The Yellow Fire Pearl-colored ASC GTO Stinger features several new, aggressive-looking body panels made using both ASC's RIMForm™ low-investment composites process and ASC's OmniCarbon™ carbon-fiber process for low-volume production as well as a short-throw Tremec® 6-speed transmission, a scooped hood, a state-of-the-art Sony Xplod® sound and DVD system and a custom Borla® 'cat-back' dual exhaust. A Magnuson supercharger on the concept unveiled here today has the potential also to take the horsepower to 550 ponies (and the 0-60 mph number to 4.3 seconds).

'The GTO Stinger is a Goat with a lot more ‘billy,'' said Jeff Steiner, ASC's executive vice president and chief marketing officer, referring to the Pontiac GTO's longtime street moniker. 'We believe there's a lot of interest from the American consumer in a GTO with the Stinger's kind of aggressive stance and strong visual appeal to complement the GTO's strong stock powertrain. Our vision is to test the market interest in this concept as a potential ASC dealer-upfit offering. We will be looking for input from both dealers and consumers to determine the level of interest, suggested product content and potential price points. Based on feedback we receive, we will determine any production plans for the vehicle.'

ASC has a long history of performance-vehicle upfitting. In the late ‘80s, the company oversaw all vehicle integration for the classic ASC McLaren Buick Grand National GNX model, recently named by Automobile magazine as one of the '100 Coolest Cars' of all time. In the ‘90s, ASC provided the custom composites hood and other components that helped the Pontiac Firebird TransAm WS6 model sell almost 40,000 units over five years, versus an original plan of just 6,500 units over three years. And, more recently, ASC has displayed its ongoing heritage as a low-volume manufacturer with its production of the Dearborn Deuce Convertible™, winner of two awards at the 2004 Specialty Equipment Manufacturers Association show—'Best-Engineered Product' and 'Best Street-Rod Product' runner-up. To date, more than 250 Dearborn Deuce Convertible™ units have been sold. They are built at its Reeck Road Assembly Plant in Southgate, Mich.

ASC's RIMForm™ and OmniCarbon™ Processes

Low-volume derivative programs like the ASC Stinger GTO are made commercially viable, according to ASC, through the use of proprietary low-investment tooling and manufacturing methods developed by the company.

The vehicle's RIMForm™ composite components include: an all-new hood with dual functional scoops; all-new, aggressive-looking wheel flares, front and rear; custom two-piece fascias, front and rear; and custom two-piece rocker panels.

Its OmniCarbon™ components include: a 'stinger'-style spoiler with carbon-fiber appliqué on deck lid; custom carbon-fiber fascia inserts; carbon-fiber appliqués on both exterior mirror surrounds.

Continuing with the theme, interior appointments include custom leather seats with a vertical carbon-fiber-look inserts and yellow racing stripes down the seat centers; a carbon-fiber-look rear-seat 'waterfall' area between the rear seats; and carbon-fiber-look door trim on both doors.

Topping off the package are custom honeycomb-mesh grille inserts; custom 4' exhaust tips; fog lamps with custom aluminum trim; 19-inch Axis Hiro® anthracite-colored wheels, front and rear, shod with Dunlop SP Sport™ 9000 tires; Wilwood Engineering® 13' front with 6 piston calipers and 12' rear brakes with 4 piston calipers; and a six-speaker Sony Xplod® multimedia entertainment system, including an 7 1/2-inch dash-mounted LCD DVD screen, providing state-of-the-art entertainment in the interior.

'We've looked at every aspect of the vehicle, starting with exterior styling and interior enhancements but also the extra performance items you see on the Stinger,' said Marques McCammon, ASC's director of business and product planning. 'All in all, we think there are several different package variants that are possible with this vehicle that no GTO enthusiast, or would-be enthusiast, can ignore. We at ASC will definitely be interested in gauging the public's reaction to this car at the show next week.

'Thanks to ASC's low-investment, quick-to-market RIMForm™ and OmniCarbon™ processes, components of the Stinger, or the entire package itself, could be ready for production in as little as nine months,' continued McCammon.
