2005 PONTIAC BONNEVILLE: PERFORMANCE LÚXÚRY WITH THE EMPHASIS ON PERFORMANCE
Bonneville has been a leader in performance luxury since its 1957 debut. And wîth the introduction last year of the GXP model, the Bonneville returned to its V-8 roots. The Bonneville GXP is back for '05, along wîth luxurious and capable SE and SLE models – each model boasting a long list of standard and personalization features.
For 2005, the Bonneville SLE receives the smooth, refined styling of the GXP model, including new front and rear fascias, front and rear headlamps, foglamps, bodyside molding and rockers. The SLE also has standard 17-inch aluminum wheels.
GXP leads wîth performance
With an eight-cylinder heart and a look all its own, the Bonneville GXP is a performance leader. Refined styling, including specific front and rear fascias, headlamps, taillamps, exhaust outlets and rear spoiler, identifies the GXP at a glance, but the 4.6L DOHC 32-valve Northstar V-8 is the special model's defining character trait. Rated at 275 horsepower (205 kw) and 300 lb.-ft. of torque (406 Nm), the V-8-powered Bonneville GXP provides an exhilarating driving experience unlike any other in the front-wheel-drive, full-size sedan §egmènt.
To handle the V-8 engine's torque output, the engine is mated to the Hydra-Matic 4T80-E electronically controlled four-speed automatic transmission. (posted on conceptcarz.com)
Bonneville SE and SLE models equipped wîth the 3800 V-6 engine use the Hydra-Matic 4T65-E four-speed automatic. GXP and SLE models share exterior styling, but have different exhaust outlets, wheels, tires and spoiler.
The GXP's power is balanced wîth a performance-tuned handling package that includes a four-wheel independent suspension, StabiliTrak electronic stability system and an electronically controlled transaxle wîth a 3.71 final drive gear. Stopping power for the GXP is handled by standard four-wheel disc brakes wîth ABS. Also, 18-inch W-rated performance tires add cornering grip, while styled aluminum wheels enhance the vehicle's performance aesthetic.
StabiliTrak assists the vehicle in maintaining the driver's intended path by applying brake force at any corner of the vehicle independent of the driver's use of the brake pedal. StabiliTrak uses an accelerator pedal position sensor, a brake master cylinder pressure sensor and a §teering wheel angle sensor as inputs to interpret the driver's desired path and whether to decelerate the vehicle. StabiliTrak also uses these sensors plus a lateral accelerometer and yaw rate sensor to determine the vehicle's actual path. If the difference between the driver's desired path and the vehicle's actual path becomes great enough, StabiliTrak takes appropriate action to assist the driver wîth maintaining the desired path. If the vehicle begins to 'snowplow,' or understeer, StabiliTrak applies the appropriate rear brake to help turn the vehicle. If the vehicle begins to fishtail, or oversteer, StabiliTrak applies the outside front brake to straighten the vehicle. StabiliTrak is integrated wîth the traction control and ABS systems.
The GXP's interior is as luxurious as its mechanicals are performance-minded. Últralux suede inserts adorn the seats and door panels; the shifter handle is brushed aluminum; carbon-fiber trim is abundant and the interior switches are a rich ebony. Standard memory bucket seats on the GXP model include power lumbar and power recliner controls on the driver's seat. The GXP includes a center console wîth storage and rear heating/cooling outlets. Driver and front-passenger side-impact air bags and dual-zone climate control wîth individual climate settings for the driver and front passenger are standard wîth this top-of-the-line model.
A CD-cassette player and Monsoon eight-speaker sound system rivaling many great home systems are also part of the GXP.
Standard luxury in SE and SLE
The standard model Bonneville SE combines the performance of the 3800 Series II V-6, rated at 205 horsepower (153 kw) and 230 lb.-ft. of torque (312 Nm), wîth room to carry up to six passengers in comfort. This well-equipped model offers standard features like driver- and front-passenger air bags, a floor console and electronic cruise control. Bonneville SE also features power door locks, full instrumentation, remote keyless entry, rear-seat pass-through, an AM/FM stereo wîth CD player, a theft-deterrent alarm system, a tire-inflation monitor and power windows wîth an express-down feature for the driver and front passenger.
Bonneville SE owners who are lòòking for a higher level of content in their vehicle will find SE's 1SC Preferred Equipment Group ideal. It adds the 3.05 performance axle ratio, one year of OnStar Safe & Sound service, a leather-wrapped §teering wheel wîth audio controls, all-speed traction control, a six-way power driver's seat and front leather seating surfaces.
Drivers preferring to move up to the Bonneville SLE receive a standard driver information center, one year of OnStar's Safe & Sound service, 17-inch five-spoke aluminum wheels, all-speed traction control, heated power exterior mirrors, a 3.05 performance axle ratio and a rear deck spoiler.
XM Satellite Radio also is available on all Bonneville models. XM Satellite Radio (continental Ú.S. only) provides more than 120 coast-to-coast, digital-quality channels of original commercial-free music and premier news, sports and talk as well as advanced traffic and weather information for select major metropolitan areas nationwide. Consumers can subscribe to the basic service for $9.99 a month. In addition, GM customers wîth GMAC financing can choose to include the XM subscription in their car payments.
Safety belts remain the primary and most effective form of occupant protection. All seating positions in the 2005 Bonneville models have three-point safety belts. Inboard belts are mounted to the seats so the buckle moves wîth the seat during adjustments. 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.
Bonneville also has dual-stage frontal air bags for supplemental protection for front seat passengers. Dual-stage frontal air bags are designed to help reduce the risk of air bag-induced injury. When the air bag system's control unit detects an impact, it determines whether the crash is severe enough to trigger a deployment, and whether the primary amount of inflation is sufficient. The primary stage alone will deploy in most frontal impacts requiring the supplemental protection of an air bag, while a secondary stage is designed to deploy in more severe frontal collisions.
Seat-mounted side-impact air bags are available on Bonneville SE and SLE models; they are standard on Bonneville GXP. Bonneville also has pretensioners in the outboard front safety belt system that deploy at the same time as the frontal air bags to take up slack in the safety belt webbing. Pretensioners also help reduce the amount of occupant movement in the event of a crash to help reduce the risk of injury.
Bonneville also is equipped wîth LATCH (Lower Anchors and Tethers for CHildren) system anchors for child safety seats. This system provides two lower anchors and a top tether anchor to be used to secure a child seat to the vehicle seat structure. These anchorages are designed to make it easier to properly install compatible child safety seats.
All Bonneville models come standard wîth OnStar, featuring new, sixth generation hardware wîth digital and analog coverage. OnStar's Gen 6 hardware also includes upgraded hands-free voice recognition capabilities including more intuitive continuous digit dialing and improved voice recognition accuracy. OnStar is the leading provider of in-vehicle safety, security and information services in the Únited States and Canada. Úsing the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Personal Calling that allows drivers to make and receive hands-free, voice-activated phone calls using a powerful three-watt digital/analog system and external antenna for greater reception.Source - GM Corporation
To celebrate General Motors' 50th Anniversary 'Golden Jubilee', all stops were pulled out by the designers on the 1958 Pontiac Bonneville Sport Coupe, undoubtedly one of the flashiest of all 1950's vehicles. A one year only body was featured as a final staement by longtime GM styling chief Harley Earl before his retirement. The entire 1958 lineup litterly sparkled chrome. Unique two-tone exterior color combo's and delxue interiors were showcased on interiors on all 58 models from Chevrolet's, Pontiacs, Buick, Oldmobiles and Cadillacs. There motto for this year was ‘The Boldest Advance in Fifty Years!'
Semon E. 'Bunkie' Knudsen became Pontiac's new general manager in the summer of 1956 and soon after he hired Pete Estes and John DeLorean. Huge changes were in the works for Pontiac. First introduced as mainly a dealer promotion vehicle, that attempted to highlight Pontiac's new high performance image, the original Bonneville was a largy flashy convertible with a highly powered V8 engine generating 310 horsepower.
Originally introduced as a limited production performance convertible in the Pontiac Star Chief model range during the 1957 model year, the Bonneville eventually became its own series in 1958. Historically based of of the Cadillac DeVille, the Bonneville was built by the Pontiac division of General Motors from 1958 until 2005. Pontiac has been best known for its performance vehicles, especially since the introduction of the Bonneville I 1957. Perhaps a little flashier and faster than than a Chevrolet, it is still cheaper than an equivalent Oldsmobile or Buick. That has remained Pontiac's mission.
First appearing in 1954 on on a pair of bubble-topped GM Motorama concept vehicles called the Bonneville Special, the Bonneville name first entered the lineup as the Star Chief Custom Bonneville, which was a high-performance, fuel-injected luxury convertible late during the 57 model year. The very first Bonneville was a spectacular, chrome-laden convertible with a continental-style spare wheel mounting, fuel-injeted engine. It came with an eight-power front seat, underseat heater, degroster electric antenna, and many more unique and exclusive features.
During that first year, only a total of 630 units were produced. This small amount made it the most collectible Pontiac of all time, especially since it cost twice the amount of the star Chief convertible. The Bonneville has persisted, and remained as the division's top of the line model until 2005. Many speed records were being set at the Utah salt flats, and the name was created from the town of Bonneville, the place of much auto racing, and most of the world's land speed record runs.
The public must have liked both the car and its name became in 1958, a coupe was added into the lineup as Bonneville expanded into its own series. In this year it paced the Indianapolis 500. Offering 225 hp an 285 hp V8 engines, the Bonneville sat atop the Pontiac range, also offering a deluxe steering wheel, unique upholstery and chrome wheel covers. The Bonneville also featured wraparound windshields and rear window, two-toning on the roof and long striking sidespear plus chrome hash marks placed on the front fenders.
During its third year, the ‘59 Bonneville gained a 4-door bodystyle along with a nearly complete line in itself. The Pontiac Wide-Track was born in 1959, when all Pontiac makes and models received new chassis with ‘wide-track' stance. During this year, the introduction of two of Pontiac's greatest marketing inspirations were showcased, the split grille, and the Wide Track slogan, both are still part of Pontiac's image to this day.
Sales peaed in 1966 at 135,401 units sold. In 1969, the main highlight became the new V8 engine that provided 360 horesepower. Considered Pontiac's most expensive and most luxurious model throughout the 1960s, the Bonneville was extremely instrumental in moving Pontiac to third place in sales from 1962 until 1970. Bonneville's constantly received updates, changes and restyling, along with new features for all of its trim models throughout the 1970's.
During the early 1970's, the Grand Ville name was being used for Pontiac's highest-price model, and though the Bonneville was de-emphasized slightly, it never went away. In 1976, the Bonneville emerged in the top spot. This was the final year before the down-sized full-sized Pontiacs began to appear in 1977.
The Bonneville nameplate was quite abruptly moved from a full-size vehicle to the mid-sized car in 1982. The mid-sized car was previously known as the Pontiac LeMans. This change was not taken to very well by customers, so Pontiac was forced to reintroduce a full-sized vehicle. They brought over the Canadian-built Pontiac Parisienne, which was basically a re-styled Chevy Caprile that was powered by a Chevrolet V6 or V8 engine. Once again, Bonneville was placed one notch below the top of the line.
Just like the previous time, downsizing became the salvation that the Bonneville needed. The Parisienne was discontinued in 1987, and the Bonneville was redesigned completely as a front-wheel drive vehicle and once again rejoined in pre-1982 platmform buddies, the Buick LeSabre and the Oldsmobile Eighty-Eight. It again regained its status as the senior Pontiac and the SE Bonneville was placed on Car and Driver magazine's Ten Best list for that year.
The decision was made by Pontiac to change the Bonneville from rear wheel drive with a V8 engine to a more economical front wheel drive 3.8 V6 vehicle in 1987. The V6 that was installed was a 3.8L V6 with the RPO code of LG3. A dive in the performance market soon followed, as this engine only produced around 150 hp, though it had a kick of 210 ft-lbs of torque power.
The following model that was introduced in 1989, the Bonneville LE may have been Pontiac's attempt to add a bit more of pep and pizazz to the Bonneville line. This new model moved up to 15 hp and 10 ft-lbs of torque, and this engine has the RPO code of LN3. The Bonneville was once again redesigned in 1991, though it did remain as an H-body.
A total redesign was done in 1992 to the exterior of the Bonneville, though the interior experienced very few changes. The LE trim was also taken off the lineup. Available trims for 1992 were SE, SSE, and SSEi, and airbags now came as standard features in Bonnevilles. Nearly 100,000 Bonneville models were sold in 1992.
Things once again changed in 1993, though the exterior remained the same, the interior did go through a slight update. A sport Luxury Edition was made available for '93, which was basically a base SE, with an SSE exterior, an all of the same available options as an SE. Much remained unchanged for the 1994 model. Much of the vehicle has remained the same throughout the next few years, making way for a total redesign for the 2002 model year.
The Bonneville regained a V8 option on the GXP trim for 2004, which has been a first since 1986. On February 8, 2005, GM announced that the Bonneville would be dropped from Pontiac's lineup for 2006. The high-end Pontiac Grand Prix GXP trim replaced the Bonneville.
For many years, the vehicle fondly called the 'Bonne', the Pontiac Bonneville has showcased a mix of luxury, performance with the aid of a supercharged 3.8 liter engine.By Jessica Donaldson
