    Chevrolet Cobalt SS 2004-2010

    2005 CHEVROLET COBALT: AN ALL-NEW PREMIUM SMALL CAR

    With the Cobalt and all-new 2004 Aveo, Chevrolet is well positioned in the entry level and premium small car segments.

    Cobalt offers a diverse selection of expressive body styles, refined interiors, race-inspired Ecotec four-cylinder engines, smooth-shifting transmissions, precision-tuned suspensions and dynamic wheels. The dynamic driving experience has its foundation in GMís solid Delta architecture.

    Models
    The Cobalt family includes two models, sedan and coupe, and a total of eight trim levels. The sedan model features base, LS, LT and SS trims, while coupe models are available in base, LS, SS and SS Supercharged trims - more details on the Cobalt SS Supercharged will be announced later. Each distinct model includes a specific interior, powertrain, suspension and wheels, as well as a long list of standard and available features.

    Pricing will be announced in late summer 2004.

    Expressive Chevrolet design
    The Cobalt family continues Chevroletís refined and expressive design character. The sedan offers sophisticated appearance coupled with a higher seating position for a more commanding view of the road. For the coupe, Chevrolet builds on the identity of Americaís most aspirational sport coupe, the Corvette. Leveraging the style of the sedan from the A-pillar forward, the Cobalt coupe reveals an elegantly tapered reverse C-pillar leading the eye to Chevroletís signature four round taillamps.

    Other Chevrolet styling cues include a bold, dual-port grille and gold bowtie at its center. All Cobalt models have precise metal fits, too. For example, there are 3.5-mm tolerances between the fenders and doors, as well as 3-mm tolerances on the hood and decklid.

    Great attention was also given to the use of tailored rubber moldings for a clean appearance. All models feature body-color moldings and door handles, as well as jewel-like headlamps and taillamps. Several wheel options also are offered, including standard 15-inch wheels and available 16-inch, 17-inch, and 18-inch wheels, all with unique designs.

    The Cobalt family features 10 contemporary exterior colors.

    The interiors of the Cobalt models reflect the same attention to detail as with the exterior designs. The high level of refinement is apparent in the quality of materials, appointments and styling cues used throughout the cabin. The execution of the gauges, knobs and buttons is simple and easy to use, yet elegant.

    Comfort is emphasized in all of the Cobalt models, with seats designed to reflect the various performance levels. The seats hold occupants firmly in position to deliver the right balance of comfort and security while cornering. They also are bolstered in the seatback and cushion without being intrusive, providing comfort for both short and long drives.

    Standard features

    Cobalt offers a long list of standard features including air conditioning, electric rear defogger, CD player and driver information center. Available features include heated leather seats, power sunroof, XM Satellite Radio, MP3 playback and OnStar. In addition, Cobalt features plenty of interior flexibility, including easy access to the rear seat, 60/40 folding rear seats, interior access to the trunk area, as well as ample, versatile storage.

    Dynamic driving experience
    With a strong structural foundation and wide array of engines, transmissions and suspensions, Cobalt delivers a dynamic driving experience regardless of model and trim level. In addition, safety and interior noise were significantly addressed throughout the development, delivering a safe and pleasing interior experience.

    Cobalt was created on a strong foundation - GMís Delta architecture. The rigid lower-dominant body structure is engineered as a single unit for mass efficiency and stiffness. The underbody uses high-strength steel as welded members in strategic locations for maximum strength, structural integrity, mass optimization and crashworthiness.

    Noise reduction
    One-piece stamped tailor welded blanks are used for the inner and outer frame for added rigidity. In the instrument panel mounting area, a sound-deadening plenum is formed from a plastic layer sandwiched by thin steel sheets.

    The Cobaltís stiff underbody also supports a quiet ride, producing nearly 27 Hz in bending frequency. The rigid cockpit structure provides additional noise reduction, as well as providing load-carrying capability for crash protection. All other cabin entry points for noise have been addressed with seals, carpeting or other sound-deadening materials. Engine and decklid covers were extensively engineered to reduce noise.

    The powertrain is supported by a torque-axis mounting arrangement that allows the suspension to operate at maximum efficiency while minimizing engine noise and vibration. Additionally, the doors, trunk and hood have all been engineered to have a solid closing sound.

    Ride and handling
    Cobaltís advanced chassis systems are tuned to deliver ride and handling characteristics to fit the diverse requirements of a broad customer base. Electric power steering also is tuned to match the performance levels of the various tire and suspension packages. The tight turning radius is 34.8 feet (10.6 meters) curb to curb. Cobalt features a strut-type front suspension, semi-independent torsion beam rear suspension, and front and rear stabilizer bars for more exact body roll control.

    Brakes and traction control
    Vented front disc brakes with single-piston calipers and composite drum rear brakes are standard on the base models. Four channel anti-lock brakes (ABS) are standard on LS, LT and SS models. Four-wheel disc brakes with ABS are standard on SS models. Cobalt also features an enhanced electronic traction control system.

    Safety
    The rigid body structure that enables Cobaltís 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 pre-tensioners, rear center shoulder belts and the LATCH child seat retention system are also standard equipment.

    Powerful powertrains
    Cobalt offers three race-inspired Ecotec four-cylinder engines, one proven automatic transmission and two manual transmissions. The Ecotec family includes a standard 2.2-liter engine in the base, LS, and LT models; a new 2.4-liter engine standard in the SS coupe and sedan; and a 2.0-liter supercharged engine standard in the SS Supercharged coupe.

    The Ecotec 2.2-liter engine delivers an estimated 140 horsepower and 150 lb.-ft. of torque. The combination of increased displacement and variable valve timing technology enables the Ecotec 2.4-liter to achieve one of the highest torque ratings - an estimated 170 lb.-ft. - for a 2.4-liter naturally aspirated four-cylinder in the United States. The 2.4-literís 170 horsepower at 6000 rpm also is one of the highest specific-power outputs for any non-boosted four-cylinder of any size sold in the U.S., according to Wardís 2003 market data.

    The 2.2-liter and 2.4-liter dual overhead camshaft (DOHC) engines feature aluminum block and cylinder heads, counter rotating balance shafts, roller finger follower valve lifters, chain driven camshafts, electronic throttle control, coil-on-plug ignition, GM Oil Life System and extended life spark plugs and coolant.

    With the new 2.4-liter engine, variable valve timing (VVT) is introduced to the Ecotec family. The new VVT system uses electronically controlled hydraulic camshaft phasers to alter the relationship of the intake and exhaust camshafts as much as 50 degrees relative to the crankshaft for improved performance and efficiency.

    The Ecotec 2.2-liter is the foundation for GMís front-wheel-drive drag racing efforts. The race-prepared Ecotec engine, which produces more than 1,000 horsepower, powers GM Racingís Chevrolet Cavalier in the NHRA front-wheel-drive Sport Compact class and has been a proven winner throughout 2003.

    Mated to the Ecotec 2.2-liter engine in the Cobalt is a standard Getrag five-speed manual and available Hydra-Matic 4T45-E electronically controlled four-speed automatic transmission. The compact and efficient five-speed manual features five synchronized forward gears and a synchronized reverse gear. The 4T45-E is engineered to deliver transparent shifts in a quiet and durable package. With the Cobalt SS Supercharged modelís 2.0-liter supercharged engine, a manual transmission tailored to its unique power bands is included.

    I caught an ad in the local paper for $94/mo for one of these babies... I've been researching all night. Does anybody know about actual VALUE of these things? Are they solid? Are they good for long trips? Are they comfortable?


    edit:
    The 2.2L ecotec dohc---how good is this engine? I've been looking for reviews and have been completely unable to find anything resembling an actual review.
    But the manual transmission! Wow! That sounds very ncie.

    Seeing as they've just been released, a lot of 'long term' isn't known. The Ecotec is supposed to be a bulletproof motor though.

    Bulletproof but rough as anything. The only nicer version of it I've ever driven was in a new Saab 93, and still it was nothing to call home about.
