Chevrolet Cobalt

Chevrolet Cobalt LS coupe

The Chevrolet Cobalt is a compact car introduced by Chevrolet in 2004 for the 2005 model year. The Cobalt replaced the Cavalier and the Prizm as Chevrolet's compact car.

It is available as both a coupe and sedan and is based upon the GM Delta platform also shared with the Chevrolet HHR, Pontiac G5, Astra (Opel, Vauxhall, Holden, and Saturn marques), and the Opel Zafira (a seven seat MPV). Also available is a high performance, Super Sport variant. All Cobalts are currently manufactured at GM's Lordstown Assembly plant in Lordstown, Ohio. The United States Environmental Protection Agency‎ classifies the Cobalt as a subcompact car.

The front suspension is independent with MacPherson struts, while a semi-independent torsion bar is used in the rear. The wheelbase is 103.3 in (2,624 mm), longer than its competitors, and the width is 68.4 in (1,737 mm) . Weight is average in-class, at 2,681 lb (1,216 kg) for the coupe and 2,747 lb (1,246 kg) for the sedan. The Cobalt uses an electric power steering system developed by Koyo Seiko, rather than a conventional hydraulic system. For 2009, the United States Environmental Protection Agency‎ fuel economy has increased to 24 mpg-US (9.8 L/100 km; 29 mpg-imp) city/34 mpg-US (6.9 L/100 km; 41 mpg-imp) highway with automatic transmission, and26 mpg-US (9.0 L/100 km; 31 mpg-imp) city/37 mpg-US (6.4 L/100 km; 44 mpg-imp) highway with manual transmission. The engine output has increased to 155 hp (116 kW).

The 2008 Cobalt is available with the SS performance package, which includes a 260-hp 2.0L straight-4 turbocharged engine with variable valve timing, rated at 22 mpg-US (11 L/100 km; 26 mpg-imp) city, 30 mpg-US (7.8 L/100 km; 36 mpg-imp) hwy, with its 5-speed manual transmission. It can achieve 0-60 mph in 5.7 seconds.

The 2008 Cobalt line also offers a Sport model, with a naturally aspirated 171 hp (128 kW) high-output engine, rated at 22 mpg-US (11 L/100 km; 26 mpg-imp) city/32 mpg-US (7.4 L/100 km; 38 mpg-imp) hwy (manual transmission), and 22 mpg-US (11 L/100 km; 26 mpg-imp) city/31 mpg-US (7.6 L/100 km; 37 mpg-imp) hwy (automatic transmission). Previous to 2008 this power combination was offered as one of the SS package combinations.

According to the Insurance Institute for Highway Safety (IIHS) the Cobalt receives an overall top score of Good for front collisions. However, it receives a Poor overall score for side impacts without side curtain airbags, and an Acceptable overall score with side curtain airbags. In 2008 side curtain airbags became standard but the Cobalt's structure remains the same and consequently in structure/safety category of the IIHS's side impact test the Cobalt receives a Marginal score.

Before 2009 the Cobalt only offered stability control as an option on Sport models. Side airbags are limited to head-curtain type, torso type side airbags are unavailable. According to the IIHS's injury measurements taken from the side impact test the driver's torso is given a Marginal score.

In early 2007, 98,000 Cobalt coupes were recalled after it was discovered they did not meet federal safety requirements because of a lack of adequate padding in a specific area of the vehicle's trim, resulting in an unacceptable vulnerability to head injuries.

Chevrolet Cobalt SS

Supercharged coupe with standard high profile decklid spoiler

The Chevrolet Cobalt SS is a sport compact high performance version of the Chevrolet Cobalt, featuring three inline-4 Ecotec engines, built on the General Motors Delta platform. The car debuted with a 205 hp (153 kW) supercharged 2.0 L engine in late 2004, the only transmission option being the F35 manual of GM Europe. The engine had been first introduced one model year prior on the Saturn Ion Red Line. For 2006, a naturally-aspirated Cobalt SS with both automatic and manual transmission options was one of three Delta cars to carry GM's new 2.4 L,171 hp (128 kW) engine. A second 2.0 L engine exclusively mated to the F35, with power upped to 260 hp (194 kW) by way of a turbocharger, revived the Cobalt SS in the second quarter of 2008 after a brief hiatus (See timeline).

The powertrain of the Cobalt SS has received generally positive reviews, especially the turbocharged version, but the car has been criticized for poor interior quality and exterior styling that is too reminiscent of its predecessor, the Chevrolet Cavalier. The Super Sport moniker had not been used on the Cavalier, a compact built on the widely used and now obsolete J platform. Though the car was produced until 2005, it saw its most powerful trim, the Z24 featuring a 2.4 L 150 hp (112 kW) engine, cancelled in 2002 as GM prepared to phase out the platform. Chevrolet will end production of the Cobalt within a few years and replace it with the European-developed Cruze after producing the two simultaneously for the North American market, but a high performance version to directly replace the Cobalt SS has not yet been announced, nor any possible powertrains.

The first Cobalt SS was launched in 2004 as a 2005 model with a new powertrain that had debuted one year earlier on the Saturn ION Red Line. It was available as a Supercharged coupe only. The naturally-aspirated 2.4 L LE5 engine was the next SS to launch in late 2005 as a 2006 model. However in late 2007, at the same time the announcement cancelling the SS Supercharged was made, GM also announced that the 2.4 L would be renamed "Cobalt Sport", but would be identical to the former SS vehicle. Like the supercharged car, the 2.0 L LNF turbocharged Cobalt launched in the second quarter of 2008 was initially available only as a coupe until a sedan option was offered for the 2009 model year. For its run from 2006-2008, the 2.4 L Cobalt was available as both a coupe and sedan.

All three models of the Cobalt SS feature four wheel, anti-lock disc brakes. Compared to the base Cobalt, the SS has lower front and rear fascias for a more aggressive look with integrated foglamps, side rocker moldings, interior accents, and a chrome exhaust tip. Exclusive to the 2.0 L Cobalt are a titanium-faced sport analogue cluster with a 160 mph (260 km/h) speedometer, an A-pillar mounted boost gauge, reclining front bucket seats with two-tone leather-appointed seating surfaces, vertical adjusting head restraints and driver-side lumbar and height adjusters, and a sport-tuned FE5 suspension with a 24 mm front stabilizer bar and 22 mm rear stabilizer bar.

Available as a coupe only, the SS Supercharged featured the 2.0 L LSJ Ecotec engine with an Eaton M62 Roots type supercharger and air-to-liquid intercooler. The engine makes 205 hp (153 kW) at 5600 rpm and 200 lb·ft (271 N·m) at 4400 rpm. 18-inch broad-spoke wheels with P215/45R18 all-season Pirelli tires are standard. Optional for the LSJ was a performance package coded G85 that added Recaro bucket seats and a limited slip differential (LSD). The G85 option continues in the LNF Cobalt, but adds only the LSD. The car has become notable for a high profile spoiler that was standard in 2005, but optional from 2007 when a lower profile spoiler used on all other Cobalt coupes became an option.

GM offers dealer-installed performance upgrade packages called "stage kits" that are covered by factory warranty. The Stage 1 kit consists of new fuel injectors and a reprogram of the ECU, and yields up to a 30 hp (22 kW) improvement. The Stage 2 kit consists of new fuel injectors and the same reprogram with a smaller serpentine belt and pulley for the supercharger, producing a 47 hp (35 kW) improvement and 30 lb·ft (41 N·m) of torque. Both stage 1 and 2 kits increase the engine redline to 7,000 rpm. The Stage 3 kit consists of a smaller, 76 mm (3 in) supercharger pulley, a 2-pass intercooler end plate and a customizable replacement ECU. The Stage 3 ECU allows for the use of a 50-shot of nitrous, 100 octane fuel and an adjustable redline from 6,750 to 8,000 rpm. Stage 3 produces 248 hp (185 kW) using 93 octane fuel, up to 260 hp (194 kW) using 100 octane fuel, and much higher power with nitrous. Stage 3 is for track use only, and to emphasize this, air conditioning is disabled with the Stage 3 ECU.

A problem frequently encountered with the car, due to a combination of its high torque, front drive, and short first gear is wheel hop, wheelspin and a general lack of traction. The GM Performance Division later tried to rectify these problems in the turbocharged car by providing wider, stickier tires and stronger axles.

The LSJ engine did not meet emissions requirements for the 2008 model year, and General Motors' contract with Eaton had expired. The non-supercharged 2.4 L Cobalt SS also lost its Super Sport designation for the 2008 model year and was renamed "Sport". However, in fall 2007, a more powerful Cobalt SS was announced for the second quarter of 2008. The car would be equipped with the 2.0 L, turbocharged, direct injected, VVT, LNF Ecotec engine, making 260 hp (194 kW) at 5300 rpm and 260 lb·ft (353 N·m) at 2000 rpm, and remain mated to the F35 5-speed manual transmission. The engine had been introduced in a rear wheel drive application for the 2007 GM Kappa platform, which includes the Saturn Sky, Pontiac Solstice, and Opel GT.

Also new for the 2008 SS were SS-embroidered sport seats with suede-like UltraLux inserts, several new exterior colors, and wider 18-inch (460 mm) forged, split-spoke wheels with P225/40R18 Continental AG tires, reminiscent of those offered for the Chevrolet Corvette C6. The car's electronics are also new, and along with greater assist in poor traction conditions, add a "no-lift-shift" feature which allows the driver to maintain turbocharger boost during upshifts. During a no-lift-shift, the driver shifts normally by depressing the clutch, but the accelerator pedal is held wide open. Also new is "launch control", which feathers the throttle at roughly 4800 rpm until engagement of the clutch, allowing more consistent launches in competitive situations. To use the feature the driver presses twice on the traction control button which first turns off traction control, and then notifies the driver through the Driver's Information Center that the launch control of Competitive Mode has been enabled. However, turbocharged Cobalt owners have found that better times can be achieved while racing when the car is manually launched. These features help propel the car from 0 to 60 mph (97 km/h) in a class-leading 5.5 seconds, and a quarter mile time of 13.9 seconds at 102.5 mph (165.0 km/h).

New for 2009 is the aforementioned four-door sedan option, as well as an optional "reconfigurable performance display" (RPD) for the coupe only. The $295 option replaces the boost gauge in the A-pillar, and allows the driver manipulation of traction control, stability control, and the engagement of Competition Mode, as well as well as information regarding the car's engine torque and horsepower, g-force, boost, wideband air fuel ratio, barometric pressure, temperature, and battery voltage.

Chevrolet introduced a naturally-aspirated Cobalt SS in the fall of 2005, as a 2006 model available as both a coupe and sedan. It featured the 2.4 L LE5 Ecotec engine with variable valve timing, making 171 hp (128 kW) at 5,600 rpm and 163 lb·ft (221 N·m) at 5000 rpm, later upped to 167 lb·ft (226 N·m) at 4500 rpm. The LE5 engine was new for 2006 and was introduced on both the FWD Delta platform and RWD Kappa platform. For the 2006 and 2007 model years the car was called SS, or "1SS", but was replaced with the moniker "Cobalt Sport" for 2008 with the anticipated introduction of the turbocharged super sport car later on in the model year. For the first time, a 4-speed automatic transmission was offered, the 4T45. The 5-speed manual is also different from the Cobalt SS Supercharged, it is the Getrag F23 transmission with different ratios that is offered for the 2.2 L L61 engine in the Cobalt LS and LT.

Other changes over the supercharged car are notable but not drastic; 17-inch broad-spoke wheels with narrower P205/50R17 all-season Pirelli tires are standard, as is the low profile spoiler. 2.4 L and 2.2 L Sport Package Cobalts have a 140 mph (220 km/h) speedometer) with optional white face gauges. The car rides on the FE3 suspension, superior and more sport-tuned to that of base Cobalts but less refined than the FE5 on the supercharged and turbocharged cars. Brakes are identical to the SS Supercharged. The front and rear bumpers are the same, but the front lacks a lip accessory and the bottom of the rear fascia is slightly different. With the negligible exception of exterior styling and some interior trims, the vehicle is identical to the Pontiac G5 GT.

Reviews of the supercharged Cobalt SS have been generally positive. While critics had harsh words for the Cavalier, the supercharged Cobalt was seen as a superior vehicle and a worthy entry into the tuner market in 2004. However, the general fit and finish was poor, and power levels were not up to par with other competitors. Journalist Thom Blackett said, "When compared with more contemporary cars including the Dodge Neon SRT-4 and the Subaru WRX, that SS badge seems to lose some of its luster." The F35 transmission has also been deemed inferior to that in the newest of generation of Honda's Civic Si. Critics also disliked the heavy wheels which negatively affected handling, as well as the spoiler which obstructed rearward visibility. Speaking of the high profile aero wing, automotive journalist Alexandra Straub said, "the deck-lid spoiler was directly in my line-of-sight when looking out of the rearview mirror. It's almost like it cut everything in half." Some Cobalt SS owners have traded spoilers with lower trim owners to obtain a less aggressive look, or traded the entire trunklid with Cobalt LS owners, for whom a rear spoiler is merely optional. The naturally-aspirated Cobalt SS has been seen as an improvement over the base models with its slightly more potent 2.4 L engine, but notably inferior to the supercharged car.

The 2008 turbocharged Cobalt SS has received rave reviews. John Neff of Autoblog said, "The GM Performance Division completely reworked the Cobalt SS for 2008, swapping in a more powerful turbocharged engine, upgrading the rest of the mechanicals, and tweaking the entire package on the world's most demanding race tracks, including the famed Nürburgring in Germany. The result is – and we're not kidding here – the most impressive performance car to wear a bow-tie badge on sale today." Journalists were impressed with the performance of the car in relation to the price; Neff added that the "2009 Cobalt SS Turbo is freakishly good at going fast and the best bang-for-the-buck value below $30,000." Ron Kiino of Motor Trend said, "at only $22,995, the SS could stand for Super Steal." The MSRP was raised to $24,095 for the 2009 model year.

Chevrolet Cavalier

2000-2002 Chevrolet Cavalier sedan

The Chevrolet Cavalier was a compact automobile produced from 1982 to 2005 by General Motors. Built on the company's J platform, the Cavalier was one of the best-selling cars in the United States throughout its life.

The Cavalier replaced the Monza, which was available as a 2-door coupe, a 3-door hatchback and a 3-door wagon (using the same body as the discontinued Vega wagon, the model it replaced). The inexpensive Chevette was retained even as sales declined, and was formally replaced by even smaller captive imports. Both previous platforms had conventional rear-drive layouts while the new design could compete on the same level with more efficient front wheel drive offerings, such as the Dodge Omni and Honda Civic. Ford and Chrysler also introduced new front drive compacts. The largely successful mission of capturing the bulk of domestic compact sales would fall on the Cavalier's 2-door coupe, 4-door sedan and 4-door station wagon, the relatively short-lived 3-door hatchback (which replaced the Monza 2+2 Sport 4-door hatchback) and, in later years, a 2-door convertible. The small Cavalier even helped fill in lagging sales of the compact Citation (a Nova replacement).

The Cavalier first went on sale in early 1981 as a 1982 model with front-wheel-drive, a choice of two four-cylinder pushrod engines, and coupe, sedan, hatchback, and station wagon body styles.

1983 Cavaliers offered electronic fuel injection, and a V6 engine became available in 1985, uncommon for a compact car. 1985 also brought minor styling changes.

The Cavalier was largely identical to the Pontiac Sunbird. Before the Pontiac brand was officially introduced in Mexico in 1992, Cavaliers sold there featured Sunbird body panels, as opposed to US-spec Cavalier panels. From 1993 on, the sibling marques were both offered, as in the United States.

1988 Cavaliers were redesigned with fresh styling and modified engines. The hatchback disappeared from the line, but the other bodystyles continued. The exterior and interior were freshened in 1991.

The Cavalier was redesigned for 1995 with expanded dimensions and styling that was a departure from the two boxier previous generations. The wagon was discontinued, but the coupe, sedan, and convertible body styles returned. This model is very similar to the Pontiac Sunfire, being the only difference the taillights and the Sunfire's sportier fender.

The Cavalier was facelifted in 2000 and in 2003. The convertible disappeared after 2000.

The Cavalier was replaced by the Chevrolet Cobalt in 2005.

The third-generation Cavalier earned several low scores in crash tests by the Insurance Institute for Highway Safety and National Highway Traffic Safety Administration. Also, IIHS fatality risks statistics rated the Cavalier among the "Highest rates of driver deaths," with 150 (4 door) to 171 (2 door) driver deaths per millon registered vehicle deaths. Average for the Cavalier class (small) was 103(4 door) to 134(2 door) driver deaths per millon registered vehicle deaths.

The IIHS gave the 1995-2005 Cavalier a Poor overall score in their frontal offset collision test.

Most Cavaliers were built at Lordstown Assembly, although they have also been produced in South Gate, California (1982 model year only), Lansing Car Assembly (1996-1998 coupes), Lansing Craft Centre (1996-2000 convertibles), Janesville Assembly, Ramos Arizpe, and Leeds Assembly.

As part of a wider effort to avoid additional restrictions on exports to the US, the third generation model was briefly sold in Japan by Toyota under an agreement with GM, badged as the Toyota Cavalier. Aside from the fact that it was right hand drive, the Toyota Cavalier also featured a leather-wrapped shift knob and steering wheel, wider front fenders, amber turn signals for Japanese regulations, power folding rear mirrors, side turn signal repeater lights on the front fenders, and carpeting on the inside of the trunk lid. Interior seats were often flecked with color, and the rear seat had a fold-down armrest. The Toyota Cavalier was entirely produced by GM in the USA and sold from 1995 - 2000. 1996-2000 Toyota Cavaliers came equipped with the 2.4L LD9 engine, while the 1995 used the 2.3 liter quad 4.

While all Chevrolet-badged Cavaliers received a facelift for 2000, the Toyota did not and used the same basic design for the 2000s as it did for the 1995-1999 models. The only exception to this is the colors available, the interior trim colors and the tail-lights.

A fair number of these vehicles are re-exported as Japanese used cars, most notably to New Zealand. Production of the Toyota Cavalier ceased in June 2000.

TRD made a body kit and rear wing for the Cavalier, available exclusively in Japan.
