The Chevrolet Cobalt is a compact car introduced by Chevrolet in 2004 for the 2005 model year. The Cobalt replaced the Cavalier 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 EPA classifies the Cobalt as a subcompact car.[2]
Starting in 2009, Chevrolet will launch the Cobalt's global successor the Chevrolet Cruze (based on the new Delta II platform) in Europe with launches in other markets (including the US) to proceed in 2010. The Cruze will be built in multiple locations around the world including the Lordstown Assembly, at which the Cruze will briefly be built alongside the Cobalt until the latter is completly phased out.[3] "The Cruze will build on the already successful Chevrolet Cobalt, Cobalt XFE and Cobalt SS, all of which are nearly sold out in dealer showrooms," said GMNA vice president of Chevrolet Ed Peper. “Our dealers are asking for many more Cobalts than we can build."[4]
Specifications
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. (1216-1246 kg), and best EPA fuel economy is 25 mpg‑US (9.4 L/100 km; 30 mpg‑imp) city/36 mpg‑US (6.5 L/100 km; 43 mpg‑imp) highway. The car is notable for its use of an electric power steering system developed by Koyo Seiko, rather than a conventional hydraulic system. For 2009, the EPA fuel economy has increased (as well as power) to 24 mpg‑US (9.8 L/100 km; 29 mpg‑imp)/34 mpg‑US (6.9 L/100 km; 41 mpg‑imp) (AT) and 26 mpg‑US (9.0 L/100 km; 31 mpg‑imp)/37 mpg‑US (6.4 L/100 km; 44 mpg‑imp) (MT) with 155 hp (116 kW) respectively.
Year-to-year changes
- 2006: A non-supercharged Cobalt SS was added to the lineup. This car is equipped with a 2.4L naturally-aspirated Ecotec inline-4. The LS became the base model while the LT was marketed as a mid-range package; the top level trim was now the LTZ. In addition, as with most other GM vehicles that year, GM's Mark of Excellence symbol was added to both front fenders near the doors.
- 2007: Both engines were retuned for more power while retaining the same fuel economy. The 2.2 L Ecotec is now rated at 148 hp (110 kW) with the 2.4 L Ecotec rated at 173 hp (129 kW). Other changes include a new console, new steering wheel and new radio head unit that features an audio input jack. In addition, all models except the LS and LT1 now use a 5x110 wheel bolt pattern. The LS and LT1 retained the standard 4x100. In addition, the 2007 model year marked the introduction of a new 32-bit computer that replaced the 16-bit unit from 2006.
- 2008: The 2.4L naturally aspirated, high-output SS coupe and SS sedan were renamed to just "Sport Coupe" and "Sport Sedan" respectively. The new Cobalt SS features a 260 hp (194 kW) turbocharged engine, replacing the Supercharged engine which was offered from 2005-2007. At mid-year, the fuel economy was increased to 25 city, 36 highway MPG on the LS and 1LT, coupe and sedan models with manual transmission; now labeled with XFE badging (X-tra Fuel Economy).[5] XM Radio, side-impact air bags for improved safety, and MP3 player are now standard instead of optional. StabiliTrak stability control system is introduced. Other changes include the adding and removal of several exterior and interior colors. The new SS (turbocharged) coupe launched near the end of May 2008, as it was a facelift from the 2005-2007 version. A sedan version is available for 2009.
- 2009: The 2.4L naturally aspirated "Sport Coupe and "Sport Sedan" models have both been deleted, along with the 2.2L L61 engine. Both are replaced by the 2.2L LAP engine thus providing better fuel economy and more power. Three exterior colors have been changed, and the neutral interior color deleted. Bluetooth capabilities have been added, as well as the option for a reconfigurable performance display.[6] The RPD, only available on the SS coupe, can read out various engine output data and alter performance settings.
Performance
The 2008 Cobalt is available with the SS performance package[7], which includes a 260-hp 2.0L I-4 turbocharged engine with variable valve timing, rated at MPG 22 city, 30 hwy, with its 5-speed manual transmission. It can achieve 0-60mph in 5.7 seconds. [8]
The 2008 Cobalt line also offers a Sport model, with a naturally aspirated 171 hp (128 kW) high-output engine, rated at 22 city/32 hwy MPG-US (manual transmission), and 22 city/31 hwy MPG-US (automatic transmission). Previous to 2008 this power combination was offered as one of the SS package combination's.
Safety
According to the IIHS the Cobalt receives a top score of "Good" for front collisions. [9] However, it receives a poor overall score for side impacts without side curtain airbags,[10] and an average overall score with side curtain airbags.[11]
The Cobalt only offers stability control as an option on Sport models. [12] Side airbags are limited to head-curtain type, thorax type side airbags are unavailable.[12]
Recalls
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.[13]
