Chevrolet Improves 2012 Cruze’s Fuel Economy by 2MPG and Adds New Standard Features

General Motors is releasing a model year update for its Cruze compact sedan. There are no styling changes as the company focused its attention on improving the car’s fuel economy and equipment features.

Thanks to a lower axle ratio for the 2012 models equipped with a six speed automatic transmission, the standard Cruze with the 138HP 1.4-liter turbocharged engine returns 38 mpg compared with 36 mpg for the current model, while the Cruze Eco with the same powetrain setup delivers 39 mpg instead of 37 mpg.

The Cruze Eco with the standard six-speed manual gearbox remains unchanged for 2012 returning 42 mpg on the highway.

Other than that, GM has enhanced the standard features across the range with the addition of Bluetooth phone connectivity, USB port, steering wheel-mounted audio controls, cruise control, leather-wrapped steering wheel and a leather-wrapped shift knob. These features were part of the $525 Connectivity Plus Cruise option package on 2011 models. According to the Detroit automaker, the option was ordered by 90 percent of American customers.

“Chevrolet is committed to responding to what customers want and making it easier for them,” said Rick Scheidt, vice president of Chevrolet marketing. “Adding these previously optional features streamlines the ordering process and answers the call of what our customers told us should be standard.”

Additional standard equipment on the 2012 Cruze includes:

• Remote keyless entry
• Air conditioning
• Audio system with AM/FM/CD and MP3 playback
• SiriusXM Satellite Radio with three-month trial service
• Driver information center with average and instant fuel economy feedback, tire pressure readout, oil life remaining and more
• Rear defogger

Cars Show 2009 Chevrolet Corvette ZR1

Chevrolet officially announced the 2009 Chevrolet Corvette ZR1 - an American supercar that brings the technology and engineering refinement of carbon-fiber, ceramics and electronics together in a distinctive design.

"Chevrolet's goal with the new Chevrolet Corvette ZR1 is to show what an American supercar can deliver, at a price that trumps exotics that cost two, three or four times as much - and does so with exceptional driveability," said Ed Peper, Chevrolet general manager.

The Chevrolet Corvette ZR1's basic stats:

* All-new LS9 supercharged 6.2L V-8 targeted at producing at least 100 horsepower per liter, or 620 horsepower (462 kW), and approximately 595 lb.-ft. of torque (823 Nm)
* Six-speed, close-ratio, race-hardened manual transmission
* New, high-capacity dual-disc clutch
* Higher-capacity and specific-diameter axle half-shafts; enhanced torque tube
* Specific suspension tuning provides more than 1g cornering grip
* Twenty-spoke 19-inch front and 20-inch rear wheels
* Michelin Pilot Sport 2 tires - P285/30ZR19 in front and P335/25ZR20 in the rear - developed specifically for the Chevrolet Corvette ZR1
* Standard carbon-ceramic, drilled disc brake rotors - 15.5-inch-diameter (394-mm) in the front and 15-inch-diameter (380-mm) in the rear

The specialized components of the new Chevrolet Corvette ZR1 work harmoniously to deliver the most powerful and fastest automobile ever produced by General Motors. Performance estimates will be announced closer to vehicle's summer 2008 launch.

"Preliminary testing shows the Chevrolet Corvette ZR1 builds on the highly respected Chevrolet Corvette Z06 in every performance category, from acceleration and braking, to cornering grip and top speed," said Peper. "It all boils down to the power-to-weight ratio and the Chevrolet Corvette ZR1's is exceptional - better than the Porsche 911 GT2, the Ferrari 599 and even the Lamborghini Murcielago LP640. In fact, the Chevrolet Corvette ZR1 is expected to be the first production Corvette to achieve a top speed of at least 200 mph."

Supercharged LS9 engine

The new LS9 6.2L small-block engine is the power plant the supports the Chevrolet Corvette ZR1's performance capability. The enabler of the LS9's performance and refinement is a large, positive-displacement Roots-type supercharger with a new, four-lobe rotor design. It is augmented with an integrated charge cooling system that reduces inlet air temperature for maximum performance.

A sixth-generation supercharger developed by Eaton helps the LS9 make big power and torque at lower rpm and carries it in a wide arc to 6,600 rpm, as it pushes enough air to help the engine maintain power through the upper levels of the rpm band - the area where supercharged performance tends to diminish. Heavy-duty and lightweight reciprocating components enable the engine's confident high-rpm performance.

The LS9 is hand-assembled at GM's Performance Build Center, in Wixom, Mich., and incorporates specialty processes typically seen in racing engines to produce a highly refined and precise product. For example, cast iron cylinder liners are inserted in the aluminum block and are finish-bored and honed with a deck plate installed. The deck plate simulates the pressure and minute dimensional variances applied to the block when the cylinder heads are installed, ensuring a higher degree of accuracy that promotes maximum cylinder head sealing, piston ring fit and overall engine performance.

Transmission and axle

The LS9 engine is backed by a new, stronger six-speed manual transmission and a twin-disc clutch that provide exceptional clamping power, while maintaining an easy clutch effort. Chevrolet Corvette ZR1-specific gearing in the transmission provides a steep first-gear ratio that helps launch the car, and top speed is achieved in sixth gear - a change from the fifth-gear top-speed run-outs in the manual-transmission Corvette and Corvette Z06.

As the term implies, the twin-disc clutch system employs a pair of discs, which spreads out the engine's torque load over a wider area. This enables tremendous clamping power when the clutch is engaged, while also helping to dissipate heat better and extend the life of the clutch.

The twin-disc clutch system also contributes to the Chevrolet Corvette ZR1's exceptional driving quality, with smooth and easy shifting. The twin-disc system's design enables a 25-percent reduction in inertia, thanks to smaller, 260-mm plates, corresponding to a pedal effort that is similar to the Corvette Z06's 290-mm single-disc system.

The rear axle also is stronger in the Chevrolet Corvette ZR1 and features asymmetrical axle-shaft diameters that were developed after careful testing to provide optimal torque management. The axles are also mounted on a more horizontal plane that correlates with the wider width of the rear wheels and tires.

Ride and handling

The Chevrolet Corvette ZR1 is built on the same aluminum-intensive chassis as the Corvette Z06 and features similar independent SLA front and rear suspensions, with aluminum upper and lower control arms. Where the Chevrolet Corvette ZR1 differs is the suspension tuning, which was optimized for the car's steamroller-wide front and rear tires.

Magnetic Selective Ride Control is standard and tuned specifically for the Chevrolet Corvette ZR1. The system's ability to deliver a compliant ride with nearly instantaneous damping adjustments enabled engineers to develop a surprisingly supple ride quality in a supercar that still delivers cornering grip of more than 1g.

From a high-performance perspective, Magnetic Selective Ride Control helps the rear axle remain planted during launch for smooth, hop-free acceleration. It also helps suppress axle movement when cornering on broken or uneven pavement.

Brakes, wheels and tires

Commensurate with the Chevrolet Corvette ZR1's engine output is the braking system, which is headlined by carbon-ceramic brake rotors. Found on only a few exotics and more expensive supercars, carbon-ceramic brake rotors are made of a carbon-fiber-reinforced ceramic silicon carbide material . Their advantage comes in low mass and resistance to wear and heat. In fact, the rotors should never show any corrosion or require replacement for the life of the vehicle, when used in normal driving.

The vented and cross-drilled rotors on the Chevrolet Corvette ZR1 measure 15.5 inches (394 mm) in diameter in the front and 15 inches (380 mm) in diameter in the rear - making them among the largest carbon-ceramic rotors available on any production vehicle.

Clamping down on the high-tech rotors are six-piston front calipers and four-piston rear calipers, each painted a Chevrolet Corvette ZR1-exclusive blue. The front pads are equivalent in size to the largest on any production car with a single-pad design - double that of the Corvette Z06's 70-sq.-cm. front pads.

The brakes are visible through the Chevrolet Corvette ZR1's exclusive wheels: 20-spoke alloy rims that measure 19 inches in diameter in the front and 20 inches in the rear. They come standard with a bright, Sterling Silver paint finish and chrome versions are optional. The wheels are wrapped in Michelin Pilot Sport 2 tires developed specifically for the Chevrolet Corvette ZR1, measuring P285/30ZR19 in front and P335/25ZR20 in the rear.

Exclusive exterior

The Chevrolet Corvette ZR1 is instantly recognizable, with perhaps the most identifiable feature a raised, all-carbon-fiber hood that incorporates a clear, polycarbonate window. The window provides a view of the top of the engine's intercooler, with the legend "LS9 SUPERCHARGED" embossed on the left and right sides, and an engine cover with the Corvette crossed flags logo debossed at the front.

The underside of the hood has an exposed carbon-fiber-weave. Exposed carbon-fiber is used on the roof, roof bow, rocker molding and front splitter. These exterior components are protected by a specially developed glossy, UV-resistant clear coat that resists yellowing and wear.

Widened, carbon-fiber front fenders with specific, dual lower vents, and a full-width, body-color rear spoiler incorporating the center high-mounted stop lamp, are also unique to the Chevrolet Corvette ZR1. All of the exterior features of the car were developed to enhance high-speed stability and driver control.

Interior details

The Chevrolet Corvette ZR1's interior builds on the brand's dual-cockpit heritage, with high-quality materials, craftsmanship and functionality that support the premium-quality experience promised by the car's performance. The Chevrolet Corvette ZR1's cabin differs from the Chevrolet Corvette and Corvette Z06 with the following:

* ZR1-logo sill plates
* ZR1-logo headrest embroidery
* Specific gauge cluster with "ZR1" logo on the tachometer and a 220-mph (370 km/h) readout on the speedometer
* Boost gauge added to the instrument cluster and Head-Up Display

The "base" Chevrolet Corvette ZR1 (RPO 1LZ) comes with accoutrements based on the Chevrolet Corvette Z06, including lightweight seats and lightweight content. The uplevel interior package includes unique, power-adjustable and leather-trimmed sport seats (embroidered with the ZR1 logo); custom, leather-wrapped interior available in four colors; navigation system, Bluetooth connectivity and more.

By the numbers

In addition to the exterior cues and powertrain, Chevrolet Corvette ZR1 models will be distinguished from other Corvette models by their VIN. Each will carry a unique, identifying VIN digit, as well as a sequential build number. This makes it easy to determine the build number of a specific car - information treasured by enthusiasts and collectors. For example, a Chevrolet Corvette ZR1 with a VIN ending in "0150" would indicate it is the 150 th Chevrolet Corvette ZR1 built for the model year.

2011 Chevrolet Sail

Shanghai GM introduced the new Chevrolet Sail sedan, the first passenger car created in China by a Sino-foreign joint venture. The new small car was developed by Shanghai GM and the Pan Asia Technical Automotive Center (PATAC), both GM-SAIC joint ventures. In addition to being sold in China, the Chevrolet Sail will also be exported to other emerging markets.

Shanghai GM offers five variants of the Chevrolet Sail with the base model priced around RMB 60,000 (US$8,800). This marks a breakthrough in the under-RMB 70,000 (US$10,300) small car segment, where Chinese brands have traditionally been dominant.

"Our mission has always been to enable more individuals and families to realize their dream of owning a car," said Kevin Wale, President and Managing Director of the GM China Group. "With the Chevrolet Sail, we are setting a new standard for the lower-end small car segment while fully living up to the global standards of Chevrolet, one of the world's leading vehicle brands. The fact that the Chevrolet Sail will be exported is a testament to the capabilities of our product development organization in China."

Class-Leading, Fuel-Efficient Powertrains

The Chevrolet Sail is available with a choice of class-leading 1.2-liter S-TEC II and 1.4-liter S-TEC III engines. The 1.2-liter engine achieves best in class fuel economy under comprehensive road conditions of 5.7 L/100 km. It also generates power of 53.1 kW/L, enabling the Chevrolet Sail to go from 0 to 100 km/h in 12.9 seconds. The 1.4-liter engine offers power per liter of more than 54.3 kW/L, goes from 0 to 100 km/h in 11.9 seconds, and has fuel economy under 5.9 L/100 km.


The engines incorporate the Variable Geometry Intake System (VGIS), which provides smooth power delivery and torque across all engine speeds. Lightweight materials are used in the engine, transmission and body, further increasing fuel efficiency. The optimized friction coefficient in the transmission and tire rolling coefficient reduce energy loss caused by mechanical operation. In line with Shanghai GM's Drive to Green strategy, both engines meet China's Phase IV emission standard (as well as the Euro IV standard) and can be upgraded to meet China's Phase V emission standard.

Even though it is classified as a small car, the Chevrolet Sail ensures a fun driving experience. Its five-speed manual transmission offers smooth gear shifting. The sporty-looking steering wheel provides pinpoint handling and easy control, while the sporty yet solid chassis provides comfort and excellent handling. The driver enjoys maximum visibility courtesy of the Chevrolet Sail's large windshield, seats designed for local users and no-blind-spot rearview mirror.

Stylish Exterior, Spacious Interior

Like other vehicles wearing the Chevrolet bowtie, the Chevrolet Sail is sporty, enjoyable to drive and offers good value for money. The Sail features Chevrolet's trademark horizontal split grille with the gold Chevrolet emblem showcased in the middle. Three muscular sidelines provide the car a three-dimensional look. A unique short-in-front, long-in-back suspension brings a sporty edge to the exterior. The streamlined shape of the vehicle adds a dynamic styling element while reducing drag, for lower fuel consumption. The Chevrolet Sail is initially available in six exterior colors: Crescent Silver, Jasmine White, Sky Blue, Coral Red, Amber Orange and Starfish Blue.

The interior is likewise unique and all Chevrolet. It includes the brand's twin-cockpit design as well as a flexible, modern central control panel equipped with a radio, CD player and MP3 interface. Designers have added a sporty touch through a double-digital screen and chrome plating. The Chevrolet Sail's adoption of a central fuel tank, a short front and rear suspension, and arch-shaped doors maximizes interior space for up to five people. There are 24 interior storage compartments for added convenience.

Advanced Safety

The Chevrolet Sail is expected to achieve four stars in China New Car Assessment Program (C-NCAP) testing. The Chevrolet Sail's safety cage construction with crumple zones offers class-leading passenger protection. A steel frame surrounds the fuel tanks, for added safety. Dual air bags in front, a retractable steering column, antilock brakes with electronic brake-force distribution, child safety locks and a stronger child seat system are standard. The Chevrolet Sail also offers outstanding pedestrian protection.

Developed in China for Emerging Markets

The Chevrolet Sail was jointly developed by Shanghai GM and PATAC off a new architecture in accordance with GM's Global Vehicle Development Process (GVDP) and worldwide standards for engineering and quality. The development team for the Chevrolet Sail factored in local climate and driving conditions as well as local fuel quality and Chinese driving habits in the new model's design. The vehicle's assembly followed the DTS global C-BOB (best of best) standard.

The Chevrolet Sail was put through more than 2 million kilometers of testing in extreme hot and cold weather conditions.

To ensure that parts and components meet Chevrolet's international standards in terms of quality, service, technology and price, 95 percent of components were supplied by members of GM's global supply chain, with more than 40 percent coming from industry-leading component groups or their joint ventures.

GM's global quality management processes and regulations were also applied in R&D, procurement, quality recognition and manufacturing. Shanghai GM's paint shop adopted Generation 6 Zero-Emission Painting for the Chevrolet Sail. The vehicle meets all European Union environmental protection standards in terms of heavy metal proportion and the recycling rate of the full vehicle.

World-class Chevrolet Gold Tie Service will be offered to Chevrolet Sail buyers by Shanghai GM. Approximately 380 dealers in more than 200 cities across China will offer customers nine free services as well as 24-hour emergency assistance.

According to Shanghai GM President Ding Lei, "Several years ago, Shanghai GM made the strategic decision to broaden our customer base by developing the Chevrolet Sail. We improved cost efficiency while setting new quality, fuel efficiency and value standards for economical family cars. With the arrival of the Chevrolet Sail, we now have an entry in every major passenger car segment."
