2014 Chevrolet SS: Performance Sedan with Racing DNA

2014-chevrolet-ss-004-opt
As Chevrolet's first V-8, rear-wheel-drive performance sedan since 1996, the new Chevrolet SS is designed to deliver performance on the street and on the track. The 2014 Chevrolet SS will debut this weekend at the Daytona International Speedway as the SS racecar makes its NASCAR debut during the Daytona 500.

"The Chevrolet brand was largely built on the strength of rear-drive performance sedans, yet it's been 17 years since we've offered one," said Mark Reuss, president of General Motors North America. "The all-new Chevrolet SS fills that void and fills it better than any other vehicle in the brand's rich history. The comfort, convenience, spaciousness and V-8 power make the SS a total performance package unlike any other on the road today."

The Chevrolet SS benefits from the proven, race-tested, global rear-wheel drive architecture that is the foundation for the Camaro, Caprice Police Patrol Vehicle and Holden's VF Commodore.

The Chevrolet SS is powered by the LS3 Chevrolet V-8, expected to deliver 415 horsepower and 415 lb-ft of torque. Also used in the 2013 Chevrolet Corvette, the LS3 displaces 6.2 liters, more than the 5.5-liter V-8 powering the Chevrolet SS NASCAR competitors.

The LS3 is married to a six-speed automatic transmission, which can be shifted manually using TAPshift paddles mounted on the steering wheel. With an aggressive 3.27 final-drive ratio, the Chevrolet SS accelerates from 0 to 60 mph in about five seconds – making it one of the quickest sedans on the market.

To ensure that it turns and stops as well as it accelerates; the Chevrolet SS also features a sport-tuned chassis, including:
• MacPherson strut front and multilink independent rear suspension geometry
• Electronic power steering system, optimized for sport driving
• Standard Brembo brakes, with ventilated, 355-mm rotors and two-piece, four-piston front calipers
• Forged aluminum wheels, wrapped in ultra-high-performance Bridgestone tires: 19 x 8.5 inch wheels with 245/40ZR19 tires in front; 19 x 9.0 inch wheels with 275/35ZR19 tires rear

Handling is also improved by a near 50/50 weight distribution, and a low center of gravity – made possible in part by the aluminum hood and rear deck lid that are 30 percent lighter than traditional steel panels.

"Our goal was to create a car that delivers incredible grip and handling balance while cornering, while still being comfortable to drive on the road," said David Leone, executive chief engineer GM global programs. "The perfect weight balance and lower center of gravity were a big part of that goal because it enabled the team to tune for a more comfortable highway ride without sacrificing handling or driver confidence while cornering at the limits."

Similarly, the design of the SS blends performance cues and premium details.

"From every angle, the Chevrolet SS says power and performance," said John Cafaro design director Chevrolet passenger cars and small crossovers. "The combination of an aggressive rear-wheel drive stance and body-side attitude with the right balance of detail and refinement inside and out are the perfect home for Chevrolet's V-8 performance package."

The staggered front and rear wheels, which are pushed out to the corners, enhance the sporting, muscular stance of the SS. Up front, the aluminum hood features a subtle "power bulge" hinting at the power of the engine underneath. At the rear, the tapered, tear-drop shape contributes to improved aerodynamic performance. Premium cues include jewel-like chrome accents, standard high-intensity discharge headlamps and light-emitting diode daytime running lights.

The spacious interior of the SS will comfortably accommodate five adults, with 42 inches of front legroom, and 39 inches of rear legroom. Leather seating surfaces are standard, as are eight-way power adjustable front bucket seats with additional side bolstering that hug the driver and front passenger in tight-handling situations. The SS emblem is prominently stitched onto the soft-touch instrument panel which features two types of chrome finishes – a satin gloss and a bright chrome. At night, the interior is illuminated by ice blue ambient lighting.

An integrated center stack includes infotainment, climate and other vehicle controls. The Chevrolet SS also offers a long list of technology features as standard equipment including:
• Color, in-dashboard touch screen that supports Chevrolet MyLink and the next-generation navigation system
• Bose® Nine-speaker premium sound system
• Color heads-up display
• Push-button start
• StabiliTrak Electronic Stability Control
• Forward Collision Alert
• Lane Departure Warning
• Side Blind Zone Alert
• Rear-vision camera Rear Cross Traffic Alert

The SS is also the first Chevrolet to offer Automatic Parking Assist, which provides hands-free parking help. This efficient 'hands-free' parking assistant uses the ultrasonic sensing system to detect the width and depth of either parallel or reverse right-angle parking spaces. While the driver controls the throttle, transmission, and brake, the Automatic Parking Assist controls the steering inputs necessary to neatly park the Chevrolet SS.

The 2014 Chevrolet SS will be available in the fourth quarter of 2013, with prices set closer to the on-sale date. When it arrives in showrooms, the SS will join the Corvette and Camaro, whose combined sales have made Chevrolet America's favorite performance brand for the last two years.

Cruze Clean Turbo Diesel Delivers Efficient Performance

The all-new 2014 Chevrolet Cruze Clean Turbo Diesel features an advanced 2.0L clean diesel engine that will offer an estimated 42 mpg highway with an automatic transmission and expected best-in-segment range based on GM testing. Clean diesels generate at least 90 percent less Nitrogen Oxide (NOx) and particulate emissions when compared to previous-generation diesels. It is the cleanest diesel passenger car engine ever produced by General Motors.
Cruze’s 2.0L turbo-diesel is based on proven architecture already used in European models, where approximately 40 percent of all Cruze models sold feature a diesel engine. Collaborating with Italian and German engineering groups, GM’s diesel experts in the United States adapted the engine to accommodate more stringent diesel emission standards and a wider range of driving conditions – including colder climates and higher altitudes – for the United States and Canada.
“This Cruze Clean Turbo Diesel represents a new era in diesel performance for American cars,” said Jens Wartha, GM chief engineer. “We’ve adapted a proven engine from Europe, the world’s diesel capital, and married it with the emissions-reducing technology that was perfected in the United States. It’s a great example of how Chevrolet’s global resources work harmoniously to produce the right product at the right time and for the right market.”

Cruze’s new 2.0L turbo-diesel delivers a segment-leading estimated 148 horsepower (110 kW) and estimated 258 lb-ft of torque (350 Nm). Peak torque is achieved at a low 2,000 rpm for a sustained feeling of power on demand at almost all speeds – particularly when passing or entering a freeway onramp.
The engine has an overboost feature capable of increasing torque to an estimated 280 lb-ft (380 Nm), for stronger acceleration periods of about 10 seconds.
“With the benefit of continuous refinement in other markets, the 2.0L turbo-diesel comes to the United States and Canada with performance that will impress,” said Mike Siegrist, assistant chief engineer. “It is powerful, efficient and clean. It will change perceptions of what a diesel car can be while giving customers another fuel efficient choice in the Cruze lineup.”
Cruze models in the United States and Canada offer a 1.4L turbo, a 1.4L Eco model and 1.8L naturally aspirated engine.
The 2.0L turbo-diesel engine provides greater fuel economy than a comparably sized gasoline engine through greater thermal efficiency, a higher compression ratio and an unthrottled combustion process. It features an iron cylinder block and a forged steel crankshaft, each designed to stand up to the greater cylinder pressures that come with a turbo-diesel engine.
A lightweight aluminum cylinder head and aluminum intake manifold contribute to the engine’s comparatively low weight of 408 pounds (185 kg), helping the Cruze Clean Turbo Diesel deliver a balanced ride with outstanding handling characteristics. Additional highlights include:
  • Dual overhead camshafts with four valves per cylinder and maintenance-free hydraulic lifters with low-friction roller-finger followers
  • Quiet belt-driven cams/valvetrain with high-strength belt material and tensioner rated for 100,000 miles
  • High-strength aluminum pistons with reinforced top ring and integral combustion bowl design
  • Central direct injection, with the injector positioned in the middle of the cylinder, with the bowl in the piston serving as the combustion chamber. This enables a high 16.5:1 compression ratio that enhances power and combustion efficiency
  • Variable-swirl intake manifold design, which optimizes air charge mixture motion in the cylinders for a more-efficient combustion that enhances performance and reduces emissions
  • Common-rail fuel system with Piezo fuel injectors that create multiple injections per combustion for greater performance, combustion efficiency and quietness
  • Variable-nozzle turbocharger that broadens the engine’s torque curve, particularly at low rpm, and supports greater high-rpm horsepower. It is mounted close to the exhaust outlet of the engine for quicker “spool up” of the turbine and faster “light off” of the exhaust catalyst
  • Intercooling system produces a cooler, denser air charge for greater power
  • Piston oil jets that help reduce friction and optimize piston temperature for greater performance and efficiency
  • Turbocharger bearings are oil-lubricated and cooled via an oil cooler
  • Variable-displacement oil pump helps save fuel by optimizing the oil pressure, which reduces friction
  • Vacuum pump designed for lower engine friction
  • Ceramic glow plugs, which provide greater cold-start performance over conventional metal glow plugs (an engine oil heater is offered for cold climates)
  • B20 bio-diesel compatibility.
Quiet, smooth performance is enabled by a number of features on and around the engine. There are also sound-absorbing features added to the Cruze, specific to the diesel model, including a unique dash mat, hood blanket and more.
A precise exhaust gas recirculation control system features a high-capacity cooler and bypass feature that enable the engine to meet United States and Canada’s tough diesel emissions regulations. There is also an exhaust after-treatment system is similar to what is used on Chevrolet’s heavy-duty trucks and vans equipped with the Duramax diesel, including a diesel particulate filter and urea injection, that helps make the 2.0L the cleanest diesel passenger car engine ever from GM.
An approximately 4.5-gallon (17 liters) tank in the Cruze Clean Turbo Diesel holds enough diesel emissions fluid to provide at least 10,000 miles (16,000 km) of driving between refills. The system is also designed for servicing to coincide with oil changes, for greater convenience.

Monday Maintenance Tip: Don’t mix coolants

Avoid mixing coolants that are different in color. If your coolant is pink, don’t add a green formulation to it. Otherwise, you’ll end up with a thick solution that won’t do its job. Use only the coolant specified in your owner’s manual.
