2014 Chevy Trucks Park Atop Fountain in Comerica Park

Silverado, Equinox tower above ballpark where 3 million fans visit annually



DETROIT – It is a rite of spring even if the weather is only beginning to cooperate.

A Blue Topaz Chevrolet Silverado full-size pickup and a Crystal Red Metallic Equinox small SUV settled into their parking spaces atop the Chevrolet Fountain behind centerfield in Comerica Park on Thursday. Reaching their perches involved gingerly lifting each vehicle into place by crane – a three-hour process. 

“Chevrolet is the Official Vehicle of Major League Baseball and what better symbol can there be than having our vehicles in such a prominent place in our hometown stadium?” asked Paul Edwards, vice president, Chevrolet marketing.

Chevrolet has sponsored the fountain, which features an array of water displays and the sound of a tiger growling with each Detroit home run, for the last five seasons. The brand chooses core vehicles from its lineup to display each year.

While non-saleable pre-production vehicles took the spaces in previous years, this year’s Silverado and Equinox will be detailed and updated at the end of the season before going to dealer auction.

“Last year, we were able to showcase our vehicles to more than 3 million Tigers’ fans at Comerica Park and even more watching from home,” Edwards said. “Maybe these great family vehicles can inspire a few more home runs to centerfield this year.”

Chevrolet Designs for Pothole Perseverance



Carefully engineered test roads help customers absorb spring’s bumps


DETROIT Spring hasn’t arrived, but the potholes have. While no one plans to hit them, they are inevitable and in many cases unavoidable. More than an uncomfortable nuisance, they can damage tires, wheels and suspension components.

Chevrolet helps combat the effects of potholes by taking them head-on, testing vehicles such as Malibu and Silverado on carefully engineered roads within the General Motors Milford Proving Ground that are laced with manufactured potholes ranging from mildly annoying to chassis-rattling. The intentionally poor road conditions help engineers thwart the bumps a vehicle takes and tune suspensions to minimize discomfort to passengers.

“We have a wide variety of road surfaces that simulate real-world road conditions around the globe,” said Frank Barhorst, who supervises the Product Usage Measurements and Applications group at the Proving Ground near Detroit. “The range of test road surfaces goes from good to bad, so that we can find the most balanced condition for each vehicle we develop – and believe me, we’ve created some of the worst potholes you’ve ever seen.”

Potholes are most prevalent in the spring because the moisture in the small holes and cracks in the road during the winter alternates between freezing and thawing as temperatures change, causing expansion and contraction of the road surface. Then, the pavement breaks up under the weight of normal vehicle traffic. 

One of the major reasons vehicles sustain damage when they hit a pothole is because load is not transferred properly. The engineered potholes at Milford help experts re-create load conditions that occur when a vehicle hits one on a non-controlled surface. GM has collected that data for the past 40 years, using it to design and engineer new vehicles better able to absorb pothole abuse.   

The extreme durability tests extend beyond pothole-cratered pavement and includes terrain such as construction sites and off-road-driving environments for Chevy’s trucks and SUVs.  

“Every Chevrolet built globally goes through this type of testing. And we design our vehicles to absorb the load when they hit a pothole,” said Barhorst. “The data we collect on our test course helps us to integrate loads between interconnecting parts, and capture and fix potential problems as we design Chevrolets.”

While no technology will help drivers avoid every pothole, Chevrolet models share traits – such as robust body structures – that reduce vibrations generated by sudden, harsh impacts. The strong body structures also enable engineers to tune the suspensions more precisely, for smoother, more controlled driving experiences that help mitigate the effects of smaller and moderate potholes.

Chassis and suspension updates inspired by the all-new 2014 Impala also contribute to the a dynamic driving experience in the 2014 Malibu, including rebound springs in the struts on 2.5L-equipped models. More refined calibration of the dampers results in a smoother overall ride and improves body roll control and weight transfer during acceleration or turning. That helps keep the wheels planted, contributing to a more precise, controlled feel – especially while cornering.

Tire and wheel design and construction also play a vital role in managing potholes. GM engineers its tire technology specifications with an eye toward fuel economy, quietness, tread wear, braking distances and the ability to withstand potholes.

“On the wheel side, we’ve developed a premium process for flow-formed rims,” said Dave Cowger, GM Tire & Wheel Systems Engineering. “On the tire side, we’ve made improvements to the body side including the cords in the tires, which make the tires stronger and allow the vehicle to withstand impact better.”

The team that engineered the new Silverado went to extremes to ensure it would exceed the demands of truck customers. GM’s new full-size trucks underwent more than 6 million miles of durability testing at Milford, over the deserts and mountains of Nevada and across the frozen flats of Kapuskasing, Ontario. That’s equivalent to 240 trips around the earth. In addition, the trucks accumulated more than 7 million real-world miles during final testing, bringing total test miles to more than 13 million.

 Chevrolet Certified Service offers these tips for avoiding and managing potholes:

  • Always inflate tires to the number on the tire inflation placard on the inside of the driver’s door opening
  • Tire inflation should be checked cold, before driving  
  • Each 10-degree F change in ambient temperature changes the effective inflation pressure by 1 pound. This means during the course of a winter day going from 40 degrees F at noon to 0 degrees F at night, tire pressure can drop 4 pounds, enough to affect its ability to resist pothole damage  
  • Use winter-rated tires
  • Watch for street hazards
  • Remember that dirty headlamps and worn wipers hamper visibility
  • If you hit a pothole, visibly check your wheel and tire for obvious damage and have your Chevrolet dealer check to see if the vehicle needs a re-alignment or if there is suspension damage.

Engineering, Advanced Materials Help Slim Down Colorado




  • New midsize pickup is 880 to 1,400 pounds lighter than full-size pickups


  •       Lightweight high-strength steels, aluminum, play key roles in mass reduction

DETROIT – Proving there is more than one way shed pounds, the 2015 Chevrolet Colorado uses engineering techniques and lightweight materials to create true pickup capability in a mass-efficient midsize package.
The 2015 Colorado 4x4 crew cab, expected to be the most popular version of the new trucks, weighs 880 to 1,400 less than a full-size truck.
This weight saving is a result of the slightly smaller overall dimensions of the Colorado, along with extensive use of lightweight materials, including high-strength steels and aluminum. The outcome is a truck designed to be the most fuel-efficient in its segment. Chevrolet expects EPA fuel economy estimates for Colorado this summer.
The Colorado will begin arriving in showrooms this fall at the same time as the new Ford F-150, setting up a sharp contrast between two strategies for reducing the weight of pickups.
“When it comes to building lighter pickups, there is more than one answer,” said Jeff Luke, executive chief engineer. “Building on our experience with the new Silverado, we engineered the Colorado to be highly mass-efficient, while still providing the performance, capability, dependability and features that midsize truck customers are asking for.”
Efficient size that’s right for many customers
In overall size, Colorado fits neatly below the Silverado 1500 in the Chevrolet lineup. The short-bed crew cab is 212.76 inches long, 17 inches shorter than a comparable Silverado 1500, making it an easier fit in many garages.
Colorado’s overall width of 74.3 inches is five inches narrower than Silverado and two inches wider than the Equinox, providing easier maneuverability around town with a surprisingly spacious interior.
This slightly smaller package comes with real muscle, though. Based on GM’s latest testing, Colorado is expected to lead the midsize segment with up to 6,700 pounds of available towing capability.
“For many customers, a midsize pickup is simply a better solution,” said Luke. “You get the versatility and capability of a truck in a package that is fun to drive and easier to maneuver and park.
“Colorado will meet the unique needs of midsize pickup customers, while also providing an attractive, cost-effective alternative for anyone seeking a more fuel-efficient pickup.”

Intelligent use of lightweight materials
In creating Colorado, GM engineers chose materials that would make the most of the strength, safety and refinement of the truck, while balancing dependability   and cost of repairs and total ownership.
Like Silverado, Colorado extensively uses lightweight, high-strength steels. Fully boxed frames formed primarily from high-strength steel reduce weight and increase stiffness for a quieter ride and better handling.
Key areas of the body structure also benefit from high-strength steels, reducing mass and enhancing strength and safety. Overall, about 71 percent of the body structure is comprised of high-strength steels.
The pickup box consists of roll-formed steel, which is lighter and stronger than traditional stamped steel.
Major aluminum components include the hood, front steering knuckles, and cylinder heads and engine blocks for both the 2.5L four cylinder and 3.6L V-6. Reflecting the attention to weight savings found throughout the Colorado, the aluminum heads for the V-6 feature integral exhaust manifolds, which save about 13 pounds over traditional cast-iron manifolds.
The front of Colorado features a composite grille opening reinforcement with active shutters that seals the front of the truck, reducing aerodynamic drag and improving cooling performance. Another weight-saving feature, electric power steering, also helps improve steering assist for easier maneuverability in tight situations.
Because of its mass-efficient design, Colorado engineers skipped the cost and complexity of turbocharging Colorado’s four-cylinder and V-6 engines.
In addition to the lightweight aluminum cylinder heads and blocks, both engines feature direct fuel injection and continuously variable valve timing for better performance and more-efficient operation. Based on current GM testing, the standard 2.5L four is estimated at 193 horsepower, while the available V-6 is estimated at 302 horsepower.
Because customers seeking a lighter truck shouldn’t have to compromise on Chevrolet’s legendary dependability, both the Colorado and its engines have been tested and validated to the same tough standards as the full-size Silverado.

Five Reasons Silverado V6 is The Little Engine That Can




DETROIT –Largely because of the strength and refinement of the new EcoTec3 V-6, sales of V-6 Silverados account for 20 percent of light-duty pickup sales, up from about 5 percent for the previous model.

1)  Purpose built for pickup use, with class-leading standard torque and towing
The Silverado standard 4.3L EcoTec3 V-6 has one purpose – providing budget-conscious pickup customers a great standard engine. Its large 4.3-liter displacement provides class-leading torque (305 lb-ft) and available towing (7,600 lbs.) for a standard V-6, while its aluminum cylinder heads and block saves weight. Its ability to operate on four cylinders under lighter loads helps improve fuel efficiency.

2)  For many returning customers, comparable performance with much better economy
The average age of a full-size pickup on the road is about 10.4 years. Owners of these trucks coming back into the market will find Silverado’s new EcoTec3 V-6 performs comparably to the V-8 engines powering many of their trucks, and with significantly improved fuel economy.

4)  Innovative technology for every customer
  Silverado’s 4.3L EcoTec3 V-6 offers the same advanced engineering as Silverado’s optional 5.3L and 6.2L V-8 engines:
  • Direct fuel injection, which precisely measures fuel directly into each cylinder, making the most of combustion for improved power, torque and efficiency.
  • Continuously variable valve timing, which adjusts the opening and closing of the valves to help improve low-end torque.
  • Active Fuel Management, which seamlessly switches to four-cylinder operation at lighter loads to help save fuel.
5)  An all-new engine with deep, strong roots
Silverado’s EcoTec3 V-6 was all-new for 2014, but it builds on nearly 60 years of experience with small-block Chevy truck engines. Chevy small-block engines are proven, year-in and year-out, under the toughest conditions, on job sites and race tracks around the world.
This fifth generation of these legendary engines incorporate advanced technologies such as race-proven aluminum engine blocks for long life; six-bolt main caps with cross bolts for quieter, smoother operation, and oil-jet cooled pistons for more consistent power under high-heat, high-load situations.
The Chevrolet Silverado also comes with the industry’s best pickup coverage as standard, including 2-year/24,000-mile recommended maintenance, 3-year/36,000-mile bumper-to-bumper limited warranty and 5-year/100,000-mile powertrain limited warranty, Roadside Assistance and Courtesy Transportation.
