2015 Chevrolet Silverado Improves Under New SAE J2807 Towing Standards

The 2015 Silverado has seen much improvements under the new J2807 towing standards.
The 2014 Chevy Silverado towed 300-500 pounds less than the 2015.

Towing capacity is to pickup truck what fuel economy is to hybrids and driving range is to electric vehicles. In the automotive world, most types of vehicles are intended for a specific purpose and will have an important factor that determines how well that vehicle accomplishes that purpose.

However, unlike hybrids and electric cars, pickup trucks do not have a standard method of determining how much weight a vehicle can actually tow. The problem was that previous methods of tow rating did not take into account different parts, options and passenger weight that negatively affects the total weight a truck can tow otherwise known as a truck’s Gross Combine Weight Rating (GCWR).

In a successful attempt to solve this problem, the Society of Automotive Engineers (SAE) created the J2807 standards. This is a unified system that requires automakers to test vehicles equipped with any options that normally have a 33 percent take-rate, 70 pounds of aftermarket hitch equipments and a driver and a passenger with a combined weight of 300 pounds.

Under this new standard, the 2014 Chevrolet Silverado and GMC Sierra base models dropped 300-500 pounds of towing capacity, while The V-6 regular cab trucks with four-wheel drive kept the same rating of 7,600 pounds as did certain versions of trucks equipped with the 6.2-liter V-8 and Max Trailering Package, which maintained the top rating of 12,000 pounds.

However, the 2015 Silverado and Sierra base models actually increased towing capacity under the J2807 standards with the four-wheel-drive V-6 models improving by 400 pounds for the Crew Cab and 500 pounds for the Double Cab, a pretty successful jump for Sierra and GMC.

Those of us at Nehls Chevrolet look forward to how the J2807 towing standards will improve the rating system and overviews of current and future pickup trucks.

Car and Driver Puts Chevy Volt Aerodynamics to the Test

Car and Driver put Volt aerodynamics to the test.
The Chevy Volt is the most aerodynamic all-electric car.

Aerodynamics is one of the most important features to consider when it comes to fuel economy. To have a fuel-efficient car, it needs to be able to cut through the air with ease, so Car and Driver decided to take five vehicles—the Chevrolet Volt, Mercedes-Benz CLA 250, Nissan Leaf, Tesla Model S P85, and the Toyota Prius—and measure their aerodynamic drag.

While the Volt has the third largest drag area, which is the size of the front multiplied by the drag coefficient, it still managed to be one of the two cars that lived up to its official drag coefficient number, the other being the Model S. Though the Model S was named the most aerodynamic choice of the batch, the Volt proved that it was the most aerodynamic all-electric car with a final drag coefficient of 0.28.

To check out just how streamlined Volt aerodynamics are, make sure you stop by Nehls Chevrolet today!

General Motors Hints at Changes for Eighth-Generation Corvette

General Motors teases big changes with eighth-generation Corvette.
The 2014 Corvette Stingray

 

We’re still basking in the glow of the seventh-generation Corvette redesigned for the 2014 model year, but is General Motors already admitting to an eighth-gen ‘Vette in the works? Not only has the automaker ‘fessed up. GM is hinting that big changes are on the way.

Before you get too upset thinking the beloved 2014 Corvette Stingray is going away any time soon, let us put your anxiety to rest. Based on production history, we at Nehls Chevrolet expect the current model to stick around for about seven more years at least.

Whenever the next all-new model comes, we’re interested to know what changes we can expect to see. We think the key is in what GM Global Product Chief Mark Reuss declined to say.

While he freely admitted to reporters that a next-generation Corvette was already being conceived, he remained mum on whether it could come equipped with a hybrid or even an electric powertrain.

Thanks to recent developments, hybrid and electric vehicle technology no longer automatically equates to reduced power. GM still has several years to continue advancing the technology.

With such an iconic car, GM’s engineers certainly have their work cut out for them as they craft the next Corvette. However, as much as we love the redesigned 2014 Stingray, we have full confidence they will find a way to make the eighth-generation Corvette a more efficient model with even better performance, but still classically Corvette.
