How A Summer Day Improved My Winter Testing

A hot afternoon at the lake inspired GM Engineer Nicholas Jahn to create a method for improved cabin warmth in the cold.

snowAs an engineer at GM, my day job is a huge part of my life. But as is the case with many of my colleagues, I have a more important job to worry about once I punch the clock – being a parent. It’s no surprise, then that many of us find inspiration in things our children do, say, or yes, sometimes ruin, and take those lessons back to our day job at GM. And some of these sources can be really surprising.

My moment of epiphany came at a very ironic time. As a GM Vehicle Thermal Systems engineer, one of my main responsibilities is making sure your car can warm the interior cabin as quickly as possible in the dead of winter. So you would never expect my moment to come while I was swimming in the lake behind my house on a hot summer day, but that’s exactly what happened.

I was out swimming with my one-year-old daughter, Ava, when it soon became very apparent that we had forgotten to put her in a swim diaper before taking her into the water. It was so apparent because shortly after coming in contact with the water, her diaper began to grow in size very quickly. Out of pure curiosity, I decided to look into what material caused this to happen.

After some internet searching, I came across sodium polyacrylate, the material responsible for absorbing the moisture in diapers, and found that it was commonly used as a substitute for snow for holiday decorations and hobbies like model trains and dioramas.

I quickly ordered a sample and after some testing, I realized that sodium polyacrylate not only looked just like snow, but also shared the packing and, most importantly, insulating properties of snow. After talking it over with my colleagues, we then developed a test using the material, which you can read more about here.

Being a parent can open your eyes up to many new things in life, many of which you may never expect. But as with anything, it’s what you learn from experiences that is the most important part. We at GM want to build vehicles that can handle anything life throws at them, which is why we take inspiration from places you’d least expect it, and use it to design, build, and sell the world’s best vehicles.

Chevrolet starts selling diesel Cruze in U.S.

General Motors Co.’s Chevrolet brand confirmed last month in May that it has started selling its first diesel passenger car in the U.S. since 1986 with its 2014 Chevrolet Cruze Clean Turbo Diesel.

Available for $25,695, the 2014 Chevrolet Cruze Clean Turbo Diesel offers a segment-leading 46 mpg highway, and can go 717 miles on one tank of diesel fuel.

Chevrolet Vice President of Marketing, Chris Perry, has stated that GM has sold a few Cruze diesels, which first are being sold in 13 metro markets selected for having a high diesel penetration. The vehicles will be available nationally in the fall 2013!

There is a growth in popularity for diesel technology in the U.S.  The Cruze diesel is powered by a 2-liter, four-cylinder turbocharged engine, has peak torque of 264 foot-pounds, and is certified at 151 horsepower, with more standard features.

“From a packaging standpoint what we offer in our vehicles, we think is a much more superior product,” Perry said. “As mentioned earlier, people getting into this marketplace are mostly concerned about performance and fuel economy. If you look at our numbers there, the Chevrolet clean turbo diesel offers better horsepower, better torque, more miles on tank of fuel, over 700 miles on tank of fuel. And the best news is we have achieved 46 miles per gallon highway.”

The Cruze diesel starts at $25,695.

Genuine replacement parts dependability – Chevrolet

I read a study last month that said, “The average age of cars and light trucks now in operation in the U.S. has increased to 10.8 years”. It was written by Polk, a leading global automotive market intelligence firm.

This study tells me that it is important for Chevrolet drivers to take care of the vehicles they buy. To do so, your vehicle needs parts and accessories specifically designed, made and tested to keep your Chevrolet  running at OEM (original equipment from manufacturer) peak performance and appearance—after all, they are the ones it was born with.

Each part works with the others to produce a single output. Many non-genuine parts may claim to be reliable, but they are not produced to meet GM’s engineering and material specifications. Compromise one part and you may unknowingly compromise a whole system.

Whether you are restoring an old favorite or personalizing your new baby, count on Chevrolet to provide genuine replacement dependability.

Visit us online to order parts & accessories, or stop by the dealership… either way, let us give you peace of mind knowing that you are taking care of your Chevy.
