2015 Chevrolet Trax

After the obligatory product presentation for the 2015 Trax, I caught up with Steve Majoros, Chevrolet's director of marketing for crossovers and cars, and asked him to elaborate on which markets his planners believe will be the hot starters for this tiny CUV. Without much hesitation, Majoros began to click off traditional sales havens for Subaru, namely, New England and the snowy bits of the East Coast, Colorado and the Pacific Northwest. That news might not surprise you, but it did me. Perhaps it's something as basic as the Trax's tall-hatchback looks, or the emphasis Chevrolet put on the urban driving cycle during my test in San Diego. But before my chat with Majoros, I'd considered this a crossover pointed at the Millennial city mouse more than his bumpkin cousin. But a closer look had me re-examining the granola cred of Chevy's smallest crossover. Having spent my fair share of time in New England and around New Englanders, I started by mentally listing the Trax's Subaru-like traits: practicality, thrift, all-weather ability and, well, just a dash of ugliness. (I suppose a hatchback needn't always be ugly to sell in Maine, or Boulder or Portland... but a 'distinctive' face doesn't seem to hurt.) After a day of driving through sunny San Diego and its surroundings, I can say that Trax makes an interesting case for itself against the standard bearers of the L.L. Bean set, but I'm less sure of its argument for young urbanites. The Trax looks a lot like an Equinox whose suit shrunk in the wash. Chevy's has downsized its own, rather conservative crossover styling to fit the proportions of the subcompact Trax; to my eyes, it looks a lot like an Equinox whose suit shrunk in the wash. That's fine for offering a cohesive look for the Chevy family of crossovers, but it seems out of step with the rest of the segment. If the Trax's current competitive set were the cast of a high school-based TV show, the Kia Soul would play the lovable nerd, the Nissan Juke perhaps the outsider musician and the Subaru XV Crosstrek the athletic outdoorsy kid. Chevy may see the Trax as the hipster chick wearing intentionally ironic mom jeans, but to me the styling is a little too on the nose; more like an actual grownup trying to hang with the kids. These mom jeans are genuine. Per my earlier point, that quasi-conservative look may be just fast enough for staid New Englanders, but I have a hard time seeing the bluff, big-Bowtied front end playing in Bushwick or Wicker Park.

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.
