2017 Chevy Bolt Prototype Quick Spin [w/video]

To say that there's a lot riding on the upcoming Chevy Bolt doesn't quite get at how important this all-electric vehicle could be for GM. To say that there's a lot riding on the upcoming Chevy Bolt doesn't quite get at how important this all-electric vehicle could be for GM. We are entering a new phase for EVs in the US, and it's one where there will be more than one 200+ mile range electric model that will cost around $30,000-$35,000. The two obvious first entries are the Tesla Model 3 and the Bolt, but you can bet your Level 2 charger that Nissan will be joining the party as well, along with all sorts of as-yet-unannounced entries from other automakers. The main change that all of these longer-range EVs will bring is – potentially – to make plugging in your car a mainstream thing. And if the mainstream is in play, then there's money to be made, and you're going to need one heck of an EV to get people to pick your car instead of someone else's. So, yeah, the Chevy Bolt could be a big deal. And today we not only got a bit more information about the car but we also got to go on a really short test drive in a prototype version outside of the Las Vegas Convention Center as part of CES 2016. The "drive" took place in a closed-off parking lot and my two laps through the cone course took less than three minutes, but I can still say that it looks like GM will be bringing a solid option to the marketplace soon.

One of the pleasant surprises in the Bolt prototype is the ability to drive with just one pedal. When in D, the Bolt coasts a bit, which is nice for highway driving, but if you shift into L, the regen becomes wonderfully strong. Strong enough that you don't need to engage the brakes at all if you're in standard city traffic, with lots of gentle stops and starts. If you want even more stopping power without getting the brakes involved, the Bolt also has the regen-on-demand feature that was introduced in the Cadillac ELR and works great in the second-gen Chevy Volt. When you pull the paddle on the left back side of the steering wheel, the electric motor instantly becomes a generator and the Bolt turns forward momentum into energy for the battery pack. It will even bring the car to a complete stop and then hold it when you release the paddle.

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.

Chevy, GMC have electric pickups coming. Is Cadillac next?

GMC already has an uber-expensive electric pickup in the Hummer EV. By now you've no doubt seen the 2024 Chevrolet Silverado EV. It's a pickup. It's electric. It looks a little bit like an Avalanche. Hmm. You know what else was a pickup that looked a little bit like an Avalanche? Why, the Cadillac Escalade EXT, of course.  Cadillac Escalade EV-T yes or no?https://t.co/R1AXThRzIG@therealautoblog @Cadillac — Byron "Don't do anything Byron says. Ever" Hurd (@Byron_AB) January 7, 2022 So, hypothetically, if Cadillac were to build an Escalade EXT with an upmarket interior, Super Cruise, a minimum of 300 miles of range, 10,000 pounds of towing capacity, a locking frunk and 5-passenger seating, plus all of the nifty doodads and gadgets we've already seen on the Silverado ... would it sell?  OK, this isn't entirely hypothetical. In fact, I received a survey from Cadillac this morning asking just that. It's an interesting question. And it's one we're putting to you, the readers. So, what say you? Cadillac Escalade EV-T? Yes or no? Related video:
