Michael Jordan's cars showcased in 'The Last Dance' documentary

After the masses begged and pleaded for an early release, ESPN finally unlocked the doors to the biggest production in company history last month. Episodes 1 and 2 of The Last Dance, a 10-part documentary special about Michael Jordan, the Chicago Bulls, and the 1997-1998 season, was released at last on April 19, 2020. Each week since, two new episodes have aired on Sunday nights, and the next two, episodes 7 and 8 are scheduled to drop this weekend on May 10. With unprecedented video access to MJ, who became averse to the media during his playing days, a byproduct from The Last Dance is a look at some of Jordan's cars. The Goat's taste ranges across a number of brands, but they all had one thing in common: performance as a top priority. Below, we have listed the rides that have already appeared in the series, and each week, we will update with new car cameos. Chevrolet Corvette C4 The photo above somewhat epitomizes one of the themes of The Last Dance. Everybody, whether that was men, women, children, franchise owners, reporters, coaches, teammates, or opponents, wanted a piece of Jordan. If that meant stopping in the middle of the road to get an autograph, then so be it. Around town, MJ was fairly easy to spot due to his flashy cars that occasionally wore Bulls red. Jordan has driven numerous Corvettes throughout the years, but the C4 is unique in that it was Chevy's top ride when Jordan signed an endorsement deal with the American company during his rookie year in 1984. Two famous photos, one in front of the Chicago skyline, show him standing next to a C4 with the license plate "Jump 23." This exact car, however, came later, as indicated by the squared-off taillights. He went on to star in a number of Chevrolet commercials with vehicles such as the Blazer and S-10 pickup truck. Chevrolet Corvette C5 The most notable Corvette His Airness ever owned was likely the C4 40th Anniversary ZR-1, but he also drove a C5 coupe at one point. Roughly nine minutes into the first episode, Jordan is seen driving the chrome-wheeled targa top into the parking lot at the Berto Center, the Bulls old practice facility.   Ferrari 550 Maranello Roughly three minutes into episode four, viewers get a glimpse of Jordan's exotic taste in the form of a red Ferrari 550 Maranello.

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.

Weekly Recap: BMW rolls out ambitious plug-in hybrid electric plan

"We believe that for the United States, this is going to be very important." – Julian Arguelles Let there be no doubt, BMW is serious about electric vehicles. The German automaker said this week it will make plug-in hybrid versions of all of its core models, an aggressive move that demonstrates its commitment to electric propulsion systems. BMW did not specify which vehicles will get the plug-in systems or provide a timeline for when they will arrive. But the announcement is clearly more than blustering, and the company revealed a 3 Series plug-in prototype this week at an event in France. BMW said the 3 Series uses a version of its 2.0-liter turbocharged four-cylinder engine (240 horsepower, 300 pound feet of torque) with an electric motor sandwiched between the engine and transmission in place of the torque converter. It has an all-electric range of 22 miles. A plug-in X5 with the same powertrain was also displayed alongside the 3 Series, though the X5 has been on the auto-show circuit for more than a year, including a recent stop in Los Angeles. Those two vehicles use "eDrive," and BMW's plans represent the first widespread transfer of its technology from development of the i3 and i8 models to more mainstream products. BMW said it's developing electric powertrains so they can be deployed rapidly across its range, and they are flexible enough to be used with fuel cells in future products. Enticingly, BMW is also working on a "Power eDrive" system, which debuted in a 5 Series GT concept at the event in France. This setup has two electric motors powered by a 20-kilowatt-hour battery pack, and when teamed with a four-cylinder turbo, pump out about 670 hp. Reinforcing BMW's commitment, the company will add more than 200 jobs at its factory in Dingolfing, Germany, to support electric-vehicle development. The moves come as BMW and other automakers diversify their portfolios while fuel economy and emissions regulations are getting tighter around the world. The United States has set a 54.5-mpg CAFE requirement for the 2025 model year. BMW said the electric vehicles were developed with an eye toward the US market, its government policies and its wide-ranging commuting styles. "We believe that for the United States, this is going to be very important," spokesman Julian Arguelles said. Ben Scott, a senior analyst in London with automotive research firm IHS, said BMW's moves are expensive – but necessary – to keep pace with the market.
