GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

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.

One of the world's largest muscle car museums is auctioning off its cars

Rick Treworgy's Muscle Car City is one of the biggest collections of high-performance American cars in the world. With over 200 cars of mostly GM makes, it's a mecca for fans of the golden age of Detroit iron. Unfortunately, the museum will be shutting its doors for good on Jan. 17 and auctioning off most of its assets with no reserve. The collection is, to put it bluntly, astounding. Advertised as a combined 65,000-plus horsepower, it occupies a 60,000-square-foot retail space in Punta Gorda, Fla., in a former Walmart store. It make sense when you learn that founder Rick Treworgy made his fortune in the commercial real estate business. As a hobby, he began to amass a truly jaw-dropping collection of muscle cars, filling out a collection that often has every year of a particular model represented, or a grouping of the rarest and highest-performance option packages of that year or model. Often, Treworgy bought placeholders while scouring the country for even rarer versions. It helps that Muscle Car City also houses a showroom where unwanted cars are sold, as well as its own speed shop that stocks plenty of parts. There's even a '50s-style diner called Stingray's Bar and Grill. According to a 2014 episode of Car Crazy, Treworgy has 80 Corvettes alone, more than the actual Corvette Museum. Among them are 20 models from 1967, one of Treworgy's favorites. The rest span the decades from 1954 (he once had a '53 but sold it) to a recently acquired 2020 C8, which, according to The Drive, has only 300 miles on the odometer. You like Impalas? There are models of every year from 1958 to 1969. El Caminos? He's got 'em from 1964 to 1972. Novas? Every year from 1963 to 1970 is represented. Most are the more desirable examples of each breed, with four-speed transmissions, the biggest blocks, and unicorn option packages like a factory 1965 Z16 SS396 Chevelle, one of 200 that were ordered off-menu at Chevy dealerships. And don't even get us started on the Camaros, which include not one, but two COPO 1969s. Treworgy even owns the only known surviving example of a 1936 Chevrolet Phaeton, of which only seven were built. On top of it all, many of these cars are concours quality and have won awards at prestigious car shows. While it's sad to see a collection like this broken up, Treworgy told The Drive that he'd been planning to retire next year anyway. However, the COVID-19 pandemic sped up those plans, greatly reducing the number of visitors to his museum.
