US presidents used to ride around in open convertibles. Today, President Joe Biden is driven in a 20,000-pound, $1.5 million armored Cadillac known as "The Beast." Take a look at how presidential limousines have changed through the years. Presidential cars replaced horses and carriages in the early 20th century.

The administration of President Theodore Roosevelt, who succeeded McKinley after his 1901 assassination, was the first to include a government-owned car. In 1941, President Franklin D. Roosevelt became the first president to ride in an armored vehicle — a limousine that previously belonged to gangster Al Capone. President Franklin D.

GM won't really kill off the Chevy Volt and Cadillac CT6, will it?

General Motors is apparently considering killing off six slow-selling models by 2020, according to Reuters. But is that really likely? The news is mentioned in a story where UAW president Dennis Williams notes that slumping US car sales could threaten jobs at low-volume factories. Still, we're skeptical that GM is really serious about killing those cars. Reuters specifically calls out the Buick LaCrosse, Cadillac CT6, Cadillac XTS, Chevrolet Impala, Chevrolet Sonic, and the Chevrolet Volt. Most of these have been redesigned or refreshed within the past few model years. Four - the LaCrosse, Impala, CT6, and Volt - are built in the Hamtramck factory in Detroit. That plant has made only 35,000 cars this year - down 32 percent from 2016. A typical GM plant builds 200,000-300,000 vehicles a year. Of all the cars Williams listed, killing the XTS, Impala, and Sonic make the most sense. They're older and don't sell particularly well. On the other hand, axing the other three seems like an odd move. It would leave Buick and Cadillac without flagship sedans, at least until the rumored Cadillac CT8 arrives. The CT6 was a big investment for GM and backing out after just a few years would be a huge loss. It also uses GM's latest and best materials and technology, making us even more skeptical. The Volt is a hugely important car for Chevrolet, and supplementing it with a crossover makes more sense than replacing it with one. Offering one model with a range of powertrain variants like the Hyundai Ioniq and Toyota Prius might be another route GM could take. All six of these vehicles are sedans, Yes, crossover sales are booming, but there's still a huge market for cars. Backing away from these would be essentially giving up sales to competitors from around the globe. The UAW might simply be publicly pushing GM to move crossover production to Hamtramck to avoid closing the plant and laying off workers. Sales of passenger cars are down across both GM and the industry. Consolidating production in other plants and closing Hamtramck rather than having a single facility focus on sedans might make more sense from a business perspective. GM is also trying to reduce its unsold inventory, meaning current production may be slowed or halted while current cars move into customer hands. There's a lot of politics that goes into building a car. GM wants to do what makes the most sense from a business perspective, while the UAW doesn't workers to lose their jobs when a factory closes.

GM recalls full-size truck, SUVs and vans over faulty shifter mechanism

Twelve different General Motors vehicles from the 2013 model year, up to 54,686 units in total, are being recalled over two potential issues with their steering columns. The models in question, all full-size trucks, SUVs or vans, are the: Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Express, Silverado, Suburban, Tahoe, and GMC Savana, Sierra, Yukon and Yukon XL.
The affected vehicles were built with a fractured parking lock cable or "a malformed steering column lock actuator gear in the lock module assembly." As a consequence, they could shift out of park without the brake pedal being applied or with the key removed or in the off position.
A bulletin from the National Highway Traffic Safety Administration indicates that the recall should begin on January 17. GM will notify owners, at which time they can take their vehicles to their dealers for repair free of charge. Have a look at the bulletin below for more information.
