First Cadillac ELR rolls off the line

Gearing up for the Belle Isle Grand Prix this weekend, General Motors invited some of the Chevrolet and Cadillac racecar drivers out to its Detroit-Hamtramck assembly plant. While there, the racers - including IndyCar Driver and Chevrolet Volt owner, Simona De Silvestro - witnessed the very first 2014 Cadillac ELR to roll off the assembly line.
These vehicles are not destined for customers, however, but instead pre-production units will be used by engineers for testing purposes. Actual production of ELR consumer models is expected to commence closer to the end of this year. As a refresher, this range-extended electric Cadillac shares much of its powertrain with the Volt but will have a sportier coupe design inspired by the Converj Concept. De Silvestro manged to snap a few images of here own, which you can see in the gallery below.

GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.

President Trump's new limo spotted testing at high speed

What you're looking at is no ordinary limo. Look past the swirly camouflage and you'll see what appears to be a Cadillac, but don't let those looks fool you. This is the new Beast, otherwise known as Cadillac One, and codenamed by the Secret Service as Stagecoach. This is the car that will shuttle President Trump to and fro. It's hard to get a sense of scale from these images, but this car is huge. It's very likely built atop a heavy-duty truck platform, which is necessary due to the thick armor-like bodywork that's hermetically sealed to keep POTUS safe and sound. It's hard to tell for certain, but it appears this Beastie is riding on Goodyear Regional RHS II tires, which would otherwise be used on trucks and buses. Translation: this thing is heavy. The Beast is ostensibly badged as a Cadillac, and it wears the latest version of Caddy's corporate grille, badge, and upright headlamps at the front. From the rear, there's a hint of Rolls-Royce Phantom, with rear glass that tapers elegantly into the deck lid. In between is a massive slab-sided passenger compartment that's rumored to seat as many as seven passengers. These shots were snapped at GM's Milford Proving Grounds. It seems The Beast is undergoing some high-speed tests, though high-speed here is relative. Those Goodyears are only rated for 70 miles per hour or so, and we doubt the big 8.1-liter gasoline-fueled V8 engine is geared to push the President much faster than that, anyway. Related Video:
