2014 Chevrolet Impala [w/video]

Can A Fleet Queen Become a Fullsize King?
On paper, the Chevrolet Impala is a pretty strong seller, posting annual sales that have hovered right around 170,000 units for the last two years, but it only takes one trip to practically any rental car agency to discover where the majority of those sales have come from. In fact, General Motors told Autoblog that a full 70 percent of Impala sales last year went to fleet companies for things like rental cars and government vehicles. Logic tells us that this is neither good for resale values nor name equity, so Chevrolet is getting ready to roll out an all-new Impala with improved comfort, styling and technology, hoping to turn the tables on its retail-to-fleet ratio.
Chevrolet's sedans have come on quite strong in the last few months with the introduction of the Cruze diesel and the SS sedan, but while these will likely be low-volume sellers, there's more pressure for the new Impala to perform well as GM looks to slash fleet sales and compete with the wide variety of full-size sub-luxury sedans. Riding on a platform shared with the Buick LaCrosse and Cadillac XTS, the 2014 Impala will compete against the Hyundai Azera, Ford Taurus and Toyota Avalon on the more traditional side, while also looking to take a bite out of somewhat sportier models like the Chrysler 300/Dodge Charger twins and the Nissan Maxima. We headed to sunny San Diego to see if this totally new Impala can stand on its own without the assistance of fleet companies and rental agencies. [w/video

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.

2016 Camaro gets most revealing tease yet

Chevrolet started its long teaser campaign for the 2016 Camaro by just revealing the exhaust manifold and front frame, but as time has passed the company has slowly unveiled more. In the latest glimpse ahead of the pony car's May 16 debut, we're actually getting to see the model's profile completely undisguised. As suggested by the recent tease of the rear and hood, the 2016 Camaro wears a sharper, more angular design than the current model. This is especially the case when you look at the taut lines making up the rear. Chevy claims that the new shape underwent 350 hours of wind tunnel tests to be able to generate left lift, improve cooling and reduce wind noise in the cabin. A smooth underbody pan is among the aerodynamic tweaks, and it runs from underneath the front grille to the center of the Camaro. Chevy asserts that all of the changes at the front help reduce lift by 30 percent. Related VIdeo: 2016 Camaro is all about the Aero Total aerodynamic lift improved by 30 percent for improved stability 2015-05-11 DETROIT – After 350 hours of wind tunnel testing – often 24 hours a day – the new Camaro will slip more easily through the wind, and drivers of the Camaro SS will experience a marked improvement in reduced aerodynamic lift. These changes illustrate the lengths the aerodynamics team went to for improved performance, stability, cooling and lower wind noise intrusion "The importance of aerodynamics increases exponentially as we increase vehicle performance," said Kirk Bennion, Exterior Design manager. "As engine output increases, we need more engine cooling. As acceleration and top speeds climb, we need to reduce lift for better high-speed stability. However, we cannot make any changes at the expense of increasing drag, which can hurt fuel economy. "To balance these different aerodynamic targets, we tested literally hundreds of changes on the new Camaro, millimeters at a time." For example, the initial design called for the lower grille bars to be set at a 20-degree angle to the horizon. However, after meticulous testing, the team improved engine-cooling airflow by 1 percent by shifting the angle to 13 degrees – a change that achieved the airflow target while maintaining the original grille design. And rather than a traditional front air dam to reduce aerodynamic lift, the team developed a flush belly pan that stretches from the front grille to the center of the vehicle.
