New Corvette Feature Keeps An Eye On Valets

Face it. If you own a luxury or sports car, whenever you hand the keys to a valet, you imagine the car going on a high-speed joyride like the Ferrari in the 1980s cult movie "Ferris Bueller's Day Off." Now, General Motors has an option on the 2015 Chevrolet Corvette that takes those worries away. The latest version of the sports car, due out in September, has a feature that records where the car goes with a camera mounted in the windshield trim. It also captures audio in the cabin as well as speed, engine revolutions per minute, gear position and G-force. That all helps the car tattle on any valet who doesn't take a slow, direct route to a parking space. GM says it's the most extensive attempt by an automaker to thwart valet joyriders, although it's not the first. The automotive website Edmunds.com says Hyundai and Mercedes offer "geofencing," a feature that sets a perimeter and then notifies the owner's smart phone if a car goes beyond it. Chrysler has a valet mode that caps engine speed and horsepower, while Audi lets owners limit engine speed for valets. With the Corvette, once the owner activates the feature with a four-digit code, the touch screen tells the driver it's in Valet Mode. But it doesn't warn the valet that he's being recorded. The feature also locks the glove box and a storage compartment in the dashboard and shuts down the infotainment system. Valet Mode started off as a performance data recorder for those who take their Corvettes on the racetrack. GM engineers quickly figured out that it had more uses. "Think of it as a baby monitor for your car," Corvette Product Manager Harlan Charles said in a statement. "Anyone who has felt apprehension about handing over their keys will appreciate the peace of mind of knowing exactly what happened while their baby was out of sight." Data and video from the valet mode can be viewed instantly by the owner on the car's 8-inch color screen when the car is parked, or it can be downloaded to a computer. The system could go into more mainstream models if feedback is good on the Corvette, GM spokesman Monte Doran said. The feature is paired with a navigation system and costs $1,795. A 2015 Corvette starts at just under $54,000. Chevrolet Technology Gadgets

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Both Android Auto and Apple CarPlay slated for Chevrolet lineup

Long awaited, the race among automakers to keep drivers connected to their smartphones has officially entered a new era. Hyundai said Tuesday it would be the first manufacturer to put Google's Android Auto into a production car, the 2015 Hyundai Sonata sedan. Not to be outdone, General Motors said today it'd offer both Android Auto and Apple's CarPlay on several Chevrolet models set to hit dealerships this summer. By giving car buyers the choice between these rival phone-projection systems, Chevrolet hopes to quell concerns from prospective customers worried about the compatibility of their smartphones and vehicles. "It's about providing choice," said Alicia Boler-Davis, GM's senior vice president for global connected car consumer experience. "No two customers are alike, and we cannot expect a single solution that works for every driver in every situation." Across the industry, automakers are rushing to add both to their cars as a growing base of customers seek an array of connected features. Estimates from automotive technology research firm SBD indicate smartphone-integrated content is available in 36 percent of current vehicles, and the company expects that penetration rate will grow to 84 percent by 2025. For Chevrolet, the systems will be available on select 2016 iterations of the Cruze, Camaro, Volt, Spark and Malibu as early as next month, and appear on 14 Chevy models overall for the 2016 model year. They're available on all trim levels, but they only work with the company's MyLink infotainment package installed in the cars, and the first to hit showrooms will only work on the seven-inch touchscreen models. "CarPlay and Android Auto, these are things that are addressable to the broad market, and I think it makes a lot of sense for GM to put it into Chevys first," IHS Automotive senior analyst Mark Boyadjis said. Via physical connections, both Apple CarPlay and Android Auto allow users access to smartphone features like turn-by-turn directions, phone calls, voice-to-text messages and music streaming. Interfaces are similar to the ones found on the respective smartphones, but on the dashboard, they're redesigned for a simpler, in-car experience. Fonts are larger, for example, and easier to press on a touchscreen. CarPlay relies heavily on Siri so that drivers spend more time staring at the road instead of their touchscreen. That sounds good, at least in theory.
