GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

2014 Chevrolet Cruze TD fires up its new diesel motor

Ever since General Motors confirmed plans to produce a diesel-powered Cruze back in 2011, we've been eagerly awaiting its arrival. And as part of the 2013 Chicago Auto Show, Chevrolet has pulled back the cover on its oil-burning compact sedan, set to go on sale in the near future with a starting price of $25,695, not including $810 for destination.
The heart and soul of the Cruze TD (that's its official name) is a 2.0-liter turbo-diesel inline four-cylinder engine rated at 148 horsepower and 258 pound-feet of torque, mated solely to a six-speed automatic transmission. The engine also has an overboost function that will increase torque to 280 lb-ft for up to ten seconds. The full brace of official specs haven't been released, but GM tells us that highway fuel economy will come in at 42 miles per gallon. If that number sounds familiar, it's because the Volkswagen Jetta TDI has the exact same rating. Unlike the Jetta, however, the Cruze TD can run on B20 biodiesel, where as the Volkswagen can only accept B5.
Model-specific changes to this 2014 Cruze TD include an aero kit and unique 17-inch alloy wheels. Inside, there's a full leather interior, and Chevrolet will provide two years of complimentary scheduled maintenance, not to mention a 100,000-mile powertrain warranty.

2016 Chevrolet Camaro design teased

Chevrolet just can't seem to help itself from continuing to tease the next-gen Camaro. The pony car gets its official debut at a big event on Detroit's Belle Isle on May 16, but the upcoming model's new exhaust, suspension components, and wheels are already well known. With this latest taste, we're finally getting an official glimpse at what the coupe actually looks like. The 2016 Camaro's shape hasn't completely been a secret, and even Chevy showed it testing while covered in camouflage in March. Still, these shots are a great opportunity to check out some undisguised details for the new model. The styling is supposed to be "more athletic," according to Chevy, and the aluminum hood looks especially good with crisp, straight lines forming the design. "It's a more expressive evolution of the Camaro's iconic character – and one that complements its leaner size and sharper reflexes," GM global design boss Ed Welburn said in a statement. These two photos suggest a more angular, futuristic shape for the upcoming pony car. We're looking forward to seeing it all in a couple weeks. Sculpted Exterior Reflects 2016 Camaro's New Athleticism 2015-04-30 DETROIT – For the all-new 2016 Chevrolet Camaro, the design team set out to create a leaner, more athletic design that complemented the new driving experience. "The Camaro went to the gym and came out with a lithe, more athletic physique for the sixth generation," said Ed Welburn, vice president, GM Global Design. "It's a more expressive evolution of the Camaro's iconic character – and one that complements its leaner size and sharper reflexes." The exterior design vocabulary is defined by complex shapes, which appear to be form-fitted around the mechanical components. Every shape and surface detail is a skilled, artistic collaboration of hand and digital sculpting. Camaro's new design details draw the eye into the design. For example, the new aluminum hood features powerful, smoothly curved sculpted forms accented with sharp creases. As a result, the hood appears to be shrink-wrapped around the engine. Similarly, the new Camaro retains the broad, dramatic rear fenders that became a defining feature of the award-winning Gen 5 Camaro. The design is updated with greater detailing, including a subtle crease running parallel to the fender edge. The effect makes the new Camaro look even lower and wider despite having a slightly smaller footprint than its predecessor.
