2014 Chevy Cruze Diesel destined for Chicago debut

It's been a little over a year and a half since General Motors first confirmed plans to offer a diesel-powered Chevrolet Cruze here in the United States, and we've now learned that the oil-burning compact will debut under the lights of the Chicago Auto Show in February. According to GM Authority, the Cruze Eco-D will be introduced as part of the entire 2014 model year Cruze range, set to go on sale in the second quarter of this year.
Earlier reports have indicated that the diesel Cruze will be able to achieve fuel economy numbers in the range of 50 miles per gallon. For comparison, the similarly sized Volkswagen Jetta TDI is rated at 30/42 mpg city/highway, but as we found out in our long-term test of the 2011 model, hitting 50 mpg was a piece of cake.
Official specifications will be released at the time of the 2014 Cruze's unveiling, though reports have stated that the sedan will be powered by a reworked version of the 2.0-liter turbo-diesel inline-four found in the Holden Cruze CDX overseas. In that application, the four-pot oil-burner produces 160 horsepower and 265 pound-feet of torque - increases of 20 hp and 29 lb-ft over the 2.0-liter engine used in VW's Jetta TDI.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

2015 Chevy Volt will be available with 4G LTE

General Motors teased consumers two years ago when it showed off a Chevrolet Volt decked out with 4G LTE connectivity. More details were finally unveiled this month at the Consumer Electronics Show in Las Vegas: the 2015 Chevy Volt will have a 4G LTE option and will offer consumers an as-yet-unpriced option with much faster wireless internet connection and more smartphone apps. GM's OnStar has teamed up with AT&T to come up with several mobile apps alongside the roadside assistance. The Volt joins the 2015 Corvette, Impala and Malibuz models that will debut with a 4G LTE option this year. The first four 4G ChevroLTE models will be released this summer and will be joined by the Spark (EV and gas versions), Equinox, Silverado and Silverado HD. GM has yet to announce whether any Cadillac or Buick models will get the 4G option. Chevrolet Accelerates to 4G LTE Speeds in 2014 Bowtie brand models in U.S. and Canada to get OnStar 4G LTE by summer LAS VEGAS – Starting this summer, Chevrolet will have some of the fastest vehicles on the roads, and that has nothing to do with horsepower. Chevrolet drivers will be enjoying high-speed data - made possible by a new OnStar 4G LTE connection in the vehicle, running on AT&T's network, the nation's fastest and most reliable 4G LTE network. Chevrolet today announced at the Consumer Electronics Show that the 2015 Chevrolet Corvette, Impala, Malibu, and Volt would be the first General Motors' vehicles to come optionally equipped with OnStar 4G LTE. They will be followed by the Equinox, Silverado, Silverado HD, Spark and Spark EV. In the Canadian market, OnStar with 4G LTE will be introduced on the Chevrolet Trax as well. The majority of the 2015 Chevrolet lineup in the U.S and Canada will have a 4G LTE connection built-in at vehicle launch. More models will be announced later this year. "Chevrolet is expected to implement the broadest deployment of 4G LTE in the automotive industry," said Alan Batey, senior vice president of Global Chevrolet. "The fact that OnStar with 4G LTE will be available in models that range from the Chevrolet Spark to the Silverado to the Corvette, is indicative of our broad commitment to deliver more value and convenience through smart technology applications.
