2021 Cadillac CT5-V makes a few changes for its second year

An order guide for the 2021 Cadillac CT5-V reveals a number of small changes to the sedan's formula going into its second year on the market. Starting with the superficial, the $1,225 Red Obsession Tintcoat exterior color and the $625 CT5-V-exclusive Royal Spice Metallic depart after this model year. They'll be replaced by Infrared Tintcoat and another color exclusive to this model called Rift Metallic. Since all but Summit White and Black Raven are cost-option Premium hues, the new colors should be expected to add to the price. Materially, the interior finish spiffs up with better-quality Modena leather stitched around the steering wheel rim, and Senza leather on the wheel center.    Next year, wireless Android Auto and Apple CarPlay will come standard, a promotion over the current wired systems. Getting around the infotainment screens will be easier thanks to a rotary dial that can slide laterally to choose menu items. The digital radio moves up to SiriusXM 360L, providing 4G streaming functionality. For the younger drivers in the family, the Teen Driver System will include Buckle to Drive. On the current CT5-V, the Navigation and Bose Premium Audio Package adds the Cadillac user experience with navigation, a 15-speaker Bose audio system, and an eight-inch configurable Driver Information Center display between the dash cluster gauges. For 2021, the eight-inch display is discontinued, so the package gains wireless phone charging. A new Technology Package replaces the current eight-inch DIC with a 12-inch configurable digital gauge cluster that sprouts a head-up display taken from the Driver Awareness Plus Package. The Technology Package will be included in the Platinum Package that right now costs $6,290, and that automatically adds the $4,190 Premium Package and $1,950 Driver Assist and Advanced Security Package. Based on current prices, the order guide indicates the Platinum Package will cost at least $12,430. Because of such bundling, the same package on the 2020 CT5-V 'roids up the MSRP by $13,730. Without ordering the Platinum Package, both the Navigation and Technology Packages will require the Premium Package.

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.

2017 GMC Canyon steals Cadillac's V6 for a little more power

GMC is fortifying the Canyon with a new powertrain and two new trim levels for 2017. GMC will give the Canyon the 3.6-liter V6 found in the Cadillac ATS, CTS, CT6, and XT5 crossover. The engine will be matched to an eight-speed automatic transmission, which also can be found on Cadillacs, the new 2017 Colorado, and other General Motors vehicles. The new engine comes with variable valve timing, improved direct injection, and Active Fuel Management, which is a form of cylinder deactivation that shuts off two cylinders to increase fuel efficiency and performance. Power is up from 305 to 308 horsepower, while torque increases from 269 to 275 pound-feet of torque compared to the old 3.6-liter V6. With the new transmission, the Canyon benefits from a higher first gear ratio, which should help drivers get off the line more easily when towing large cargo, and lower overdrive ratios for improved fuel efficiency. The 2016 model had a six-speed automatic. The Colorado also gets the eight-speed transmission for '17. GMC previously announced the All Terrain X and Denali models. The All Terrain X trim is offered on the SLE model and comes with the new 3.6-liter V6 engine or the 2.8-liter Duramax turbo-diesel. The All Terrain X gets Goodyear Wrangler DuraTrac P225/65R17 all-terrain tires, a body-color grille surround and matching rear step bumper, bespoke 17-inch aluminum wheels, and a spray-on bedliner. The truck also is fortified with Hill Descent Control and an off-road suspension. The Denali carries the flag as the most luxurious Canyon model and gets a Bose seven-speaker audio system, more chrome, and interior upgrades. In addition to the new models and the powertrain, the 2017 Canyon will be offered with new colors – Dark Slate Metallic, Mineral Metallic, and Red Quartz Metallic – a new IntelliLink radio with a seven-inch touchscreen, a heated steering wheel as an optional extra, and Standard Teen Driver Mode. The 2017 Canyon, with all of its changes, will be available in the fourth quarter of the year.
