2016 Cadillac ELR gets more power, $9,000 price drop

Cadillac has announced a series of updates to the ELR for 2016 that promises to make the plug-in hybrid luxury coupe a more desirable proposition. Perhaps chief among them is a price drop of $9,005 compared to the slow-selling 2014 model. The news follows an announcement yesterday that the Chevy Spark would get a $1,500 price drop. Cadillac is quoting a net price for the updated ELR at $58,495, which is obviously substantially less than the $75k it was asking for the previous version. But it's important to note that the new price is listed after US federal tax credits. The 2014 model came in at $67,500 after the full $7,500 tax credit, so math tells us that Cadillac has slashed the price on the 2016 ELR rather dramatically by about nine grand with a new MSRP of $65,995. One big upgrade on the performance front is a 25-percent boost in output from the hybrid powertrain that marries a pair of electric motors to a 1.4-liter inline-four gasoline-burning generator. The increase is said to be enough to drop 1.5 seconds off the 0-60 time, now quoted at 6.4 seconds. It'll travel for up to 39 miles on electric mode alone, but with the generator spooled up will go up to 330 miles before needing to stop. The engine management software has also been updated and the regenerative braking system reconfigured as well, but GM's luxury division didn't stop at the powertrain, fitting the 2016 ELR with a raft of other enhancements. Visually there's a new grille with the marque's latest emblem embedded. The suspension has been stiffened, the steering recalibrated and the brakes optimized for better feel. Cadillac is also throwing in the previously optional Driver Assistance package of active safety systems as standard, with adaptive cruise control available as an option. And the infotainment system comes with OnStar, 4G LTE connectivity and on-board Wi-Fi. There's even a Performance Package available with 20-inch performance tires offering 10-percent better lateral grip, four-piston Brembo brake calipers up front to help reducing stopping distances by 12 percent, recalibrated dampers and steering and a thicker-rimmed steering wheel. Because of the higher rolling resistance tires, however, the Performance Package kills four miles off of the electric driving range.

GM's latest production delays: Colorado/Canyon, Cadillac CT4/CT5, Camaro

DETROIT — General Motors Co extended production cuts in North America on Wednesday due to a worldwide semiconductor chip shortage that has impacted the auto sector. The U.S. automaker said its Wentzville, Missouri, assembly plant would be idled during the weeks beginning March 29 and April 5. It will extend down time at its plant in Lansing, Michigan, which has been idled since March 15, by two weeks. The action was factored into GM's prior forecast that it could shave up to $2 billion off this year's profit, spokesman David Barnas said. GM did not disclose how much volume would be lost by the move, but said it intended to make up as much lost production as possible later in the year. The chip shortage came as North American auto plants were shut for two months during the COVID-19 pandemic last year and chip orders were canceled, and as demand surged from the consumer electronics industry as people worked from home and played video games. That's now left carmakers competing for chips. Semiconductors are used extensively in cars, including to monitor engine performance, manage functions for everything from steering to automatic windows, and in sensors used in parking and entertainment systems. Vehicles affected by the GM production cuts include the mid-sized pickup trucks, the Chevrolet Colorado and GMC Canyon in Missouri, and the Cadillac CT4 and CT5 and Chevy Camaro cars in Michigan. Meanwhile, GM said its San Luis Potosi, Mexico, assembly plant, idled since Feb. 8, will resume production with two shifts beginning the week of April 5. Last week, GM said it was building certain 2021 light-duty full-size pickups without a fuel management module, hurting their fuel economy performance by one mile per gallon. Exacerbating the shortage is a recent fire at a Renesas Electronics chip plant in Japan. Barnas said GM was assessing the impact of the fire.  

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.
