Volvo and GM team with Amazon for in-car deliveries

Volvo and GM are the first automakers to pair their vehicles with a new service from Amazon that lets owners have their packages delivered inside their cars, without them having to be there. The service will initially be rolled out in 37 U.S. cities at no extra charge to Amazon Prime members with a Volvo On Call or OnStar account, and it works with same-day, two-day and standard shipping. It's intended as an alternative for people who don't want to risk having their package stolen from their front porch or receive deliveries at their workplace, and both automakers say it's an example of how they're embracing innovation as a way to make their customers' lives easier. Volvo released a video (above) showing how the service works. Users download the Amazon Key App (or " Ama-zin," as the narrator pronounces it) and link their Amazon Prime account with their Volvo On Call account — or OnStar, in the case of GM-branded vehicles. Once they register their delivery location in a publicly accessible location, users can select the "In-Car" option at checkout. They get a notification when the delivery is en route and once it's completed and the car is relocked. Volvo has been offering in-car delivery in certain European countries since 2015 through its Volvo On Call platform, which enables services like the ability to send calendar-based navigation destinations directly to the vehicle, find nearby gas stations and help locate the vehicle when you forget where you parked it. Volvo says the platform is now available in roughly 50 countries and covers more than 90 percent of its global sales. The service is compatible with 2015 or newer Volvo, Buick, Cadillac, Chevrolet and GMC vehicles. Volvo says it's available to the majority of Volvo owners, while GM says more than 7 million vehicle owners can qualify. The service is expected to roll out to more cities later.

Cadillac to recall 20,000 SRX models over wheels that could fall off

A potential issue with the lug nuts on 19,871 units of the 2013 Cadillac SRX in the US and Canada has lead to a recall of the luxury crossover. Those lug nuts that have a Teflon topcoat, identified by their bluish tint, could loosen and cause "creaking, rattling or grinding noises or steering vibrations." In the worst case scenario, a wheel could fall off, but there have been no reports of that happening, nor any reports of accidents or injuries due to the issue.
This is the second recall action on the SRX over the last few months. In March, Cadillac recalled 27,000 SRX models over a transmission programming issue. General Motors will begin notifying customers with the potentially faulty parts on June 3, at which time they can take their vehicles to dealers to have the tires rotated and new nuts installed. A further 7,397 SRXs exported from North America also face the recall action.

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.
