Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

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.

GM cancels CES date, possible Cadillac EV crossover unveiling

General Motors is bailing on CES 2020, the big annual consumer technology showcase in Las Vegas, after its plans to showcase an autonomous, electric vehicle were derailed by the 40-day UAW strike this fall. New evidence suggests that vehicle may have been Cadillac’s upcoming EV crossover. MotorTrend got GM to confirm that it was pulling out of CES, which takes place in January, though CEO Mary Barra in an interview said only that the vehicle they had planned to unveil was electric and featured autonomous technology — two key areas where the automaker plans to focus in the future. The automaker said the model simply wasnÂ’t ready. But MT said it then received an invitation from Cruise, GMÂ’s self-driving vehicle subsidiary, to an event later in January in San Francisco. That suggests the automaker could have been planning a different vehicle to show at CES than its self-driving Cruise AV “robotaxi,” which famously features no steering wheel or pedals. Cadillac showed off a digital rendering of a forthcoming unnamed electric crossover in Detroit in January, saying only that it would be available in both two- and all-wheel drive and sold globally. GM has said Cadillac will be its lead brand as GM delves into EV technology. The speculation is that the crossover will also feature CadillacÂ’s Super Cruise semi-autonomous highway driving technology. Whatever the vehicle was, or is, Barra said itÂ’ll be ready for viewing in the first half of 2020. GM has been developing the Chevrolet Bolt-based Cruise AV, a fully autonomous car, alongside its Cruise self-driving technology subsidiary, and building them at Orion Assembly plant near Detroit. It had once planned to debut a fleet of ride-hailing Cruise AV robot axis by the end of this year but realized the timeline was not realistic. Testing of the robot axis continues in San Francisco, Phoenix and Michigan. As for timing on a new timeline for fleets of Cruise AVs to take over the streets, Barra wouldnÂ’t show her hand. “We see a line of sight but weÂ’re not going to put another date out there,” she told MT, adding it was more important to “gain customer trust and usage.” As for Cadillac, any new reveal would likely come after the all-new Escalade SUV in February and amid a product blitz that will see it introduce a new or redesigned model roughly every six months through 2021.
