2014 Cadillac CTS

Fixated By Europeans, GM Ensures The Third Time Is A Charm
Few things are better for consumers than competition raising the bar. And no campaign seems fiercer than the one currently underway in the midsize sport-sedan segment now that Cadillac has introduced its all-new 2014 CTS to go head-to-head against the benchmark Audi A6, BMW 5 Series and Mercedes-Benz E-Class.
While the CTS has been on the market for slightly more than a decade, up until this third-generation, Cadillac hasn't truly had the proper high-performance rear-wheel-drive architecture to build a genuine world-class fighter, both inside and out. And now that the American automaker has successfully mirrored Audi, BMW and Mercedes in overall vehicle size, engine output and cabin appointments, the first shots have been fired.

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.

2019 Cadillac XT4 interior has actual buttons, no more touch-sensitive panel

Cadillac makes some highly stylish cars that are excellent to drive. In the realm of infotainment, there was room for improvement. The CUE infotainment system is infamous for being complex and annoying. One particular sore point was the touch-sensitive panels used for basic functions and their unrefined, "haptic feedback" clunk. Thankfully, spy photos show that Cadillac is changing tack both with buttons and infotainment controls in general. As seen above, there don't appear to be any capacitive buttons in sight. Instead, the XT4 has the "piano-key" buttons that are in vogue now. The most prominent are metal-finish buttons that control climate settings indicated by corresponding symbols above the buttons. Below that are additional buttons for seat controls and at least one safety feature, the parking warning. These should be vastly easier to manipulate than tapping and hoping you've engaged the correct function. This doesn't mean there won't be any touch-sensitive controls available, but they've at least been minimized. Other physical controls we spotted are down on the center console near the shifter. It looks as though the CT6's odd touchpad won't be making an appearance in the XT4 as there seems to be a more conventional knob instead. If it's indeed for the infotainment system, it would be a redundant controller as the upper screen's home button and fingerprints would indicate it's very much touch-operated. Like other Cadillacs and GM products in general, it's safe to say that Apple CarPlay and Android Auto will be available and possibly standard. There are a couple other interesting additions besides the physical controls. There's a Near Field Communications (NFC) logo embossed in the dashboard, indicating the car will support NFC pairing of phones. The XT4 also dispatches the more traditional mechanical shifter for a more modern monostable joystick like the found in some Buicks, but with a different shape. We're currently expecting the XT4 to be revealed late in 2018. It will be based on the Chevy Malibu platform, it'll probably stick with turbocharged four-cylinder power, and offer front- and all-wheel drive.
