2020 Cadillac CT4 revealed in non-V form

We got our first look at the 2020 Cadillac CT4 when its V variant made its debut a few months ago. Now the company is officially showing off the regular CT4 luxury sport sedans. They actually don't look all that different from the V, though - especially the CT4 Sport trim. The Luxury and Premium Luxury trims are distinguished by less aggressive ground effects and a grille studded with chrome pieces shaped like the Cadillac logo. The interior is similar, too, complete with an 8-inch touchscreen. Super Cruise will be made available on the CT4 later in 2020, including on the V model. Really, the big news is the powertrain as V6 engines have been dropped entirely from Cadillac's compact sedan. The base CT4 engine available in Sport or Luxury trim cars is a turbocharged 2.0-liter four-cylinder making 237 horsepower and 258 pound-feet of torque. Coupled to either rear- or all-wheel drive, it features cylinder deactivation and an eight-speed automatic transmission. Unlike in the old ATS, a manual transmission is not available. One notable mechanical difference between trims is the Sport trim gets standard Brembo brakes. Moving up from the 2.0-liter engine is the turbocharged 2.7-liter four-cylinder introduced on the CT4-V. Available on the Premium Luxury trims, its output is downgraded to 309 hp and 348 lb-ft of torque from the CT4-V's output of 325 hp and 380 lb-ft. It too has cylinder deactivation and can be had with either rear- or all-wheel drive. The only transmission offered is a 10-speed automatic. The V model also gets Brembo brake upgrades, and with rear-wheel drive includes Cadillac's magnetically controlled adaptive suspension. Cadillac will start taking orders for the CT4 later this year, but pricing has not been announced yet.

Next Cadillac Escalade's interior spied for the first time

Update: Now that new spy photos of another large GM SUV have surfaced, we believe these shots show us a GMC Yukon interior, not a Cadillac Escalade. You can see the new spy shots here that depict a much more upscale vehicle interior compared to the fuzzy center stack shown in the shots of the Yukon. The new Cadillac Escalade has a lot of work to do in order to properly compete with Lincoln's wonderfully luxurious Navigator. These interior spy photos are our first look at what Cadillac is working with on the inside of its new luxury truck. We won't make final judgements, as this vehicle is still a prototype and subject to change. However, a few key bits are noticeable from the fuzzy photos. As expected, Cadillac's CUE infotainment and center stack is nowhere to be seen. Replacing it is a new interior design language, with a tablet-like screen that seems to rise out of the sloped stack on top. Below the screen is a strip of stitched leather and a couple prominently placed air vents. To the left of this area is what appears to be a push-button gear shifting system, replacing the column-mounted shifter currently in use. Below all that on a lower level of the center stack are all the climate controls, along with what look like physical buttons for what could be audio-related controls. Does it look as luxurious as the Lincoln? Not with all the coverings and shrouding it doesn't, which means we'll have to wait until we get the full picture. One thing that's clear is that the interior design is definitely going to be wildly different than the current Escalade. That center stack flows downward as one sloping piece into the high and bulky center console area. This design looks like it brings the center console further downward, and also uses a multi-tiered look. It's tough to read what's on the screen, but the software looks like the same stuff we got a preview of on the new Cadillac CT5 and CT4 sedans. As for the exterior shots, there's almost nothing that we haven't already gotten a taste of in previous spy photos. The independent rear suspension is a go, as are what appear to be massive headlight and LED DRL fixtures. If you look through the wrapping, you can make out how far up and down the lighting fixtures stretch ... or perhaps they're separate units altogether. It's tough to tell at this point.

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.
