2020 Cadillac CT5 loses the fake scoop

Well folks, the inevitable has happened. The 2020 Cadillac CT5 luxury sports sedan prototype has shed its hood scoop. Yes, we're as disappointed as you are that instead of being outrageous and brash, Cadillac is still going to try to be classy, understated and luxurious when it comes to its mainline models. And yes, we're being sarcastic here ... but there's a part of us that would kind of like to see the scoop survive. Anyway, the good news is that the scoop is only one of a few bits of fake bodywork and camouflage that the CT5 has shed. As such, we get our best look yet at the new Cadillac sedan, and it looks pretty good. The grille is very wide and not nearly as tall as the prominent prows of current Cadillacs. It actually doesn't even look as tall as the grille of the Escala concept that inspired the CT5's design. The profile of the CT5 isn't too radically different from existing Caddies, with a long hood and a short trunk. It is still a conventional sedan, though, and not a sedan-like hatchback like the Kia Stinger and Audi A5 Sportback and A7. This is evident by the open trunk lid our spy photographer caught. The taillights also continue to be slim and vertical, though we can't quite tell if they will have a horizontal elements at the bottom like on the XTS and XT4. The car also has very bold and thick angular exhaust tips. We expect the CT5 will go into production in 2019 as a 2020 model, and it will likely take the place of both the CTS and ATS, but not be much smaller than the CTS. It will likely use versions of existing Cadillac engines including the 2.0-liter turbo four-cylinder, naturally aspirated 3.6-liter V6, and twin-turbo 3.0-liter V6. We wouldn't rule out the 4.2-liter twin-turbo V8 for a potential CT5-V in the future. Related Video:

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.

Cadillac logo losing its wreath?

The easily recognizable Cadillac logo dates back to the company's founding in the early 1900s, but over the last 110 years, there has been an on-again, off-again love affair with the wreath surrounding the crest. Cadillac's current badge design has used the wreath since the 1980s, but Automotive News is reporting that GM's luxury division is planning to ditch the laurel wreath for a cleaner-looking logo.
The new logo could make its debut as early as next month on a new concept car that will be revealed at the Pebble Beach Concours d'Elegance, although the report also says that it might be until 2015 before it makes its way to a production car. Even then, it doesn't like anything has been finalized yet, as the article also says that plans could still change.
As Cadillac looks to improve its global presence as a luxury automaker, the report says that a simpler logo could make it easier for designers to incorporate the badge onto the car - either in the grille or above the grille (possibly in a fashion similar to Mercedes-Benz). Head on over to the AN article, which shows the Cadillac logo dating back to its earliest design.
