2020 Cadillac CT5 debuts at N.Y. Auto Show as a proper sport sedan

The 2019 Cadillac CT5 is here, and it's not a tweener sedan. After having done battle with the luxury sedan world through cars that were either too large or too small, Cadillac is using the CT5 to take direct aim at the BMW 3 Series, Audi A4, Alfa Romeo Giulia and Mercedes C-Class. Specifically, the CT5 replaces the CTS, but takes on vehicles one class smaller than what the CTS did. So, let's take a look at what Cadillac is bringing to the table. To begin, GM knows it has a winner on its hands with the Alpha platform used on the CTS and ATS and the Camaro, so engineers adapted it to the CT5. This seems like a great start, because we all happen to love the driving dynamics from vehicles on this chassis. The wheelbase is a couple inches longer than the CTS, but the CT5 is a couple inches shorter in overall length. As a result, the wheels get pushed toward the corners of the car, leaving the CT5 with relatively short overhangs in the front and rear. It looks different than both of the to-be-discontinued Cadillac sedans, but we wouldn't call it revolutionary. The rear end isn't quite a "sportback," but it's a "faster" shape, eschewing a traditional sedan's long decklid for a sloping-roof look instead. This shape does come at the expense of rear seat headroom, but we'll dive into the interior later. We got a little preview of the powertrain setup before this official reveal, but details were scarce. The base engine is the recently new 2.0-liter turbo four-cylinder found in the Cadillac XT4. Just as it did in that vehicle, this engine makes 237 horsepower and 258 pound-feet of torque. While it might be down on power compared to the old 2.0-liter in the ATS (272 horsepower and 295 pound-feet) we found it to be incredibly smooth, refined and not lacking in thrust compared to the old unit. We're sure the four-pot will offer sufficient power for the CT5, but the 3.0-liter twin-turbo V6 is lying in wait. This engine makes 335 horsepower and 400 pound-feet of torque. Both engines are paired to a 10-speed automatic transmission and can be had in rear-wheel drive or all-wheel drive in every configuration. So yes, you can get the V6 with rear-wheel drive, thankfully. Cylinder deactivation is also equipped to both these power units — the four-banger is able to run on two cylinders, while the V6 drops to four. Cadillac was entirely transparent about its new pumped-in engine sound strategy, too.

Cadillac mulling CTS Coupe successor after all

The 2014 Cadillac CTS made a big splash last week at the New York Auto Show, but now that we've seen the sedan, we can start to wonder about whether coupe and wagon versions are in the cards. According to Edmunds, Cadillac is at least considering bringing back the CTS Coupe for a second generation, which seems like an even better chance since the brand's global marketing director, Jim Vurpillat, was quoted as saying that the car was the top-selling luxury coupe in the industry.
Of course, this goes against reports we heard last year that Caddy's coupe and wagon would live on just not under the CTS name, but the interview with Vurpillat has us hopeful for a next-generation CTS Coupe. If it does come to fruition, we would expect the new two-door to have a largely unique exterior design like the current CTS Coupe, to echo that of intended rivals like the Mercedes-Benz E-Class Coupe and even the high-dollar BMW 6 Series.

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.
