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 CT6 uses aluminum to save 200 pounds

In Cadillac's recently launched ad campaign, the luxury brand's tagline is "Dare Greatly," and the two words suggest a brand willing to take big swings, even if they don't always connect. From what the company is promising, the forthcoming CT6 seems like an embodiment of that new motto. With an eventual range of turbocharged engines, reportedly including a turbo V8, a possible plug-in hybrid and streaming rearview mirror, the sedan is certainly pitched as tech showcase. Of course, extensive use of aluminum is practically mandatory to play in the luxury field these days, and Caddy is proving its latest creation can do that too. Despite the weighty appearance of the sedan's squared-off exterior, 64 percent of the CT6 is aluminum, including the entire exterior. Caddy claims that using so much of the lightweight metal sheds 198 pounds off the scales compared to using conventional steel. There still is some steel in the CT6; although it's predominately the high-strength variety. The engineers use the heavier metal for portions around the cabin and B-pillar for added safety. Cadillac also claims using steel "close-out panels" on lower portions of the sedan make the cabin quieter without needing as much sound deadening. The buildup to the CT6's public unveiling has been a long time coming after Cadillac pinned the flagship (for now) sedan's debut at the New York Auto Show nearly a year ago. When the sheet finally comes off on March 31, we get the first good idea about just how great Caddy's latest act of daring really is. Cadillac CT6 Elevates the Science of Mass Efficiency 2015-03-13 Technology DETROIT – Cadillac will use an advanced mixed-material approach for the lightweight body structure of the upcoming CT6 range-topping sedan. The structure is aluminum intensive, but the new Cadillac also includes 13 different materials customized for each area of the car to simultaneously advance driving dynamics, fuel economy and cabin quietness. The CT6 will debut March 31 at the New York International Auto Show and go into production late this year at General Motors' Detroit-Hamtramck assembly plant. "This is the rocket science of automobile construction and manufacturing today," said Cadillac President Johan de Nysschen.

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.
