2020 Cadillac CT5 in New York: 7 questions with the chief engineer

Cadillac revealed the 2020 CT5 at the New York Auto Show, and we decided to sit down and have a chat with chief engineer Mike Bride to learn more about the car. You can read our reveal post here to get the full download, and then read on below to learn a bit more. Cadillac is still rather coy about any performance model to spawn from the CT5, but things appear to be looking up after our conversation that you can read below. Q: What's the driving nature of this car? Should we expect something similar to the CTS and ATS? A: Yes, you can see it's built off the rear-wheel-drive architecture. Our goal was to retain all of that fun-to-drive nature. Direct steering feel, responsive handling. Going forward, we ask how we can continuously improve, and that was really about driving more sophistication in the ride, a much more mannered car that's better for impact harshness and rolling isolation, really provides comfort when you want comfort over tire strips and heaves in the road. Really getting that level of isolation, but not compromising that handling and direct steering feel of the Cadillac sedans we've grown accustomed to. Q: How is this car different from the CTS underneath, and other Alpha platform cars? A: I would say this is a major revision. A lot of new parts, a lot of new part numbers, a significant evolution. In the suspension space, the links are all new, and there's been a lot of work done in isolation, so the bushings and strut mounts are all new. We've evolved the Alpha platform to now get the ride control and road isolation, the comfort aspects of it all. There are a lot of structural improvements like a changed wheelbase, an evolution in rear foot-swing and foot space from the fuel tank area to get in and out of the car better. As we developed this structure, it was about overall structural body stiffness, and impedance at the chassis attachments to really get that level of isolation from road inputs. We try to have a calm floor, a steering wheel that doesn't vibrate, and quiet to the driver's ear. Those were the paths we went after to really drive the structure to the right stiffness requirements, structural integrity, a lot of development into suspension bushings, tuning elements, strut mounts. We have a new damper technology, a ZF damper. It has MVS damper technology. It's a multi-valve system that provides less harshness from an NVH standpoint and a great optimization balance of motion control with ride inputs.

Cadillac Super Cruise, a hands-off review

Cadillac Super Cruise won't let you eat breakfast behind the wheel, climb in the back seat or any of the other stupid human tricks displayed on YouTube by Tesla owners. It even won't allow the car to change lanes on its own, like Tesla Autopilot. But it's a big step on the road to full autonomy, a huge convenience on long-distance road trips and a substantial technological triumph for Cadillac. In the simplest terms, Super Cruise is a lane-centering enhancement to adaptive cruise control (ACC). But Super Cruise is anything but simple. Its technical complexity — hence its long delay after first being unveiled five years ago — belies its straightforward operation and intuitive user interface, which I discovered on an almost 750-mile, 11-hour drive in a 2018 Cadillac CT6 between Dallas and Santa Fe to test the system. LOADS OF LIMITATIONS First, let's dispense with the details and disclaimers. Super Cruise is standard on the 2018 CT6 Platinum and a $5,000 option on other trim levels. Because Super Cruise is supported by OnStar — an OnStar operator will call to find out if first responders need to be sent in a worst-case scenario — a three-year OnStar Super Cruise Package is included with the system. Super Cruise has loads of limitations that are probably more concerning to GM's legal counsel than they were to me during my long drive. Some are no-brainers, such as not for use in construction zones or for driving on the shoulder. But the system can also be stymied by adverse weather, poor visibility and faded lane markings. Super Cruise only works on freeways with on and off ramps and a center divider. ACC and forward collision warning also need to be engaged, and the system's cameras and radar sensors can't be obstructed. To keep drivers from looking away from the road for too long — and to keep the system active — an infrared camera on top of the steering column keeps an electronic eye on the driver's seat. GM has over 100 patents alone on this Driver Attention System, including an algorithm that triangulates the nose, eyes and ears in case the camera can't see through sunglasses to make sure you're not nodding off. In addition to the car's visible sensors, another major component of the system is something you don't see: mapping software. But not the kludgy kind that powers in-dash navigation systems.

Cadillac ATS was almost front-wheel drive

"We were going to do a front-wheel drive Cadillac compact off of Delta because it was going to be less expensive," Doug Parks, General Motors' vice president of global product programs, told the Automotive News during the Detroit Auto Show in January of this year. That sentence, referring to early ATS discussions more than five years ago - a period when the automaker, and the industry, was struggling - reveals that Cadillac's highly acclaimed rear-wheel drive compact sedan almost never happened.
Parks revealed that that automaker actually built a 2.0-liter test mule, on GM's Delta platform (shared with the Chevrolet Cruze and Buick Verano) and tested it in Europe. While the prototype was "pretty darn good," according to Parks, the team realized that in order to compete against Mercedes-Benz and BMW it would have to invest in a new rear-wheel drive platform.
The resulting all-new Alpha platform would eventually underpin the Cadillac ATS, and many would argue that its balanced rear-wheel drive chassis is its single most important attribute. Thankfully, the Alpha's goodness won't stop with the ATS. The upcoming 2014 Cadillac CTS and the future Camaro will also share its architecture, meaning the Cimarron will remain a distant memory.
