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.

Dodge Dart falls short of Consumer Reports Recommended, Caddy XTS and Lincoln MKS, too

The Dodge Dart, Cadillac XTS and Lincoln MKS all failed to earn a "Recommended" rating from Consumer Reports. When it came to the compact Dart, the organization's testers thought the vehicle offered a quiet cabin, solid-feeling chassis and nimble suspension, but the new model ultimately fell short of the coveted rating due to powertrain issues. The institute's reviewers found the base 2.0-liter four-cylinder engine to be underpowered and noted "drivability issues" when the available turbocharged 1.4-liter four was paired with the optional dual-clutch transmission (some of our editors disliked it paired with the six-speed manual). CR also dinged the latter powerplant for sounding "raspy." For what it's worth, we think the forced-induction engine offers an excellent and playful exhaust note, but that's just us.
As for the XTS, CR lauded the car for its luxurious cabin, but the vehicle's experience was dulled by its finicky CUE infotainment interface. Overall, the big Cadillac scored much higher than its cross-town rival from Lincoln. While testers found the American luxury sedan to offer a quiet ride and quality fit and finish, they felt the MKS delivered a "cramped driving position, ungainly handling, uncomposed ride, and limited visibility." Ouch. At the end of the day, both cars fell short of rivals from Japan, Germany and Korea. Check out the full press release below with more details, along with CR's musings on the Chevrolet Spark and Lexus ES.

2023 Cadillac Lyriq production model revealed with range, power, price

We got our first look at the Cadillac Lyriq's design last August, and now the company is revealing the official production version of the electric crossover. The good news is that it looks almost identical to the preproduction version no matter where you look, inside or outside the car. It has the same long hood, low roof, creased body work, illuminated grille and groovy taillights. The interior retains the 33-inch instrument and infotainment screen and wood and metal trim. Only detail changes to things like the camera in the grille and the reworked control knob in the center console distinguish it from the concept. So if it basically looks the same, what's new here? Well, we finally have specifics on all the stuff that powers the concept-car body. At launch, the Lyriq will only be offered with a single motor and rear-wheel drive. The motor makes 340 horsepower and 325 pound-feet of torque funneled through a single-speed transmission. Supplying the motor with juice is a 100-kWh battery, though Cadillac didn't specify if that's the usable capacity or gross capacity. Cadillac estimates that the battery will provide more than 300 miles of range on a single charge. The initial models will be equipped with on-board charging equipment that can handle 19.2-kW Level 2 charging and 190-kW DC fast charging. The former can add 52 miles of range in an hour, and the latter can add 76 miles of range in 10 minutes and 195 miles in half an hour. Cadillac has made no mention of an 800-volt extra-fast DC charging system like in the GMC Hummer EV. There's a chance a system like that could be offered later, just like the forthcoming all-wheel-drive Lyriq variant. The Lyriq rides on multi-link independent suspension at all four corners, using "passive-plus" shocks, so it won't be adaptive or use GM's fancy magnetic suspension, at least at launch. Braking is provided by large 17-inch rotors at the front and 18-inch units at the back, welcome additions for the 5,610-pound crossover. Cadillac also gave us some basics on what equipment will be offered with the first run of Lyriqs. Only two colors, a silver and a black, will be available to begin with, and another silver will come a tad later. We imagine more colors will be offered on later Lyriq models. The interior comes in gray or black. Twenty-inch wheels are standard with 22-inch examples available as an option.
