2016 Cadillac CT6 cuts weight with aluminum-intensive chassis

Big Cadillacs used to be the definition of automotive access, with heavy steel bodies that seemed to take up acres of space. Cadillac is hoping to change that with its latest flagship, the 2016 CT6.

While the car itself won’t be revealed until the 2015 New York Auto Show in a couple of weeks, General Motors couldn’t wait to show off its aluminum-intensive skeleton.

Cadillac says significant amounts of aluminum and other lightweight materials in the chassis save 198 pounds over a comparable all-steel chassis.

Roughly 64 percent of the CT6 body is aluminum, including all exterior body panels. High-strength steel is used in other areas to maximize rigidity for crash protection and to give the car a solid feel.

That includes steel “close-out panels” on the underside of the chassis, which Cadillac says yield a “bank-vault quiet” cabin. It claims this approach saves weight over a design using more aluminum, which would require extra sound-deadening material to get the same results.

Based on the CT6’s brief appearances in Cadillac ads, it looks like the bodywork clothing that lightened chassis will look like an upsized version of designers’ previous work on the ATS and CTS.

A V8 engine seems obligatory to match the CT6’s full-size luxury sedan rivals, but there have also been rumors that Caddy’s new flagship will be offered as a plug-in hybrid, taking the efficiency theme a step further.

The 2016 Cadillac CT6 will be unveiled March 31 at the New York Auto Show, and go into production later this year. We’ll have all of the details live from the Big Apple.

Never mind slowing sales, 57% of drivers will likely have an EV in 10 years

Sales of electric vehicles (EVs) have slowed globally over the past few years. But should EV makers cater more to the mainstream, it’s likely that 57% of drivers will have an EV in 10 years, consulting firm Accenture says.

Last year, nearly 14 million EVs were sold globally, representing a 35% year-on-year increase. But it was much slower than the 55% sales growth recorded in 2022 and the 121% growth in 2021.

I spent a week with an EV and it completely changed my mind about them
The Cupra Born VZ seen from the front.

After spending a week with an electric car as my main vehicle, opinions I’d formed about them prior to spending so much time with one have changed — and some quite dramatically.

I learned that while I now know I could easily live with one, which I wasn’t sure was the case before, I also found out that I still wouldn’t want to, but for a very different reason than I expected.
Quiet and effortless

Domestic manufacturers of EVs and their components, such as batteries, have received tax incentives that have driven job opportunities in states like Ohio, Kentucky, Michigan, and Georgia, the group says.
