How the demise of Lincoln's Town Car has kick-started a limo revolution

The deaths of the Ford Crown Victoria and the Lincoln Town Car have meant overhauls of three high-profile American fleets: police, taxi and livery car. Just as police fleets are more open to considering other options and a Nissan van is the new face of the NYC taxi, livery car companies are looking at replacements for the Town Car beyond The Blue Oval. Ford, via Lincoln, has made an MKT Town Car (pictured), but an article in the Detroit News claims "it has failed to win over most of the big limousine companies." The upstarts trying to move in include livery and limo editions of the Cadillac XTS, and livery specifications of the Toyota Avalon and Chrysler 300.
Each of those challengers, however, faces challenges. The Town Car was a workhorse, American, rear-wheel-drive sedan with plenty of rear legroom. Cadillac has been in the livery space before but with decontented models that were about selling the brand, not its luxury. It is taking the opposite approach with the XTS, pointing out that its livery edition is "contented in the upper half of the XTS range." Still, the CEO of Michigan's largest livery company says "it's quite a bit smaller than what we're used to," and he also prefers rear-wheel drive.
The Chrysler 300 is rear-wheel drive, and American, which matters to some companies, but Chrysler hasn't yet revealed the livery package for it. The livery Avalon marks Toyota's first time getting into that business in the US, a natural step after having done so well with taxi clients and with the Town Car out of the way. Still, the livery client is a different to taxi buyers, so the Avalon could face other soft-touch hurdles.

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.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.
