Cadillac confirms 420-hp twin-turbo V6 for 2014 CTS [w/videos]

The 2014 CTS will break cover next week at the New York Auto Show, but Cadillac has released a few details of what we can expect to find under the car's hood. As we saw in some spy shots back in January, the biggest news for the midsize Caddy will be a twin-turbocharged V6 producing a whopping 420 horsepower and 430 pound-feet of torque.
This LF3 engine will be paired to a new eight-speed automatic transmission, which will help balance performance and fuel economy. We still don't know how much the 2014 CTS has grown in terms of size and weight, but General Motors says that new sedan will return 17 miles per gallon in the city and 25 mpg highway with the new engine to go with a 0-60 mile per hour time of 4.6 seconds - that means the new CTS will have the fuel economy close to the current base model sedan and acceleration not too far from the current CTS-V. General Motors also confirmed that this twin-turbo V6 will be available in the 2014 XTS this fall.
The next-generation CTS will carry over the 3.6-liter V6 from the current car (likely as a base engine) and also add the 2.0-liter turbo four-cylinder from the ATS. Check out all the details on this new engine and watch a few videos (including GM's nifty tilt rig) by scrolling below.

GM extending warranties on Cadillac CTS-V and Chevy Camaro ZL1 for supercharger issue

Okay General Motors, we've sat by and watched you recall the compact cars, crossovers and pickup trucks, and aside from reporting on it, we've been fairly quiet. This, though, this will not do. We can almost tolerate the recalls on the bread-and-butter cars, but leave the performance vehicles alone.
According to a report from The Car Connection, GM has discovered a problem with the superchargers of the 6.2-liter V8s found in the Chevrolet Camaro ZL1 and the Cadillac CTS-V. Apparently, the issue rests around the internal bearing shaft grease, which can become contaminated (we aren't sure with what). If left unchecked, it'll first lead to a rattle at idle, which goes away under slight throttle. The real warning stage is when a high-pitched squeal develops, signaling that the bearing shaft has failed. Naturally, severe engine damage is the next step (although it's possible that the engine will also just refuse to turnover, although neither case is desirable).
According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue.

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.
