GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.

Expect the Cadillac XT3 small crossover in late 2018

Cadillac's sedan-heavy lineup can't complete in this crossover-crazy market, it seems. The Detroit News spoke to Cadillac boss Johan de Nysschen and found out some more details about the brand's plan to alter its lineup to cater more to current consumer tastes. It's no surprise that these plans would include a small crossover, because de Nysschen has been talking about a vehicle smaller than the XT5 like this since at least 2015. The report also pins the Fairfax Assembly Plant, where GM builds the Buick LaCrosse and the Chevrolet Malibu, as the site for what could be called the XT3's production. That's not an immediately obvious choice, since the LaCrosse and Malibu are based on the latest evolution of the Epsilon platform, known as E2XX. And the XT5 is based on a crossover version of that same platform (known as C2XX), while XT3 is expected to be smaller than the XT5. So perhaps there's a different assembly line going into Fairfax, or the C2XX platform can be significantly shortened. We assume that the XT3 would be built on a smaller platform, perhaps the Gamma II that underpins the Chevrolet Trax and Buick Encore – which are built in either South Korea or Mexico, depending on which market they are to be exported to. The Encore is selling very well for Buick, with sales figures increasing through late last year. Another possibility is the D2XX platform that underpins the Chinese-built Buick Envision and the GMC Terrain and Chevrolet Equinox, perhaps with assembly happening at the CAMI plant in Ontario. At this early stage, without confirmation of GM as to what platform the XT3 will use or where it will really be built, it's too early to say what the Fairfax rumor means. This isn't the first time we've heard about a small Cadillac crossover. Back in 2015, de Nysschen told us to expect it sometime in 2018. But later that year, speaking to Reuters, he posited that it'd be closer to 2019. The Detroit News says de Nysschen told them it'll launch in the second half of 2018, splitting the difference between what we'd heard previously. Remember, Cadillac's only two vehicles in the segment are the XT5 and Escalade. We know that the brand is almost certainly scrambling to fill the holes in that side of the lineup. We think a three-row crossover will slot between the two, probably called the XT7.

Cadillac CT6 beefs up with 400-hp twin-turbo V6

Cadillac's engine lineup is set to get a makeover led by the potent powerplants under the hood of the CT6. Our man Steven Ewing is onsite at an event in Detroit reporting all the details. Here's what we know so far: The CT6's top engine will be a 3.0-liter twin-turbo V6. It's the first twin-turbo with cylinder deactivation, which essentially makes the V6 able to convert to a V4 unit. Power will be 400 horsepower at 5,500 rpm and 400 pound-feet of torque at just 2,500 rpm. No word on what a potential CT6-V would get. The CT6 will also have a naturally aspirated V6 that Cadillac is claiming to be all-new. It's rated at 335 hp at 6,800 rpm and 284 lb-ft at 5,300 rpm. That's an improvement of 14 hp and nine lb-ft compared with today's 3.6-liter V6, and fuel economy increases nine percent. Cadillac says it's the highest output for a naturally aspirated V6 that's SAE-certified and runs on regular fuel. Both of these V6s will have stop/start technology and will be paired to with eight-speed automatic transmissions. The 3.6-liter V6 will also be used in the 2016 CTS and the 2016 ATS. Meanwhile, Ewing reports that Cadillac says the ATS-V is actually more powerful than initially announced, though there are no numbers to flesh that claim out as yet. The brand also plans to offer four- and six-cylinder diesel engines in various vehicles and new V8 options. The CT6 bows at the New York Auto Show. It will use an aluminum-intensive body that reduces weight by 198 pounds compared with a steel setup and continues Cadillac's creased design language used on the CTS and ATS models. The CT6 goes into production late this year in Detroit.
